Question 1

US rules require fibre content, country of origin, manufacturer identity (RN or name) and care instructions. EU rules require fibre composition under Regulation 1007/2011, REACH compliance, and since 13 December 2024 an EU responsible person under GPSR. The brand or importer is the legal labeler.

Accepted Answer

Direct answerFor the US: fibre content, country of origin, manufacturer identity (an RN number or name) and care instructions, all permanently attached. For the EU: fibre composition under Regulation (EU) 1007/2011, REACH compliance, and since 13 December 2024 an EU-based responsible person under GPSR. In both markets the legal labeler is the brand or importer, not the factory.What has to be on the garmentThe two markets overlap on fibre and care, then diverge on identity and on who is accountable. The table is the working checklist we use when a label artwork is submitted for approval.RequirementUnited StatesEuropean UnionFibre contentTextile Fiber Products Identification Act: generic names and percentagesRegulation (EU) 1007/2011: fibre names and percentages, ±3 percentage points toleranceCountry of originRequired on imported textile productsOrigin claims must be accurate; "made in" is not mandatory for all goodsManufacturer identityRN number, or name and addressName and address of the EU responsible person under GPSRCare instructionsCare Labeling Rule, 16 CFR 423: washing, bleaching, drying, ironing, warningsISO 3758 symbols; national rules apply in several member statesRestricted substancesCPSIA for children's wear; California Prop 65 warning where applicableREACH Annex XVII; GPSR safety and traceabilityChildren's safetyTracking label, lead and phthalate limitsEN 14682 drawcord and cord requirementsWhat we need from you before we sew a labelLabel content is the brand's legal statement, so we do not draft it. We need the approved artwork, the fibre percentages from the actual fabric and trim composition, the care symbols or text, the RN number or the EU responsible person's details, and the placement and size for each label.Fibre percentages have to come from the fabric and trim composition, not from the marketing description. A hoodie described as "cotton" with a polyester rib and poly drawcord still has to declare those fibres.What we produce and what we do notWe sew woven labels, printed care labels, heat-transfer labels and hangtags to the approved artwork, and we can add polybag warnings and carton marks. We check the artwork against the approved fibre list before production, because a label error is a recall risk, not a rework.What we cannot do is take legal responsibility for the label content. The brand or importer signs the artwork, and that signature is what the factory produces to.Field exampleA US launch of 600 poly-fleece hoodies needed four label elements: 80/20 cotton-poly composition, country of origin, the brand's RN number and four care symbols. The EU sibling order added the GPSR responsible person's name and address, a REACH statement in the technical file, and EN 14682 checks on the drawcord. Artwork was approved in three working days because the fibre list came from the fabric and trim card rather than from the product description.Numbers that matterUS: four core label elements — fibre, origin, identity (RN), careEU: fibre composition tolerance is ±3 percentage points under Regulation 1007/2011GPSR applies from 13 December 2024 and requires an EU-based responsible personCare symbols follow EN ISO 3758; keep the approved artwork with the order fileRelated questionsCan you support private label branding and packaging?How can T-shirts be customized with prints, embroidery, labels, and packaging?Can I receive an inspection report before my order ships?Can a third-party inspection company check my bulk order?Quality control and inspection at VANRD

Question 2

OEKO-TEX STANDARD 100 tests the finished article for harmful substances and is product-level. GOTS certifies organic fibre content plus environmental and social criteria across every processing stage, and is supply-chain-level. One answers safety, the other answers origin and process.

Accepted Answer

Direct answerThey answer different questions. OEKO-TEX STANDARD 100 tests the finished article for harmful substances and is granted per product, with no requirement for organic fibre. GOTS certifies organic fibre content and the environmental and social performance of every processing stage, from fibre to finished garment, and requires chain-of-custody documents at each step.Side by sideA garment can hold OEKO-TEX without a gram of organic cotton, and a GOTS garment also has to meet chemical limits — GOTS includes them, but goes further into fibre, water, energy and labour.DimensionOEKO-TEX STANDARD 100GOTSWhat is certifiedThe finished article and its componentsThe organic fibre and the processing chainFibre requirementNone≥70% organic; ≥95% for the "organic" gradeChain of custodyNot requiredRequired at every stage, with transaction certificatesChemical inputsTested against limit valuesMust come from the approved input listSocial criteriaNot coveredCovered, audited annuallyValidity12 months, product-specificAnnual audit and certificationWho holds itThe mill or garment maker for that articleEach certified operator in the chainWhat each one is good forOEKO-TEX is the practical answer for a brand that needs to state the garment is safe against a recognised limit list, including for children's wear through product classes I to IV. It is what a European retailer will normally ask for on a fabric and trim file.GOTS is the answer for an organic claim. It is also harder to arrange, because every operator in the chain has to be certified and each shipment needs a transaction certificate. A brand cannot decide to "add GOTS" at the packing stage.How to verify a certificate, and what we can provideOEKO-TEX certificates carry a number that can be checked in the OEKO-TEX buying guide, and the scope has to name the article or component. GOTS certificates can be checked in the public GOTS database, and the transaction certificate is the document that ties a specific shipment to a certified operator.Certificates sit with the mill, the printer or the trim supplier that holds them, not with the garment factory. We request the scope that covers your specific fabric, print paste and trims, check that the article description matches, and pass the documents with your order file. We do not describe VANRD as certified for a standard we do not hold.If a certificate's scope names a different quality code or a different mill, it does not cover your order, even if it is the same fibre.Field exampleA European kidswear brand needed OEKO-TEX product class I for a 320 GSM cotton hoodie. The fabric mill held a certificate covering the quality code, the print paste had a separate certificate from the printer, and the drawcord supplier provided its own. Three documents, one order file. On a later organic programme the same brand moved to GOTS and discovered the fabric mill was not certified, so the order had to be re-sourced before sampling could start.Numbers that matterOEKO-TEX product classes I-IV: baby, direct skin, outerwear, decorationGOTS requires ≥70% organic fibre, and ≥95% for the "organic" gradeOEKO-TEX certificates are valid for 12 months and name the articleGOTS needs a transaction certificate per shipment, not one certificate per yearRelated questionsWhat GSM fabric is best for custom t-shirt manufacturing?What is the difference between French terry and brushed fleece?What quality control checks matter most for custom streetwear production?Can a third-party inspection company check my bulk order?Quality control and inspection at VANRD

Question 3

Defects found in-line are repaired at the station. Units failing final inspection are sorted 100% and repaired or replaced before packing. After delivery, claims are handled against the batch code and photos within the agreed window, with replacement or credit depending on where the fault sits.

Accepted Answer

Direct answerHandling depends on when the defect is found. In-line defects are repaired at the station and the cause is logged. Units that fail final inspection are sorted 100% and repaired or replaced before packing. After delivery, a claim is checked against the batch code on the carton and the inspection report, and the outcome is replacement or credit depending on whether the fault is ours.Who handles what, and who paysThe principle is simple: a defect we caused is our cost at any stage; a defect caused after delivery is not. The grey area is wear and wash damage, which is why care labels and wash-test results are kept with the order file.StageActionCost carried byIn-line, during sewingRepair at the station, log the causeVANRDFinal inspection fail100% sort, repair or replace before packingVANRDAfter delivery, production faultReplacement in the next run or creditVANRDAfter delivery, not a production faultRepair quote or technical adviceBuyerWhat cannot be repairedSome faults are terminal: a hole in the body panel, a shade that is out of tolerance across the lot, a label with the wrong fibre content, or a decoration that has cured in the wrong position. These are replaced or credited, not repaired, because a repair would still leave a trace the customer can find.Repairs are also capped. If more than a small share of a lot needs repair, the honest answer is to remake the affected size rather than ship a garment that has been through the needle twice.Claims and traceabilityEvery carton carries a batch code that links to the cutting lot, the sewing line and the fabric roll. A claim with a photo and a batch code can be traced in a day; a claim with a photo alone usually ends in a negotiation.The claim window is set in the contract, typically 30 days from delivery, and decorated styles usually ship with 1-3% spare units so a small number of defects does not become a reorder.Field exampleA 2,400-piece tee order showed 1.8% wavy neck ribs at final inspection, just under the AQL but visible in a retail fold. We sorted 100%, set aside 43 pieces, replaced them from the 2% spare units packed with the order, and changed the rib attaching tension on the next run. No credit was needed and the delivery date held.Numbers that matter100% sort is triggered when majors exceed the agreed AQL, not when a single defect appears1-3% spare units are standard for decorated stylesClaim window typically 30 days from delivery, stated in the contractBatch code on every carton links to cutting lot, sewing line and fabric rollRelated questionsWhat quality control checks matter most for custom streetwear production?What causes a custom tracksuit sample to be rejected, and how can brands avoid it?Can a third-party inspection company check my bulk order?What measurement tolerances are acceptable in bulk clothing production?Quality control and inspection at VANRD

Question 4

The lot is frozen and compared point by point against the signed approved sample and spec. The deviation is quantified, the cause traced, and the remedy is rework, remake or a commercial adjustment. The contract decides who carries the cost, which is why the approval record matters.

Accepted Answer

Direct answerThe lot is frozen and compared point by point against the signed approved sample and spec — not against memory or a photo. We quantify how many pieces are affected, trace the cause to a lot, a cutting batch or a process, and then agree a remedy: rework, remake, or a commercial adjustment. Who pays depends on where the fault sits, and the contract decides that.Step by stepThe first 48 hours decide the outcome. If the goods are still in our warehouse the options are wide; once they are in a container or in your warehouse, the practical options narrow to replacement and credit.StepActionEvidence produced1.

RemedyRework, remake, credit or rejectionWritten agreement with datesWhat counts as not matchingA mismatch is a measurable difference from the approved standard: shade beyond the agreed Delta E, measurement outside the tolerance in the spec, a substituted trim or label, decoration in the wrong position or size, or a fabric hand and weight that no longer matches the approved quality code.Normal variation inside tolerance is not a mismatch. Garment-dyed styles vary shade across a lot by nature, which is why the tolerance has to be agreed in Delta E before the wash recipe is approved, not after the goods arrive.How the remedy is decidedIf the deviation is a production error on our side, rework or remake is at our cost, and we cover the freight consequence of the delay. If it comes from a change the buyer approved late, from buyer-supplied fabric, or from a wash standard the buyer signed off, the cost is shared or carried by the buyer as the contract sets out.Either way the remedy is written down with dates before work starts, so there is no second argument about what was agreed.Field exampleA 1,000-piece hoodie order arrived with a shade reading Delta E 2.1 against the approved standard, where the agreed tolerance was 1.0. The cause was a different dye lot of the same quality code. 300 pieces were re-dyed to the standard, the remaining 700 were accepted with a credit per piece, and the mill was put on notice that lot changes must be flagged before dyeing.Numbers that matterShade tolerance: Delta E ≤1.0 for solid shades, ≤1.5 for garment-washed stylesAssessment within 48 hours of the claim, with 3 pieces per size comparedRework typically takes 7-14 days; remake follows the 25-35 day bulk lead timeKeep the approved sample and signed spec — without them a claim becomes an opinionRelated questionsHow can brands control sample-to-bulk consistency in custom clothing production?How can brands keep hoodie fit, fabric weight, and wash effect consistent across reorders?Can a third-party inspection company check my bulk order?How do you test garment shrinkage after washing?Quality control and inspection at VANRD

Question 5

Yes. Every order gets a pre-shipment report as a PDF 24-48 hours before dispatch, covering the AQL result, the measurement chart, defects with photos, packing data and a pass or fail decision. The shipment does not leave without a released report.

Accepted Answer

Direct answerYes. Every order produces a pre-shipment report before dispatch, issued as a PDF within 24-48 hours of inspection. It contains the AQL result, the measurement chart against spec, every defect found with photos, the packing and carton data, and a clear pass, conditional pass or fail decision. The order is not released for shipping without it.What the report containsThe report is written so that someone who has never seen the order can understand what was checked and what was found. It references the approved sample and the signed spec version, because a report against an outdated spec is worse than no report.SectionContentsOrder dataPO number, style, colourways, size breakdown, quantityInspection dataDate, inspector, AQL level, sample size drawn, cartons openedMeasurements5 pieces per size measured against spec, with pass or fail per pointDefectsCritical, major and minor counts, location, photo per defect typePackingPieces per polybag and carton, carton dimensions and weight, shipping marksResultPass, conditional pass or fail, plus the action requiredWhat the result actually meansA pass means the lot met the agreed AQL at the agreed level. It does not mean zero defects — a 2.5 AQL accepts a defined number of majors in the sample by design, and the customer should know that number before the order starts.A conditional pass means the lot ships only after a named action is completed and evidenced, usually a 100% sort or a specific repair. A fail means the lot is held, and we issue a corrective action with a date.Who else can see itThe report is yours to forward to your customer or to your own inspection company as a starting point. If you book a third-party inspection, our report and theirs sit side by side, and any difference between them is worth investigating before the container is loaded.Reports are kept against the order for 12 months, so a claim six months later can be checked against what was actually inspected.Field exampleOn an 800-piece jacket order the pre-shipment report flagged 12 majors: the zipper pulls were the right design but the wrong finish, gunmetal instead of matte black. The shipment was held for two days while 800 pulls were replaced from stock and 60 pieces were re-pulled. The re-inspection passed, and the report is what made the difference visible before the goods reached the customer's warehouse.Numbers that matterReport issued within 24-48 hours of inspection, before dispatchStandard levels: AQL 2.5 major, 4.0 minor, zero criticalOne inspection day covers up to roughly 3,000 piecesReports retained against the order for 12 monthsRelated questionsWhat quality control points should brands check before bulk apparel production?Can I receive production updates or photos during manufacturing?How do you test garment shrinkage after washing?What common stitching defects should brands look for in samples?Quality control and inspection at VANRD

Question 6

Pilling comes from short fibres working loose and tangling on the surface. Combed or combed ring-spun yarn, longer staple, firmer twist and lighter brushing all reduce it, and a Martindale or random-tumble test at grade 3-4 or better confirms it before bulk.

Accepted Answer

Direct answerPilling is loose fibres tangling on the surface, so the fix is at the yarn: use combed or combed ring-spun cotton, longer staple, a firmer twist, and brush the inside less. Then confirm it with a Martindale or random-tumble test and accept nothing below grade 3-4. A softer hand-feel and lower pilling pull in opposite directions, so the choice has to be made at sampling.Where pilling actually comes fromShort fibres escape the yarn during abrasion, roll into small balls and stay anchored to the surface. Carded cotton with a high short-fibre content pills faster than combed cotton, and a loosely twisted yarn releases fibres faster than a firm one. Brushing the inside of a fleece improves the hand-feel but also raises more fibre ends.Abrasion is not evenly distributed. Underarm, cuffs, the lower back where a bag rubs and the inside of the thigh are where pilling shows first, which is why a wear test on the whole garment hides the problem until the customer finds it.LeverEffect on pillingTrade-offCombed instead of carded yarnLarge reduction, fewer short fibres5-10% higher yarn costLonger staple cottonFewer fibre ends escapeFibre availability and priceFirmer yarn twistBinds fibres into the yarnSlightly crisper hand-feelLighter inside brushingLess surface nap to pillLess immediate softnessAnti-pilling finishMeasurable improvementHand-feel and shade can shiftPolyester blendBetter abrasion resistanceLoses natural hand and breathabilityHow to test it before bulkTwo methods cover most buyer requirements. Martindale to ISO 12945-2 runs a set number of rubs, usually 2,000, against a standard abradant. The random tumble test, ASTM D3512, puts the sample in a chamber with cork or pumice for 30 minutes. Both produce a grade from 1 to 5, where 5 is no pilling.We test on the finished fabric, not greige, because brushing, washing and softening all change the result. For a brushed fleece the inside face is graded separately from the outside, since that is where the customer sees pilling first.What to write into the specPut a grade and a method in the spec, not an adjective. "No pilling" cannot be inspected; "Martindale ISO 12945-2, 2,000 rubs, grade 4 minimum, inside face" can be measured, argued and repeated.If the brand sells at a premium price point, grade 4 is the realistic target. At volume price points grade 3 is common, and grade 3-4 is a sensible middle.Field exampleA 420 GSM brushed fleece hoodie graded 2-3 on the inside face after five home washes, which the brand's returns data had already flagged. We moved the shell to combed ring-spun cotton, reduced the brushing passes and added an enzyme finish. The next lot graded 4 at 2,000 Martindale rubs, with a hand-feel the brand accepted on the first round.Numbers that matterPilling scale 1-5, where 5 is no pilling; grade 3-4 is the usual commercial floorMartindale test to ISO 12945-2 at 2,000 rubs, or random tumble to ASTM D3512 for 30 minutesCombed yarn adds roughly 5-10% to yarn cost and is the single biggest leverGrade the inside face of a fleece separately — that is where pilling appears firstRelated questionsWhat GSM fabric is best for custom t-shirt manufacturing?Does higher GSM always mean better fabric quality?Can a third-party inspection company check my bulk order?What measurement tolerances are acceptable in bulk clothing production?Quality control and inspection at VANRD

Question 7

Eight faults cause most sample rejections: skipped stitches, unbalanced tension, uneven stitch density, seam puckering, seam grin, raw edges, missing backtack and twisted side seams. Check them inside out, count stitches over 10 cm, and pull the seam before you approve.

Accepted Answer

Direct answerLook for eight faults, because they account for most rejections: skipped stitches, unbalanced tension, uneven stitch density, seam puckering, seam grin, raw or frayed edges, missing backtack and twisted side seams. All eight are visible in ten minutes if you turn the garment inside out, count stitches over 10 cm and pull the seam by hand.The eight faults and what causes themMost stitching defects are machine settings or operator habits, not bad fabric. That matters because a setting can be corrected for the whole lot, while a fabric fault cannot.DefectWhat you seeUsual causeSkipped stitchGaps in an otherwise straight seamNeedle size, hook timing, wrong thread for the fabricUnbalanced tensionLoops or a birdnest on one sideBobbin or upper tension set for a different fabricUneven stitch densityStitches run 8 then 12 per inchOperator speed, feed dog pressure, no guideSeam puckeringRippled seam line after sewingDifferential feed, damp fabric, too much tensionSeam grinStitches open and show white when pulledLow stitch density, thin fabric, no topstitchRaw or frayed edgeLoose threads inside the garmentEdge not overlocked or boundMissing backtackSeam opens at the start or endOperator skipped the reverse stitchTwisted side seamLeg or body spirals when wornCutting off-grain or panels mismatched at sewingHow to check a sample properlyTurn it inside out first. Most of these faults are hidden on the outside by design. Count stitches over 10 cm on the main seams: 10-12 per inch on knits and 8-10 on wovens is the working range, and a seam that varies by more than two stitches along its length will fail in wear.Then pull the seam across its width with both hands. A seam that opens enough to show the fabric edge, or that feels weak before the fabric itself gives, is a seam grin and will fail at the first wash. Backtack should be 1-1.5 cm at every seam end that carries load.What we check before a sample shipsEvery development sample goes through a 100% inside-out inspection on the first piece, then a documented check on the rest of the set. Seam strength is tested on the main seams and should reach at least 80% of the fabric's tensile strength, so the seam does not become the weak point.Findings are photographed at the machine, not after the sample is packed, so the operator who made it can see the fault.Field exampleA 500-piece sweatpants order showed skipped stitches at the crotch seam on about 3% of pieces. The cause was a needle that was too fine for the 400 GSM fleece and a thread that was too stiff for the looper. Switching to a 14/90 needle and a softer Tex 40 polyester thread took the rate to 0.4% on the next 200 pieces, with no change to the fabric or the pattern.Numbers that matterWorking stitch density: 10-12 per inch on knits, 8-10 per inch on wovensBacktack 1-1.5 cm at load-bearing seam endsSeam strength target: at least 80% of fabric tensile strengthInspect 100% of the first pieces inside out, then sample per AQLRelated questionsHow can brands reduce defects in custom puffer jacket production?What measurement tolerances are acceptable in bulk clothing production?Can a third-party inspection company check my bulk order?How do you test garment shrinkage after washing?Quality control and inspection at VANRD

Question 8

We test to AATCC 135 for the US or ISO 6330 with ISO 5077 for the EU: mark a 50 cm gauge on length and width, run three wash cycles at the care-label temperature, dry as the label states, and re-measure. Length and width are reported separately, because a knit rarely shrinks the same in both directions.

Accepted Answer

Direct answerShrinkage is measured, not estimated. We mark a 50 cm gauge on the length and width of the garment or a sewn panel, run three wash cycles at the temperature printed on the care label, dry it the way the label says, and re-measure the same gauge. The result is reported separately for length and width as a percentage change, and that number decides the pattern allowance.The two methods buyers ask forAATCC 135 is the American route and is what a US buyer will normally request. ISO 6330 with ISO 5077 is the European equivalent. Both do the same thing: a defined wash, a defined dry, a measured change. The test is only comparable if the wash temperature, detergent and drying method are stated alongside the result.Care labels matter here. A garment tested at 40 °C and tumble dried will shrink noticeably more than the same garment washed at 30 °C and line dried. Quoting a shrinkage figure without the test conditions is meaningless.Fabric routeMethodCyclesTypical acceptanceCotton knit, untreatedAATCC 135 / ISO 63303≤5% length, ≤3% widthCotton knit, compactedAATCC 135 / ISO 63303≤3% lengthCotton woven / denim, sanforisedISO 63303≤2-3% lengthCotton-polyester blendAATCC 135 / ISO 63303≤2%Why length moves more than widthIn a knitted panel the loops are pulled along the length during finishing, so the length has more stored distortion to release in the first wash. Width is held by the Wales of the knit and moves less. This is why a hoodie can lose 4 cm of body length and almost nothing across the chest.Garment dyeing and washing add a second shrink on top of the fabric shrink. A piece that was already garment washed needs its own test, not the greige fabric result.What we do with the numberThe result goes into the pattern as an allowance before bulk cutting, and into the care label as the wash instruction the garment can survive. If a fabric fails the target, the options are compaction at the mill, a pre-shrink wash, a blend change, or a pattern allowance — in that order of cost.For repeat orders we re-test whenever the mill changes lot or finish, because the same quality code from a different lot can shift half a percent.Field exampleA 380 GSM cotton loopback hoodie measured 4.8% length shrinkage after three washes at 40 °C, above the 3% the brand needed for its size chart. The mill compacted the next lot and we ran a garment wash trial, which brought it to 2.4%. We then added 1 cm to the body length in the pattern so the garment lands on spec after the customer's first wash.Numbers that matterGauge length 50 cm, marked on both length and width before washingThree cycles at the care-label temperature, usually 30-40 °C, with the stated drying methodReport length and width separately — a single average hides the problemWorking acceptance: ≤3% for compacted cotton knits, ≤2% for cotton-poly blendsRelated questionsHow can brands reduce shrinkage in cotton garments?How can brands keep hoodie fit, fabric weight, and wash effect consistent across reorders?Can a third-party inspection company check my bulk order?What common stitching defects should brands look for in samples?Quality control and inspection at VANRD

Question 9

Knitted garments normally allow plus or minus 1 cm on body length, chest, waist and hip, and plus or minus 0.5-0.6 cm on shoulder, sleeve and neck. Woven styles run tighter on critical points. Tolerances must be written per measurement point in the spec, never as one blanket number.

Accepted Answer

Direct answerThere is no single number: tolerance is set per measurement point. For knitted streetwear we work to plus or minus 1 cm on body length, chest, waist and hip, and plus or minus 0.5-0.6 cm on shoulder, sleeve length, neck width and cuff height. Woven styles are held tighter on the points that carry the fit. Every point has its tolerance printed in the spec before sampling starts.Tolerance by measurement pointThe figures below are the working tolerances we put in a spec sheet. They assume the garment is measured flat, relaxed, 24 hours after production and before packing. A brand can tighten them, but tightening has a cost: tighter tolerance means more pieces reworked and a slower line.Measurement pointKnit (hoodie, tee, sweatpants)Woven (jacket, shirt, denim)Body length±1.0 cm±0.8 cmChest, 1" below armhole±1.0 cm±0.8 cmWaist and hip±1.0 cm±0.8 cmShoulder width±0.5 cm±0.4 cmSleeve length±0.6 cm±0.5 cmNeck width±0.5 cm±0.4 cmCuff and hem height±0.3 cm±0.3 cmWhy knits get more room than wovensA knitted panel relaxes after it leaves the cutting table and again after the first wash. A 400 GSM loopback hoodie can grow 0.5-1 cm across the chest simply by being folded and stacked for two days. Woven panels are dimensionally stable, so the tolerance can be tighter without punishing the line.This is also why the measurement must be taken after relaxation, not straight off the machine. Measuring a hoodie still warm from the iron gives a number that will not repeat tomorrow.How the tolerance is checked in bulkOur QC measures a minimum of three pieces per size per colour at the start of production, then five pieces per size at final inspection. Every measurement is logged against the spec, and any point outside tolerance is flagged by size and colour so the fault can be traced to a cutting lot.If two or more pieces in a size are out by more than the tolerance, the size is re-measured after 24 hours. If it is still out, the pattern is corrected before the rest of the lot is cut.Field exampleOn a 400 GSM oversized hoodie with a 62 cm chest spec, the first bulk measurement showed 61.2-62.7 cm on most pieces, but six pieces read 63.0-63.4 cm. Re-measured after 24 hours of relaxation, four of the six fell back inside tolerance and two stayed out. Those two were re-cut. The cause was a cutting marker that had been nudged 4 mm at the side seam, not a sewing fault.Numbers that matterWorking tolerance: ±1 cm on body points, ±0.5-0.6 cm on detail points for knitsMeasure flat and relaxed, 24 hours after production, at 20 ±2 °C and 65 ±4% relative humidityMinimum 3 pieces per size and colour at production start, 5 pieces per size at final inspectionA 4 mm marker error becomes a 4 mm error on every piece in that lot — cutting is checked before sewingRelated questionsWhat is the difference between a fit sample, PP sample, TOP sample, and final inspection?How can brands control sample-to-bulk consistency in custom clothing production?Can a third-party inspection company check my bulk order?How do you test garment shrinkage after washing?Quality control and inspection at VANRD

Question 10

Yes. Buyers can appoint SGS, Bureau Veritas, Intertek, TUV or QIMA for an in-line or pre-shipment inspection. VANRD provides work-in-progress access, measurement sheets, packing lists and cartons, and acts on the findings. The inspection fee is paid by the buyer and booking needs 3-5 working days.

Accepted Answer

Direct answerYes. You can appoint any inspection company you like, and we will not restrict access. Most buyers book SGS, Bureau Veritas, Intertek, TUV or QIMA for a during-production inspection or a pre-shipment inspection. The inspector sees the same order file, measurement chart and cartons that our own QC team works from, and any findings are reworked and re-checked before the shipment leaves.When to book the inspectionThe stage you choose changes what the inspector can still influence. A during-production inspection catches construction and measurement problems while the line is still running; a pre-shipment inspection confirms the packed goods but can only trigger rework, not correction of the pattern.In practice most brands book one pre-shipment inspection on the first order and move to during-production checks once volumes grow, because a defect found at 40% completion costs a repair, while the same defect found after packing costs a shipment delay.StageWhat the inspector seesWhat can still changeDuring production (DUPRO)Cut and sewn work in progress, first finished pieces, in-line recordsPattern, construction, measurements, trim placementPre-shipment (PSI)100% packed cartons sampled to AQL, packed quantitiesRework, replacement, repacking — not the patternContainer loading (CLS)Carton count, marks, loading conditionLoading sequence onlyWhat we prepare for the inspectorAn inspection only works if the inspector is measuring against the same document the factory used. Before the visit we hand over the signed spec, the approved sample, the measurement chart with tolerances, the approved artwork and trim card, the packing list and the carton marks.Our QC team attends the inspection and signs the same report. If the inspector raises a defect we disagree with, we resolve it against the approved sample on the table rather than by email afterwards.What happens to the findingsFindings are sorted into critical, major and minor. Critical defects — wrong fibre content, wrong label content, unsafe trims — are always refused. Major defects trigger a 100% sort of the affected colour or size, and minor defects are handled by repair or replacement.Where the finding is our production error, the rework and any re-inspection we caused are at our cost. Where it comes from a change the buyer requested after approval, the cost sits with the change.Field exampleA German brand booked a Bureau Veritas pre-shipment inspection on 1,200 brushed fleece hoodies at AQL 2.5. The inspector found 8 major defects, all uneven embroidery placement on the chest logo, and the shipment was held. VANRD sorted 100% of the order, re-framed the embroidery on 34 pieces, replaced 6, and passed the re-inspection three working days later.

Yes, at agreed milestones rather than at random. The practical set is four points: after fabric inspection, after cutting, at in-line sewing, and before packing. Each update should carry photos plus a quantity status, so you can catch a problem while it is still cheap to fix.

Accepted Answer

Direct answerYes — at agreed milestones. The four that matter are: after fabric inspection (shade and weight confirmed), after cutting (quantity and panel check), at in-line sewing (first finished pieces), and before packing (final quantity and carton status). Each update should include photos plus a number, because a photo without quantity cannot tell you whether you are on schedule.Why milestone updates beat daily messagesDaily messages create noise and still miss the moments where intervention is possible. Milestones map to the points where a problem is still fixable: a shade issue at fabric stage is a re-dye conversation; the same issue at packing is a claim.A useful update has three parts: what stage, how many pieces, and what is the next gate. Photos support the claim, they do not replace it.MilestoneWhat you receiveWhat you can still changeFabric inspectionShade and weight photos, roll countFabric or shade, before cuttingAfter cuttingCut quantity by colour and sizeQuantity mix, before sewingIn-line sewingFirst finished pieces, key seamsConstruction detailsBefore packingFinal quantity, carton marksPacking and shipping onlyHow to set this up in the orderWrite the update schedule into the order confirmation with the responsible contact.

Question 12

Check five things before a deposit: evidence of comparable production, the real factory floor, documented QC steps, references that answer specific questions, and whether the written spec matches what the sales conversation promised. Video calls and a sample order settle more than brochures.

Accepted Answer

Direct answerEvaluate on evidence, not presentation. Ask for comparable production photos or video from the actual line, a live video walk-through of the workshop, the QC checkpoints written down, and a reference customer who can answer specific questions about defects and delays. Then place a paid sample order and judge the spec sheet against what arrives. At VANRD this is the same path every new buyer takes before a deposit.Five checks that separate a factory from a traderA trading company can quote well and deliver badly, because the line it promises is not its own. The fastest filter is a live video call walking through cutting, sewing and finishing — with the machine types visible.Second filter: ask what they will not do. A factory that says “we do not run bonded fabrics” or “we cannot print on nylon” is describing real capability. One that says yes to everything is describing sales.CheckWhat good looks likeRed flagComparable productionPhotos or video of similar garments on the lineOnly stock catalogue imagesLive walk-throughCutting, sewing, finishing in one callRefusal or delayDocumented QCNamed checkpoints with AQL level“We check everything”ReferenceA customer who describes a defect and how it was handledOnly testimonialsSpec accuracyWritten spec matches the sampleVerbal promisesThe cheapest test is a sample orderA sample tests pattern-making, fabric sourcing, communication speed and finishing at once.

Question 13

All four approvals must be closed before bulk cutting starts, and in a fixed order: fabric quality, then colour (lab dip), then decoration standard, then trims. Approving after cutting has started converts every change into waste or delay.

Accepted Answer

Direct answerClose all four approvals before cutting starts, in a fixed order: fabric quality first (quality code, GSM, composition), then colour (lab dip or bulk swatch under D65), then decoration (print or embroidery standard on the actual fabric), then trims (zippers, cords, labels). At VANRD this is the pre-production approval gate — bulk timing starts from that approval, not from the PO date.Why the order mattersFabric choice changes how colour reads and how decoration behaves. Approving a print before the fabric is fixed means re-approving it later. Approving a lab dip before the fabric quality is fixed means the dip may not match the bulk base at all.Once cutting begins, a colour change is not an edit — it is a re-cut or a re-dye, and both cost more than the delay would have.OrderApprovalWhat you are signing off1Fabric qualityQuality code, GSM, composition, shrinkage2ColourLab dip or bulk swatch under D653DecorationPrint or embroidery standard on production fabric4TrimsZipper, cord, labels, packaging sample5Pre-production sampleBulk version confirmed against the approved sampleWhat “approval” should mean in writingAn approval is a dated decision against a physical standard, recorded in writing. “Looks good” in a chat message is not an approval, and it will not settle a dispute three weeks later.Keep the approved standard sealed, physically or photographically, with the shade reference noted.Field exampleA brand approved the print first and changed the fabric a week later.

Question 14

Grading turns the approved base size into the full size range using measured increments per point of measure. It is confirmed on a graded size set — not on the base sample alone — and re-measured after washing if the fabric shrinks.

Accepted Answer

Direct answerGrading converts the approved base size into the full range by applying measured increments to each point of measure. Before bulk, VANRD issues a size set (usually the smallest, base and largest sizes) and a measurement sheet with tolerances; the set is measured again after a wash cycle when the fabric shrinks. Bulk is then inspected against that sheet, not against the base sample alone.What grading actually changesChest, body length, shoulder, sleeve, hem and neck opening each move by their own increment. A hoodie may grade 5 cm across the chest per size but only 2 cm in body length — the increments are not uniform, and they must follow the fit intent.This is why a base-size sample alone cannot prove a range. A size L that fits does not guarantee an XL that still looks oversized rather than simply bigger.CheckpointWhat to confirmWhenBase size sampleSilhouette, fabric hand, detailsSamplingGrading rulesIncrements per point of measureBefore size setSize setSmallest, base, largestBefore bulkTolerancesAcceptable deviation per pointWith size setPost-wash measurementShrinkage applied to gradingBefore bulk approvalWhere size complaints come fromTwo causes dominate: grading increments copied from a different fit block, and shrinkage applied to the base size but not to the grade. Both show up as “the larger sizes are off” rather than “everything is off”.Specify tolerances in the tech pack. Without them, measurement disputes have no reference.Field exampleA brand's XL measured 2 cm short against the size set. The cause was shrinkage applied to the base size only, so the increment carried the error upward.

Question 15

A sample is a one-off: its own pattern, its own cutting, a single garment through every operation, and often fabric bought in small quantity. A bulk unit shares pattern, cutting, setup and fabric across hundreds of pieces — so the same garment costs several times more as a single sample than inside a 100-piece run.

Accepted Answer

Direct answerBecause a sample carries all the fixed costs of a style on one garment. The pattern, the marker, the cutting setup, the machine settings, the artwork setup and the finishing are the same whether you make one piece or five hundred — but at one piece they land entirely on that sample. Add small-quantity fabric and the sample price is several times the bulk unit price by arithmetic, not by margin.Where the money goesPattern making and grading, marker making, fabric in short lengths, trims bought below their own minimums at retail-equivalent prices, decoration setup for a single piece, and the labour of running a garment through every station once.In bulk those costs divide across the run. At 100 pieces the setup is already diluted by two orders of magnitude compared with a single sample.Cost elementSampleBulk (100 pcs)Pattern and markerFull cost on one pieceSpread across 100FabricShort length, higher rateRoll quantity, mill rateDecoration setupFull setup on one pieceSetup spread across piecesLabourOne garment, all operationsLine efficiency appliesResultHighest unit costLowest unit costWhat you are really buyingA sample answers questions bulk cannot: does the fabric behave, does the pattern hold the silhouette, does the artwork read at real size. Discovering those answers at bulk stage costs the whole run.The productive way to look at it: the sample fee buys the right to run bulk once, correctly.Field exampleA brand compared a USD 45 sample with a USD 18 bulk unit and assumed a margin gap. Breaking it down, the sample carried the full pattern, a single-garment decoration setup and retail-rate trims; the bulk unit shared those across 100 pieces.

Question 16

Yes — every order starts with a sample; bulk never runs without an approved pre-production piece. The sample is charged as a separate development item and takes 7–10 days after spec and materials are confirmed. One to three rounds is normal before approval.

Accepted Answer

Direct answerYes. No bulk run starts without an approved sample. The sample is produced as a separate development item — typically 7–10 days after the spec and materials are confirmed — and it is charged separately because it carries its own pattern, cutting and finishing. One to three rounds is normal; each revision round adds roughly 7–14 days.What the sample actually provesThe sample is not a preview, it is the reference. It fixes the measurements, the fabric hand, the stitch density, the artwork position and the trims. Bulk is measured against it.That is why changing fabric after sample approval is the most expensive mistake in the process: the fit, the shrinkage allowance and the grade all need to be rebuilt.StagePurposeTypical durationFit samplePattern, measurements, silhouette7–10 daysRevision roundAdjust fit or details7–14 days eachPre-production sampleConfirm bulk fabric, trims and decoration7–10 daysBulkProduction against the approved sample25–35 daysKeeping sample rounds to a minimumMost extra rounds come from an incomplete brief, not from the factory. Send measurements from a garment you already sell, state the fabric weight, and mark the artwork position on a photo.Change one variable per round. If you change fabric and fit together, you cannot tell which change produced the result.Field exampleA Toronto brand needed a boxy hoodie with a dropped shoulder. Round one came back too close to the body because the brief said “oversized” without measurements.

Question 17

At VANRD the MOQ is 100 pieces per style and color. It is a per-colour minimum, not a per-order minimum: a two-colour programme starts at 200 pieces, a four-colour programme at 400. Sizes can be mixed inside a colourway as long as that colour reaches 100; colours cannot be combined to reach it.

Accepted Answer

Direct answerOur minimum is 100 pieces per style and color. It is a per-colour minimum, not a per-order minimum — a two-colour programme starts at 200 pieces, four colours at 400. Sizes can be mixed inside a colourway as long as the total for that colour reaches 100. Different colours cannot be combined to reach the minimum, because each colour is a separate dye and cutting lot.Why the minimum existsCutting, dyeing, pattern development, trims with their own supplier minimums and a separate sampling round all have to be carried by the first order. At 100 pieces those costs sit on a small quantity; at 500 the same setup spreads across five times as many units, which is why unit price falls as volume rises.The minimum is also a quality mechanism: below roughly 100 pieces a colour, the cutting and sewing lines are not set up long enough to hold consistency across sizes.ProgrammeTotal piecesHow it is calculated1 colour100100 per color2 colours200100 × 24 colours, same style400100 × 42 styles, 2 colours each400100 × 4 colourwaysWhat can push the minimum higherCustom-dyed colourways carry their own mill dye-lot minimum on top of the garment minimum. Specialist constructions, bonded fabrics, and trims with high supplier minimums can also raise it.If your first drop is smaller than the minimum, the practical route is to launch fewer colourways at 100 pieces each rather than more colours at 50.Field exampleA Seoul label wanted six colourways at 60 pieces each. VANRD mapped it to two colours at 100 pieces for the launch and kept the other four as a second wave, which held the per-colour rule and kept the unit price inside their target.Numbers that matterMOQ: 100 pieces per style and colorSizes can be mixed within a colourway; colours cannot be combinedUnit price falls as volume rises because fixed costs spreadCustom-dyed colours add a mill dye-lot minimum on topRelated questionsCan a new apparel brand start OEM/ODM production without a large order?Can I order a single prototype before bulk production?How do I start working with a custom clothing manufacturer?What information should I provide to get an accurate manufacturing quote?How the VANRD production process runs, step by step

Question 18

Yes — most cut-and-sew factories source fabric, trims and accessories as part of the programme, either from stock ranges or through their mill and trim suppliers. What matters is who owns the specification, who carries the minimum, and whether the trim is recorded on the same spec sheet as the garment.

Accepted Answer

Direct answerYes. A full-package factory sources fabric, trims and accessories as part of the order: shell fabric, lining, rib, zippers, drawcords, eyelets, labels, hangtags and polybags. The important questions are not whether it can be done, but who carries the mill minimum, who approves the trim standard, and whether every component is recorded on one spec sheet. At VANRD these are consolidated into a single material record per style so a reorder does not silently change a zipper.What “full package” actually coversFabric and lining come from mills; rib and cuff from knit suppliers; zippers, snaps and cords from trim houses; labels and hangtags from print suppliers. Each has its own minimum and lead time, and those minimums do not disappear because you are buying through a factory.A factory with established suppliers can often buy below the mill minimum by combining your order with other programmes — but that only works on qualities it already carries.ComponentTypical constraintWhat to lockShell fabricMill minimum per colourQuality code, GSM, composition, shadeRib and cuffDyed to match shellShade match under D65Zippers and snapsBrand and finish optionsBrand, tape colour, pull styleLabels and hangtagsPrint minimumsArtwork approval, placementPackagingCarton size and weightPolybag spec, carton marksThe reorder risk nobody plans forIf a trim is not written down, the next production run will use whatever the factory has.

Question 19

Six inputs decide a quote: garment style, fabric and GSM, colourways, quantity per colour, decoration method, and packaging with delivery date. Missing any one turns a firm number into a range — and ranges are what cause disputes at PO stage.

Accepted Answer

Direct answerTo get a firm number rather than a range, send six inputs: the style or reference garment, fabric and GSM (or accept the factory's recommendation), the number of colourways, quantity per colour, the decoration method and artwork, and packaging plus delivery date. At VANRD a quote is built from those six; if one is missing we quote a band and flag the assumption in writing.The six inputs, and why each one moves the priceStyle sets the pattern and the sewing operations. Fabric and GSM set the material cost per unit. Colour count sets the dye and cutting lots. Quantity sets how fixed costs spread. Decoration sets process time. Packaging and delivery set freight weight and mode.Ask for the quote broken down by those lines rather than one number. A breakdown shows immediately whether the difference between two suppliers sits in fabric, labour or freight.InputWhy it changes the priceStyle and constructionNumber of panels and sewing operationsFabric and GSMMaterial cost per garment; heavier costs more and ships heavierColourwaysDye lots, cutting lots, minimumsQuantity per colourFixed cost spreading; 100 vs 500 changes unit priceDecorationScreen setups, embroidery stitch count, patch makingPackaging and deliveryPolybag, carton, hangtag, freight modeWhat a trustworthy quote looks likeIt states the fabric spec, the quantity basis, the incoterm, the validity period and what is excluded. A quote without a validity date is not a quote — cotton and freight move.It should also separate sample cost from bulk cost, because these are different transactions with different economics.Field exampleA German label asked for pricing on “2,000 hoodies”. Without colourways, the number could not be fixed: two colours meant two dye lots, six colours meant six. Once the mix was set at three colours and the fabric fixed at 380 GSM loopback, the quote moved from a 20% band to a firm unit price.Numbers that matterQuote accuracy depends on quantity per colour, not total quantity aloneA quote without a validity period cannot be heldSeparate sample and bulk pricing — they are different transactionsAsk for a line breakdown to compare suppliers fairlyRelated questionsWhat should brands prepare before requesting a performance tracksuit quote?What affects the cost of custom jacket production?What is the minimum order quantity per style and color?How do I start working with a custom clothing manufacturer?How the VANRD production process runs, step by step

Question 20

Start with a written brief, not a price request: garment type, target quantity, fabric and GSM, colours, sizes, artwork and delivery date. That brief becomes the tech pack, the quote and the order confirmation. At VANRD the sequence is brief, fabric and trim confirmation, sample in 7–10 days, then bulk in 25–35 days after approval.

Accepted Answer

Direct answerStart with a written brief, not a price question. Send the garment type, quantity per style and colour, fabric and GSM direction, size range, artwork and target delivery date. That one document drives the quote, the sample and the production plan. At VANRD the sequence is: brief and quantity confirmed, fabric and trims selected, sample produced in 7–10 days, then bulk production in 25–35 days after pre-production approval.What the first message should containA factory cannot quote without quantity and construction. “How much for a hoodie?” has no answer, because the same silhouette ranges from a 280 GSM basic to a 480 GSM bonded piece with custom trims. The faster your brief is specific, the faster a real number comes back.If you do not have a tech pack, send reference images, a physical sample, or the closest product you have seen.

Question 21

Screen printing wins on cost per unit and colour opacity at volume, and is the standard for bold streetwear graphics. DTG suits small runs and photographic detail on cotton. DTF handles fine full-colour artwork on blends and synthetic fabrics, with a slightly raised hand-feel.

Accepted Answer

Direct answerChoose by artwork, quantity and fabric, not by preference. Screen printing is the cheapest per unit at volume and gives the most opaque, durable result on bold graphics. DTG is best for small runs and photographic detail on cotton, but ink cost per unit stays high. DTF handles fine full-colour work on cotton blends and synthetics, with a slightly raised film hand-feel. At VANRD the method is chosen after the fabric and artwork are fixed, because the same file can succeed on one and fail on another.Side-by-sideThe decision usually comes down to three questions: how many colours are in the artwork, how many pieces you are printing, and what the fabric is. Screen printing needs a screen per colour, so setup cost is high and unit cost falls with volume. DTG and DTF have almost no setup, which makes them viable at small quantities but more expensive per piece at scale.Screen printDTGDTFBest quantity100+ for 1–3 colours;300+ for 4+ colours1–501–200 (viable to 500)Colours1–6 spot coloursUnlimited, photographicUnlimited, photographicFabricCotton, blends, polyester and nylon with matched inkCotton-rich onlyCotton, blends, syntheticsHand-feelFlat, opaqueSoft, sinks into fabricSlight film, raised edgeDurabilityExcellent, 50–100+ washesGood on cotton, 30–50 washesGood, 50–100 washes; can crack on high-stretch zonesSetup costOne screen per colourNone (per-piece pre-treatment)NoneWhere each one failsScreen printing fails on gradients and photographic work: you cannot separate a photo into six spot colours without losing it. It also struggles on high-stretch areas unless the ink system is matched to the fabric.DTG fails on dark polyester and on heavily brushed surfaces, where the ink sits on the nap rather than in the fibre. DTF fails on high-stretch zones and on very textured surfaces, where the film edge lifts.Field exampleA Tokyo label needed a 12-colour photographic back print on 60 pieces. Screen printing would have needed 12 screens and a high setup cost for sixty units. VANRD produced it DTF at 60 pieces, then moved the best-selling design to a four-colour screen print at 600 pieces — same artwork, different economics at different volumes.Numbers that matterScreen printing wins from about 100 pieces in 1–3 colours, and 300+ in four or moreDTG suits 1–50 pieces; DTF stays competitive to roughly 500DTF is the practical route for polyester and blends where DTG strugglesScreen ink is matched to the fibre — plastisol for cotton, low-bleed for polyesterRelated questionsWhat is the best print method for custom graphic hoodies?Does higher GSM always mean better fabric quality?What GSM is best for a premium heavyweight hoodie?What is the difference between French terry and brushed fleece?Fabrics & Techniques: how VANRD sources and tests fabric

Question 22

Consistency comes from a written recipe, a sealed standard and lot control — not from a photo. Record chemical dosage, cycle time, temperature and drying; approve a physical standard under D65; then hold every bulk lot to a Delta E tolerance and keep a retained sample from each lot.

Accepted Answer

Direct answerA repeatable vintage effect is a documented recipe plus a sealed standard. Write down the enzyme or stone dosage, cycle time, temperature, liquor ratio and drying route; approve a physical standard under D65 light; then hold each bulk lot to a stated colour tolerance and retain a swatch from every lot. Without that paper trail, “vintage” drifts between production runs and the reorder stops matching the first drop.Why vintage driftsThree variables move between lots: the base fabric's starting shade (dye lots differ), the machine load and liquor ratio, and the operator's judgement of when to stop. Any one of them changing by a small amount produces a visible difference after washing.The fix is to freeze the variables you can control and measure the one you cannot. Record the base fabric dye lot, fix the machine load, and photograph nothing — measure with a spectrophotometer against the sealed standard.Control pointWhat to recordWhy it mattersBase fabricDye lot and starting shadeWash builds on the base colourRecipeDosage, time, temperature, liquor ratioThe only way to repeat the resultMachine loadkg per drumLoad changes mechanical actionStandardSealed swatch under D65, Delta E toleranceRemoves opinion from approvalRetentionSwatch per bulk lot, kept 12 monthsSettles disputes with evidenceThe commercial upsideConsistency is a reorder mechanism. A brand that can promise “same wash as last season” keeps selling the same style; a brand that cannot ends up re-shooting the collection every drop.It also protects margin: wash rejections are usually discovered after the garment is sewn, so an unstable wash is the most expensive defect to fix.Field exampleA Berlin label's vintage hoodie changed visibly between two production runs, and the second drop photographed cooler than the first. VANRD rebuilt the programme with a written recipe, a sealed D65 standard and a per-lot retained swatch. The next three runs stayed within Delta E 0.8 of the standard.Numbers that matterA sealed physical standard under D65 is the only reliable reference for a washDelta E ≤ 1.0 is a practical tolerance band for garment-washed bulk lotsKeep a retained swatch from every bulk lot for at least 12 monthsMachine load and liquor ratio change the result as much as chemical dosageRelated questionsWhat is the difference between enzyme wash, acid wash, and vintage wash?How can brands keep hoodie fit, fabric weight, and wash effect consistent across reorders?How do you test garment shrinkage after washing?Does higher GSM always mean better fabric quality?Fabrics & Techniques: how VANRD sources and tests fabric

Question 23

Enzyme wash uses cellulase to soften the fabric and remove surface fibres gently. Acid wash uses chlorine-soaked pumice to strip colour unevenly, giving the classic marble look. Vintage wash is a recipe, not a single chemical: a combination of enzyme, stone or bleach steps tuned to a target shade and hand-feel.

Accepted Answer

Direct answerThey are three different processes. Enzyme wash uses cellulase to break down surface fibres — softness and a slight fade, low risk. Acid wash uses chlorine-loaded pumice to strip indigo unevenly, producing the marbled contrast look, and it is the harshest of the three. Vintage wash is not a chemical but a recipe: enzyme plus stone or bleach steps tuned to a specific shade and hand-feel. At VANRD each wash is developed as a recorded recipe with a sealed standard, because “vintage” means nothing without a target swatch.What each process does to the garmentEnzyme washing is a controlled bio-polishing step. It improves hand-feel and reduces pilling, with a small, even colour loss. It is the safest route for softness and the usual base for a vintage look.Acid washing is a chemical and mechanical process: pumice stones carry chlorine onto the garment, stripping colour in patches. The result is high contrast and unmistakeable, but the fabric loses strength and the process needs careful neutralisation — an unrinsed garment will keep fading in the bag.Vintage washing combines steps: enzyme for hand, stone for abrasion, and a measured bleach or tint step for shade. It is tuned by trial, which is why it needs a sealed standard approved under proper lighting.ProcessMain effectRisk / control pointEnzyme washSoft hand, light even fadeLow risk; check residual strengthAcid washHigh-contrast marble fadeChlorine neutralisation, fabric strengthVintage washTuned shade plus abrasionRecipe drift between lots; needs sealed standardStone washMechanical abrasionMachine wear, dust, pumice residueBleach washShade liftOver-bleaching, patchy resultApproving a wash correctlyApprove under D65 light and on the final fabric, not on a flat sketch or a screen photo. Keep a sealed bulk standard and a written recipe with chemical dosage, cycle time, temperature and drying route.One production detail worth specifying: wash lots vary. Approve a tolerance band (for example Delta E ≤ 1.0) rather than a single swatch, and state how many shades are acceptable across the run.Field exampleA Seoul label asked for a “90s vintage” hoodie and approved a photo. VANRD produced three physical variants — enzyme only, enzyme plus stone, and enzyme plus a light bleach step — and the brand chose the second. Because the recipe was written down with a sealed standard, the reorder landed within tolerance on the first bulk lot.Numbers that matterEnzyme wash is the lowest-risk route for softness and pilling controlAcid wash requires chlorine neutralisation and reduces fabric strengthVintage must be approved on a sealed physical standard, never a photoSet a shade tolerance band such as Delta E ≤ 1.0 across bulk lotsRelated questionsWhat happens if the delivered bulk order does not match the approved sample?How should brands approve denim wash effects before bulk production?Does higher GSM always mean better fabric quality?What GSM is best for a premium heavyweight hoodie?Fabrics & Techniques: how VANRD sources and tests fabric

Question 24

Control shrinkage at three points: buy compacted or pre-shrunk fabric, measure the actual shrinkage on a wash test, and build the allowance into the pattern. Untreated cotton knit typically shrinks 3–5% in length; compacted cotton with a controlled wash cycle lands around 1–3%.

Accepted Answer

Direct answerShrinkage is reduced in three places, not one. Buy fabric that has been compacted or pre-shrunk, measure the real shrinkage with a wash test on the actual bulk fabric, and build the allowance into the pattern and grade. Untreated cotton knit can lose 3–5% in length on the first wash; compacted cotton with a controlled finishing route typically holds to 1–3%. At VANRD the wash test is run before bulk approval, and the size set is measured again after it.Where the shrinkage actually comes fromCotton knit is held under tension through knitting, dyeing and finishing. When the garment is washed, that tension releases and the loops relax — mostly in length, less in width. The amount depends on yarn twist, loop length, and whether the mill compacted the fabric before cutting.Garment washing adds a second, deliberate shrinkage step. That is why garment-dyed and washed styles should be cut with a larger allowance than piece-dyed styles.Fabric routeTypical length shrinkageWhat to doUntreated cotton knit3–5%Pre-shrink, or add allowanceCompacted cotton knit1–3%Measure and allowGarment washed / dyed2–5% on topCut after wash trialsCotton-poly blend1–2%Still verify, do not assumeThe test that settles argumentsCut a 50 × 50 cm square from the bulk fabric, mark a 40 cm reference in both directions, wash at the temperature the care label will state, dry the way the customer will dry, then measure again.

Question 25

Drape is weight and structure working against gravity. A 450 GSM loopback holds a boxy, off-body silhouette; a 280 GSM terry collapses into a soft, close drape. If the design brief is oversized and structured, the fabric must be heavy enough to stand off the body, and the pattern must be cut to the shrinkage the fabric will actually show after washing.

Accepted Answer

Direct answerFabric decides whether an oversized garment reads as structured or slouchy. A 450 GSM loopback keeps a boxy, off-body line; a 280 GSM terry falls close to the body and loses the shoulder. For a structured oversized brief, specify 400–500 GSM French terry or double-face, cut the pattern for the measured shrinkage, and lock the fabric before grading — changing fabric after fit approval is what turns an oversized garment into a merely large one.Weight, structure and the shoulder lineA knit's drape comes from three things: mass per square metre, loop structure and the finishing route. Heavier loopback stands away from the body; brushed fleece is softer and drapes closer even at the same weight. A compacted finish adds stability; a garment wash relaxes the fabric and softens the line.The practical consequence: if the reference photo shows a shoulder that stands out horizontally, the fabric is almost certainly 400 GSM or above. Trying to reach that silhouette on 300 GSM requires interfacing and structure panels, which changes the hand-feel entirely.FabricTypical weightResult on an oversized blockLight loopback280–320 GSMSoft drape, sits close, shoulder dropsMid French terry340–380 GSMBalanced, some structure, holds shapeHeavy loopback400–500 GSMBoxy, off-body, crisp shoulder lineBrushed fleece380–450 GSMWarm and plush, softer silhouetteDouble-face / bonded500 GSM+Structural, almost outerwearCut for the shrinkage, not for the sampleAn oversized pattern is unforgiving about shrinkage. If the fabric shrinks 4% in length and the pattern was cut to the finished measurement, an 72 cm body becomes 69 cm after the first wash — and the drop shoulder moves up at the same time.The fix is procedural: measure shrinkage on the actual bulk fabric, add the allowance into the pattern, and re-check the size set after one wash cycle. At VANRD the size set is measured again after wash before bulk approval for exactly this reason.Field exampleA Los Angeles label wanted a boxy 68 cm body with a strong horizontal shoulder. Their first sample was built on 320 GSM terry and collapsed at the shoulder. VANRD rebuilt the block on 430 GSM loopback, added 3% length allowance for measured shrinkage, and the approved sample held its line after the wash test.Numbers that matter400–500 GSM is the working range for a structured oversized hoodieA 4% length shrinkage on a 72 cm body is roughly 3 cm lost after washingRe-measure the size set after one wash before bulk approvalChanging fabric after fit approval invalidates both the fit and the gradeRelated questionsDoes higher GSM always mean better fabric quality?What GSM is best for a premium heavyweight hoodie?What is the difference between French terry and brushed fleece?Is 100% cotton or a cotton-polyester blend better for hoodies?Fabrics & Techniques: how VANRD sources and tests fabric

Question 26

Yes. A factory can usually match a swatch through stock fabric, an existing mill quality, or a custom knit and dye run. What changes is lead time, minimum quantity and whether the colour is a lab dip or a bulk dye lot. Ask for the mill quality reference, a lab dip under D65 light, and a written GSM and composition spec before sampling.

Accepted Answer

Direct answerYes — most factories can source against a physical swatch. There are three routes: stock fabric already in the mill's range (fastest, cheapest), an existing mill quality re-dyed to your shade (needs a lab dip and a dye-lot minimum), or a custom knit and dye run when the construction itself is unusual. At VANRD we quote the route before sampling, because the route decides both the MOQ and whether your colour can be repeated exactly on the reorder.The three sourcing routes and what they cost youA swatch is a physical claim: weight, composition, knit structure and shade. The factory's job is to find the closest construction first, then match the shade second — doing it in the other order is how brands end up with the right colour on the wrong hand-feel.Stock fabric is the fastest route but the shade range is fixed. Re-dyeing an existing quality gives you the colour you want at the cost of a dye-lot minimum per colour. A custom knit is only justified when the construction is genuinely new to the mill.RouteTypical lead timeWhat it needs from youStock fabric3–7 days to swatchAccept one of the mill's shadesExisting quality, re-dyed10–20 days incl. lab dipPantone or physical shade, dye-lot quantityCustom knit and dye25–45 daysConstruction spec, GSM tolerance, volume commitmentWhat to demand before you approveAsk for the mill quality code, a lab dip approved under D65 lighting (not office lighting), and a spec sheet stating GSM with a ±5% tolerance, composition and shrinkage. Then keep a sealed bulk swatch from each dye lot.This matters at reorder stage: a re-dye that lands half a shade off is the most common reason a second run sells worse than the first.Field exampleA Dutch brand sent VANRD a 380 GSM loopback swatch in a washed sage green. The construction matched an existing mill quality, so the route was re-dye rather than custom knit. Lab dip was approved in nine days, the dye-lot minimum was 300 kg, and the bulk shade stayed inside a Delta E of 1.0 against the approved dip across two reorders.Numbers that matterLab dip approval typically takes 7–10 days including shippingA ±5% GSM tolerance is normal; hold the mill to a written spec sheetSealed bulk swatch per dye lot is what protects you at reorderCustom knit and dye is only justified when the construction is new to the millRelated questionsHow does fabric choice affect the drape and oversized fit of a garment?Can the manufacturer help source fabrics, trims, and accessories?Does higher GSM always mean better fabric quality?What GSM is best for a premium heavyweight hoodie?Fabrics & Techniques: how VANRD sources and tests fabric

Question 27

100% cotton gives better hand-feel, cleaner dye depth and stronger premium positioning, but shrinks more and costs more. An 80/20 cotton-poly fleece holds shape after washing, resists shrinkage and is more forgiving at volume — the right call for repeatable programmes and tighter target costs.

Accepted Answer

Direct answerNeither is better in the abstract. 100% cotton delivers the hand-feel, dye depth and “premium” language most streetwear brands sell — at a higher cost and roughly 3–5% shrinkage unless it is pre-shrunk. An 80/20 cotton-polyester fleece shrinks less, keeps its shape through washing, resists pilling and hits a lower unit price — which is why it dominates volume hoodie programmes. At VANRD we quote both for every hoodie brief so the cost and shrinkage trade-off is visible before sampling.What each fibre actually doesCotton is a natural staple fibre: it dyes deep, feels dry rather than slick, and takes garment washing and distressing predictably. Its weakness is dimensional stability — loops relax in hot water unless the fabric is compacted or pre-shrunk.Polyester is a filament: it does not shrink the way cotton does, adds tensile strength and gives the fleece a springier recovery. Blended at 20%, it keeps most of the cotton hand-feel while stabilising the garment. Push the polyester share much higher and the face starts to read synthetic under light.100% cotton80/20 cotton-polyHand-feelDry, natural, premiumSlightly slicker, springierShrinkage3–5% unless pre-shrunkAround 1–2%PillingLow to moderateLowerDye depthDeep, garment wash friendlySlightly flatter in dark shadesUnit costHigherLowerBest forPremium positioning, garment dyeVolume programmes, repeat reordersHow to decide on one briefStart from the promise on the hangtag. If the brand sells “heavyweight 100% cotton, garment dyed”, the fabric must support that claim and the price has to carry it. If the brand sells fit, graphic and drop cadence, an 80/20 fleece protects margin and removes shrinkage complaints.One caveat worth writing into the spec: if you intend to garment dye, polyester resists the dye and produces a muted, heathered result. In that case stay on cotton.Field exampleA Canadian label launched a 100% cotton 430 GSM hoodie for a premium drop and an 80/20 version of the same block for their core range. Nine months later the cotton piece had the better reviews and the blend piece had the better reorder rate — same fit, same pattern record, two different price points doing two different jobs.Numbers that matter100% cotton shrinkage: roughly 3–5% without pre-shrinking80/20 blend shrinkage: roughly 1–2%, shape retention noticeably betterPolyester above about 35% starts to read synthetic in photos and in handGarment dyeing requires a cotton-dominant base to take colour evenlyRelated questionsDoes higher GSM always mean better fabric quality?What is the difference between French terry and brushed fleece?What GSM is best for a premium heavyweight hoodie?Can a manufacturer source fabric from a reference sample or swatch?Fabrics & Techniques: how VANRD sources and tests fabric

Question 28

Both are knitted cotton loops. French terry leaves the inside loops uncut, so it breathes, holds a boxy shape and prints crisply. Brushed fleece is the same base with the inside sanded into a nap, so it feels warmer and softer immediately but pills sooner and relaxes over time.

Accepted Answer

Direct answerFrench terry and brushed fleece are cousins, not opposites. French terry keeps the inside loops intact: breathable, structured, better print surface, lower pilling. Brushed fleece is French terry that has been sanded on the inside to raise a nap: warmer and softer at the same weight, but the brushed fibres pill and the garment relaxes with wear. On VANRD hoodie programmes, structured streetwear usually lands on 400+ GSM French terry; cosy winter product lands on 380–450 GSM brushed fleece.Construction, not brandingA knit is a field of loops. On French terry those loops stay closed on the inside, which traps air without blocking moisture movement — warm enough for autumn, wearable in spring. On brushed fleece the same fabric passes through a brushing machine that breaks the loops into cut fibres, so the surface traps far more air and feels plush on first touch.The trade is durability. Cut fibres migrate, so the brushed face pills and flattens sooner than an intact loop. That is a property of the construction, not a defect in the mill.French terryBrushed fleeceInside faceUncut loopsBrushed napWarmth at equal GSMModerateHigherStructure / drapeHolds boxy shapeSofter, relaxesPrint surfaceSmooth, crisp edgesSlightly fuzzy edgesPillingLowModerate on the insideTypical range280–500 GSM260–580 GSMChoosing for a real programmeIf the hoodie has to photograph structured and hold its silhouette drop after drop, choose French terry. If the selling point is warmth and a soft hand-feel — winter markets, loungewear, gifting — brushed fleece earns its place.Decoration matters too. DTG and fine screen work sit better on a flat terry face; embroidery behaves identically on both. For print-heavy ranges, terry is the safer base.Field exampleFor a Copenhagen label running an oversized drop, we moved the core hoodie from brushed fleece to 420 GSM French terry. The garment kept its boxy shape after ten wash cycles in our shrinkage test, and the front chest print registered 1 mm tighter because the face was flat. Their winter piece stayed on brushed fleece at 400 GSM for warmth.Numbers that matterFrench terry: 280–500 GSM typical, shrinkage around 1–3%Brushed fleece: 260–580 GSM typical, shrinkage around 2–4%Brushed face is the pilling surface — expect gradual flattening after repeated washingBoth accept embroidery equally well; terry takes fine print detail betterRelated questionsDoes higher GSM always mean better fabric quality?What GSM is best for a premium heavyweight hoodie?Is 100% cotton or a cotton-polyester blend better for hoodies?Can a manufacturer source fabric from a reference sample or swatch?Fabrics & Techniques: how VANRD sources and tests fabric

Question 29

For a premium heavyweight hoodie, 400–450 GSM brushed fleece or 400+ GSM French terry is the sweet spot: heavy enough to feel substantial in the hand, still wearable and printable. Below 380 GSM reads as standard weight; above 500 GSM seams bulk up, drying time and freight cost climb, and construction faults become visible.

Accepted Answer

Direct answerFor a premium heavyweight hoodie, target 400–450 GSM in brushed fleece, or 400+ GSM in French terry if you want structure without heat. 320–380 GSM is the volume standard rather than a premium weight, and above roughly 500 GSM you are building outerwear with a hood, not a hoodie. At VANRD we develop these weights as a single recorded specification, so the first run and the reorder feel the same.What the number actually measuresGSM is grams per square metre — mass, not quality. A loosely knitted 400 GSM fleece made from short-staple cotton pills faster and feels worse than a well-built 320 GSM made from combed yarn. Weight tells you drape, warmth and structure; yarn quality and knitting density tell you how it will survive twenty washes.That is why two 420 GSM hoodies can feel completely different on the same day: one is a double-face with tight tension, the other a slack single knit with a heavy brushed back.WeightWhat it is used forWhat the buyer feels280–320 GSMLight hoodies, layering piecesSoft, drapes close, not premium320–380 GSMThe volume standard, year-round coreSubstantial, holds print and shape400–450 GSMPremium streetwear drops, winter programmesStructured shoulders, obvious heft450–500 GSMFlagship piecesStands off the body, boxy by default550 GSM+Specialty or bonded constructionsSeams bulk, cuffs recover slowly, slow to dryWhere premium actually breaks downPast about 500 GSM the sewing window narrows: needle and feed-dog settings must change, seam bulk appears at the armhole and hood join, and any pattern error that a 350 GSM fabric hides becomes a visible pucker. Heavier fabric also means more grams of cotton per garment, so unit cost climbs with weight before you add a single print.A practical check: ask for the fabric spec sheet (GSM, composition, knit type), then weigh a one-square-metre cut from the sample. A ±5% variance is normal; a 30 GSM drop at bulk stage is substitution, not tolerance.Field exampleA Berlin streetwear label came to VANRD with a 480 GSM brushed fleece reference that kept arriving lighter at bulk with their previous supplier. We rebuilt the programme on a 430 GSM brushed-back loopback with a documented fabric record, weighed every sample and bulk roll, and held the variance inside 5%. The drop shipped on a 25–35 day bulk window and the reorder ran off the same record with no re-approval.Numbers that matter400–450 GSM is the range VANRD recommends for a first premium heavyweight hoodie320–380 GSM covers most volume programmes and prints more cleanly±5% GSM variance is the accepted production tolerance; verify with a weighed swatchAbove 500 GSM, expect longer dry time, higher freight weight and tighter sewing controlRelated questionsIs 100% cotton or a cotton-polyester blend better for hoodies?How can I reduce pilling and fabric wear after washing?Can a manufacturer source fabric from a reference sample or swatch?How does fabric choice affect the drape and oversized fit of a garment?Custom hoodie manufacturing at VANRD

Question 30

No. GSM measures mass per square metre, not yarn quality, knitting density or finishing. A well-built 320 GSM combed-cotton terry outperforms a slack 400 GSM fleece on pilling, shape retention and hand-feel. Weight is a design decision; quality comes from fibre, yarn count, tension and finishing.

Accepted Answer

Direct answerNo — GSM measures weight, not quality. A tightly knitted 320 GSM fleece from combed, long-staple yarn will pill less, hold its shape longer and feel better than a loosely built 400 GSM made from short-staple cotton. Weight is a design decision about drape and warmth; quality is decided by fibre length, yarn count, knitting tension, dyeing and finishing. At VANRD we specify all five on the fabric record, because the GSM number alone cannot protect a brand from substitution.What the number cannot tell youTwo fabrics at 420 GSM can differ by 40% in cost and by years in service life. The difference sits in things the GSM label does not carry: whether the yarn is carded or combed, the loop length, the machine gauge, the tension, and whether the fabric was compacted after dyeing.This is why “looks heavy” is a weak buying criterion. A slack knit feels thick in the hand but collapses at the seam and pills at the cuff within a season.SignalWhat it tells youWhat it hidesGSMMass, warmth potential, drapeYarn quality, density, finishingCombed vs cardedFibre length, pilling resistanceKnitting tensionKnit gaugeSurface density and stabilityDye lot consistencyShrinkage test resultDimensional stabilityColour fastnessPilling gradeSurface durabilitySeam strengthA practical verification routineAsk for the fabric spec sheet, then verify three things independently: weigh a one-square-metre cut (±5% is normal), run a wash-and-measure shrinkage test, and check a pilling grade after abrasion. If a supplier cannot provide a spec sheet, the GSM claim is marketing.For orders above roughly USD 5,000, a third-party lab test for composition and weight costs little relative to the risk of a substituted fabric arriving at bulk.Field exampleA buyer sent VANRD a 380 GSM reference that pilled badly after five washes. We rebuilt it at the same 380 GSM but on combed cotton with a tighter gauge and a compacted finish. The garment came back visually identical in weight, and the pilling grade improved from 2–3 to 4 on the same abrasion test.Numbers that matter±5% GSM variance is normal production tolerance; anything beyond that is substitutionPilling is graded on a 1–5 scale — grade 4 and above is a durable knit surfaceA one-square-metre swatch on a digital scale is the cheapest verification availableThird-party lab tests for weight and composition typically cost USD 30–80Related questionsWhat is the difference between French terry and brushed fleece?What GSM is best for a premium heavyweight hoodie?Is 100% cotton or a cotton-polyester blend better for hoodies?Can a manufacturer source fabric from a reference sample or swatch?Fabrics & Techniques: how VANRD sources and tests fabric
