Step-by-Step: Vanrd's 8-Step QC Workflow

Step 1 – Fabric inspection on inspection machine

We inspect incoming fabric rolls on inspection machines under proper lighting.
QC checks for:
    Stains, oil marks, dirt and dust
    Snags, pulled yarns, holes and thick/thin places
    Colour shading between rolls and within rolls
    Width and weight consistency
Defective sections are marked and recorded so they are not placed into production.

Step 2 – Fabric wash & shrinkage tests

Before bulk cutting we run wash and shrinkage tests on each main fabric.
Typical checks include:
Dimensional change after recommended wash
Handfeel and surface change
Basic colourfastness to washing
Shrinkage data is shared with pattern and marker teams so production patterns are adjusted to keep your final fit on-spec.

Step 3 – Print & embroidery inspection

All printing, embroidery and appliqué passes a dedicated check point:
Artwork size and placement against tech pack
Colour accuracy versus approved strike-offs
Stitch density and coverage on embroidery
No missing stitches, loose threads, ghosting or cracking
Only approved panels move to sewing.

Step 4 – In-line sewing process checks

During sewing, line QC performs in-line inspections by operation:
Seam type and stitch length
SPI and tension balance
Matching of panels, pocket positions and plackets
Correct trims and thread colours
Defective pieces are sent to repair, and recurring issues trigger immediate feedback to line leaders.

Step 5 – End-of-line pre-check

After thread-trimming, ironing and basic finishing, we run an end-of-line pre-check by bundle:
Overall appearance and measurements on sample pieces
Zips, snaps and buttons functioning correctly
Clean garments with no stains or marks
Only bundles that pass this gate move to 100% QC.

Step 6 – 100% QC by dedicated QC team

A dedicated QC group performs 100% piece-by-piece inspection against our checklist and your spec.
They confirm:
Size and measurements within tolerances
Construction and seams without major or critical defects
Branding, labels and hangtags correctly applied
Garments are separated into pass, rework and reject categories, with records kept for every batch.

Step 7 – Pre-packing supervisor audit

Before packing, a line or department supervisor runs an additional audit:
Random re-check of QC-passed pieces
Confirmation that corrections have been implemented
Visual review of finishing quality by size and colour
This second layer helps keep QC standards consistent between shifts and styles.

Step 8 – Packing & carton checks

At packing, our team verifies counts and labels so cartons arrive ready for your DC:
Piece count per polybag and per carton
Size ratios and colour breakdown per your packing list
Barcode, size stickers and carton marks
Only after QC signs off on the packing checklist are cartons sealed and moved to the warehouse.

FAQs — Custom Clothing Manufacturing

  • What should brands confirm before repeating a jacket order?
    Before repeating a jacket order, brands should confirm whether the same fabric, lining, rib, zipper, snap buttons, labels, patches, packaging materials, and color references are still available.

    Even repeat orders can show differences if the fabric batch, dye lot, rib quality, zipper supplier, or hardware finish changes. Mature brands should keep an approved production record that includes fabric swatches, trim cards, color references, measurement specs, logo placement, label position, packaging standards, and previous approved samples.
  • How do you control logo and patch placement in custom jacket production?
    Brands can control logo and patch placement by preparing a detailed placement map before sampling. Jacket styles such as racing jackets, varsity jackets, bomber jackets, and work jackets may include multiple patches, sleeve graphics, embroidery, appliques, pocket labels, and panel details.

    Before bulk production, brands should confirm patch size, position, material, thread color, edge finish, artwork file, and tolerance standards. VANRD compares bulk production against the approved sample and placement standard to check symmetry, spacing, alignment, and consistency across sizes.
  • What should brands prepare before requesting a performance tracksuit quote?
    Before requesting a performance tracksuit quote, brands should prepare the key details that affect sampling, cost, and production planning. These include the tracksuit type, jacket and pants construction, tech pack or reference images, fabric direction, logo technique, colorways, size range, estimated quantity, destination country, timeline, and packaging requirements.

    If the brand does not have a complete tech pack, reference images can still help the manufacturer understand fit, silhouette, zipper style, pocket structure, waistband design, cuff details, and branding placement.

    For a faster and more accurate quote, brands should also explain the product use case. A tracksuit for team warm-up, gym training, travel, athleisure, or streetwear collection may require different fabrics, trims, construction standards, and quality control points.
  • Which logo techniques work best for performance tracksuits?
    The best logo technique for performance tracksuits depends on fabric type, stretch level, washing requirements, logo size, placement, and brand positioning. Common options include screen printing, heat transfer, reflective printing, embroidery, woven patches, rubber patches, zipper pullers, woven labels, care labels, hangtags, and packaging details.

    For high-stretch or lightweight performance fabrics, brands should be careful with heavy embroidery or thick patches because they may affect comfort, drape, or movement. Heat transfer and lightweight printing can work well for clean performance branding, while embroidery or patches may be better for premium streetwear-style tracksuits.

    Before sampling, brands should confirm artwork files, logo size, Pantone color, placement, washing requirements, and whether the tracksuit needs private label packaging. This helps avoid logo cracking, peeling, color mismatch, or placement inconsistency in bulk production.
  • How can brands keep tracksuit samples and bulk production consistent?
    Brands can keep tracksuit samples and bulk production consistent by approving clear production standards before bulk cutting starts. Important references include fabric swatches, trim cards, measurement specs, logo placement maps, approved artwork files, color standards, and the final pre-production sample.

    Performance tracksuits need extra attention because small changes in fabric stretch, zipper quality, waistband elasticity, cuff construction, lining, or seam tension can affect fit and movement. Both jacket and pants must also match in fabric handfeel, shade, trims, and overall finishing.

    Before bulk production, brands should confirm tolerance rules for measurements, logo position, color difference, seam quality, zipper function, waistband recovery, pocket placement, and packing. This reduces risk and helps the manufacturer check bulk goods against the approved sample.
  • What is the MOQ for custom performance tracksuit production?
    The MOQ for custom performance tracksuit production depends on fabric availability, color, logo technique, trim sourcing, size range, and production complexity. For VANRD custom programs, MOQ usually starts from 100+ pieces per color and style.

    If a brand uses available fabrics and simple branding, the development plan may be more flexible. If the tracksuit requires custom dyed fabric, special zippers, reflective details, multiple logo placements, private label packaging, or a complex size range, the practical MOQ may be higher.

    Before quoting, brands should confirm whether they need a full tracksuit set, jacket only, pants only, or multiple colorways. This helps the manufacturer calculate fabric usage, cutting efficiency, production cost, and sampling requirements more accurately.
