Jorlynn Quality Management System

When it comes to quality, we know what’s at stake for your brand. That’s why our control system covers supplier audits, incoming checks (IQC), in-process inspection, OQC, and a final full inspection before shipping.

Each seamless or cut & sew garment goes through five strict quality checks—so what arrives in your hands meets the standards your customers expect.

And if anything goes wrong, we own it. Our team will act fast to resolve any production issue—because your brand reputation is our responsibility too.

Knitting

Knitting begins only after the pre-production sample is fully approved. Before production, we conduct:

① Raw material and yarn threading confirmation;

② Verification of technical specifications and measurements;

③ Inspection of fabric surface and texture quality.

Throughout knitting, our quality inspector monitors output every 2 hours to ensure consistency, accuracy, and fabric integrity from start to finish.

Dyeing

Dyeing brings vibrant color to each garment, and we follow strict standardized procedures:

① Confirm the sample shade matches the approved dye color precisely;

② Control water temperature and dyeing time accurately for each batch;

③ Evaluate fabric performance—handfeel, stretch recovery, and shrinkage stability.

We also ensure compliance with your market’s regulations, including tests for formaldehyde, azo dyes, and other chemical safety standards, guaranteeing full product qualification.

Cutting

Cutting requires high accuracy to ensure fit and production efficiency.

For styles with computer-programmed patterns, fabric is cut precisely along the designated lines with no residual marks.

For non-digital designs, we follow physical templates strictly to maintain consistency.

When garments include accessories, our team carefully checks color matching between main panels and accessory pieces to ensure visual harmony.

Sewing

  • Ensure all trims match the specified color listed in the process sheet.
  • Adjust stitch spacing to follow the approved sample and process standards—typically 18 to 21 stitches per 3cm.
  • Stitch lines must remain straight, even, and flat, without issues like twisting, puckering, or overlapping seams.
  • Labels must be accurately centered, with aligned top and bottom edges for a clean and consistent finish.

Ironing

  • Perform an initial inspection to ensure the garment matches the specifications in the production sheet. Any discrepancies must be confirmed and reported immediately.
  • Proceed with ironing, ensuring the garment is symmetrical and properly sized according to the process sheet.
  • Verify that the collars are symmetrical, free of blistering or wrinkling at the neckline.
  • Confirm that both sleeves and pant legs are of equal length, and that the cuffs and leg openings are consistent in size.

Packaging

Packaging is more than simply placing seamless or cut & sew activewear into bags or boxes. At this stage, our team conducts a final quality check for both product types. Any defective garments are carefully removed and sent back for further inspection and correction, ensuring that only products meeting our strict standards are shipped to our clients.

    Color Control

    We use a lightbox and spectrometer to ensure color consistency for each and every production batch.

    By doing so, we test and avoid any color deviation, making sure your bulk goods are in correct color as per your design and requirement.

    Chemical Control

    Authorities and consumers across the globe have become quite sensitive in recent years to product safety and health-related issues associated with chemicals and substances used in products sold in their markets.

    Our testing will not stop until the volume of formaldehyde is qualified as per national standards.

    Color Fastness Test

    We aim at creating a second skin for all customers, so color fading will definitely lead to annoyances.

    In TWINALL, all clothing should stand the color fastness test. We conduct the test by cutting out a piece of fabric, then we put it in a beaker with 5g washing powder dissolved in warm water at 60 ℃.
