Quality control
Checked at four points, not at the end.
Incoming yarn, coating weight, finished roll and packed carton are each inspected before the next step starts. Buyers who need documented values get the test report for the construction they ordered.
- Incoming material — yarn count and mesh fabric weight against the approved reference.
- Coating — sizing and adhesive pick-up checked against the agreed finished weight.
- Finished roll — width, length, weight, winding tightness and roll diameter.
- Packing — label, shrink wrap, carton count and loading plan verified before the container is closed.
