Standards for Evaluating Zipper Performance in Sportswear
Author:
Every zipper undergoes detailed inspection to ensure both function and form meet quality expectations. Particular attention is given to the pull-tab assembly, where the cord end must be neatly finished with a secure, symmetrical knot. Loose threads or irregular trimming at this junction are not acceptable.

Zippers are tested for smooth operation through multiple open-close cycles, verifying the slider moves effortlessly without catching. The tape must lie flat against the fabric with straight, consistent stitching along both sides. Any twisting, puckering, or misalignment results in rejection.
These meticulous checks guarantee that zippers not only perform reliably during athletic activity but also maintain a clean, professional appearance that reflects the brand's attention to detail.
Note: Water-resistant zippers receive additional sealing verification.
