How Do Factories Prevent Zipper Waviness on Stretch Fabrics?

Prevent zipper waves through compatible stabilization, feeding, and dimensional control.

Closures and edge details need compatible materials, stable attachment, and controlled dimensions. Check operation, symmetry, skin comfort, and dimensional change after care; small differences in feed tension or stabilization can create visible distortion even when the individual component meets its own purchasing specification. Inspect after laundering as well as sewing.
