The Manufacturing Process of Nylon Zippers: From Resin to Coil
Published Time:
2025-11-10
Nylon zipper production begins with melting polyamide resin pellets, which are extruded into thin monofilaments. These filaments are then woven into continuous coils, which form the zipper teeth. The coils are heat-set to maintain their shape before being stitched onto polyester or cotton fabric tapes. The slider, typically made of plastic, is attached to complete the zipper. This automated process allows for high-volume production, keeping costs low while ensuring consistent quality. Innovations like invisible nylon zippers, where the teeth are hidden behind the tape, showcase the adaptability of this manufacturing technique to meet diverse design needs.
