Nylon Zipper: Nylon Zipper (尼龙拉链)
A zipper made from a continuous nylon monofilament coil sewn onto the tape edge. The spiral teeth are flexible, lightweight and available in many colours, making nylon zippers popular for apparel, bags and home textiles. They are softer than metal or moulded resin types and resist corrosion. Quality depends on monofilament strength, coil pitch and stitch density, which together control pull strength and cycle life.
