Product Overview
Nylon 66 FDY Yarn for High-Performance Zippers & Industrial Webbing
Nylon 66 FDY Yarn is designed for uses where abrasion resistance, high modulus, and dimensional stability are essential. Its fully drawn structure offers a more stable yarn performance under continuous stress than traditional nylon yarns, making it appropriate for industrial webbing, high-end zipper manufacture, and other load-bearing textile applications.
The yarn can be utilised by manufacturers of metal zippers as a monofilament wrapping yarn to assist create a sturdy and durable textile structure around the metal components. Its low elongation and high modulus aid heavy-duty webbing makers in preventing excessive extension when the webbing is pulled continuously.
