False Twist Texturing of Nylon Yarns
topic
Nylon 6 and nylon 6.6 false twist texturing uses lower heater temperatures of 160 to 195 degrees Celsius than polyester from the lower glass transition and melting temperatures of polyamide polymers, with nylon's higher moisture regain and lower processing tension compared to polyester requiring adapted disc configurations and heater temperature profiles to achieve the crimp stability and bulk development required for hosiery, underwear, and swimwear nylon textured yarn applications.
Role
Produces the textured nylon yarns used in fine hosiery, lingerie, and swimwear through false twist texturing processes adapted for polyamide thermal characteristics that differ substantially from polyester processing conditions, with nylon texturing process optimisation being important for achieving the high bulk, soft handle, and consistent dyeability required for premium hosiery and intimate apparel yarn quality.
