Brief introduction of polyester high elastic yarn (nylon like)
1. Polyester high elastic yarn: it is a kind of fabric made of textured fiber. The chemical fiber filament is made into spiral loop shape after one heating deformation, which has high elastic expansion rate. It is called high elastic filament, and the product is called high elastic fabric. Such as nylon or polypropylene elastic pants, elastic socks, elastic swimming suit, etc.
2. Polyester high elastic yarn: the product has good elasticity, good handle, stable quality, strong tensile force, uniform dyeing, bright color and complete specifications. The product can be pure woven, or interwoven with silk, cotton, viscose and other fibers, and can be made into elastic fabrics and various kinds of wrinkled fabrics. The fabrics made have a unique style.
