Polyester High Stretch Yarn
1. The elastic force is different: the elasticity of the high-elastic yarn is higher than that of the low-elastic yarn; The most obvious difference in physical properties is that the curling shrinkage rate of high-elastic filament is larger;
2. Different processes: the difference between low-elastic wire and high-elastic wire is that when texturing, whether the second hot box of the texturing machine is opened, the opening is low-elastic wire, and if it is not opened, it is high-elastic wire;
3. The stability is different: because the high-elastic filament has not been shaped by the second hot box, the stability of the crimping is not as good as that of the low-elastic filament.
Application fields of high-elastic yarn:
1. Mainly used in knitting, hosiery, clothing, cloth, ribbing, fabrics, textiles, woolen fabrics, sewing threads, embroidery, ribs, webbing, medical bandages, etc.;
