Polyester plus stretch yarn is an ideal raw material for knitting or weaving processing. It is a type of textured yarn for polyester chemical fiber. In addition to the general polyester breaking strength and modulus of elasticity, excellent heat setting, good resilience, heat resistance, In addition to the characteristics of light resistance, strong corrosion resistance, easy washing and quick drying, it also has the characteristics of high bulkiness, good heat insulation, comfortable feel, soft gloss and so on. Polyester low-elastic yarn uses polyester chips as raw materials, high-speed spinning polyester pre-oriented yarn, and then through drawing false twist processing, suitable for the production of clothing fabrics, bedding and decorative items. Polyester low-elastic yarn with high crimp shrinkage ratio is relatively bulky, and the fabric is rich. It can be adjusted by the elastic process. The process selection is low. The residual elongation is better. The dyeing is better, the strength is higher, the crimp rate is higher, and the wool In the case of silk, a lower residual elongation will be selected, while an excessively high residual elongation will produce polyester low-elastic stiff yarns, the shrinkage rate will be reduced, and the dyeing and finishing of the fabric will not be easy to set, wrinkling and other adverse effects.
