Description

technical field

[0001] The application belongs to the technical field of fiber preparation, and in particular relates to a polyester low elastic yarn and a preparation method thereof. Background technique

[0002] Polyester low elastic yarn (Draw texturing yarn, referred to as DTY) is a kind of textured yarn type of polyester chemical fiber. It is processed by false twisting and has the characteristics of short process, high efficiency and good quality. In addition to general polyester, it has excellent heat-setting properties, good resilience, heat resistance, light resistance, strong corrosion resistance, easy washing and quick drying, etc. In addition to its characteristics, it also has the characteristics of high bulkiness, good heat insulation, comfortable hand feeling and soft luster. It is an excellent silk for fabric fabrics.

[0003] However, the polyester low-elasticity yarn prepared by the current method has the characteristics of high elastic modulus and good re...
