Abstract

The invention relates to a manufacturing method of special-shaped hollow warmth keeping polyester drawn textured yarn. Special-shaped warmth keeping polyester fibers are adopted as raw materials, a DTY elasticity enhancing method is adopted, and the needed special-shaped hollow warmth keeping polyester drawn textured yarn is prepared through a pre-interlaced nozzle, a first roller, a deformation heat box, a cooling plate, a false twister, a second roller, a main interlace nozzle, an auxiliary second roller, a sizing heat box, a third roller and an oiling wheel in a winding formation mode. The special-shaped hollow warmth keeping polyester drawn textured yarn has excellent three-dimensional curling performance and warmth keeping performance; the special-shaped hollow warmth keeping polyester drawn textured yarn is widely applied to home textiles, especially underwear, the elasticity of the polyester drawn textured yarn is between the elasticity of spandex and the elasticity of nylon, and the special-shaped hollow warmth keeping polyester drawn textured yarn can have excellent warmth keeping performance on the basis of keeping excellent elasticity; the special-shaped hollow warmth keeping polyester drawn textured yarn can have an excellent healthcare function through far infrared and anion emitting functional particles added into the fibers, has a coordinated warmth keeping effect and has very excellent use prospects in high-end underwear and decorative fabric.

Description

technical field [0001] The invention relates to the technical field of textile production, in particular to a method for manufacturing special-shaped hollow heat-retaining polyester low elastic yarn. Background technique [0002] Draw texturing yarn (DTY for short) is a textured yarn type of polyester chemical fiber. It uses polyester chip (PET) as raw material, spins polyester pre-oriented yarn (POY) at high speed, and then draws False twist processing. It has the characteristics of short process, high efficiency and good quality. In addition to the characteristics of general polyester high breaking strength and elastic modulus, excellent heat setting, good resilience, heat resistance, light resistance, strong corrosion resistance, easy to wash and quick dry, it also has high bulkiness, It has the characteristics of good heat insulation, comfortable hand feeling and soft luster, and is widely used in home textile and clothing fields. As a hollow polyester low-elastic yar...
