AI Technical Summary

Problems solved by technology

The conventional two-component composite fiber has a short interface length and a long interface normal length in the cross section, so that the flexural section modulus of the fiber is large when the fiber is bent, so the fiber curl radius is large, and the crimping performance of the fiber is not ideal. After being made into fabric, the elasticity of DTY silk will gradually decrease or even disappear as time goes by, resulting in the decrease or even loss of fabric elasticity, and the elastic style of the fabric will gradually disappear.

Embodiment Construction

[0027] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

[0028] A kind of production technology of T800 composite yarn, comprises the following steps:

[0029] (a) PET slices and PBT slices are crystallized and dried respectively, and the dried PET slices and PBT slices are melted by a screw extruder respectively to obtain PET spinning melt and PBT spinning melt, and then use two-component The composite spinning box is used for spinning, and the composite POY yarn is obtained after cooling by side blowing, oiling, drafting and winding;

[0030] (b) Pass the composite POY yarn sequentially through the original wire rack, first roller, deformation heating box, cooling plate, false twister, second roller, network nozzle, auxiliary roller, shaping heating box and feeding roller, and then go through the oiling device oil, and finally through drawing and winding to obtain T800 composite yarn.

Abstract

The invention discloses a production process of T800 composite yarn, comprising the following steps: (a) crystallizing and drying PET chips and PBT chips respectively, and melting them respectively through screw extruders to obtain PET spinning melt and PBT spinning melt; The melt is then spun with a two-component composite spinning box, and composite POY filaments are obtained after side blowing cooling, oiling, drafting, and winding; , deformation heating box, cooling plate, false twister, two rollers, network nozzles, auxiliary rollers, shaping heating box and feeding rollers, oiling through the oiling device, and finally drawing and winding to obtain T800 composite yarn. The process method can successfully prepare the composite yarn with excellent crimping performance, and realize the long-term elastic style of the fabric.

Description

technical field [0001] The invention relates to the technical field of composite yarn preparation, in particular to a production process of T800 composite yarn. Background technique [0002] In bicomponent composite fibers, two components with different shrinkage rates generally form a straight interface, while bending occurs in the normal direction of the interface. The conventional two-component composite fiber has a short interface length and a long interface normal length in the cross section, so that the flexural section modulus of the fiber is large when the fiber is bent, so the fiber curl radius is large, and the crimping performance of the fiber is not ideal. After being made into a fabric, the elasticity of DTY silk gradually decreases or even disappears as time goes by, resulting in a decrease or even loss of the fabric's elasticity, and the fabric's elastic style gradually disappears. Contents of the invention [0003] The purpose of the present invention is t...
