Problems solved by technology

Due to the weakness of the cohesion force between the tows, the network-bonded fibers often have unsatisfactory appearance after shrinkage
In addition, due to mechanical reasons in the plying process, it is easy to cause unevenness of the tow, which affects the use of the subsequent process, and even ultimately affects the appearance quality of the fabric.
[0004] Chinese patent CN1403639 discloses a special-shaped self-curling polyester fiber, different shrinkage T400 fiber, etc., but these fibers belong to side-by-side bi-component fibers, and have the disadvantage of complicated manufacturing process

Abstract

The invention relates to a method for producing multi-difference multi-functional polyester low elastic yarn. The method comprises 1) mixing calcium carbonate whisker, sepiolite fibers, mica powder, ethylene glycol, propylene glycol, butanediol, p-hydroxybenzoic acid and sodium germanate to obtain an enhanced composite alcoholic solution, 2) mixing magnesium hydroxide whisker, barium sulfate powder, polyethylene glycol, propylene glycol, a high temperature antioxidant 1098, ethylene glycol antimony and protonating agent phosphoric acid to obtain an enhanced composite promoter, 3) carrying out multielement copolycondensation on the enhanced composite multi-functional alcohol solution, the enhanced composite promoter, refined terephthalic acid and ethylene glycol to obtain an enhanced modified polyester, ejecting the melt of the enhanced modified polyester through antiparallelogram-like spinneret orifices, and preparing the multi-difference multi-functional polyester low elastic yarn through a specific cooling curing method and an elasticity improvement technology. The method is simple. The produced fibers are one-component different shrinkage fibers, which have different crystallinity, different orientation and different shrinkage performances, and the appearance and form of the fiber subjected to different shrinkage are good.

Description

technical field [0001] The invention relates to a method for manufacturing multi-different and multi-functional polyester low elastic yarns, belonging to the technical field of textile fiber manufacturing. Background technique [0002] At present, the different shrinkage fibers that are common in the market are mostly produced by using two or three strands of filaments with different shrinkage ratios for network plying; there are also parallel two-component spinning methods. [0003] Chinese patent 103484967A discloses a method for preparing copolyester melt ultra-high-speed direct spinning controllable multi-differential shrinkage composite fiber, Chinese patent 102140700A discloses a preparation method for double different shrinkage mixed fiber yarns, and Chinese patent 101962838A discloses The invention discloses a method for preparing polyester superfine different-shrinkage composite filaments, but these fibers belong to network ply different-shrinkage fibers. Due to th...
