Problems solved by technology

Due to the weak cohesion 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.
[0005] Chinese patent CN1403639 discloses a special-shaped self-curling polyester fiber, different shrinkage T400 fiber, etc. These fibers belong to side-by-side two-component fibers, and the manufacturing process is complicated

Abstract

The invention relates to a preparation method of a lodging-resistant multi-difference polyester low elastic filament. The preparation method comprises the following steps: firstly, mixing nano sepiolite fibers, organic magnesium hydroxide whisker, organic barium sulfate nano powder, ethylene glycol, propylene glycol, p-hydroxybenzoic acid and sodium germanate to obtain a high-modulus composite alcohol solution; secondly, mixing organic wollastonite nano needle-like fibers, mica powder, polyethylene glycol, the propylene glycol, an antioxidant 1010, ethylene glycol antimony and protonated agent phosphoric acid to obtain a high-modulus composite promoter; thirdly, co-polycondensing the high-modulus composite multifunctional alcohol solution and the high-modulus composite promoter with purified terephthalic acid and the ethylene glycol to obtain high-modulus modified polyester; a melt of the high-modulus modified polyester is sprayed from a T-shaped spinneret orifice in a spinneret plate; the lodging-resistant multi-difference polyester low elastic filament is prepared by a special cooling mode and a low-temperature texturing process. The fiber prepared by the preparation method has multiple different properties of different crystallization, different orientation and different shrinkage; after different shrinkage, the appearance is good, and a brushed fabric prepared from the lodging-resistant multi-difference polyester low elastic filament is not easy to lodge.

Description

technical field [0001] The invention relates to a manufacturing method of anti-lodging polyisopolyester low elastic yarn, belonging to the technical field of textile fiber manufacturing. Background technique [0002] The flat yarns produced at present have a high degree of irregularity, and the gloss is also good when making plush fabrics. [0003] In addition, the more common iso-shrinkage fibers on the market at present are mostly prepared by the method of network plying of two or three filaments with different shrinkage ratios; they are also prepared by the method of parallel bicomponent spinning. [0004] Chinese patent 103484967A discloses a preparation method of copolyester melt ultra-high-speed direct spinning controllable multi-isolation shrinkage composite fiber, Chinese patent 102140700A discloses a preparation method of double iso-shrinkage mixed fiber, Chinese patent 101962838A discloses A preparation method of polyester superfine differential shrinkage composit...
