Abstract
The invention relates to a method for processing silk imitated polyester filament different shrinkage air multi-textured yarns. In the method, wound polyester filaments or pre-drafted filaments with common round sections are taken as raw materials; in a different shrinkage yarn preparing procedure, different shrinkage yarns with 2 to 10 components are drafted by 1 to 5 times at the temperature of between 90 and 180DEG C; in an air-textured processing procedure, under the condition of high pressure air injection eddy, a parallel feeding mode is adopted, and the overfeed rate is 8 to 10 percent; in a textured processing procedure, air-textured yarns of polyester filament different shrinkage composite filaments are subjected to once heat treatment at the temperature of between 180 and 200DEG C for 0.5 to 1 minute; and a silk-like processing procedure of alkali peeling or alkali etching is performed. Compared with simple air-textured yarns, the novel yarns have more obvious hair imitation effect, the flexibility, plumpness, elasticity and gloss of the textured yarns are obviously improved, and the novel yarns have special hair imitation effect.
Description
Technical field
The invention belongs to field of textiles, it relates to a kind of polyester filament iso-shrinkage air multi-textured yarn with Silk effect.
Background technology
Utilize the action of turbulent flow principle of compressed air in nozzle, make two groups of identical chemical fiber filaments of feeding speed form the parallel warp structure or two different group leader's silks of feeding speed are formed to have typical skin-core structure, the manufacturing air deformation yarn has been universal technology now.(Wang Shanyuan. textured yarn [M]. Shanghai: Shanghai science tech publishing house, 1992).The method that adopts the different chemical-fibres filaments of multicomponent shrinkage factor to make iso-shrinkage air multi-textured yarn is also reported to some extent, they be imitative botany and wool fabric important source material (Jiang Yan. different contractile filaments air-texturing (multi-texturing) processing yarn formation structure and performance. Donghua University's thesis for the doctorate, 2006.).
But adopting the method for chemical fiber filament deformation processing, carry out the processing effect of tweed yarn and wool fabric, with regard to present level, no small gap is arranged still, mainly is that feel and gloss still have improved necessity.
Summary of the invention
The invention provides a kind of polyester filament iso-shrinkage air multi-textured yarn with Silk effect, compare with simple air deformation yarn, its feel is more soft, and gloss is more soft.
The technical scheme that the present invention solves the problems of the technologies described above is as follows:
Processing method and the principle of silk imitated polyester filament different shrinkage air multi-textured yarns of the present invention are as follows:
(1) selection of raw material:
Select terylene coiling terylene or give drafted fibre, adopt the typical circular cross section, be convenient to the carrying out of alkali peeling chemical reaction, obtain preferably luster effect.
(2) preparation of different contractile filaments
For the drawing-off of chemical-fibres filaments through different multiples, then under different conditions, heat-treat, can obtain each component silk of different shrinkage factors, be called different contractile filaments, generally finish at parallel drafting machine, the improvement technique that this machine adopts is for selecting the 3-10 component raw material, and each component raw material adopts different drafting multiple (1-5 doubly), and each component raw material adopts 90 ℃ 200 ℃ of different hot plate temperatures.General drafting multiple is higher, the hot plate treatment temperature is higher, and the percent thermal shrinkage of gained strand is larger.
(3) air-texturing processing
Air-texturing processing is under the effect of pressure-air jet-stream whirl, form and the ordered arrangement of chemical-fibres filaments fragment are damaged, form disorderly structure, it is so-called high bulkiness chemical-fibres filaments, for the present invention, this process modification be that raw material tow over feed rate(OFR) is 8%-10%, before real silk, the textured yarn close structure some for well.
(4) different contraction distortion processing
This operation is that air deformation yarn with the polyester filament abnormal contraction composite filament is again through a heat treatment, should be in the improvement technique of this operation for the present invention: this operation treatment temperature is not too high before real silk, it is 180 ℃, 0.5～1.0 minute processing time, raising with control fibre crystallinity and degree of orientation brings difficulty to real silk.
(5) real silk processing
Polyester filament is processed through air-texturing processing and different contraction distortion processing, make the form of long filament and the ordered arrangement between the long filament that great variety occur, make the textured yarn high loft, wool-like effect is arranged, but the cross section of filament fiber is-or circle, the surface is smooth, through the real silk processing, also claims after the processing of alkali peeling processing or alkaline etching, the polyester filament surface is etched, fiber attenuates simultaneously, and textured yarn is more soft after processing, and gloss is more soft.
Should illustrate that it is unsatisfactory directly to adopt ultra-fine polyester filament to prepare the effect of iso-shrinkage air multi-textured yarn.
Compared with prior art advantage of the present invention is as follows: iso-shrinkage air multi-textured yarn and simple air deformation yarn are compared, its wool-like effect obviously manifests, but the wool-like effect of common iso-shrinkage air multi-textured yarn still has certain gap, the real silk iso-shrinkage air multi-textured yarn is to set about from the long filament modification, improve the performance of textured yarn, fibre length behind the real silk attenuates, the surface is etched, rough and uneven in surface, make softness, fullness elasticity and the luster performance of textured yarn obtain obviously to improve, have special wool-like effect.
The specific embodiment
The present invention will be helped further to understand by following embodiment, but content of the present invention can not be limited.
Work flow of the present invention is as follows: the different contraction preparation section that is comprised of raw material, parallel drafting machine, hot plate and bobbin etc.; The air-texturing manufacturing procedure that is formed by input roller, wetting apparatus, air nozzle, delivery roller, coiling bolt and groove drum etc.The different contraction distortion manufacturing procedure that is formed by input roller, heat treatment box and delivery roller etc. and form by inputting four parts such as real silk chemical industry order that roller, real silk groove and delivery roller etc. form.
