Non-equal convergent point double tow-screen composite yarn, spinning method and application

Abstract

The invention relates to a non-equal convergent point double tow-screen composite yarn, a spinning method and application of the composite yarn. The composite yarn with six lines of shafting is formed by at least compositing three convergence shafts, double tows and screens at least with two convergent points not on the same level and staple fiber strands and can be used for weaving fabrics and high-grade fine fabrics which have clear textures and high strength, are soft and wear-resistant, are resistant to fuzzing and pilling and are beautiful and comfortable. The spinning method realizing the composite yarn is characterized by adopting a splitting machine with yarn spreading function and left and right yarn spreading machines and splitting two filaments into 22 tows asymmetrically with the splitting machine, wherein two tows are directly fed into a front roller jaw and another two tows enter respective yarn spreading machine to be spread into screens and then are fed into the front roller jaw and form the multi-stage converging and compositing double tow-screen composite yarn which reinforces tows of the two staple fiber strands and protects the screens in the twisting triangular space. The method is suitable for spinning protective, soft and smooth high-count composite yarns with super-staple fibers, fibers liable to drop of chips, fibers liable to flying and shorter and weaker reclaimed fibers.

Description

technical field [0001] The invention relates to a non-equal convergence point double-bundle net composite yarn, the spinning method of the composite yarn, the composite yarn and the application of the spinning method, which belong to the splitting of filament bundles into bundles in the field of ring spinning Protective compound spinning technology for net. Background technique [0002] With the rapid development of the textile industry, short and weak fibers such as noil and noil increase in the textile processing process; the fibers obtained from recycled textiles have a certain gap in length and strength compared with the original fibers; Some new ultra-short and fragile fibers, such as kapok and down, have begun to be paid attention to and utilized. The yarns spun from these shorter and weaker fibers have low strength and more hairiness. As a result, this type of short and weak fibers cannot be fully utilized. [0003] Simultaneously, for convenience and high yield in...

AI Technical Summary

Problems solved by technology

[0005] The above-mentioned related methods, firstly, are all spinning for the purpose of changing the yarn style, fancy or high-branching of fibers with excellent spinnability, and cannot be used for spinning fibers with poor spinnability or fibers that cannot be spun at all. Second, it is not suitable for high-branched or even ultra-high-branched composite spinning of short and weak fibers
