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

Embodiment 1

[0094] Embodiment 1: recycled cotton (noil) and viscose filament three-convergence axis composite spinning

[0095] Adopt the non-equal convergence point double-bundle net composite spinning method of the present invention, two strands of viscose filament bundles are spread according to the above-mentioned non-equal convergence point double-bundle net split-spreading method, and then the front roller nip and recycled cotton fiber slivers to carry out convergent composite spinning with three converging axis coaxial 3+(2+1) structures to form a smooth composite yarn. The specific process parameters are shown in the table below. Yarn structure such as Figure 4a As shown, the wrapping protection and reinforcement of filaments to short fibers are better. The yarn hairiness index, twist angle, breaking strength, breaking elongation and yarn fineness irregularity of the spun bright and clean composite yarn are listed in the table below. Among them, the spinning rate is very high, ...

Embodiment 2

[0096] Embodiment 2: Short hair and silk three-convergence axis composite spinning

[0097] Adopt the non-equal convergence point double-bundle net composite spinning method of the present invention, spread the two strands of silk filaments according to the above-mentioned non-equal convergence point double-bundle net splitting and spreading method, and then spread them at the nip of the front roller Carry out three-convergence axis-symmetric convergence composite spinning close to the 3+(1+2) structure with short-haired fiber strands to form a smooth composite yarn. The specific process parameters are shown in the table below. Figure 4c It can be seen that the wrapping protection of filaments to short fibers and the protection and reinforcement of lateral dams are better. The yarn hairiness index, twist angle, breaking strength, breaking elongation and yarn fineness irregularity of the spun bright and clean composite yarn are listed in the table below. Among them, the spinn...

Embodiment 3

[0098] Embodiment 3: kapok / PTT filament four-convergence axis composite spinning

[0099] Adopt the non-equal convergence point double-bundle net composite spinning method of the present invention, spread the two strands of PTT filament bundles according to the above-mentioned non-equal convergence point double-bundle net splitting and spreading method, and then spread them at the front roller nip Carry out convergent composite spinning with kapok fiber strands in four-converging shaft upper cover mesh wrapping and down-going coaxial 2 2+1+1 structure to form a smooth composite yarn. The specific process parameters are shown in the table below. Yarn structure such as Figure 6f As shown, there are tow reinforcements in the short fiber strands and between them, and the contact surface between the strands is the kapok fiber itself, so the fiber cohesion is excellent, and the double wire mesh has a symmetrical wrapping protection effect on the kapok strands, preventing Loss and ...

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...
