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

[0073] Example 1: Composite spinning of recycled cotton (noil) and viscose filament bundles right next to the lower wire wrapping wire

[0074] Adopting the non-equal beam splitting composite spinning method of the present invention, the viscose filament bundle is split according to the above-mentioned method, and then the yarn is spread, and the tow is right-handed with the recycled cotton fiber strands. Close to the composite spinning of the dam protection and the protective cotton fiber slivers wrapped in the bottom support wire mesh net to form a smooth triaxial bundle mesh composite yarn. The specific process parameters are shown in the table below. The spinning forming and structured as Figure 4ashown. 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, which means that there is very little loss...

Embodiment 2

[0075] Example 2: Composite spinning of short hair and silk bundle right next to the net under the net

[0076] Using the non-equal beam-splitting composite spinning method of the present invention, the long silk tow is split according to the above-mentioned method, and then the yarn is spread, and the tow is left close to the short-haired fiber strands. Composite spinning of dam-building protection and net-wrapping short-haired fiber strands to form a smooth triaxial beam net composite yarn. The specific process parameters are shown in the table below. The spinning shape and structure of spinning the composite yarn are as follows: Figure 5b shown. 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, which means that there is very little loss of fiber such as flying flowers, shavings, and broken ends; ...

Embodiment 3

[0077] Embodiment 3: composite spinning of kapok / PTT filament tow net

[0078] Using the non-equal beam-splitting composite spinning method of the present invention, the PTT filament bundle is split according to the above-mentioned method, and then the yarn is spread, and the kapok fiber strands are wrapped in a left-displaced net of the silk screen. Composite spinning of protection and under-wrapping of tow to form a smooth three-axis beam mesh composite yarn. The specific process parameters are shown in the table below. The spinning shape and structure of spinning the composite yarn are as follows: Figure 6b As shown, the overlapping degree of the upper cover of the silk screen and the staple fiber strand is about 65%. 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, which means that there is very...

Abstract

The invention relates to a nonequivalent beam splitting different-shaft-beam-net composite yarn, a spinning method and application. The composite yarn is a close net-wrapped yarn, a close net-wound yarn, a dislocated net-wrapped beam coating yarn and a beam-net coating and winding yarn formed by three-axis system composite spinning of tows and silk screens with nonequivalent filament numbers and staple fiber bars; and the composite yarn can be used for weaving textiles and high-grade fabrics with clear grains, flexibility, wear resistance, high strength, fuzzing and pilling resistance, attractiveness and comfortableness. According to the spinning method for the composite yarn, endless tows are unfolded to form a filament layer which is spit into two silk layers with nonequivalent numbers by adopting a filament unfolding and spitting device; one silk layer straightly travels or is downwardly led to be unfolded by a filament unfolding device to form a silk screen from top to bottom or is separated; and the other silk layer downwards travels or upwards travels to enable a bundle to be tightly close or separated, is synchronously fed with the stable fiber bars and is twisted to from a beam net composite yarn with a wrapping structure. The spinning method is suitable for spinning protective, soft and smooth, high-count and superfine-count composite yarn formed by super-short fibers, fibers which easily fall scrip and easily fly as well as extremely-short and extremely-weak reclaimed fibers.

Description

technical field [0001] The present invention relates to a non-equal beam-splitting composite yarn with different axial beams, the spinning method of the composite yarn, the composite yarn and the application of the spinning method, which belong to the non-woven fabric of filament bundles in the field of ring spinning. Multi-side protective compound spinning technology for staple fiber strands after equal beam splitting and unwinding. 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 ...
