Embodiment 1

[0067] Embodiment 1: Recycled cotton (noil) and viscose filament upper cover silk screen are all coaxial net-wrapped beam core composite spinning

[0068] Adopt the coaxial bundle net composite spinning method for unequal number of beams of the present invention, split the viscose filament bundle according to the above method and then spread the yarn, and carry out upper and middle spinning with recycled cotton fiber strands , and the lower three layers of the upper cover screen are all coaxial, and the net-wrapped beam core composite yarn is formed to form a smooth three-axis beam-net composite yarn with a concentric three-layer structure wrapped on the outside and reinforced inside. The specific process parameters are shown in the table below. The spinning formation and structure of the composite yarn are as follows: Figure 4a shown. The yarn hairiness index, twist angle, breaking strength, breaking elongation and yarn fineness irregularity of the spun bright and clean com...

[0069] Example 2: Composite spinning of net-wrapped bundle core with full coaxial short-hair and silk bottom-supporting wire mesh

[0070] Using the coaxial beam net composite spinning method for unequal number of beams of the present invention, the silk filament bundle is split according to the above method, and then the yarn is spread, and the upper, middle and lower The three-layer under-support wire mesh is fully coaxial and the net-wrapped beam core composite spinning forms a smooth triaxial beam-net composite yarn with a concentric three-layer structure of outer wrapping and inner reinforcement. The specific process parameters are shown in the table below. The composite yarn is spun Yarn spinning formation and structure such as Figure 4bshown. 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 3

[0071] Example 3: kapok / polyester filament bottom net wrapping and top wrapping composite spinning

[0072] Using the coaxial bundle net composite spinning method for unequal number of beams of the present invention, the polyester filament bundle is split according to the above method, and then the yarn is spread, and the kapok fiber strands are laminated in the middle and lower layers. The part of the tow that is wound up is coaxial with the lower support net to wrap the bundle and the top to wrap the compound spinning to form a smooth triaxial beam mesh composite yarn with a concentric three-layer structure that is wrapped with the filament and then wrapped outside. 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 ...

Abstract

The invention relates to a coaxial tow net composite yarn prepared from tows in different numbers, a spinning method and application. The tow net composite yarn is a three-layer tow net composite yarn with tows and silk nets with different filament numbers and staple fiber strands mutually reinforced and wrapped and at least an axis coaxial with the staple fiber strands and can be used for weaving fabrics and fine high-grade fabrics which have clear textures, are soft and wear-resistant, have high strength, are resistant to pilling and are beautiful and comfortable. The spinning method realizing the composite yarn is characterized by adopting a silk spreading and splitting device to split filament tows into two asymmetric silk layers after spreading the filament tows into silk layers, wherein one silk layer goes straight or is led downward and is spread into a silk net by a silk spreading device; the other silk layer descends or ascends and is clustered; and the two silk layers and the staple fiber strands form upper, middle and lower axes to be synchronously fed into a front roller jaw and form the three-axis tow net composite yarn in a twisting triangle area. The method is suitable for spinning the protective, soft, smooth, clean, high-count and ultrafine-count composite yarns with ultrashort fibers liable to flock drop and flying and shorter and weaker recycled fibers.

Description

technical field [0001] The invention relates to a coaxial bundle net composite yarn with unequal numbers of beams, the spinning method of the composite yarn, the application of the composite yarn and the spinning method, and belongs to the filament bundle in the field of ring spinning. Composite spinning technology of splitting with equal number of strands and internal reinforcement and external wrapping protection for staple fiber strands after unfolding. 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 ...
