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...
Embodiment 2
[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 beam net composite spinning method for splitting with different numbers of fibers according to 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 is wrapped with composite spinning to form a smooth triaxial beam mesh composite yarn with a concentric three-layer structure that is wrapped with 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 brig...
