Embodiment 1
[0070] Example 1: Recycled cotton (noil) and viscose filament three-convergence shaft screen wrapping composite spinning
[0071] Using the unequal convergence point composite spinning method for asymmetric beam splitting and spreading of the present invention, the two strands of viscose filament bundles are spread according to the above-mentioned asymmetric beam splitting and spreading method, and then at the nip of the front roller The three-convergence axis wire-wrapped composite spinning is carried out with recycled cotton fiber strands to form a smooth composite yarn. The specific process parameters are shown in the table below. The converging form and yarn structure of the spun yarn are as Figure 3a 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 l...
Embodiment 2
[0072] Example 2: Wrapping Composite Spinning of Short Hair and Nylon Four Converging Shaft Screens
[0073] Adopt the unequal convergent point composite spinning method for asymmetric beam splitting and spreading of the present invention, spread the two strands of nylon filament bundles according to the above-mentioned asymmetric splitting and spreading method, and then at the front roller nip place and The short-haired fiber strands are spun with four-converging axis wire mesh wrapping composite yarn to form a smooth composite yarn. The specific process parameters are shown in the table below. The converging form of spinning and the yarn structure are as follows: Figure 4b 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 flo...
Embodiment 3
[0074] Example 3: kapok / polyester filament four-convergence axis screen-wrapped composite spinning
[0075] Adopting the unequal convergent point composite spinning method for asymmetric beam splitting and spreading of the present invention, the two strands of polyester filament bundles are spread according to the above-mentioned asymmetric beam splitting and spreading method, and then at the nip of the front roller and The kapok fiber strands are spun with four converging shafts and wrapped in wire mesh to form a smooth composite yarn. The specific process parameters are shown in the table below. The converging form and yarn structure of spinning are as follows Figure 5a 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 flower...
