Unequal rendezvous point spinning method of asymmetrical beam splitting spread filament, composite yarn and application

Abstract

The invention relates to an unequal rendezvous point spinning method of an asymmetrical beam splitting spread filament, a composite yarn and application. The composite spinning method comprises the steps of: adopting a splitter and a filament spreading device; and splitting two beams of filaments into 2*2 beams including two upstream beams and two downstream beams asymmetrically through the splitter; enabling the four beams to enter into respective filament spreading devices to form filament meshes; then feeding the filament meshes at different positions; wrapping a short fiber whisker strip in a twisting triangular zone and multi-level converging to compound the filament mesh wrapping composite yarn. The method is suitable for spinning of protective, soft, smooth and high-count composite yarns of fibers which are ultra-short, easy to drop scraps and easy to generate flying and shorter and weaker fibers. The obtained composite yarn is a filament mesh wrapping six-shafting composite yarn at least having three convergent shafts and at least two rendezvous points being not on the same horizontal line. The composite yarn has four ways of the convergent shafts and can be used for weaving soft, abrasion-resistant, beautiful and comfortable textiles with clear texture, high intensity and pilling resistance and high-level fine fabrics.

Description

technical field [0001] The invention relates to a spinning method with different convergent points for asymmetric beam splitting and spreading, a composite yarn prepared by the spinning method, the spinning method and the application of the composite yarn. Background technique [0002] Fiber is a resource that requires land to produce and oil to manufacture. Land is limited and food needs to be grown; oil reserves are dwindling for energy. On the one hand, people have begun to utilize recycled fibers, such as noils and noils in textile processing, and short and weak fibers obtained from the opening of recycled textiles. This is an important way to recycle fibers. On the other hand, some ultra-short and fragile fibers that were originally considered non-spinnable, such as kapok and down, have also begun to be paid attention to and utilized as new fiber resources. However, these short and weak fibers not only cause flying, serious shavings and low yield in spinning, but also...

Problems solved by technology

[0006] The above-mentioned related methods, one of them, are spinning for the purpose of changing the yarn style and fancy or high-branching of fibers with excellent spinnability, and fibers with poor spinnability or cannot be spun at all cannot be used; Second, it is more suitable for high-branched and even ultra-high-branched spinning of short and weak fibers
