Symmetrical beam-splitting filament-spreading double-lower support 2*2 shafting composite yarn, spinning method and application

Abstract

The invention relates to a symmetrical beam-splitting filament-spreading double-lower support 2*2 shafting composite yarn, a spinning method and application. The composite yarn is a 2*2 shafting mesh wrapping, mesh wrapping and coating and mesh coating composite yarn which is compounded after two filament meshes respectively support and wrap short fiber whisker strips from downsides; and the composite yarn 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. The method for producing the composite yarn comprises the steps of: adopting a yarn guide hook, a splitter, a beam concentrator and filament spreading devices all of which are mounted on a ring throstle; after splitting the filament into two beams by using the splitter, downwards guiding the beams by left and right filament guide hooks and feeding the beams into respective filament spreading devices for filament spreading in a centering manner and forming tow paths of lower-supporting filament meshes; enabling the spread filaments and the short fiber whisker strips located by the beam concentrator to enter into the front roller in a manner of upper and lower layers; wrapping respective short fiber whisker strips in a twisting triangular zone and compounding to form the composite yarn. The method is suitable for spinning of protective, soft, smooth and high-count and superfine composite yarns of fibers which are ultra-short, easy to drop scraps and easy to generate flying and shorter and weaker fibers.

Description

technical field [0001] The invention relates to a 2×2 axis-based composite yarn of the beam-splitting and spreading double-supporting protection type in the spinning field, a spinning method of the composite yarn, an application of the composite yarn and an application of the spinning method. 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 be fully utilized. [0003] Simultaneously, for convenience and high yield in the existing filament processing, thicker filaments are all produc...

Problems solved by technology

[0005] 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
