Silk net covering type 2*2 axis composite yarn, spinning method and application

Abstract

The invention relates to a silk net t covering type 2*2 axis composite yarn, a spinning method and application. The composite yarn is 2*2 axis composite yarn which is formed by covering and compositing two short fiber whiskers on two silk nets respectively and comprises a net wrapping form, a net wrapping net covering form and a net covering form. The composite yarn in the net wrapping form, the net wrapping net covering form and the net covering form can be woven into textiles which are clear in texture, soft and wear-resistant, high in intensity, and attractive in appearance and comfortable and resist fluffing and pilling and high-grade fine fabric. According to the spinning method for the composite yarn, twizzles, bunchers and filament spreading devices are arranged on a ring spinning machine, two bundles of filaments are centered by a left twizzle and a right twizzle, then enter the respective filament spreading devices and are spread so as to form two covering silk nets; the two covering silk nets and the short fiber whiskers which are positioned by the bunchers enter a front roller jaw synchronously in upper and lower layers, the respective short fiber whiskers are wrapped and wound at a twisting triangular area, and the respective short fiber whiskers and the filaments are composited to form the composite yarn. The method is suitable for spinning soft, smooth and clean, high-count protective composite yarn of ultrashort fibers with high scrap falling and flying possibility and weak reclaimed fibers.

Description

technical field [0001] The invention relates to a screen-covered 2×2 axis composite yarn, a spinning method of the composite yarn, an application of the composite yarn and 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] At present, the staple fiber / filament composite yarn production devices are partially modified on the basis of the traditional ring spinning mechanism. Such as Wang Wenge and Li Baocang's utility model patent (patent...

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
