Problems solved by technology

Especially for the processing of high-density fabrics, due to the shedding, picking, and beating-up movements of the loom, the yarn is subject to strong mechanical effects such as stretching, impact, and twists, and it is also closely related to loom components such as healds, reeds, and warp stoppers. There is a severe friction effect; in addition, each warp yarn not only has friction between each other, but also contacts with tens of thousands of weft yarns successively. These are easy to cause the warp yarns to fluff and even break, causing serious parking, which not only reduces production efficiency, but also affects the quality of the fabric

Abstract

The invention discloses a preparation method of a waterproof shell fabric. The preparation method comprises the steps of examining precursor fiber, treating warp, weaving on a weaving machine and cropping; the warp treatment comprises six steps, namely hanging yarn, beaming, slashing, combining axles, leasing, as well as drafting and scrabbling reed. Starching is performed on warp, reasonable technological parameters are adopted, and specific sizing percentage control is performed, so that the inner layer of yarn is immersed in seriflux, cohesive force between fibers is increased, and breaking-resisting strength of yarn is improved; a layer of protective film is formed on the surface of the yarn, so that the yarn is smoother and wear-resisting, the warp can bear strong mechanical action of the weaving machine and repeated abrasion among yarns, the end breakage rate of the warp during weaving is reduced, and the weavability of the warp and the quality of the waterproof shell fabric are improved.

Description

technical field [0001] The invention relates to a preparation method of a fabric, in particular to a preparation method of a waterproof fabric. Background technique [0002] The yarns used for weaving fabrics include natural fibers such as cotton, wool, hemp, and silk, and chemical fibers such as polyester and acrylic fibers. During the weaving process, the warp and weft yarns must bear different forces. Especially for the processing of high-density fabrics, due to the shedding, picking, and beating-up movements of the loom, the yarn is subject to strong mechanical effects such as stretching, impact, and twists, and it is also closely related to loom components such as healds, reeds, and warp stoppers. There is a severe friction effect; in addition, each warp yarn not only has friction between each other, but also contacts with tens of thousands of weft yarns successively. These are easy to cause the warp yarns to fluff and even break, causing serious parking, which not only...
