Manufacturing technology for yarn with cowboy style

Abstract

The invention discloses a manufacturing technology for yarn with a cowboy style, and belongs to the technical field of textile. The manufacturing technology is characterized by comprising the following steps: 1, preparing colored leather yarn, that is, taking various bulk fibers, coloring the bulk fibers, mixing the colored bulk fibers in a certain proportion, and manufacturing the colored leather yarn through a fore-spinning process; 2, selecting heart yarn which is one or more of staple yarn, filament yarn, twisted yarn and air textured yarn; and 3, spinning, that is, feeding the colored leather yarn and the heart yarn into semi-open-end spinning equipment, so as to obtain the yarn with the cowboy style. The yarn prepared by the invention has the advantages that the raw materials are abundant; the colors are various; and the energy consumption and the pollution are low.

Description

Technical field: [0001] The invention relates to a production process of a denim-style yarn, which belongs to the technical field of textile fabrics. Background technique: [0002] Denim clothing has always been the mainstream clothing that people love. Its main style is uneven whitening. During the process of wearing and washing denim clothing, the dyes in some parts will fall off, resulting in uneven whitening, and the effect of whitening with washing. [0003] At present, in order to obtain the above-mentioned denim fabrics or denim garments, it is generally twill fabrics woven from cotton yarns, which are dyed with cyanide, vat, and sulfur dyes. Because the denim fabrics require surface dyeing, the inner core is still white, so that it can be cleaned after washing. 1. During the color grinding process, an unbalanced dew-white effect can be obtained. Therefore, the choice of dyes and the choice of dyeing process are greatly restricted. The main problems are as follows: ...

AI Technical Summary

Problems solved by technology

[0004] 1. The color is single. The denim fabrics currently produced are not rich in color, because only the dyeing process of cyanide, vulcanization, and vulcanization can be used, and the color spectrum is single and dark, so it is impossible to obtain more rich and bright colors;

[0005] 2. The raw material is single. At present, due to the limitation of dyestuff and dyeing process, the main raw material of denim fabric can only choose a few fibers such as cotton, and various new textile materials cannot be used.

This limits the subsequent weaving and finishing processes, as well as the wearability of denim fabrics

Difficulty in cost control

[0006] 3. Because the existing denim fabrics are dyed with starch, vulcanization, and vulcanization, the clothes made need to be washed and polished again, resulting in increased costs and environmental pollution.

[0007] Based on this, the existing problems in the prior art are: 1. Solve the problem of single and dark gray denim fabrics; 2. Solve the problems of single raw materials of existing denim fabrics and limited dyes and dyeing processes
