Cotton fiber comprehensive treatment process

Abstract

The invention relates to a cotton fiber comprehensive treatment process, which comprises a pretreatment process, a dyeing process, a softening process and a spinning process, wherein the pretreatment process sequentially comprises carrying out boiling water boiling, an alkaline pectinase impregnation treatment and water washing on cotton fibers, the dyeing process comprises: soaking the cotton fibers for 15 min with a dye solution at a temperature of 60 DEG C, soaking for 15 min with a NaCl solution, increasing the temperature to 90 DEG C, and soaking for 30 min with a Na2CO3 solution at the temperature of 90 DEG C, and the softening process comprises: adopting a softening agent solution to soak the cotton fibers for 50-70 min at a temperature of 50-60 DEG C and drying until the water content is 8-10%, wherein the amount of organosilicon is 9-11 g / L. With the process, conditions of molecule chain oxidative cleavage, polymerization degree reduction and fiber strength reduction of cellulose, and environmental pollution are avoided.

Description

technical field [0001] The invention belongs to the textile field and relates to a cotton fiber comprehensive treatment process. Background technique [0002] Advantages of Cotton Fiber Dyeing Technology A color spun fabric is gorgeous and beautiful, with clear layers, and can produce colorful fashion fabrics. It can be dyed in a variety of colors according to human requirements, and the color is bright. It can carry out mixed spinning, and there can be a variety of different colors on one yarn, which can produce unexpected effects and overcome the shortcomings of traditional cotton yarn and gray cloth dyeing. B In the traditional "spinning-weaving-dyeing and finishing" process, only one color can be obtained at a time during the dyeing and finishing process. For varieties with many designs and colors, the dyeing process can only be repeated, and the color light is difficult to control, and the production cycle is long. high cost. First dye the cotton fiber, then adjust t...

AI Technical Summary

Problems solved by technology

The presence of these impurities makes the cotton fiber poor in hygroscopicity and difficult to dye in the subsequent process.

The traditional process uses alkali treatment. While removing impurities such as pectin and wax in cotton fibers, it not only oxidizes and breaks some cellulose molecular chains, reduces the degree of polymerization, and reduces the strength of fibers, but also seriously pollutes the environment.
