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.

Abstract

The invention discloses a softening treatment process of cotton fiber. The softening treatment process is characterized by adding folium mori micro powder and isoalcohol polyoxyethylene on the basis of the conventional softening process of cotton fiber, and effectively dispersing the folium mori micro powder in organosilicone continuous films on the surfaces of fabrics. The treated cotton fiber has a good antibacterial effect and also has excellent yellowing resistance; natural dyes and plant antibacterial agents are used in the treatment process; the treated cotton fiber is environment-friendly and healthy.

Description

technical field [0001] The invention relates to the technical field of cotton textiles, in particular to a cotton fiber softening treatment process. Background technique [0002] At present, the production of cotton colored spinning mainly adopts alkali treatment. There are many problems in this method, mainly because the pretreatment and dyeing of cotton fibers are the key processes of the colored spinning process. In addition to 94% cellulose fiber, cotton fiber also has 6% impurities (cellulose symbiosis such as pectin, wax, ash, etc.). 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 to remove impurities such as pectin and wax in cotton fibers, and at the same time, 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. ...
