Cotton fabric dyeing anti-wrinkle one-bath-process processing technique

Abstract

The invention relates to a cotton fabric dyeing anti-wrinkle one-bath-process processing technique and belongs to the technical field of treatment of fabric and the like. The processing technique includes: soaking fabric in a blended solution of dye, resin and auxiliaries; padding before baking, wherein in the blended solution, the dye is active dye, adding amount of the dye is 20-25 g / L, the resin is non-ironing resin, adding amount of the resin is 140-160 g / L, a softener is 15-30 g / L, a penetrant is 0.3-3 g / L, and padding allowance is 60-100%. The processing technique is applied to treatment of cotton fabric and has the advantages of short process, high color fastness and good anti-wrinkle performance.

Description

technical field [0001] The invention relates to a cotton fabric dyeing anti-wrinkle one-bath process, which belongs to the technical field of fabric treatment. Background technique [0002] Cotton fiber is the most used natural textile fiber in the world, and it is usually dyed with reactive dyes at present. Like most cellulose fibers, cotton fibers will generate negative charges due to the ionization of hydroxyl groups when they come into contact with water, and reactive dyes are anionic dyes, so that the fibers and dyes repel each other due to the same electrical property, so usually There is the problem of low dyeing rate. In the traditional dyeing process, it is necessary to add a large amount of salt (such as sodium chloride, sodium sulfate) to promote dyeing, improve the dyeing rate, and to add alkali to fix the color. The use of a large amount of salt and alkali in the dyeing process not only increases the cost of dyeing, but also increases pollution emissions. At ...

Problems solved by technology

However, the defect of the process is that the process is long and there are many processes. Post-processing such as dyeing and color fixing needs to be completed in multiple processes and steps. Anti-wrinkle, dyeing, and color fixing cannot be carried out simultaneously.
