Technical Field

The invention belongs to the technical field of spinning, and particularly relates to a dyeing and finishing process of clothing fabric.

Background

Dyeing and finishing textile materials (fibers, yarns and fabrics) are subjected to a process based on chemical treatment, also known in the modern literature as printing and dyeing, which together with spinning, weaving or knitting production forms the whole process of textile production, the dyeing and finishing including pretreatment, dyeing, printing and finishing. The quality of dyeing and finishing quality has important influence on the use value of textiles, and Chinese invention patent CN106637903A discloses a dyeing and finishing process of clothing fabric, which comprises the following steps: the first step is as follows: singeing; the second step is that: desizing; the third step: bleaching; the fourth step: heat setting; the fifth step: dyeing; and a sixth step: after finishing; the seventh step: tentering and shaping; the general chemical auxiliaries used in the merging in the dyeing and finishing process are common in the market, high-end equipment is not needed, the whole process is simple, the process conditions are easy to control, and the dyeing and finishing process is safe and environment-friendly; in addition, by the process, a large amount of fabric dyeing and finishing can be carried out at one time, so that the processing efficiency is guaranteed; the original excellent characteristics of the fabric are retained, the four-prevention performance is good, the strength loss is small, the dyeing fastness is high, the breathable function is realized, the process is reasonable, and according to detection, all chemical indexes of the product meet the requirements; however, the cloth, especially the cotton fiber cloth, is loose after heat setting treatment, and has poor strength, elongation and dye absorption capacity, so that the quality of the formed subsequent cloth is affected, and the practicability is low.
