AI Technical Summary

Problems solved by technology

The method combines the dyeing process of the medium-temperature reactive dye and the delint process of the neutral cellulase into a one-bath dip-dyeing process, which solves the problems of high energy consumption, unstable color shade and labor intensity in the two-bath process of reactive dyeing and depilation of garments. Large and time-consuming problems

Abstract

The invention discloses a one-bath process for dyeing and burring ready-made clothes, belonging to the textile field and relating to performing one-bath dip dyeing processing for a medium-temperature active dye dyeing process and a neutral cellulase burring process. Compared with the two-bath process of dyeing and burring ready-made clothes, the one-bath process is greatly improved in several aspects like energy consumption, colored light stability, labor intensity and time consumption, and simultaneously solves the problems of environmental protection and cost; and the cloth face effect of the clothes is different from that of the two-bath process.

Description

technical field [0001] The invention relates to a garment dyeing process, in particular to a one-bath process for garment dyeing and hair removal. Background technique [0002] In the process of reactive dyeing of ready-made garments, clothes are prone to fluffing, and some gray fabrics have more fluff. Therefore, after reactive dyeing of ready-made garments, hair removal treatment is usually required to remove the fluff on the surface of the clothes to improve the appearance of the clothes. The traditional process is to remove the hair in another bath after dyeing. The traditional process has the following disadvantages: (1) The process flow is very long, and the consumption of water, electricity and steam is large. (2) And because the hair removal process is carried out by using cellulase (enzyme water) at a lower pH value, it is easy to affect the color and shade of the garment. Especially for some sensitive colors, most of these colors need to be re-colored after hair ...
