Problems solved by technology

However, in the traditional printing and dyeing process, dyeing and finishing are two independent processes, which makes the printing and dyeing process complicated and the production efficiency low.
[0004] In addition, the dyeing liquor used in the traditional printing and dyeing process contains a large amount of non-degradable and harmful printing and dyeing auxiliaries, which makes the waste liquor difficult to handle and endangers the environment and human health.

Abstract

The invention discloses a printing and dyeing process of a cotton fabric. The printing and dyeing process comprises the steps of pretreatment of the fabric, and dyeing treatment, wherein the dyeing treatment comprises the steps of soaking the fabric subjected to pretreatment in a dye vat for dyeing, controlling the bath ratio of the dye vat to be 1:(12-15), carrying out dip dyeing for 8-10min at 25-30 DEG C, heating to be at 58-60 DEG C and carrying out dip dyeing for 15-25min. Dye liquid in the dye vat contains dye, N-methylolacrylamide, alpha-olefin sulfonate, methyl diphenyl ether disulfonate, a poly(quaternary ammonium dye-fixing agent, sodium silicate and other components; according to the printing and dyeing process, the operation is convenient, few procedures are needed, the energy consumption is low, the printing and dyeing efficiency is high, and waste liquid caused by printing and dyeing process is easy to treat.

Description

technical field [0001] The invention relates to the field of textile production, in particular to a printing and dyeing process for cotton fabrics. Background technique [0002] The textile industry is a traditional pillar industry in my country, including five parts: textile, printing and dyeing, chemical fiber, clothing and textile equipment. Fabric refers to textiles made of natural fibers or synthetic fibers, which can be divided into woven fabrics, knitted fabrics and non-woven fabrics according to different processing methods. Printing and dyeing refers to dyeing with dyes to make fabrics show various colors that people need to make them more beautiful. The traditional printing and dyeing process includes desizing, scouring, bleaching, mercerizing, dyeing, printing, finishing and other processes. Among them, the three processes of desizing, scouring and bleaching are fabric pretreatment. The purpose of cotton fabric and its blended fabric pretreatment is to remove the...
