Problems solved by technology

However, in this process, the molecular structure of many disperse dyes will change under high temperature and alkaline conditions by using urea and baking soda, which will cause the hydrolysis of some dyes and reduce the dyeing performance; and it is easy to make the fabric yellow. , the surface of the cloth is dark, which has a direct impact on the quality of the fabric, especially the vividness of the shade of the printed cloth.

Abstract

The invention provides a disperse and reactive printing method for a polyester-cotton fabric. The method comprises the following steps: dissolved disperse dyes, dissolved reactive dyes, and a paste material are mixed to obtain a printing paste; the polyester-cotton fabric is printed through the printing paste and then dried; after being baked at high temperature, the dried polyester-cotton fabric is padded with a substitute fixation alkali liquor, and then stacked at the room temperature; the stacked polyester-cotton fabric is washed and dried to obtain disperse and reactive polyester-cotton printed fabric. According to the invention, during the disperse and reactive printing process, the printing paste contains no fixation alkaline agent, so that the stability of the printing paste is high, influences on the color development of the disperse dyes are small, the printed colors are dark, and the dye utilization rates are high. Through the alkali padding and indoor-temperature stacking of the printed and polyester-cotton baked fabric, the dyes react with the fibers under the alkaline condition and achieve adequate dyeing, so as to achieve the fixation effect; the fixation temperature is low in the fixation method, so as to improve the dye utilization rates and the dyeing depth and fastness, reduce the chromaticity of waste water and be beneficial to environmental protection.

Description

technical field [0001] The invention relates to the field of textile printing, in particular to a method for dispersing reactive printing on T / C fabrics. Background technique [0002] T / C fabric adopts disperse / reactive dye co-slurry printing process, which is accepted by many printing and dyeing manufacturers and is also one of the conventional processes in the printing and dyeing industry. It not only has the characteristics of short process flow, convenient operation, soft hand feeling, etc., but also has complete chromatograms and low cost. However, in this process, the molecular structure of many disperse dyes will change under high temperature and alkaline conditions by using urea and baking soda, which will cause the hydrolysis of some dyes and reduce the dyeing performance; and it is easy to make the fabric yellow. , The cloth surface is dark, which has a direct impact on the quality of the fabric, especially the vividness of the shade of the printed cloth. This is...
