Problems solved by technology

[0003] However, most of the existing composite dyes that can be used for discharge printing generally have poor compatibility between the components, because the compatibility requirements between the components of the composite dye are particularly high during the discharge printing process, otherwise it is difficult to achieve good reproducibility and whiteness

Abstract

The invention discloses a complex discharge printing disperse dye. The comprised components and their weight proportion are as follows: dye monomer (1) 1- 25%, shown in formula (I); dye monomer (2) 5- 40%, shown in formula (II); dye monomer (3) 1- 15%, shown in formula (III); dye monomer (4) 0- 10%, shown in formula (IV); and the left are adjuvant. The discharge printing disperse dye is especially suitable for printing and dyeing for terylene, artificial silk fabric, chamois flannel and corduroy. It is characterized by good reduction discharge, good printing effect of bright color, fine pattern and clear shape, possibility for printing in part area and light printing on dark cloth. The repeatability is good and thermal- resistant mobility is small.

Description

technical field [0001] The invention relates to a dye, in particular to a discharge printing disperse dye compounded from disperse dyes. technical background [0002] With the continuous improvement of pattern requirements, the outline definition and pattern fineness of direct printing are limited to a certain extent, and discharge dyes just solve this problem. The pattern printing effect of this discharge dye is much better than that of direct printing, especially it can print light-color patterns and patterns on dark fabrics, and it can also discharge printing on imitation silk fabrics. [0003] However, most of the existing composite dyes that can be used for discharge printing generally have poor compatibility between the components, because the compatibility requirements between the components of the composite dye are particularly high during the discharge printing process, otherwise it is difficult to achieve good reproducibility And whiteness.
