Abstract

The invention discloses a hydrolysis retardant for liquid active dye and method for making same, wherein the hydrolysis retardant for liquid active dye comprises monobasic sodium phosphate 0.05%-0.6%, disodium hydrogen phosphate 0.025%-0.3%, sodium nitrite, sodium chlorate 0.05%-0.8%, and balancing water.

Description

technical field [0001] The invention relates to an additive for liquid reactive dyes, in particular to a hydrolysis inhibitor for liquid reactive dyes and a preparation method thereof. Background technique [0002] Reactive dyes have the characteristics of complete color spectrum, bright color and good color fastness, so they are widely used in printing and dyeing of fabrics. [0003] In the printing process of reactive dyes, the main factor that affects and restricts the output and quality of reactive dye printing is the traditional reactive dye sizing process. Traditional reactive dye paste mixing, due to human factors, it is difficult to ensure the accuracy of the measurement of each component in the reactive dye printing paste, and it is difficult to ensure the quality stability of printed products. At the same time, due to the low work efficiency of the traditional reactive dye mixing process, printing machines are often encountered in production. This phenomenon also ...
