Abstract

The invention relates to the technical field of textile printing and dyeing, and provides a low-temperature soaping agent for a cellulose reactive dye. The low-temperature soaping agent is prepared bycompounding a Gemini anionic sulfonate surfactant, polymer and other auxiliary agents, and comprises the following components in percentages by weight: 1-20% of sodium dialkyl diphenyl ether disulfonate, 5-15% of anionic surfactant AOT, 0.1-0.5% of a defoaming agent, 0.1-5% of beta-cyclodextrin, 0.2-2% of sodium polyacrylate, 1-10% of polyvinylpyrrolidone and the balance of deionized water. The soaping agent has the advantages of low foam, strong hard water resistance, remarkable color removal effect in low-temperature soaping at the temperature of 60 DEG C, energy conservation, emission reduction and production cost reduction, and has positive significance for improving the problem of high energy consumption in the printing and dyeing industry.

Description

technical field

[0001] The invention relates to the technical field of printing and dyeing of textile materials, in particular to a low-temperature soaping agent for cellulose reactive dyes and its application. Background technique

[0002] Reactive dyes are bright in color and complete in color spectrum, have high reactivity and level dyeing ability, are relatively stable in hard water environment and low in cost, so most of the cellulose fibers are printed and dyed with reactive dyes. Reactive dye molecules are highly water-soluble and often cannot react completely, so a certain amount of free dye that has not formed a covalent bond will remain after dyeing. In addition, the dye that has been fixed on the fiber may be partially hydrolyzed, that is, the active group of the reactive dye is replaced by a hydroxyl group to form a hydrolyzed dye. As a result, the fibers printed and dyed with reactive dyes tend to have a low color fixation rate, and are prone to bleeding and re...
