Environment-friendly low temperature soaping agent

Abstract

The invention discloses an environment-friendly low temperature soaping agent. The environment-friendly low temperature soaping agent is prepared from, by mass, 30-50 parts of maleic anhydride-acrylic acid-ethoxy methylene malonic diethyl ester terpolymer solution, 10-30 parts of carboxyethyl thiosuccinic acid, 0.5-5 parts of ethydiaminedhephen acetic-Na, 5-10 parts of mineral clay and 30-50 parts of water. The environment-friendly low temperature soaping agent is a gray translucent liquid, does not contain phosphorus and nitrogen and is environmentally friendly and efficient, and the soaping temperature can reach 40 DEG C to 60 DEG C; the environment-friendly low temperature soaping agent is used for soaping and acts on cotton and blended fabric thereof which are subjected to dyeing with reactive dyes and printing, the anti-staining capacity is high, and the surface dyeing removing effect is significant; after the low temperature soaping agent is used for soaping of reactive dyes, the COD value of soaping wastewater is low, the treatment cost of subsequent wastewater is reduced, and the environment-friendly low temperature soaping agent is stable in property in hard water and has an obvious market advantage.

Description

1. Technical field [0001] The invention relates to an environment-friendly low-temperature soaping agent, which is used for the dyeing of cotton and its blended fabrics with reactive dyes in the textile dyeing and finishing industry and the soaping treatment process after printing, and belongs to the field of fine chemicals. 2. Background technology [0002] Cotton, linen, viscose, tencel and other fibers and their blended fabrics must be soaped after dyeing and printing. The main purpose of soaping is to remove hydrolyzed dyes, unfixed dyes and other impurities adhering to the fibers. In the traditional market, some phosphorus-nitrogen-containing and surfactant-based soaping agents are often used, causing serious eutrophication to the environment. [0003] In recent years, acidic soaping agents produced by the copolymerization of monomers such as acrylic acid and maleic anhydride have appeared in China. Since this soaping agent has no foam, the soaping agent has a good effe...

Problems solved by technology

[0006] Based on various modified methacrylic resins, it was found that the methoxymethylenemalonate diethyl ester (EMME) modified methacrylic resin was combined with soaping agent compounded with other surfactants The effect is better, and the strong adsorption of mineral clay can be applied to the de-floating of textiles, the effect is more obvious, and there is no report in various documents
