Soaping agent and method for preparing same

Abstract

The invention discloses a soaping agent and a method for preparing the same. The soaping agent comprises, by weight, 20-30 parts of maleic anhydride-polypropylene copolymers, 5-7 parts of ammonium persulfate, 5-10 parts of sodium lignin sulfonate, 5-10 parts of sodium bicarbonate, 3-5 parts of polymethylhydrosiloxane, 5-10 parts of ammonium chloride, 3-5 parts of chitosan, 3-5 parts of triolein, 5-10 parts of plant powder, 10-20 parts of ethyl alcohol, 3-5 parts of triethanolamine and 30-50 parts of deionized water. The soaping agent and the method have the advantages that the soaping agent isused for removing reactive dye which is not fixed, and the soaping temperatures can be lowered; processes for manufacturing the soaping agent are simple and are easy to implement, raw materials for the soaping agent are low in cost and are easily available, and the soaping agent is non-toxic and harmless and is free of irritation on human bodies and low in volatility.

Description

technical field [0001] The invention belongs to the technical field of textile auxiliaries, and more specifically relates to a soaping agent and a preparation method thereof. Background technique [0002] Soaping mainly refers to the post-printing and dyeing process. After the fiber fabric is printed and dyed, in order to improve its color fastness and brilliance, soap or detergent solution is used to remove unfixed dyes, dyeing auxiliaries, The processing technology of printing paste and so on under the condition of near boiling. [0003] Reactive dyes have complete color spectrum, bright color, low cost and mature dyeing process. Therefore, more than 80% of cellulose fibers are dyed and printed with reactive dyes. There are many kinds of reactive dyes with various chemical structures and different reaction efficiencies, but none of them can fully react with cellulose fibers. In addition, while dyeing and fixing fibers, the dyes will also undergo hydrolysis, that is, the r...
