Abstract

The invention belongs to the field of fine chemistry, and more specifically relates to a high-efficiency environment-friendly acidic soap washing agent, and a preparation method thereof. The high-efficiency environment-friendly acidic soap washing agent comprises, by mass, 10 to 30 parts of carboxyalkylthiosuccinic acid, 30 to 50 parts of acrylic acid-2-acrylamido-2-methyl propyl sulfonic acid (AA / AMPS) copolymer 20 to 50 parts of sodium gluconate, 5 to 10 parts of hydrolytic polymaleic anhydride, 0.1 to 2 parts of a surfactant, 0.5 to 10 parts of a complexing agent, and 30 to 50 parts of water. When the high-efficiency environment-friendly acidic soap washing agent is used in cotton and cotton blended fabric reactive dye dying, surface dyeing removing effect is better, and fabric color fastness and brightness are ensured; the high-efficiency environment-friendly acidic soap washing agent contains no nitrogen and phosphorus, and is relatively high in acidity, so that the acid neutralizing process before common soaping can be avoided, waste discharge amount is reduced, human labor is saved, electricity cost is reduced, and better market advantages are achieved.

Description

technical field [0001] The invention belongs to the field of fine chemicals, and in particular relates to an efficient and environment-friendly acid soaping agent and a preparation method thereof. Background technique [0002] A common problem in the textile dyeing and finishing industry is the problem of incomplete dyeing and low color fastness of subsequent fabrics during the dyeing and color fixing process. Therefore, after dyeing, the fabric needs to be washed with a large amount of water and soaped to remove floating colors. , Improve the color fastness of the fabric to meet the needs of customers. [0003] Traditional soaping agents mostly use phosphorus and nitrogen-containing substances, which cause serious eutrophication to the environment; conventional soaping processes mainly use neutral soaping agents, and a large amount of water washing and pickling must be selected before soaping to reduce the concentration of the working fluid in the soaping process. PH, to r...
