Abstract

The invention discloses a cotton reactive dye cleaning agent. The cotton reactive dye cleaning agent is prepared from components in parts by mass as follows: 25-50 parts of a styrene-maleic acid copolymer alkali hydrolysate, 30-60 parts of alkaline lignosulfonate, 5-20 parts of an ethylene vinyl pyrrolidone-imidazoline copolymer, 2-6 parts of an N-[4-(trimethylamine methyl)benzoyl]caprolactam chloride and 10-40 parts of an acrylic acid-2-acrylamide-2-methacrylic acid copolymer alkali hydrolysate. The cotton reactive dye cleaning agent requires low soaping temperature and few soaping times and has excellent soaping fastness and rubbing fastness.

Description

technical field [0001] The invention relates to a processing aid for cotton textiles, in particular to a cleaning agent for cotton reactive dyes and a preparation method thereof. Background technique [0002] Reactive dyes are currently widely used textile processing aids, which use reactive groups in dyes to chemically react with textile fibers, and dye particles are connected to fiber molecular chains in the form of covalent bonds to improve the dye’s Washing and rubbing fastness on textile fibers. However, during the entire printing and dyeing process, some dye particles failed to fully react with the fibers and were only adsorbed on the fibers. Especially for cotton textiles, the ambient temperature requirement for the covalent linking reaction between dye particles and cotton fibers is relatively high, and the chemical reaction is easily affected by the previous treatment process, so cotton textiles usually need to be soaped after printing and dyeing , to enhance the ...
