Abstract

The invention discloses reactive dye for cotton fiber. The reactive dye is prepared from 75-85% of hydroxypropyl methyl cellulose, 5-8% of dilauryl thiodipropionate, 6-10% of polyacrylamide, 2-3% of alkylphenol polyoxyethylene ester, and 2-4% of titanium dioxide powder. The production method comprises the steps: sequentially primarily treating, drying and grinding the hydroxypropyl methyl cellulose to prepare particulate matters, wherein the hydroxypropyl methyl cellulose is prepared after secondary reaction; then, uniformly mixing the dilauryl thiodipropionate, the polyacrylamide, the alkylphenol polyoxyethylene ester and the like, and treating to obtain a liquid material; and adding the hydroxypropyl methyl cellulose and other raw materials into a material mixer, and stirring and mixing uniformly to obtain the reactive dye. The reactive dye has the advantages of simple processing technology, low price and high dyeing degree.

Description

technical field [0001] The invention relates to a textile dye, in particular to a cotton fiber reactive dye and a production method thereof. Background technique [0002] Reactive dyes, also known as reactive dyes. It is a class of dyes that chemically react with fibers during dyeing. Such dye molecules contain groups that can chemically react with fibers. When dyeing, the dyes react with the fibers, and form covalent bonds between the two to form a whole, which improves the fastness to washing and rubbing. However, due to the high price and limited raw material resources, it cannot meet the needs of the printing and dyeing industry. Contents of the invention [0003] The invention provides a cotton fiber reactive dye. [0004] A cotton fiber reactive dye printing paste, which uses light hydroxypropyl methylcellulose as the main raw material, and also includes: sodium polyacrylate, polyacrylamide, alkylphenol polyoxyethylene ester, titanium dioxide powder, etc. The wei...
