Vegetable reactive dye printing paste and production method thereof

Abstract

The invention relates to vegetable reactive dye printing paste comprising 80-90 percent of lightly-crosslinked ultra-high-viscosity high-substitution-value carboxymethyl starch, 3-6 percent of sodium polyacrylate, 5-9 percent of polyacrylamide, 1-2.5 percent of fatty alcohol polyethenoxy ether, 1-2.5 percent of solid lanthanon powders and the like. The vegetable reactive dye printing paste is produced according to the following process: the carboxymethyl starch prepared after secondary reaction is carried out the coarsely crushed, dried and finely crushed to be made into fine particle materials of granularity under 40 meshes; then the liquid material prepared from the sodium polyacrylate, the polyacrylamide, the fatty alcohol polyethenoxy ether and the like which are uniformly mixed is processed into solid materials by a high-speed centrifugation atomization drying device, and finally the carboxymethyl starch and other raw materials are added into a material mixer to be stirred and mixed uniformly according to the production formula of printing paste and enters into an automatic packaging machine to be packed into product. The printing paste has superior printing performance to sodium alginate, has simple processing technology and low cost and is the optimal substitute of the sodium alginate printing paste.

Description

technical field

[0001] The invention relates to a textile printing and dyeing auxiliary agent, in particular to a plant reactive dye printing paste. Background technique

[0002] For a long time, sodium alginate has been the only good thickener for reactive dye printing, but due to its high price and limited raw material resources, it cannot meet the needs of the printing and dyeing industry. In order to seek substitutes for sodium alginate, many countries in the world, especially the former Soviet Union, Japan, the United States, Britain, India, Egypt and other countries have done a lot of research, and some people in China have tried it, but they have not achieved the expected results. Contents of the invention

[0003] The invention provides a plant reactive dye printing paste which is better than sodium alginate in printing performance and has simple processing technology and low price and is the best substitute of sodium alginate and a production method.
