Problems solved by technology

With the rapid development of science and technology, the composition and organizational structure of textiles are also changing rapidly, especially more and more blended, interwoven and composite textiles of various fibers, which requires higher and higher requirements for dyeing agents. In the technology, the dyed fabric will fade more obviously during the long-term washing and sun exposure process, the dyeing is not firm, and it cannot meet people's requirements for color.
However, most of the existing dyes on the market do not have enough affinity. Under high temperature and acid-base environment, they cause poor level dyeing and are prone to fading.

Abstract

The invention discloses chitosan added textile dye and a preparation method thereof. The textile dye is prepared from the following raw materials in parts by weight: 30-50 parts of a natural dye raw material, 1-3 parts of an organic dying raw material, 10-15 parts of chitosan, 1-5 parts of ethylcellulose, 2-4 parts of sodium dodecyl sulfate, 4-8 parts of diethanolamine, 1-4 parts of malic acid, 4-7 parts of aluminum potassium sulfate dodecahydrate, 1-3 parts of polyvinylpyrrolidone, 4-8 parts of polyoxyethylene octylphenol ether, 1-2 parts of amylopectin, 1-3 parts of dibutyltin dilaurate, 3-6 parts of iron oxide red, 1-3 parts of sulfonated oil, 1-4 parts of soap powder, 2-5 parts of oxalic acid, 2-5 parts of a coupling agent and 1-4 parts of an aid. The prepared chitosan added textile dye is good in printing and dyeing effect and is friendly and damage-free to fabric. The invention further discloses the preparation method of the chitosan added textile dye.

Description

technical field [0001] The invention relates to the field of dyeing agents, in particular to a chitosan-added textile dye and a preparation method thereof. Background technique [0002] Dye is a substance that can make a certain color adhere to the fiber, and it is not easy to fall off and change color. Dyes are usually soluble in water, and some dyes require a mordant to make the dye stick to the fiber. The color of the dye and its affinity with the tissue are determined by the molecular structure of the dye itself. The chromophore that produces the color and the auxochrome that produces the affinity with the tissue together determine the dyeing properties of the dye. With the rapid development of science and technology, the composition and organizational structure of textiles are also changing rapidly, especially more and more blended, interwoven and composite textiles of various fibers, which requires higher and higher requirements for dyeing agents. In the technology, ...
