A kind of textile dye and its preparation method and water-free dyeing method

Abstract

The invention belongs to the technical field of textile waterless dyeing and specifically discloses a textile dye as well as a preparation method and a waterless dyeing method of the textile dye. Thetextile dye is mainly prepared from the following components in parts by weight: 1-10 parts of toner, 3-30 parts of organic solvent, 3-5 parts of triethylene glycol, 2-4 parts of glycerin, 0.5-5 partsof sodium lignin sulfonate, 2-5 parts of sodium metanitrobenzene sulfonate, 1-10 parts of ammonium polyacryloyldimethyl taurate, 1-10 parts of triethanolamine alginate, 0.01-0.5 part of sodium bicarbonate, 1-2 parts of hexadecylpyridinium chloride, 0.5-1 part of coco-dimethylammonium diethyl sulfate and 50-90 parts of deionized water. According to the dye prepared by the invention and the waterless dyeing method, the dyeing effect is good; moreover, washing is not needed, thus any wastewater is not generated, environmental protection is facilitated, and the production cost is lowered.

Description

[0001] field of invention [0002] The invention belongs to the technical field of anhydrous dyeing of textiles, and in particular relates to a textile dye, a preparation method thereof and an anhydrous dyeing method. Background technique [0003] Water is the source of life and the basic liquid that sustains life. The total amount of global water resources is 1.4 billion cubic kilometers, of which fresh water accounts for 2.5%, but less than 1% of the fresh water on the earth or about 0.007% of the water can be directly used by humans, and China's per capita fresh water resources only account for the world's per capita fresh water a quarter of the resource. [0004] The traditional textile dyeing technology uses water as the carrier, and through the action of heating and auxiliary agents, dyes and textiles are combined to achieve the purpose of textile dyeing. After dyeing, the textile needs to be washed in order to remove floating colors and auxiliary agents. A considerab...

Problems solved by technology

[0008] Although the anhydrous dyeing process of organic solvent dyes has been tried as early as the 1970s and 1980s, there is still no relatively mature organic solvent dyes and their anhydrous dyeing processes that are worthy of promotion and application in the industry.

The reasons for this situation lie in the following aspects: First, the volatility of the organic solvent itself can easily cause photochemical gas pollution, so its application is limited; second, the dye components have low composition stability in the organic solvent environment, and are prone to hydrolysis and failure; The third is that it is difficult to add alkaline water-soluble additives in the anhydrous dyeing process, the covalent combination of dye components and textile cellulose in the environment of organic solvents is unstable, and the swelling and damage caused by the organic solvent itself to the crystallization of textile fibers Insufficient, the penetration of dye components into fibers is not strong, resulting in relatively poor color fastness and color fixation rate, and low dyeing success rate
