Environment-friendly dispersing agent for dyeing in one bath

Abstract

The invention relates to environment-friendly dispersing agent for dyeing in one bath. The dispersing agent is applicable to pure chemical fiber fabric like polyester or blended fabric containing chemical fiber like polyester cotton, polyester chinlon, polyester acrylic cotton and wool polyester acrylic fiber. The dispersing agent has more protruding advantages for bathing and dyeing the blended fabric like polyester acrylic cotton and wool polyester acrylic fiber. The environment-friendly dispersing agent is characterized by being prepared from, by mass, 5%-20% of fatty alcohol-polyoxyethylene ether, 5%-20% of plant cardanol polyoxyethylene ether, 5%-10% of adsorption dispersing agent, 0.2%-1% of emulsifying thickening dispersing agent and the balance water. The environment-friendly dispersing agent for dyeing and bathing has high dispersing force on dyestuff and a high leveling property, can effectively solve the problems like color tone and color spots and solve the precipitation problem caused when the dyestuff has different kinds of iconicity at the same time. Besides, the environment-friendly dispersing agent also has a certain oil removing capability and the capability of washing a dye vat, so that multiple fiber and multiple dyestuff are smoothly subjected to one bath, time, water and power are saved, energy conservation and emission reduction are achieved, the economiceffect is effectively improved, and the energy conservation and environmental protection requirement is better met.

Description

technical field [0001] The invention belongs to the technical field of fabric dyeing, and in particular relates to an environment-friendly dispersant for one-bath dyeing. Background technique [0002] When dyeing fibers, the corresponding dye type will be selected according to the fiber type. Generally, disperse dyes are used for polyester fibers, reactive dyes are generally used for cotton fibers, cationic dyes are generally used for acrylic fibers, and acid dyes are generally used for nylon fibers and wool. When dyeing single-fiber fabrics, if no dispersant is used, the dye will easily form a difference between the inner and outer layers of the fabric. Therefore, it is necessary to add a dispersant in the same bath to fully disperse the dye in the dyeing bath to avoid layer difference. When dyeing multi-fiber blended fabrics, the traditional dyeing process for different types of fibers requires many processes, which not only consumes dyes, time, electricity, water, and man...

AI Technical Summary

Problems solved by technology

When dyeing multi-fiber blended fabrics, the traditional dyeing process for different types of fibers requires many processes, which not only consumes dyes, time, electricity, water, and manpower, but is also prone to errors and easy to dye flowers. , a variety of dyes are added at the same time, each dye has different dyeability and dye uptake rate for different fibers, and it is easy to cause problems such as color spots, stains, and uneven dyeing. Therefore, it is also necessary to add a dispersant in the same bath during the dyeing process to avoid Such problems
