Abstract

The invention provides a dyeing formula for enhancing the color fastness of a dark cashmere product. A dye is prepared from 1owf% of abegnoli B, 2owf% of low-temperature auxiliary XT, 2owf% of low-temperature auxiliary MiralanLTD and 4owf% of dye, and a bath ratio is 1:10. Compared with the prior art, the dyeing formula has the advantages that auxiliary adding and microwave pretreatment are combined, so that the color fastness and the coloring rate of the product are effectively improved; the abegnoli B and the dye are matched to enhance the dissolving property of the dye and the levelling property of cashmere fibers. A chemical method and a physical method are effectively combined, so that the color fastness and the coloring rate of the product are greatly improved; furthermore, by adding of the auxiliaries, the using amount of the dye is reduced, and the whole dyeing process is environmentally friendly.

Description

technical field [0001] The invention relates to a dyeing formula and process for improving the color fastness of dark cashmere products. Background technique [0002] The so-called dyeing is the process of dyeing fiber fabrics with dyes in a certain way. Dye dyeing fiber can generally be divided into three processes: (1) adsorption process: the dye diffuses from the dye solution to the fiber surface, and dyes the fiber surface; (2) diffusion process: the dye adsorbed on the fiber surface diffuses into the fiber, Until the dyeing is balanced or basically balanced; (3) The chemical reaction between the dye and the fiber is fixed on the fiber. Among them, the adsorption and diffusion of dyes mainly depend on the structure and performance of dyes and fiber surfaces, which are affected by many factors, including equipment, dyes and dyeing auxiliaries, dyeing process (including pH value, temperature, heating rate, heat preservation Time, etc.) and fiber performance, if the above...
