Problems solved by technology

Raw cotton yarn contains more natural impurities, mainly pectin, wax, ash and pigment, etc. Insufficient refining is not good for dyeing
Moreover, the traditional reactive dyeing process is low-temperature dyeing at 60 degrees, and some soda ash is pre-added before feeding, which is not conducive to dye migration, so the strands cannot be dyed through and will be exposed to white

Abstract

The invention discloses a dyeing process of a chinlon and cotton lace. The dyeing process of the chinlon and cotton lace is mainly characterized in that a cotton pretreatment process, PH before activedyeing, a high-temperature migration temperature and time and soda ash adding time are controlled, the using amount of an auxiliary is selected, and the temperature of a dyeing bath and temperature keeping time are selected, so that a reasonable dyeing process is optimized, the problem of exposure of coarse folded yarns of the chinlon and cotton lace is solved, and a new idea and a new directionare provided for the type of products. According to the dyeing process of the chinlon and cotton lace, tea saponin, flake alkali, hydrogen peroxide and a refining agent are used for improving the wooleffect of cotton in a pretreatment process of cotton, so that the permeability of reactive dyes is enhanced. By adopting the dyeing process of the chinlon and cotton lace, the active dyeing temperature is raised to 95 to 98 DEG C, and the dye diffusion time is prolonged. After high-temperature migration, the temperature is lowered and soda ash is added fractionally to fix the dyes, so that migration of the dyes is facilitated, the permeability of the dyes is enhanced, and the problem of folded yarn exposure during dyeing is solved; moreover, high-temperature migration under a neutral PH condition does not cause hydrolysis of the reactive dyes, so that the color depth does not decline.

Description

technical field [0001] The invention relates to a cloth dyeing process, in particular to a brocade cotton edge dyeing process. Background technique [0002] At present, brocade cotton edge is very popular in the clothing market, mainly for high-end dresses and suits made of body fabrics. However, due to the variety of materials used in this type of product and the tight weaving structure, subsequent dyeing is not easy to dye, and the cotton strands are easy to be dyed imperviously with the normal reactive dyeing process, resulting in whitening of the cross-section when making garments or causing strands due to friction during wearing. Thread exposure and whitening and other problems, thus affecting the aesthetic performance of clothing. At the same time, the brocade cotton edge fabric contains a large amount of cotton yarn, and the thick strand product is rayon outsourcing natural cotton strand. Raw cotton yarn contains more natural impurities, mainly pectin, wax, ash an...
