Dyeing process of textile fabric

Abstract

The invention provides a dyeing process of a textile fabric. The dyeing process comprises the following steps: 1, putting the textile fabric into a high-pressure dye vat; after injecting water into the high-pressure dye vat, injecting steam; 2, when the temprature of the water in the high-pressure dye vat is raised to 80 DEG C to 100 DEG C, adding a scouring agent into the high-pressure dye vat and stirring a solution; meanwhile, adding an alkaline solution and regulating the pH (Potential of Hydrogen) value; carrying out sealing treatment; 3, raising the pressure and temperature in the high-pressure dye vat; 4, keeping the pressure and temperature in the high-pressure dye vat and continually scouring; 5, after finishing scouring, reducing the pressure and temperature in the high-pressure dye vat to normal temperature and normal pressure; then draining the solution in the high-pressure dye vat; 6, carrying out water washing treatment on the textile fabric obtained by step 5 under normal temperature and normal pressure conditions; 7, putting the textile fabric washed with the water in step 6 into the dye vat and carrying out dyeing treatment. According to the dyeing process of the textile fabric, the dyeing effect of the textile fabric is excellent; the method is simple and convenient to operate, the dyeing is rapid and the coloring time is short, so that the dyeing process of the textile fabric is suitable for industrial and large-batch production.

Description

technical field [0001] The invention belongs to the technical field of dyeing process, in particular to a dyeing process of textile cloth. Background technique [0002] The printing process in which the color paste is directly printed on white or light-colored fabrics, and then steamed and other post-treatments is called printing. The types of printing include direct dye printing, reactive dye direct printing, vat dye direct printing, temporary vat dye direct printing, insoluble azo dye direct printing, aniline black direct printing, disperse dye direct printing and fast pigment, fast amine, fast sulfonate Plain dye direct printing. [0003] A large number of chemical dyes are used in the textile printing and dyeing industry, which has a serious impact on the environment. Currently commonly used synthetic dyes contain carcinogenic substances, which directly harm the wearer or the producer, and are irritating and allergic to the skin. In order to prevent the aggravation of...

Problems solved by technology

However, since the main raw material for the preparation of sodium alginate is kelp, not only the resources are limited, but also the cost is high. In order to promote the development of the printing and dyeing industry, it is necessary to develop a new dyeing method to improve the deficiencies of the existing technology and make cheap Dyes also give great staining results
