Problems solved by technology

The disadvantage is that the color yield of reactive dyes is not high, the printing fixation rate of dyes can only reach 70-80%, and about 20-30% of dyes cannot be fixed on cellulose. These dyes must be removed by a large amount of soaping and washing. Otherwise, the color fastness will not meet the requirements, resulting in high water consumption for soaping; at the same time, the color of the lotion is dark, the color concentration is high, and the burden of sewage treatment is heavy; the dyes in the lotion will re-contaminate the fabric, resulting in dull and white color of the product. The bottom is not white

Abstract

The invention relates to a whole fixation printing method for the graft modification of textiles, and aims at providing the whole fixation printing method that can promote the dye fixation rate from 70 percent to 80 percent to more than 90 percent to 98 percent. The technical proposal is as follows: 1) the pretreatment of a textile, the textile is treated according to the processes of desizing, boiling, smelting and bleaching; 2) the preparation of the graft modification working fluid, the working fluid comprises 0.1 percent to 10 percent of cationic graft agent, 0.1 percent to 20 percent of alkali agent and 0 percent to 1 percent of penetrating agent, and the rest is water; 3) the treatment of the graft modification, the pretreated textile is put into a dyeing machine, and the graft modification working fluid is added; or the pretreated textile is padded with the graft modification working fluid in a padder; the printing formula of the invention comprises 50 grams of protoplasm, 2 grams to 5 grams of urea, 0.5 gram to 8 grams of dye, 1 gram to 2.5 grams of sodium bicarbonate and 0.5 gram to 1.5 grams of reserve salt, and the rest amount of water in every 100 grams according to weight; and 4) the printing technology, the printing is carried out according to the conventional technology. The whole fixation printing method for the graft modification of the textiles is used in the whole fixation printing.

Description

technical field [0001] The invention relates to a full-fix printing method of fabric graft modification, especially after the fabric has been grafted and modified for printing, the dye fixation rate is increased from 70-80% to over 90-98%, reaching full solid The purpose of color printing. Background technique [0002] Reactive dye printing products are bright in color, soft to the touch, hydrophilic and breathable, high-grade products, and are important high-grade ecological printing fabrics. The disadvantage is that the color yield of reactive dyes is not high, the printing fixation rate of dyes can only reach 70-80%, and about 20-30% of dyes cannot be fixed on cellulose. These dyes must be removed by a large amount of soaping and washing. Otherwise, the color fastness will not meet the requirements, resulting in high water consumption for soaping; at the same time, the color of the lotion is dark, the color concentration is high, and the burden of sewage treatment is hea...
