Abstract

The invention relates to a making method of a transfer discharge printing fabric.The method comprises the following steps that 1, discharge ink is prepared, wherein the discharge ink is prepared from discharge-resistant dye, a formaldehyde-free white discharging agent, a solubilizer, a humectant and additives; 2, dry heat transfer printing paper is prepared; 3, the dry heat transfer printing paper prepared in the second step is subjected to ink-jet printing sequentially through ink-jet printers containing dye-based ink and discharge ink, and dry heat transfer discharge printing paper is obtained; 4, the dry heat transfer discharge printing paper and a dry fabric are subjected to hot-pressing laminating, and steaming fixation and stripping are conducted; 5, the fabric and the dry heat transfer discharge printing paper are subjected to stripping and water washing after being steamed, and the transfer discharge printing fabric is obtained.According to the making method, discharge printing and dry heat transfer printing are combined together, and the advantages, shown by white discharging stripes, of being exquisite, vivid, rich in layering, plump, gorgeous, high in color contrast, clear in outline, full in ground color and the like are greatly exerted.

Description

Technical field [0001] The invention relates to a method for preparing transfer discharge printing fabric. Background technique [0002] Discharge printing is a printing method that prints on already dyed fabrics. The printing paste contains chemical substances that can destroy the dyes (called white discharge agents), which destroys or decolors the ground dyes in the printing area. The pattern of discharge printing is meticulous, realistic, rich in layers, plump and gorgeous, with strong color contrast, clear outline, and full background. Traditional discharge printing is realized by screen or pigment printing. The process is cumbersome and the amount of slurry is likely to cause water pollution. To a certain extent, these printing methods limit the characteristics of discharge printing with fine patterns, rich layers and clear outlines. . [0003] In view of the above-mentioned shortcomings, the designer actively researches and innovates, in order to create a simple method and ...
