Abstract

The invention relates to a method for preparing a transfer white discharge printed fabric. The method comprises the following steps: 1, preparing white discharge ink, wherein the white discharge ink is prepared from a formaldehyde-free white discharge agent, a solubilizer, a humectant and an additive; 2, preparing dry-heat transfer printed paper; 3, printing the dry-heat transfer printed paper prepared in the step 2 through ink-jet printers of dye ink and the white discharge ink in sequence so as to obtain dry-heat transfer white discharge printed paper; 4, laminating the dry-heat transfer white discharge printed paper with a dry fabric in a hot-pressing manner, and steaming so as to fix and discharge color; and 5, peeling off the dry-heat transfer white discharge printed paper from the fabric after steaming, and washing with water, thereby obtaining the transfer white discharge printed fabric. By adopting the method provided by the invention, white discharge printing and dry-heat transfer printing are combined together, so that the characteristics that white discharge patterns are fine, vivid, rich in layer, full and bright, intense in color contrast, full in base color and the like can be greatly exerted.

Description

technical field [0001] The invention relates to a preparation method of a transfer-discharging printed fabric. Background technique [0002] White-discharging printing is printing on dyed fabrics. The printing paste contains chemical substances (called whitening agents) that can destroy dyeing dyes, and the printing method of destroying or decolorizing the ground color dyes at the printing place. The pattern of white printing has the characteristics of meticulous, lifelike, rich layers, plump and gorgeous, strong color contrast, clear outline, and full background color. Traditional white-out printing is realized by screen or paint printing, the process is cumbersome, and the amount of slurry is too large to cause water pollution, and these printing methods limit the characteristics of white-out printing to a certain extent, such as fine patterns, rich layers, and clear outlines. . [0003] In view of the above-mentioned defects, the designers are actively researching and i...
