Abstract

The invention provides an environment-friendly paint discharge printing discharge paste and a discharge printing technology thereof. The environment-friendly paint discharge printing discharge paste comprises paint discharge printing white discharge paste and paint discharge printing color discharge paste: the paint discharge printing white discharge paste is a mixture formed by 100 parts by weight of discharge resistant composite thickening paste, 1.5 to 2 parts by weight of softener, 4 to 6 parts by weight of wetting penetrant and 3 to 7 parts by weigh of discharging agent, which are uniformly mixed; the paint discharge printing color discharge paste is a mixture formed by 100 parts by weight of the discharge resistant composite thickening paste, 10 to 20 parts by weight of adhesive, 1.5 to 2 parts by weight of the softener, 4 to 6 parts by weight of the wetting penetrant, 3 to 7 parts by weight of the discharging agent and 1 to 5 parts by weight of discharge resistant paint, which are uniformly mixed. By applying the discharge paste to carry out discharge printing, not only water and energy are saved and environment is protected, but also the whiteness of the white discharge printing is guaranteed to be high, the color fastness of the fabrics after the paint color discharge printing is high, and hand feeling is soft.

Description

Technical field: [0001] The invention relates to an environment-friendly discharge printing paste for paint and a discharge printing process thereof. Background technique: [0002] Discharge printing can achieve exquisite printing effects that cannot be achieved by conventional direct printing. The printed fabrics have fine patterns and clear outlines, and can avoid the problem of double color between designs and colors during the direct printing process, especially in dark colors. The effect of light-colored thin stems can be achieved on the surface, and the grade of the product is higher than that of direct printing products. At present, the commonly used dye discharge agents Diabaikuan C (sodium formaldehyde sulfoxylate), Degulin (zinc formaldehyde sulfoxylate), and Diaobai agent H (calcium formaldehyde sulfoxylate) are formaldehyde sulfoxylate reducing agents. , During production and use, free formaldehyde will be released, endangering human health and environmental pro...
