Abstract

The invention relates to three-dimensional printing paste. The three-dimensional printing paste is composed of, by mass, 10-40 parts of polyethylene glycol 200 diacrylate, 100-500 parts of polymethyl acrylate, 10-50 parts of trimethylolpropane, 5-30 parts of polysiloxane, 15-80 parts of N-(isobutoxymethyl)acrylamide, 5-50 parts of vinyl acetate, 4-60 parts of sodium hexametaphosphate, 150-300 parts of sodium alginate, 5-30 parts of sodium carbonate, 5-10 parts of starch, 3-10 parts of chain extenders and 0.2-0.6 part of a catalyst. The chain extenders are one or more of ethidene diamine, 1,4-butanediol and ethanediol. The catalyst is dibutyltin dilaurate or dibutyl tin acetate. After the three-dimensional printing paste prepared through the formula and the technical method is printed on cloth through baking setting during flat screen printing or rotary screen printing, obtained patterns have convex-concave feeling, bright colors and a sharp contrast.

Description

technical field [0001] The invention relates to a three-dimensional printing paste, which belongs to the technical field of textile printing. Background technique [0002] Textile printing is a process of limited dyeing on a predetermined area of ​​the fabric, including the preparation of color paste, development and color fixation, and the addition of thickeners to limit the color paste to the predetermined range of the fabric. Textile printing is generally based on dyes, especially on silk fabrics, it is necessary to use corresponding dyes according to different fiber properties. The technical process and supporting equipment are relatively complicated. Pigment printing paste is used as printing material for printing, which is called "water-based ink". Due to the need for practicality, the color of textile screen printing must have a certain degree of fastness (not easy to fade), and its color changes greatly, so the size and color should be sold and stored separately, an...
