Abstract

The invention discloses a preparation method of cold migration printing gum and color paste thereof. The gum contains starch oxide, printing oil and etherified starch. The cold migration printing gum has high water dissolving speed, and can be used for rapidly carrying a dye and transferring onto the surface of a fabric by being contacted with the fabric treated with a pretreatment liquid in the cold migration printing process. A film formed by drying color paste prepared from the gum has high elasticity, printing patterns can be effectively prevented from cracking, and meshes and ink cells are prevented from being blocked.

Description

technical field [0001] The invention relates to a printing paste used in the textile industry, in particular to a preparation method of a cold-transfer printing paste and its color paste. The paste for cold transfer printing is used as the carrier of the dye, and the printing paste prepared into reactive dyes or acid dyes can be printed on the cold transfer printing medium, and the printing pattern is transferred from the medium to the cotton during the transfer printing process. , nylon and other textile fabrics. Background technique [0002] Printing paste refers to a polymer compound that can thicken the printing paste. The cold transfer printing process first prints the printing paste composed of paste and dye on the paper base to form a transfer printing paper with the desired pattern or text, and then the side of the transfer printing paper with the dye on it and the printed fabric closely. Combined, the dye is separated or peeled off from the paper base by pressure,...
