Abstract

Disclosed are a cold transferring printing thickener and preparation method of color paste thereof. The said thickener comprises oxidized starch, printing oil and etherified starch. The cold transferring printing thickener can be dissolved in the water quickly. When the thickener is contacted with the textile treated with pre-treating liquid in the cold transferring printing process, it can carry dyes promptly and be transferred onto the surface of the textile. The film formed by drying the color paste made of the said thickener has good elasticity, so cracks of the printed pattern and clogging of the mesh or network hole can be effectively avoided.

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 cold transfer printing paste is used as the carrier of the dye, and the printing paste prepared by 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. Combined, the dye is separated or peeled off from the paper base by pressure, and the patte...
