Abstract

The invention provides a bright film printing paste for textiles. The bright film printing paste comprises the following raw materials in parts by weight: 20 to 21 parts of itaconic acid, 350 to 360 parts of butyl acrylate, 71 to 73 parts of hydroxyethyl acrylate, 10 to 10.5 parts of tripropylene glycol diacrylate, 42 to 44 parts of acrylonitrile, 2 to 2.3 parts of fatty alcohol-polyoxyethylene ether 23E9, 1.9 to 2.1 parts of ammonium persulfate, 550 to 600 parts of deionized water, and 20 to 22 parts of associated levelling rheological agent WT-203. The preparation method comprises the steps of emulsifying, initiating polymerization, and thickening, so as to obtain the bright film printing paste. The bright film printing paste is high in transparency, high in glossiness, free from yellowing at a high temperature, excellent in firmness, and soft in hand feel, and meets the environmental protection requirement.

Description

technical field [0001] The invention relates to a printing paste for textile printing, which is characterized by a bright film printing paste for direct printing on textiles. Background technique [0002] As a special printing paste, bright film printing paste is mainly used for printing decorative fabrics and clothing fabrics. Generally, bright film printing paste is printed directly on colored textiles, so as to achieve the pattern of the printed part with bright luster and film feeling and the unprinted part. The soft luster produces a strong contrast, giving people different visual effects. This requires that the bright film printing paste product used for printing has good transparency, high gloss, no yellowing at high temperature, good fastness, soft hand feeling, and meets environmental protection requirements. At present, bright film printing pastes are used in the market, such as the ET products of Italian Nimberdi Company, but the application effect is not ideal, ...
