Abstract

The invention discloses a method for preparing a water-based UV (Ultraviolet) pigment printing paste for textile use and belongs to the textile dyeing and finishing technical field. Oil-in-water type urethane acrylate emulsion is prepared by the external emulsion method and the ultrasonic-assisted method. A water-based pigment printing paste is prepared by adding a water-based dispersant by the grinder grinding method; and next, the paste is added to the urethane acrylate emulsion, and then an initiator and a thickener are added, thereby preparing the water-based UV pigment printing paste for textile use. The prepared water-based UV pigment printing paste has the characteristics of energy conservation, environmental protection and short process flow.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, and in particular relates to a preparation method of textile water-based UV paint printing paste. Background technique [0002] Due to the bright colors, good fastness and strong adaptability to textiles, textile pigment printing has gradually increased its share in textile printing. However, pigment printing usually uses steaming or baking to fix the color, and the color fixing process consumes a lot of energy. UV pigment printing refers to that through ultraviolet light irradiation, the initiator generates free radicals to initiate cross-linking and curing of oligomers, so that the paint is fixed on the fabric. UV paint color paste saves energy, does not contain volatile organic solvents, has fast curing speed, and saves space on site. Due to the high solid content of UV paint color paste, its viscosity is high, the curing is incomplete, and the fabric has poor hand feelin...
