Abstract

The invention discloses a light-cured compound colour paste composition for pigment printing, a preparation method and a processing method, relating to the technical field of textile dyeing and printing. The composition comprises acrylate copolymer, terminated epoxyl siloxane, an epoxyl siloxane hybrid, a photoinitiator and an organic pigment. The preparation method and the processing method comprise the following steps: adding acrylate copolymer into a container; then, sequentially adding terminated epoxyl siloxane, the epoxyl siloxane hybrid, the photoinitiator and the organic pigment and sufficiently stirring, wherein each reaction raw material is uniformly stirred after being added; and processing a fabric with the prepared composition, and then, performing crosslinking fixation for 1 minute under the conditions of 300 W / cm of ultraviolet intensity and 16 cm at height. The composition disclosed by the invention is used for pigment printing, the fabric processed by the composition is soft in hand feeling, high in wear resistance and fastness to washing and resistant to water, and the composition is good in colour paste stability and high in curing speed and can be widely applied to fabric dyeing and printing.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing, in particular to a photocurable composite pigment printing paste composition, a preparation method and a treatment method. Background technique [0002] Pigment printing is a printing process that uses adhesives to adhere color paste paint to fabrics and endow fabrics with various patterns. Traditional adhesives need to be baked to fix the paint on the fabric. This method usually takes a long time and consumes a lot of energy, which is easy to cause network plugging. With the rapid development of light-curing technology industry with advantages such as high efficiency and low energy consumption, related products of light-curing adhesives have attracted more and more attention from product developers. In addition, the color paste for fabric pigment printing is very important to the quality of printing and the improvement of fabric grade. If the photocuring technology is intro...
