Abstract

The invention provides a bi-component water-borne printing binder, and a preparation method and application thereof. The bi-component water-borne printing binder comprises a component A and a component B. The component A comprises, by weight, 30-70 parts of hydroxyl-containing resin emulsion, 0.5-2.5 parts of wetting dispersant, 0.2-2 parts of thickening agent, 0.2-1 part of defoaming agent, 5-20parts of water, and 0.2-2 parts of complex solubilizer. The component B comprises a water-borne polyurethane curing agent. The bi-component water-borne printing binder has excellent water resistance,adhesion force and fastness and can also give better hand feeling and comfortability to jean fabrics.

Description

technical field [0001] The invention belongs to the technical field of apparel processing, and in particular relates to a two-component water-based printing glue and its preparation method and application. Background technique [0002] Water-based denim printing paste is a paste composed of resin, curing agent, powder, additives, etc., using water as the dispersion medium. It is a green and environmentally friendly paste that is printed on denim through screen printing to obtain rich colors. , three-dimensional strong pattern. Generally speaking, water-based denim slurry can be divided into one-component and two-component. One-component is to directly print the paste on the cloth, which has the advantages of easy operation and high efficiency. Two-component products can form a cross-linked network structure between the resin and the curing agent, so their water resistance, adhesion, tensile strength and other properties will be stronger than those of one-component products...
