Problems solved by technology

[0004] However, the current paint dyeing process generally involves physical blending of the binder and the paint color paste, and then padding and baking of the textiles, often due to the desorption of the pigment dispersant on the surface of the color paste, and the binder in the film-forming process. Due to the low encapsulation efficiency of the pigment, the wet and dry rubbing fastness and soaping fastness of the paint-dyed fabric are low, and it is difficult to meet the requirements of the textile paint dyeing process in terms of non-stick rollers, fabric feel and environmental safety.

Abstract

The invention discloses acrylate polymer emulsion containing pigment particles and a method for preparing pigment-particle-containing acrylate polymer emulsion which can be directly applied to textile pigment dyeing. The acrylate polymer emulsion is colored emulsion, and middle-layer and shell-layer acrylate polymers of latex particles are respectively modified by an internal crosslinking monomer and an external crosslinking monomer and are in a state that the inside is soft and the outside is hard. The colored emulsion, prepared by adopting the technology, for the pigment dyeing releases no formaldehyde in preparation and using processes, does not contain alkyl phenol polyoxyethylene ether and is high in monomer conversion rate, low in residual monomer content and good in environmental safety. The colored emulsion does not stick a roller when being used for the pigment dyeing of a fabric, the handfeel of the fabric is soft, and dry and wet rubbing fastness and soaping fastness are relatively high.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing, and in particular provides an acrylate polymer emulsion containing pigment particles that can be directly used for textile paint dyeing and a preparation method thereof. Background technique [0002] Pigment dyeing is a special textile dyeing process in which pigment preparations such as water-based pigment pastes are fixed on fabrics by means of adhesives, penetrants and other substances. Compared with conventional dye dyeing, paint dyeing has become one of the new technologies in the dyeing field that has attracted widespread attention due to its advantages such as simple process, no need for washing, and almost no sewage discharge. In the dye solution used for paint dyeing, the pigment particles themselves have no affinity for the fibers, so in order to fix the pigment particles on the surface of the fibers, an adhesive must be used. The binder plays a very important role ...
