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 an acrylate polymer emulsion containing pigment particles and a method for preparing the acrylate polymer emulsion containing pigment particles which can be directly used for textile paint dyeing. The emulsion is a colored emulsion, the middle layer and the shell layer of the latex particles are respectively modified by internal crosslinking monomers and external crosslinking monomers, and present a state of soft inside and hard outside. The colored emulsion for paint dyeing prepared by the process has no formaldehyde release during preparation and use, does not contain alkylphenol polyoxyethylene ether, has high monomer conversion rate, low residual monomer content, and good environmental safety. The colored emulsion is used for paint dyeing of fabrics, does not stick to rollers, has soft hand feeling, and has high dry and wet rubbing fastness and soaping fastness.

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 ...
