Problems solved by technology

[0003] Acrylic adhesives are used as printing emulsion adhesives, which have the advantages of strong adhesion to pigments and fibers, good transparency, good weather resistance, and good film-forming performance, but generally have poor water resistance, It becomes brittle at low temperature, becomes sticky at high temperature, and the printing rubbing fastness is not good, and the hand feels rough.
In the swimsuit printing process, because swimsuits need to withstand long-term immersion in water during use, there are high requirements for printing fastness, water resistance, and anti-adhesion. At the same time, swimsuits are made of high-elastic special fabrics, which require printing emulsions to form films Afterwards, it has good rebound performance, but the acrylic printing emulsion in the prior art is difficult to meet the requirements

Abstract

The invention discloses a modified acrylate printing emulsion which is formed by emulsion polymerization of a monomer raw material. The monomer raw material comprises acrylate, methacrylate, vinyl acetate, acrylonitrile, acrylic acid, an organic-silicon modified monomer, a cross-linking monomer and a surface-active monomer, wherein the organic-silicon modified monomer is linear organic polysiloxane containing alkenyl bonded with silicon. The invention further provides a preparation method of the modified acrylate printing emulsion. The method utilizes acrylate and / or methacrylate and the surface-active monomer to prepare a seed emulsion, so that the dosage of an emulsifier can be reduced, polymerization is stable, and the gel content is lower. The prepared emulsion is good in water resistance and prominent in resilience. After the emulsion is used for printing, the printing color fastness and the washing fastness are good, amd the handfeel is soft.

Description

technical field [0001] The invention relates to a textile printing and dyeing auxiliary agent, in particular to a modified acrylate printing emulsion and a preparation method thereof. Background technique [0002] Pigment printing refers to the printing method that uses adhesives to fix pigments that are insoluble in water and have no affinity and reactivity to fabric fibers on fabrics, and then dry them into films to achieve coloring and form different patterns. Pigment printing has a simple process and low cost. After printing, it only needs to be dried and fixed without washing, saving water, electricity, gas, and less waste water. It has become the main method for printing patterns on various fabrics (such as bed sheets, cultural shirts, decorative cloth, etc.). method. [0003] Acrylic adhesives are used as printing emulsion adhesives, which have the advantages of strong adhesion to pigments and fibers, good transparency, good weather resistance, and good film-forming ...
