Abstract

The invention discloses a binder used for pigment printing of textiles and a preparation method thereof. The binder is prepared by seed emulsion polymerization of fatty alcohol polyoxyethylene ether sodium sulfate, diethylaminoethyl methacrylate, methacryloyloxy ethyl acetoacetate, sodium lauryl sulfate, acrylic acid, acrylic ester, ammonium persulfate and deionized water. The binder is free of formaldehyde or alkylphenol polyoxyethylene and has soft hand-feeling and good soaping fastness.

Description

technical field [0001] The invention relates to an adhesive for textile pigment printing and a preparation method thereof. Background technique [0002] Pigment printing mainly relies on the adhesive to form a film to fix the pigment on the fabric, so the quality of the adhesive is the main factor restricting the development of pigment printing. At present, most of the active groups of methylolacrylamide are contained in the adhesive composition of textile coatings, which rely on the active groups of methylolacrylamide to produce crosslinking after high temperature action, and it is inevitable to release them during use. Formaldehyde pollutes the environment and affects the environmental performance of the final product. At present, domestic and foreign standards have relatively strict restrictions on the free formaldehyde content of textiles. In Okeo-TEX Standard 100, it is stipulated that the formaldehyde content of children's clothing shall not exceed 20ppm, and the form...
