Problems solved by technology

In fact, the presence of a small amount of formaldehyde does not make the environmental protection performance of the product substandard, and ordinary adhesives containing the cross-linking monomer N-methylolacrylamide cannot control the formaldehyde content of the final product, so that the formaldehyde of the product exceeds the standard
At present, there are formaldehyde-free adhesives on the market. Generally, acetoacetate ethyl methacrylate, diacetone acrylamide, adipic acid dihydrazide, etc. are used instead of traditional N-methylol acrylamide. Although the environmental performance is better, However, due to the pursuit of absolute formaldehyde-free, some fastness indicators are sacrificed, especially the soaping fastness, which is far from ordinary formaldehyde-containing adhesives.

Abstract

The invention relates to a low-formaldehyde soaping-resistant adhesive for textile pigment printing and a preparation method thereof. The low-formaldehyde soaping-resistant adhesive is prepared from polyethylene glycol methacrylate, N-butoxy methacrylamide, acetoacetic acid ethyl methacrylate, sodium lauryl sulfate, acrylic acid, styrene, acrylate, ammonium persulfate and deionized water through emulsion polymerization. The content of free formaldehyde can be lower than 20 ppm; and the low-formaldehyde soaping-resistant adhesive has the advantages of soft feeling and high fastness soaping fastness.

Description

technical field [0001] The invention relates to a low-formaldehyde soaping-resistant 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 sh...
