Problems solved by technology

The title is "Formaldehyde-free Low-Temperature Adhesive", which discloses a synthesis method of an aldehyde-free low-temperature self-crosslinking pigment printing adhesive. The aldehyde-free crosslinking monomer glycidyl methacrylate is used instead of the traditional crosslinking monomer N-methylol acrylamide makes the dry and wet rubbing fastness of printed fabrics meet the national standard. This adhesive is suitable for printing and coloring of knitted fabrics such as pure cotton and polyester cotton, and there is no introduction for printing of other fibers. And There is also no introduction to the color fastness to soaping of fabrics

Abstract

The invention relates to a textile water-based pigment printing binding agent and a preparation method. The textile water-based pigment printing binding agent is prepared in a way that acrylonitrile, ethyl acrylate, butyl acrylate, crylic acid, hydroxyethyl methacrylate, acrylamide, sodium dodecyl sulfate, alcohol dodecyl polyoxyethylene (10) ether, deionized water, ammonium persulfate and sodiumhydrogen sulfite are subjected to emulsion polymerization and then are mixed with pyrolysis closed polyurethane crosslinking agent according to proportion. The product is cured in low temperature condition, has remarkable advantages in the aspects of dry rubbing fastness, wet rubbing fastness, soaping fastness and the like, is simple and easily-controllable in production operation, and is energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to a polyurethane-modified acrylate polymer emulsion and a preparation method thereof, which is an adhesive used in textile pigment printing, especially an adhesive with excellent fastness when baked at low temperature. Background technique [0002] Pigment printing is to form a film of insoluble pigments through adhesives, and mechanically fix them on the surface of fibers, so as to achieve the purpose of color printing. The binder is a polymer film-forming substance, which is the main component of pigment printing. It exists in the printing paste as a dispersion, and is cross-linked to form a film by baking. Since the world's industry is currently aiming at energy saving and environmental protection, the research on adhesives also tends to explore low-temperature and environmental protection. Currently used adhesives generally use N-methylolacrylamide as a cross-linking monomer, but it requires high-temperature baking and also ...
