Problems solved by technology

Conventional acrylate emulsion type pigment printing adhesives have problems such as hard hand feeling, unsatisfactory color fastness, sticking to rollers during padding, etc.
Moreover, most acrylate pigment printing adhesives on the market contain a certain amount of N-methylolacrylamide (NMA) crosslinking monomer, and the printed fabric will release formaldehyde during baking and storage, and the export of products is restricted.

Abstract

The invention discloses a preparation method and use of a ketone hydrazine crosslinkable acrylic ester and polyurethane composite textile emulsion. Cobalt 60 - gamma radiation method polymerization process is used for overcoming low color fastness and high aldehyde content of the bond of resinfixed pigment printing. Acrylic ester emulsion incorporating active ketone carbonyl is synthesized by acrylic ester mixxed with monomer and diacetone acrylamide(DAAM). The ketone hydrazine crosslinkable acrylic ester and polyurethane (PUA) composite textile emulsion is prepared by mixxing the acrylic ester emulsion with polyurethane emulsion incorporating diazanyl in definite proportions. Infra-red spectrum(IR), mechanical property and hydrolytic resistance deo tecting methods are used to analyze the composite textile emulsion and to detect the color fastness and environmental protection of the bond of resinfixed pigment printing. The result indicates when the content of DMMA is between 1.3 and 1.4 percent, the performance of the PUA composite textile emulsion is good and the bond based on the emulsion is an environmentally friendly product which is aldehydeless and without APEO, the aldehyde content satisfy infant clothing, and colour fastnes to brush-washing and crocking fastness are improved.

Description

technical field [0001] The invention belongs to a production method of textile printing paint, in particular to a preparation method of ketone hydrazine cross-linked acrylate-polyurethane composite textile emulsion. Background technique [0002] Pigment printing process is simple, clean and economical. About half of the printed fabrics produced in the world are printed by pigment printing process. Conventional acrylate emulsion type pigment printing adhesives have problems such as hard hand feeling, unsatisfactory color fastness, and sticking to rollers during pad dyeing. Moreover, most acrylate-based pigment printing adhesives on the market contain a certain amount of N-methylolacrylamide (NMA) crosslinking monomer, and the printed fabric will release formaldehyde during baking and storage, and the export of products is restricted. Therefore, the modification of conventional acrylate emulsions has become one of the hot spots in the textile industry. Contents of the inven...
