Abstract

The invention discloses an ink-jet printing coating adhesive for fabrics and a preparation method. The preparation method comprises the following steps: using methyl methacrylate, n-butyl methacrylate, glycidyl methacrylate, allyl methacrylate, chlorinated methacrylic acid trimethyl ammonia ethyl ester, fatty alcohol-polyoxyethylene ether XL90, cetyltrimetheylammonium bromide, 2,2-azobis (2-methyl propionamidine) hydrochloride, deionized water, nanometer SiO2 and associative polyurethane leveling rheological agent WT-203 as raw materials; and forming the coating adhesive through four-step processes of emulsification, induced polymerization, nanometer SiO2 dispersion and thickening complex. The invention has simple and convenient production method, and is applied to the coatings on various natural fibers and synthetic fiber fabrics with good firmness, the printing color is not dissolved in water, and the line profile is clear without diffusion.

Description

technical field [0001] The invention relates to a coating adhesive for treating textile cloth when the textile is printed with water-based dye ink, that is, the textile coated with this adhesive can adopt a digital ink-jet printing process. It is required that the coating glue contains cationic active groups that can undergo cross-linking reactions with dye molecules, so that the printed product has the performance of not decolorizing when exposed to water; it contains epoxy active groups with good bonding fastness to the base fabric to meet the washing fastness standard ; Contains powder medium with strong adsorption capacity and large specific surface area to achieve clear printing outline and no seepage. Background technique [0002] In recent years, the application of digital printing technology has become more and more extensive, and textile printing is also facing opportunities and challenges. Textile digital inkjet printing is an innovative dyeing and finishing proces...
