Description

technical field [0001] The invention belongs to the technical fields of textile printing and dyeing technology and textile inkjet printing ink, and in particular relates to a method for preparing textile paint ink based on cobalt 60 gamma ray irradiation technology. Background technique [0002] Inkjet printing technology is a brand-new printing method. It abandons the complex link of plate making in traditional printing, and directly sprays printing on fabrics, which improves the printing accuracy and realizes small-batch, multi-variety, multi-color printing, and solves the problem of It overcomes the problems of traditional printing, such as large area and serious pollution, so it has broad development prospects. [0003] However, there are still some unreasonable factors in the preparation process of the existing textile inkjet printing coatings. The existing textile inkjet printing coatings enhance the color fastness of the ink by adding a coating binder, and then add th...
