Aqueous inkjet transfer printing method for personalized printing of textiles

Abstract

The invention discloses a water-based ink jet transfer printing method for textile personalized printing. A water-based ink jet transfer printing material sequentially comprises a base material layer,a release layer and an inking layer; the release layer is a PP release layer; the inking layer is formed by mixing 50-85 parts of deionized water, 1-30 parts of nano SiO2 emulsion of which the solidcontent is 20-48%, 0.1-10 parts of sodium alginate and 0.1-3 parts of butynediol ethoxylate and / or butynediol, ink jet printing is conducted on one side of the inking layer to form a mirror image, powdered resin is uniformly spread on the surface of the mirror image, the surfaces of the non-mirror-image positions are cleaned, one side of the image covered with the powdered resin is put on a textile at the temperature of 120-160 DEG C and subjected to high-temperature high-pressure pressing for 8-240 s, cooling is conducted, and a printed textile is obtained by peeling off the transfer printingmaterial; and color printing of textiles of various materials can be achieved, the obtained textile is soft in hand feel, bright in color, resistant to water washing, high in weather resistance and breathable, color restore is better compared with that of direct spraying, the fastness is far higher than that of a direct spraying textile, and the rejection rate is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of water-based inkjet transfer printing, and in particular relates to a water-based inkjet transfer printing method for personalized printing of textiles. Background technique [0002] There are mainly the following methods for textile printing and dyeing complex patterns: gravure printing, screen printing, thermal transfer printing, sublimation printing (textiles containing more than 60% polyester material) and direct injection printing, and the water transfer printing technology of Changsheng Company is host. Among them, gravure printing is suitable for mass printing, and screen printing, heat transfer printing and water transfer printing are all suitable for mass production. The cost of printing a single color pattern is extremely high, and no one in the industry currently uses it as personalized printing; Because sublimation printing uses disperse inks, it is only used for fabrics containing more than 6...

Problems solved by technology

[0003] Direct-injection printing is the first choice for personalized printing in the industry at present, but the process is complicated. Due to the poor surface flatness and inconsistent water absorption of textiles, it is easy to cause problems of dots and poor color reproduction. Clothes need to be pretreated, and due to the water-based coating The solvent is water, which will cause the final product to have poor washing performance, discoloration, and color fastness that cannot meet the requirements; internationally, the coating inks produced by companies such as DuPont will meet the requirements of some customers in terms of color fastness and washing fastness, but The cost of use is extremely high, the process is complicated, and the entire garment is likely to be scrapped due to clogging of the inkjet nozzle or ink splashing during the production process
