Abstract

The invention discloses thermal-sublimation water-based intaglio printing ink and a preparation method thereof. The thermal-sublimation water-based intaglio printing ink is composed of components in percentage by weight: 15-35% of disperse dye size, 24-50% of an N-vinylamide-acrylic ester copolymer emulsion, 0.3-2.5% of a thickening agent, 0.1-2% of an antifoaming agent, 0.1-3% of a neutralizer, 0.1-0.5% of a preservative and 10-42% of de-ionized water. The thermal-sublimation water-based intaglio printing ink has high heat resistance; and transferred printing paper is not adhered to a cloth material in a transfer printing process. The thermal-sublimation water-based intaglio printing ink also has excellent storage stability; patterns printed on various transferred printing paper are clear; the printing patterns transferred onto dacron, nylon cloth material and textile have clear profiles without any friction ghosting and transfer ghosting and are bright in color; and color fastness complies with wearing requirements. The thermal-sublimation water-based intaglio printing ink has no any toxic organic solvent residue, can be diluted with water and is good for safe production and environment protection.

Description

technical field [0001] The invention belongs to the field of inks, and in particular relates to a sublimation water-based gravure printing ink and a preparation method thereof. Background technique [0002] The sublimation transfer printing technology of disperse dyes has been applied to synthetic fiber fabrics since the 1970s, and it is still stable at more than 5% of the total global printing industry. The use of sublimation water-based gravure printing ink is to print the ink on the transfer paper first, and the printed paper and the fabric are overlapped in a heat press machine and heated (150-250°C) under pressure. The dye in the ink layer is heated and directly From solid dye to gaseous phase, it penetrates into the fiber and makes it colored. The printing process of this kind of textile cloth and fabric does not need to be washed, and the cloth feels soft after printing, which not only saves costs but also does not pollute the environment. In addition, the entire pr...
