Problems solved by technology

Water-based ink has not been widely used in the past, mainly because it has some problems, among which the stability problem has always been an important problem that plagues all dispersion systems
As mentioned above, the high specific heat of water makes it difficult for the ink to cause blockage at high temperature, but it is also because of the high specific heat of water that water-based inks are more difficult to dry than solvent-based inks.

Abstract

The invention relates to water-based heat transfer printing ink and a preparation method thereof, and aims to provide the water-based ink and the preparation method thereof which can effectively solve the problems in stability, drying speed and color brightness to replace solvent printing ink. The technical scheme is that the water-based heat transfer printing ink consists of the following raw materials: deionized water, a disperse dye, a dispersant, a wetting agent, a thickening agent, a cosolvent, an anticorrosive agent, a defoaming agent and a drier. The preparation method for the water-based heat transfer printing ink comprises the following steps of: 1, dissolving the dispersant in water, adding the thickening agent, the wetting agent and the defoaming agent, adding the disperse dye, and stirring and mixing uniformly; 2, grinding and refining the mixed solution obtained from the step 1 to form a pre-disperse solution; and 3, adding the cosolvent, the anticorrosive agent and the drier into the obtained pre-disperse solution, stirring and mixing uniformly, and obtaining a final product by adjusting.

Description

technical field [0001] The invention relates to the field of thermal transfer printing of textiles, in particular to a water-based thermal transfer ink applied to thermal transfer printing and a preparation method thereof. Background technique [0002] Transfer printing is a printing method in which appropriate dyes are printed on special paper to form the desired pattern by printing, and then transferred to the textile by certain means. Now it is mainly divided into two technologies: cold transfer and thermal transfer. Denmark Dansk company jointly proposed a water-based cold transfer printing technology of natural cellulose textile reactive dyes, and jointly developed a complete set of technology and equipment called "Cotton Art" jointly with German Hoechst (Kuster) company and Dutch Stork company. This technique mainly uses reactive dyes for printing on any natural cellulosic textiles, including plain and knitted textiles. For the transfer printing of synthetic fibers, ...
