Abstract

The invention discloses dihydric alcohol type active dye ink. The active dye ink comprises the raw materials of active pigments, ethylene glycol, 1,3-propanediol, 1,2-hexanediol ethanol, diethylene glycol, a buffer agent, a surfactant, and deionized water. The active pigments in the active dye ink are prepared by mixing glycol and 1,3-propylene glycol in a proportion of 1 to 1, so that the durability of the dye ink can be improved, and the dye ink has good moisture preserving property, K/S value and color fixation rate; meanwhile, by adding 1,3-hexanediol, on one hand, the stability of the inkcan be improved by virtue of 1,3-hexanediol as an ink solvent, the surface tension of the dye ink can be adjusted by virtue of 1,3-hexanediol as a surface tension regulator, the viscosity of the inkcan be adjusted, and the decrease of the color fixation rate of the ink in the storage process can be improved; and by adding diethylene glycol, a hydrogen bond generated by diethylene glycol and water is relatively strong and is unlikely to be broken, so that the layering of the active dye link can be avoided.

Description

technical field [0001] The invention relates to the field of textile printing, in particular to a dihydric alcohol reactive dye ink. Background technique [0002] Ink quality directly determines the quality of printed textile products. The ink is mainly divided into two types: paint type and dye type. Since the paint is insoluble in water, it is easy to block the nozzle. It needs to be ground and added with an effective dispersant to make it well dispersed, so the production process is complicated. , the price is high. Compared with it, the main advantages of dye-based inks are: bright colors, low cost, good ink stability, and not easy to clog the nozzles. Dye-based digital inkjet printing inks can be divided into reactive dyes, acid dyes, direct dyes and disperse dyes according to the types of dyes. Due to the current popularity of cotton fabrics, reactive dye inks have high research value. In addition to reactive dyes and double distilled water, its main components also...
