The active ink has complete color spectrum and bright color, can also endow fabrics with firm water resistance, and can keep the bright and bright color of the fabrics after washing, so that the active ink is often applied to printing of patterns of high-luxury brands of clothes.
The monochlorotriazine reactive dye black ink and the vinyl sulfone reactive dye black ink are the reactive dye black ink commonly used in the market. In recent years, the use amount of viscose, blending, modal and other man-made cotton cloth in the market is increased sharply, but the black ink of the monochlorotriazine reactive dye has lighter coloring and poorer fastness on the man-made cotton cloth. The vinyl sulfone dye black ink has deeper coloring and good fastness to human cotton cloth, but the dye is easy to hydrolyze and has lower pH value, and has larger damage risk to a printing nozzle. Therefore, developing an active ink which can be applied to the cotton cloth of people and has the characteristics of deep color, good fastness, long-acting stability, no damage to a spray nozzle and the like becomes a problem to be solved urgently.
