The wettable indigo is produced by stoving the acid washing indigo together with additive. It is used in printing and dyeing industry, and has characteristics of little flying dust, good water solubility and quick reduction speed. It has good affinity to cotton fiber, and high utilization ratio of dyes. The color is homogenic after dyeing, and the color light is brilliant. The fastness to both dry grinding and wet grinding is better than the initial indigo powder.
