Protonated leuco indigo (indigo white) in aqueous ethanolic solutions could be utilized for indigo dyeing under neutral conditions. Dyeing behaviors of indigo white onto nylon and cellophane films were investigated. The results obtained were as follows : (1) The amount of the absorbed dye decreased with an increase in the concentration of ethanol. (2) The adsorption of indigo white was not influenced by an addition of salts. The extent of damage of wool and silk fabrics dyed in the neutral bath was smaller than that obtained from alkaline bath.
