    摘要: Disperse dye compositions such as powders and pastes containing ammonium lignin sulfonate and an ammonium compound such as ammonium sulfate, acetate or the like, and dyebaths prepared therefrom produce dyeings of high color yield on such fibers as polyester, triacetate, acetate, polyamides, and blends thereof with other natural and synthetic fibers, under adverse conditions such as wide pH variations and the unpredictable effects of various dyebath additives.
