Molecular Structure: anthraquinones
Molecular Weight: 422.43
CAS Registry Number: 6408-72-6
Manufacturing Methods :
Properties and Applications: red light purple. brown-red powder, soluble in alcohol. The strong sulfuric acid in colorless, diluted red for yellow light. In dyeing calcium and magnesium ions not sensitive, encounter iron ion colored light slightly influence, copper ions in big effect. Dye bath appropriate pH value for 3 to 8, in dyeing and printing not alkali resistance. The dyes red light for purple, suitable for polyester/cotton blended fabric dyeing, and have a good color fastness to dry. Suitable for high temperature high pressure and hot melt dyeing method, hot melt temperature of 210 ~ 220 ℃. In three vinegar on fiber dyeing, colored light and polyester similar, is not suitable for dyeing two vinegar fiber, polyamide fiber and acrylic. But in polyester fabric weaving direct printing, cannot be printing the impression of the discharge. And Disperse Violet 26 and the same chemical structure.
