Properties and Applications:

Brilliant yellow orange yellow powder is soluble in ethanol, benzene and acetone dyeing process met iron, calcium and magnesium ions colored light did not change; A slight change in copper ions. The dye appropriate PH value for 3 to 8, dyeing and printing can do when a: the dye for green light yellow, can the fastness, good resistance to sublimate fastness: suitable for high temperature and high pressure, the melt method and dyeing, levelness passable, carrier dyeing method is a bit poor: in two vinegar on fiber dyeing performance generally., in three of the dyeing performance on fiber vinegar is a bit poor: dyeing nylon 6 and nylon 66 performance is poor, dyed black eye performance generally; Can make polyester/cotton directly Yang flowers, printing and dyeing can use DE colin ferrie sulfate-potassium thiosulfate or. Used for polyester and their blended fabric dyeing, can also be used to vinegar fiber, polyamide fiber dyeing and printing: chemical structure and C.I.Disperse Yellow 32 and the same.
