Disperse Orange S-2R
C.I.Disperse Orange 30
Molecular Structure: Single azo class
Molecular Weight: 450.27
CAS Registry Number: 12223-23-3/5261-314
Manufacturing Methods : 2,6-Dichioro-4-nitroaniline diazo, and 2-((2-Cyanoethyl)(phenyl)amino)ethyl acetate;N-(2-cyanoethyl)-N-(2-acetoxyethyl)benzeneamine coupling.
Properties and Applications: Orange. Brown powder. In dyeing copper and iron ion to the colored light have-will influence, dyeing appropriate pH value for 4 to 7. The dye sublimation and sun good fastness, suitable for color dyes as tricolor spell. In dyeing method of high temperature and high pressure, can spell in the dark, into. Dyeing, the size of the bath ratio of coloring rate is influential, dyeing vinegar fiber, color is yellow than polyester, polyamide fiber dyed the soaping fastness is poorer, dye acrylic dyeing rate when is low. Can make polyester and cotton/polyester direct printing and prevent the discharge printing to color.
