Insoluble in water, slightly soluble in acetone, acetic acid, carbon tetrachloride, soluble in acetone, ethanol, glycol single ethyl ether, in ethanol for blue. The strong sulfuric acid in yellow or brown, after dilution of dark precipitation. In dyeing copper and iron ion color change. Used for polyester and their blended fabric dyeing and printing, for green light blue emerald green. The low power points, dye deep sex differences. High temperature and high pressure method is suitable for dyeing polyester. The dyes in high temperature alkaline conditions can decompose, dye bath appropriate pH value for 5 ~ 6, with carrier will affect dyeing of sun fastness, dyeing hot to dissolve solid color rate is low. For dyed fiber green light blue for two vinegar, colour and lustre is colourful bright, the dyeing speed, have very good devoured rate, levelness and dye deep sex all good, but the dye deep wet process fastness is poorer. Three vinegar fiber dyed blue green light when the dyeing speed and dye deep sex medium. This product can also be used for direct printing polyester fabric.
