| Properties and Applications | red light navy blue, navy blue. Blue gray powder, soluble in acetone. In dyeing of iron ion basically no influence on color, copper ions in great influence, the alkali sensitive, dye bath pH for 5 ~ 6. The dye is suitable for high temperature and high pressure dyeing, dyeing deep color, sublimation fastness is better, the high temperature can finalize the design, when the piece dyed levelness slightly less. In three vinegar fiber dyeing, slant red light, not suitable for two vinegar fiber dyeing. Acrylic and polyester fiber, with the dye printing, color is not enough gaudy. And with plasma reactive dye printing, colored light can change.
