Manufacturing Methods :
Properties and Applications: bright blue purple. Violet powder, 90 ℃ water solubility in for 100 g/L. For dyed in acid bath dyeing, pH control in 5 ~ 6 between, general join 1% of leveler PW-BX, can wool Reactive Dye and Lanasol series spell color. Dye bath temperature rise to 70 ~ 75 ℃ to heat preservation 15 ~ 60 minutes, depending on the dyeing depth and decide. Such as dyeing depth greater than 10% need to use liquid ammonia in post-processing, pH value of 8.5, time 15 minutes, temperature of 80 ℃. The dye levelness is bad, but good color fastness, dyeing fabrics after bright color. Can be used for wool fiber, tops and scattered the wool dyeing, can also be used for the wool, silk fabric printing
