Properties and Applications:  yellow orange. Orange powder. Soluble in water, 90 ℃ water solubility in for 80 g/L. For dyed in acid bath dyeing, pH control in 5 ~ 6 between, general join 1% of leveler PW-BX, 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. This product in strong sulfuric acid or hydrochloric acid for red light in orange, encounter sodium hydroxide for gold orange. Used for wool fiber, tops, scattered wool dyeing, also used for wool and silk printing.
