Manufacturing Methods : 1-Amino-4-bromo-9,10-dioxo-9,10-dihydroanthracene-2-sulfonic acid and 2-Amino-5-(2-bromoacrylamido)benzenesulfonic acid condensation.
Properties and Applications: bright blue. Bright blue powder, 90 ℃ in the solubility of water when for 100 g/L. Suitable for dyeing in weak acid dye bath, pH control in 5 ~ 6, and between the general and the 1 to 2% 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. Used for wool fiber, tops, scattered wool dyeing, also can be used for wool and silk fabric printing.
