REACTIVEBLUE50 Chemical Properties,Uses,Production
Preparation
1-Amino-4-bromo-9,10-dioxo-9,10-dihydroanthracene-2-sulfonic acid and 3-Amino-5-(2,3-dibromopropanamido)-2,4,6-trimethylbenzenesulfonic acid?condensation.
Properties and Applications
red light blue. Violet powder, soluble in water, 90 ℃ water solubility in 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 for 8. 5, 15 minutes time, 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 used for wool, silk and polyester/cotton blended fabric printing.
