Reactive Red 84 Chemical Properties,Uses,Production

Preparation

2-methyl-5-(2′-amino-5′-bromo-phenyl sulfone acrylamido-yl) benzenesulfonic acid diazo, and 6-Aminonaphthalene-2-sulfonic acid coupling.

Flammability and Explosibility

Not classified

Properties and Applications

colourful red yellow light. Orange red powder. 90 ℃ water solubility in for 100 g/L. Suitable for dyeing in weak acid dye bath, pH control in 5 ~ 6 between, general join 1% of leveler PW-BX. This product can and wool Reactive yellow PW-4 G, blue PW-3 G 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. Used for wool fiber, tops, scattered wool dyeing, also can be used for wool, silk fabric printing.
