| | Reactive Red 66 Usage And Synthesis |
| Preparation | 2-Amino-5-(2-bromoacrylamido)benzenesulfonic acid?diazo, and?4-Hydroxy-6-(methylamino)naphthalene-2-sulfonic acid in acid conditions coupled. | | Properties and Applications | blu-ray red. Red purple 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, dye bath temperature rise to 70 ~ 75 ℃ to heat preservation 15 to 16 minutes, depending on the dyeing depth and decide. Such as dyeing depth greater than 1%, 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. Usean hot mama taught wear take a save smaller MM also can be used for silk, wool fabric printing.
