Manufacturing Methods : the between 1-(3-Aminophenyl)urea and 2,4,6-Trichloro-1,3,5-triazine first condensation, 7-Aminonaphthalene-1,3,6-trisulfonic acid diazo, and condensation products coupled,
again with a between, 2-(3-Aminophenylsulfonyl)ethyl hydrogen sulfate condensation, and then salting-out.
Properties and Applications: red light
yellow. Orange powder. Soluble in water, in the water
solubility of 80 g/L. After dyeing fabric as the red light yellow, in dye bath
of metal ions in iron, a little yellow color a little dark; Copper ions in that
red light shadow change. The dye move color performance for grade 5, neutral
white a category 5, white alkaline for 3 ~ 4 levels. Mainly used for cellulose
fiber dyeing, suitable for polyester/cotton, polyester/stick blended fabric
dyeing of a bath.
