Oil Soluble Aniline Black

Oil soluble aniline black is a kind of black dye that is directly generated on cotton fabric and insoluble in common solvents. When dyeing, first immerse the cotton fabric in the solution prepared with aniline salt, and then oxidize it, that is, dye it black. The dye can withstand the sun and rain, and is strong to hot soap solution and dilute bleaching powder solution. When it is oxidized too much, it will be blue black and easy to cause embrittlement. It can turn green when insufficient oxidation or reduced.
