Our product range includes a wide range of naphthol astr dye, naphthol asg dye, naphthol asbs dye, naphthol asbo dye, naphthol asd dye and napthol as powder dye.
They are organic powder dyes, used in two–step dyeing: first the fibre is treated with Naphthol (alkaline), then coupled with a diazo salt to form the final insoluble azo dye within the fabric.
