Vat dyes are water insoluble after oxidation and therefore they can be largely eliminated by adsorption on the activated sludge in waste water treatment plants. Vat dyes contain heavy metal impurities (Cu, Fe, Pb, Ba, Mn) used during production. In some cases it is still difficult to keep these limits below the ETAD standards. Pigments
For example, with suitable auxiliaries grey yarn can be scoured and dyed simultaneously by the high temperature process above 100 o C. Typical Recipe for Vat Dyeing: A typical recipe for a dye liquor would be: Caustic soda (27% by weight), 5 ml l1; Hydrosulphite, g l1; Stock vat, ml l1.
