A significant factor preventing the achievement of zero chromium in the effluent from the after‐chrome dyeing process is the presence of soluble proteins in the dyebath. These proteins can react with the dichromate anion and thus interfere with its reaction with the wool fibre and dye molecules. This understanding may lead to the development of very low chromium in effluent dyeing methods that ensure the viability of chrome dyeing.
