<p>Dye leached from dyed or printed textiles in an aqueous solution can be decolourized by adding enzymes that utilize hydrogen peroxide or molecular oxygen for the oxidation of organic or inorganic substances, including coloured substances, together with a source of H202 or 02. Such enzymes are usually termed peroxidases and oxidases, respectively. This treatment reduces the risk of back-staining (redeposition of dye onto textile) even when less water is used. The enzymatic bleaching of released dyestuff will decrease process time as well as the amount of energy and water needed to achieve a satisfactory quality of the textile, and the colour of the waste water is reduced.</p> |
