Abstract:This invention concerns an ecologically friendly process of indigo (C.I. Vat Blue 1 ) dyeing of cellulose and polyamide-containing textile material with possibility of reusing (three or more times) the enzyme reduction dyeing bath. Procedure of dyeing cellulose and polyamide textile materials with enzymatically reduced indigo comprising the step of subjecting the cellulose or polyamide samples to the indigo dyebath containing reductases (e.g. NADH-dependent enzymes from Bacillis subtilis in the presence of a redox mediator (e.g.1,8- dihydroxy-9,10-anthraquinone), oxidation on air or oxidases enzyme or oxidizing agent (i.e. hydrogen peroxide) after diffusion leuko indigo into material and finally soaping and washing.
