METHOD OF ENZYMATIC COTTON-CONTAINING FABRIC DESIGNING Russian patent published in 1996 - IPC

FIELD: textile industry. SUBSTANCE: method involves enzymatic treatment of cotton-containing fabrics by impregnation with an aqueous solution containing enzyme peroxidase (from basidial fungus Cerrena maxima Murr), sodium chloride, thermic treatment, washing. Impregnation is carried out at 20-25 C with solution that contains additionally glucoamylase (from yeast-like microorganism Endomycopsis species), lipase (from microorganism Mucor pusillus) and thiourea at the following ratio of components, g/l: peroxidase 0.1-1; glucoamylase 0.1-1; lipase 0.1-1; sodium chloride 0.1-0.5; thiourea 0.1-0.5, and water up to 1 l. Thermic treatment is carried out at 35-50 C for 10-30 min. EFFECT: improved method of fabric DESIGNING. 1 tbl
