| 20100192308 | METHOD FOR SCOURING AND BLEACHING COTTON FABRIC WITH COMPOSITE ENZYME PREPARATION IN ONE BATH - A method for scouring and bleaching cotton fabric with composite enzyme preparation in one bath is provided. The method relates to the application of composite alkaline enzyme preparation in scouring and bleaching processes of cotton fabric. The enzyme preparation for scouring and bleaching cotton fabric is compounded from cutinase, alkaline pectase, alkaline xylanase, alkaline cellulose, and carbohydrate oxidase. The method includes: scouring the cotton fabric by adding the composite enzyme preparation, glucose, oxidation bleaching stabilizer RB-3, penetrant JFC, and Triton X-100 in a treating bath at 55-70° C. and pH 8-10, and then bleaching the cotton fabric for 30 min by directly adding tetraacetyl ethylenediamine (TAED) in the scouring bath to activate hydrogen peroxide. After being treated by the method of the present invention, the cotton fabric has high impurity removal ratio, favorable wettability, and high whiteness. The present invention has the advantages of low power consumption, short process flow, and being environment friendly, and may be used to replace conventional chemical treatment process under the condition of concentrated alkali and high temperature. | 08-05-2010 |
