Patent ID: 8357487

Claim:
A method of degumming jute fibres with complex enzyme, wherein said complex enzyme comprises pectinase and laccase, comprising the steps of: a) soaking the jute fibres in a water solution of said complex enzyme made from pectinase and laccase, wherein the weight proportion of said complex enzyme water solution and jute fibres ranges from 12:1 to 40:1; b) adjusting pH value of said complex enzyme water solution to more than 5.5, but no more than 6.5, and adjusting the temperature of said complex enzyme water solution to 35°-65°, then keeping said complex enzyme water solution with said temperature value for 20-120 minutes; c) adjusting the pH value of said complex enzyme water solution to 7.5-9.5, and adjusting the temperature of said complex enzyme water solution to 40° C.-70° C.; then, keeping said complex enzyme water solution with said temperature value for 20-120 minutes to obtain processed jute fibres d) deactivating the enzyme complex of step c.
