Abstract
A method of degumming jute fibers with complex enzyme, wherein said complex enzyme comprises pectinase and laccase, comprises the steps of: a. soaking the jute fibers in the water solution of said complex enzyme made from pectinase and laccase and adjusting the weight proportion of said complex enzyme water solution and said jute fibers; b. adjusting the PH value of said complex enzyme water solution, and adjusting the temperature of said complex enzyme water solution to a first temperature, then keeping said complex enzyme water solution with the first temperature for a certain period of time; c. adjusting the PH value of said complex enzyme water solution, and adjusting the temperature of said complex enzyme water solution to a second temperature; then, keeping said complex enzyme water solution with the second temperature for another period of time; d. conducting enzyme deactivation of the jute fibers processed with said complex enzyme.
