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.

Abstract: The present invention introduces a process of spinning bast fibers through health preserving. Various examples include health preserving bast fibers; opening and cleaning, and carding the health preserved bast fibers, and drawing the carded health preserved bast fibers into bast fiber strips; health preserving said bast fiber strips; and spinning the health preserved fiber strips into yarn. Examples of the present invention also introduce a kind of yarn made by such processes. Examples of the present invention further introduce a process of blended spinning bast fiber with other fibers through health preserving, and the yarn made by such processes. Examples of the present invention realize low end breakage rates, and high efficiency, so as to achieve high quality products.
