Fuente: WIPO "hemp" In this invention, autogenetic bacteria of hemp are cultivated under anaerobic condition when their integrated activity is raised to 100-200 mu/ml, artificially cultivated supplementary bacteria are added, thus a complex decomposition enzyme for pectin is formed. The pH and temp. of degumming are controlled, so the growth and reproduction of bacteria is rapid, the activity is maintained at 200-250 mu/ml, and time of degumming is also controlled, so hemp is degummed just in time and in degree. Then it is washed with water to a neutral condition and dried. The degummed hemp produced by the degumming technique of this invention may be woven for 5-36NM hemp. yarn of various grades, the productivity of hemp is raised to 33 percent, the degumming speed is rapid, and the product quality is stable.
