A process for degumming jute, which includes the following steps: (1) unpacking and bunching of raw jute (2); treating the raw jute with a compound enzyme, which comprises adding to a container an aqueous solution of the compound enzyme made from pectase and laccase so that the jute is treated, taking the jute out the container and patching the jute in a predetermined duration, and finally rinsing the raw jute with hot water (3); reduction bleaching, which comprises adding to the container an aqueous solution of reductive bleaching agent and bleaching the jute, and then adding a decolourizer thereto and treating the jute and finally taking the jute out the container after the treatments are carried out (4) beating the resulting jute, and then rinsing, oiling, dehydrating and drying sequentially, thereby obtaining a decolorized and impurity free jute fiber.
