The method for producing jute fiber comprises the steps of: scouring the jute material to improve the absorption and fibrillation; bleach the washed jute to improve the fibrillation and fibrillation of the jelly fiber whiteness, followed by reduction treatment ,neutralize. The hemp is then treated with a surface softener for bleaching, scouring, fibrillation for 30-60 minutes, dehydrating and drying the fibrillated hemp; opening the fiber from the fibrillated jute to separate the jute fibers The Then, the aqueous emulsion of the surface and the internal softener is sprayed onto the jute fibers; and the sprayed jute fibers are cooked in the steam chamber, thereby producing a soft, flexible and spinnable fine jute fiber.
