The invention discloses a high-performance blended yarn spinning method based on jute fiber. The method comprises the steps that raw materials are selected, wherein the raw materials comprise 50-62 parts of jute fiber, 8-10 parts of cotton fiber, 6-12 parts of spun silk fiber, 5-10 parts of synthetic fiber and 6-9 parts of viscose fiber; artificial mixing is conducted, wherein the cotton fiber ismanually mixed with the viscose fiber and the synthetic fiber separately; the jute fiber and the spun silk fiber are mixed, the mixture is mixed with the mixture obtained after mixing in step 2, the mixture is processed through a carding machine, wherein in the carding machine, the cylinder speed is set to range from 300 r / min to 360 r / min, the licker-in speed is set to range from 810 r / min to 850r / min, the cover plate speed is controlled to range from 90 mm / min to 100 mm / min, the doffer speed is controlled to range from 20 r / min to 30 r / min, five distances of a cylinder and a cover plate from an inlet to an outlet are 0.2 mm, 0.2 mm, 0.21 mm, 0.22 mm and 0.21 mm respectively; composite fringes of synthetic fiber are obtained, and drawing and roving are conducted. Accordingly, jute spinning products uniform in blending, good in air permeability and low in cost are provided.
