High-performance blended yarn spinning method based on jute fiber

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of jute spinning, in particular to a spinning method of jute fiber-based high-performance blended yarn. Background technique [0002] The price of jute fiber is low, and it has excellent antibacterial, anti-mildew, anti-ultraviolet, easy to degrade and other ecological and environmental protection characteristics. Moreover, my country is rich in jute resources and is one of the third largest jute-growing countries in the world. The output of jute is second only to India and China. Bengal. The development and application of jute fiber has attracted more and more attention. But in jute fiber, the content of lignocellulose and hemicellulose is high, the fiber is thick and hard, the elasticity and elongation at break are low, and the spinnability is poor, which has always restricted the application and development of jute fiber in the field of clothing fabrics. [0003] Tencel is a kind of cellulose fiber. It a...

Problems solved by technology

[0004] However, due to the difference in the properties of jute fiber and tencel fiber, the processing technology is completely different

For example: jute fiber is brittle, short, high-lint, and has a lot of parallel threads. It needs to be equipped with high speed when opening, while tencel fiber can not be blown too much to avoid fibrillation. It needs to be equipped with low speed, so the existing technology cannot be used. Realize the blending of jute fiber and tencel fiber
