Problems solved by technology

However, as a natural fiber, hemp fiber has a large difference in length and fineness distribution, and has a large single fiber stiffness, which also has more requirements for the production process of spinning and weaving. Therefore, it is mostly realized by blending with cotton and viscose fiber, but this It also brings about the phenomenon of different yarn shades or color flowers due to the difference in the color yield of the two fibers
In addition, the fiber of hemp needs to go through processes such as seed removal, retting, and beating. The growth cycle is long and affected by the environment, coupled with the limitations of processing conditions and equipment, making pure flax and ramie high-count yarn fabrics expensive. In addition, due to the special requirements of hemp on the growth environment, its production is restricted by great geographical factors.

Embodiment 1

[0036] The ratio of red, brown and white filaments that make up the multifilament is 6:1:13. The target yarn is a light red yarn with a hemp-like distressed feel, which is applied to light and light hemp-like fabrics for clothing.

[0037] In the rear drafting area: the diameter of the two rollers is 25mm, and the horizontal center distance is 50mm. The pressure of the rear roller is 14daN / double spindle, and the pressure of the middle roller is 12daN / double spindle. The added pressure roller has a diameter of 6mm, and the vertical distance between the center of the bottom roller 11 in the bottom pressure roller 4 is 30mm. The number of corundum leather meshes from small to large is as follows: the upper and lower pressure rollers have a corundum leather mesh of 50 mesh, and the corundum leather meshes of the two aprons of the middle roller are both 80 mesh, and the corresponding particle sizes are: 297 and 178 grains respectively; The wrapping angle 5 formed by the roller a...

Embodiment 2

[0042]The proportion of blue, brown and white filaments that make up the multifilament is 12:1:7. The target yarn is blue yarn with hemp-like distressed feeling, which is applied to thicker hemp-like canvas fabrics.

[0043] In the rear drafting area: the diameter of the two rollers is 25mm, and the horizontal center distance is 50mm. The pressure of the rear roller is 16daN / double spindle, and the pressure of the middle roller is 14daN / double spindle. The added pressure roller has a diameter of 6mm, and the vertical distance between the center of the bottom roller 11 in the bottom pressure roller 4 is 30mm. The number of corundum leather meshes from small to large is as follows: the upper and lower pressure rollers have a corundum leather mesh of 45 mesh, and the corundum leather meshes of the two aprons of the middle roller are both 60 mesh, and the corresponding particle sizes are: 350 and 250 grains; The wrapping angle 5 formed by the roller and the yarn is 60°; the wrap...

Embodiment 3

[0048] The ratio of brown and white filaments that make up the multifilament is 3:2. The target yarn is an old-fashioned yarn with the natural color of linen, which is applied to linen-like fabrics for craft decoration.

[0049] In the rear drafting area: the diameter of the two rollers is 25mm, and the horizontal center distance is 50mm. The pressure of the rear roller is 18daN / double spindle, and the pressure of the middle roller is 16daN / double spindle. The added pressure roller has a diameter of 6mm, and the vertical distance between the center of the bottom roller 11 in the bottom pressure roller 4 is 30mm. The number of corundum leather meshes from small to large is as follows: the upper and lower pressure rollers have a corundum leather mesh of 35 mesh, and the sand leather mesh of the two aprons of the middle roller are both 50 mesh, and the corresponding particle sizes are: 500 and 297 grains; The wrapping angle 5 formed by the roller and the yarn is 80°; the wrappi...

Abstract

The invention relates to a spinning device for imitation linen yarn and its filament yarn processing method. Rollers, middle rollers are respectively provided with aprons, and pressure rollers are arranged between the middle rollers and the back rollers, wherein the pressure rollers and the aprons of the middle rollers are respectively wrapped with carborundum skins, and the pressure rollers and the yarn formed The wrapping angle is 45-90 degrees, the wrapping angle formed by the upper pressure roller and the yarn is 0-45 degrees, and several metal springs are respectively embedded on the electrothermal melting and pressing rollers. The method is as follows: feed colored polyester filaments to the entrance of the spinning device, and the filament bundles pass through the rear roller, pressure roller, middle roller, electric heating roller and front roller in sequence. The invention improves the ring spinning technology, spins the polyester filament yarn with hemp yarn feel, reduces the production cost, has the hemp feel and has the durability and mechanical strength of chemical fiber, and shortens the production process and cycle.

Description

technical field [0001] The invention belongs to the technical field of processing hemp-like yarn, in particular to a spinning device for hemp-like yarn and a filament yarn processing method thereof. Background technique [0002] The short stripes of different lengths and thicknesses formed on the surface of linen-containing fabrics due to uneven dryness have become the unique rough style of linen fabrics, and also make the fabrics cool, breathable, stiff but not hard to wear. However, as a natural fiber, hemp fiber has a large difference in length and fineness distribution, and has a large single fiber stiffness, which also has more requirements for the production process of spinning and weaving. Therefore, it is mostly realized by blending with cotton and viscose fiber, but this It also brings about the different shades of the yarn or the phenomenon of color flowers due to the difference in the color yield of the two fibers. In addition, the fiber of hemp needs to go throu...
