Problems solved by technology

[0004] The first purpose of the present invention is to improve the traditional ring spinning frame, to provide a spinning device in which short fiber bundles are coated with rigid fiber filaments, to overcome the fact that the current rigid fibers are very brittle and not resistant to bending and extrusion. In the process of rewinding and weaving, the problem of fiber bending and brittle fracture is very easy to occur. Various short fiber bundles are used to spin rigid fiber filaments to make it resistant to bending, shearing, torsion and high wear resistance. Soft, comfortable and more functional composite yarn

Abstract

The invention provides a spinning method and device for symmetrically covering a rigid fiber filament by short fiber bundles. The spinning device comprises a ring spinning frame and is characterized by comprising a filament cylinder and a yarn guider, wherein one roller of a front roller pair of the ring spinning machine is a slotting roller, and a backing-off roll is arranged between the slotting roller and the yarn guider. By adopting the spinning device, under the drive of the front roller pair, a rigid fiber filament on the filament cylinder is fed into the backing-off roll through the yarn guider, enters a slot of the slotting roller and is output along the slot, the rigid fiber filament is fed into the front roller pair through a rear roller pair and a middle roller pair, and two strands of symmetrical short fiber bundles output by the front roller pair are converged at a convergence point; meanwhile, the short fiber bundles formed by rotary twisting are covered on the outer surface of the rigid fiber filament to form a composite yarn. According to the invention, the rigid fiber filament is produced into the softer and more comfortable composite yarn with the advantages of bending, shearing and torsion resistance and high wear resistance and multiple functions.

Description

technical field [0001] The invention relates to a spinning method and a spinning device for symmetrically covering rigid fiber filaments with short fiber bundles. Background technique [0002] Carbon fibers have long been known as fibers suitable as structural materials and reinforcing composite materials. Because carbon fiber has high strength, high modulus, and excellent properties such as light resistance, heat resistance, and corrosion resistance, it is compounded with other materials to strengthen and last. However, carbon fiber is very brittle, and it is very prone to bending and brittle fracture of the fiber during rewinding and weaving processing. Therefore, the commonly used carbon fiber composite materials are firstly preformed and then coated with resin to solidify the structure and composite materials into the desired shape. Due to the bending, friction and other damages in the weaving process, in order to protect the carbon filaments, dipping Glue, oiling and ...
