Low-friction resistance thread hook for spinning

Abstract

A low-friction resistance thread hook for spinning comprises a straight rod (11), a hook-shaped body (12) and a connecting base (13), wherein the hook-shaped body (12) and the connecting base (13) are arranged at the two ends of the straight rod. The low-friction resistance thread hook is characterized in that partial or all surface of the hook-shaped body (12) is provided with a resistance reduction layer (20) with the surface being dense and smooth, and the resistance reduction layer (20) wraps the part, making contact with yarn, of the hook-shaped body (12). The resistance reduction layer (20) is a thin sheet made of zirconium oxide or titanium oxide. The smoothness and hardness of the surface of the thread hook can be effectively improved, the frictional resistance between the yarn and the thread hook is greatly reduced, the yarn is prevented from being abraded, the original elasticity of the yarn is kept, and the fineness and quality of the surface of cloth can be effectively guaranteed. The low-friction resistance thread hook has the advantages of being simple in structure, easy to implement and popularize and the like.

Description

【Technical field】 [0001] The invention relates to a thread hook for weaving, in particular to a thread hook with low frictional resistance for weaving which can greatly reduce the frictional resistance between the yarn and the thread hook, thereby effectively ensuring the quality of fabrics. 【Background technique】 [0002] Wire hooks are all provided on various types of knitting machines for supporting and guiding yarns, so that yarns are sent to knitting needles by coil warp hooks placed on yarn supports. Traditional wire hooks are made of stainless steel and other metal materials. Due to the low hardness and surface finish of this type of metal wire hooks, when the yarn slides on the surface of the wire hook, there is a large frictional resistance between the yarn and the wire hook. This kind of frictional resistance causes the yarn to wear due to uneven force, resulting in irregular, uneven surface of the final woven fabric, defects and scattered fibers of the thread mate...

AI Technical Summary

Problems solved by technology

Traditional wire hooks are made of stainless steel and other metal materials. Due to the low hardness and surface finish of this type of metal wire hooks, when the yarn slides on the surface of the wire hook, there is a large frictional resistance between the yarn and the wire hook. This kind of frictional resistance causes the yarn to wear due to uneven force, resulting in irregular, uneven surface of the final woven fabric, defects and scattered fibers of the thread material, and thus affects the surface fineness and quality of the fabric. quality

For this reason, people have developed ceramic wire hooks, although the surface smoothness of ceramic wire hooks is improved compared with metal wire hooks, but due to the presence of micropores and roughness on the surface, its surface density and smoothness are low, making the yarn During the process, the friction force with the surface of the wire hook is relatively large, resulting in a large running resistance of the yarn, and causing the yarn to affect its stretchability due to uneven force, resulting in irregular, uneven and flawed fabric surface. And the scattered fibers of the thread material affect the fineness and quality of the surface of the cloth

In addition, due to the brittle material of the ceramic thread hook, it is easy to be broken when the thread is loaded with a thread fork
