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

Low frictional resistance line hook for weaving

[technical field]

The present invention relates to the to weave line hook of use, particularly relates to a kind of frictional resistance that can significantly reduce between yarn and line hook, thereby can effectively guarantee the low frictional resistance line hook for weaving of fabric quality.

[background technology]

On various types of knitting machines, be all provided with line hook, for holding in the palm, hang and guiding yarn, make yarn deliver to knitting needle by the coil of wire warp hook being placed in yarn bracket.Traditional line hook is to be made by stainless steel and other metal materials, this metalloid line hook due to hardness and surface smoothness lower, while making the online hook surface sliding of yarn, between yarn and line hook, there is larger frictional resistance, this frictional resistance makes yarn because unbalance stress produces wearing and tearing, causes the design on fabric surface that is finally made into irregular, out-of-flatness, there is the at random of flaw and line material multiply fiber, and therefore affected surface fine degree and the quality of cloth.For this reason, people have developed ceramic thread hook, although ceramic thread hook makes moderate progress compared with the surface flatness of metal wire hook, but because there is micropore and coarse in surface, therefore its superficial density and fineness are lower, make yarn larger with the frictional force on line hook surface in fabrication processes, cause the running resistance of yarn larger, and cause yarn to affect its retractility because of discontinuity, cause the design on fabric surface that is made into irregular,, there is the at random of flaw and line material multiply fiber in out-of-flatness, has influence on design on fabric surface fineness and quality.In addition,, because ceramic thread hook material is more crisp, make easily to be touched when with line fork wiring disconnected.

[summary of the invention]

The present invention is intended to address the above problem, and a kind of frictional resistance that can effectively reduce between yarn and line hook is provided, and avoids yarn to affect its elasticity and cloth quality because of wearing and tearing, and low frictional resistance line hook for the weaving of long service life.

For achieving the above object, the invention provides low frictional resistance line hook for a kind of weaving, comprise straight-bar and be located at crozier and the Connection Block at straight-bar two ends, it is characterized in that, on the part or all of surface of described crozier, be provided with the fine and close smooth resistance layer of falling of layer of surface.

Described the position contacting with yarn that resistance layer is coated on described crozier falls.

The described resistance layer of falling is the thin slice of being made by zirconia or titanium oxide.

Described zirconia or titanium oxide thin slice fit tightly the outer surface of described crozier, and are adhesively fixed with described crozier.

Described zirconia or titanium oxide thin slice are embedded in the outer surface of described crozier.

The upper surface of described zirconia or titanium oxide thin slice protrudes from the outer surface of described crozier.

Contribution of the present invention is, it efficiently solves the defect that existing line hook has.The fine and close smooth material of the compound layer of surface in position that the present invention contacts with yarn by online hook, thereby surface smoothness and the hardness of line hook have effectively been improved, significantly reduced the frictional resistance of yarn and line hook, the wearing and tearing of yarn have been avoided, keep the original elasticity of yarn, thereby can effectively guarantee surface fine degree and the quality of cloth.The features such as the present invention also has simple in structure, easy to implement and popularization.

[specific embodiment]

The following example is further explanation of the present invention, and the present invention is not constituted any limitation.

Weaving of the present invention is for holding in the palm the metallic rod shaped body with bending of hanging yarn on knitting machine with low frictional resistance line hook 10, it comprises straight-bar 11 and crozier 12 and the Connection Block 13 of one with it, wherein, crozier 12 and Connection Block 13 are integrally formed at the two ends of straight-bar 11, crozier 12 is for holding in the palm extension yarn, Connection Block 13, for being connected with knitting machine support, is described in more detail the present invention below in conjunction with embodiment.

Embodiment 1

Consult Fig. 1, main points of the present invention are, on the crozier 12 of described line hook, be provided with and fall resistance layer 20, this falls the part surface that resistance layer 20 can be arranged on crozier 12, also can be coated all surfaces of crozier 12, this falls resistance layer 20 is made by high rigidity, high density material, and its surface should be fine and close and smooth, this falls resistance layer can reduce the frictional resistance with yarn by fine and close and smooth surface, thereby solve existing metal and ceramic thread hook, affects the problem of fabric quality because of rough surface.

In the present embodiment, described in the position contacting with yarn that resistance layer 20 is coated on described crozier 12 falls, more particularly, this falls resistance layer 20 and is coated on approximately 1/2 circumference in the inner part of described crozier 12, it has covered the position contacting with yarn of crozier 12.The described resistance layer 20 of falling can be that in the present embodiment, this falls resistance layer 20 is thin slices of being made by zirconia or titanium oxide, preferential oxidation zirconium thin slice than metal and ceramic hardness and the higher object of density.The density of zirconia material is 5.68g/cm3, doubles many than ceramic density, and it has high rigidity, high strength, high tenacity, the physical and chemical performance that high ABRASION RESISTANCE and chemical resistance etc. are good.

In the present embodiment, described zirconia thin slice is adhesively fixed with bonding agent and fits tightly in the outer surface of described crozier 12, its upper surface protrudes from the outer surface of described crozier 12, yarn is moved with very low resistance on hook online, frictional force between yarn and line hook is down to minimum, thereby avoided yarn because of the wearing and tearing that unbalance stress produces, keep the original retractility of yarn and elasticity, and guaranteed the quality of fabric.

Embodiment 2

The structure of described line hook 10 is with embodiment 1, and difference is, as Fig. 2, Fig. 3, described zirconia thin slice is by hot pressing, and the conventional methods such as stationary fit are embedded in the outer surface of described crozier 12.
