Abstract
A kind of low frictional resistance line hook for weaving, crozier (12) and Connection Block (13) that it comprises straight-bar (11) and is located at straight-bar two ends, it is characterized in that, be provided with the fine and close smooth resistance layer (20) of falling of layer of surface on the part or all of surface of described crozier (12), this falls resistance layer (20) and is coated on the position contacting with yarn of described crozier (12). Falling resistance layer (20) is the thin slice of being made up of zirconia or titanium oxide. The present invention can effectively improve surface smoothness and the hardness of line hook, has significantly reduced the frictional resistance of yarn and line hook, has avoided the wearing and tearing of yarn, has kept the original elasticity of yarn, thereby can effectively ensure 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.
Description
[technical field]
The present invention relates to the to weave line hook of use, particularly relates to one and can significantly reduce yarn and line hookBetween frictional resistance, thereby can effectively ensure 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 hold in the palm hang and guiding yarn, make yarn byThe coil of wire warp hook being placed in yarn bracket is delivered to knitting needle. Traditional line hook is by metals such as stainless steelsMaterial is made, this metalloid line hook due to hardness and surface smoothness lower, make the online hook table of yarnWhen face slides, have larger frictional resistance between yarn and line hook, this frictional resistance makes yarnBecause unbalance stress produces wearing and tearing, cause the design on fabric surface that is finally made into irregular, out-of-flatness, occursFlaw and line material multiply fiber at random, and therefore affected surface fine degree and the quality of cloth.For this reason, people have developed ceramic thread hook, although ceramic thread hook has compared with the surface flatness of metal wire hookInstitute improves, but because surface exists micropore and coarse, therefore its superficial density and fineness are lower, makeYarn is larger with the frictional force on line hook surface in fabrication processes, causes the running resistance of yarn larger,And cause yarn because discontinuity affects its retractility, 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 can effectively reduce between yarn and line hook and provide a kind ofFrictional resistance, avoids yarn to affect its elasticity and cloth quality because of wearing and tearing, and the spinning of long service lifeKnit with low frictional resistance line hook.
For achieving the above object, the invention provides a kind of weaving with low frictional resistance line hook, comprise straight-barCrozier and Connection Block with being located at straight-bar two ends, is characterized in that, in the part of described crozier orAll surfaces is provided with the fine and close smooth resistance layer of falling of layer of surface.
The described position contacting with yarn that falls resistance layer and be coated on described crozier.
The described resistance layer of falling is the thin slice of being made up of zirconia or titanium oxide.
Described zirconia or titanium oxide thin slice fit tightly the outer surface of described crozier, and with described hookShape body is adhesively fixed.
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 present invention is logicalCross the fine and close smooth material of the compound layer of surface in position that online hook contacts with yarn, thereby effectively changeBe apt to surface smoothness and the hardness of line hook, significantly reduced the frictional resistance of yarn and line hook, kept awayExempt from the wearing and tearing of yarn, kept the original elasticity of yarn, thereby can effectively ensure the surface essence of clothFineness and quality. The features such as the present invention also has simple in structure, easy to implement and popularization.

[detailed description of the invention]
The following example is further explanation of the present invention, and the present invention is not formed to any limitSystem.
Weaving of the present invention with low frictional resistance line hook 10 be on knitting machine for hold in the palm hang yarn with foldingCurved metallic rod shaped body, it comprises straight-bar 11 and crozier 12 and the Connection Block 13 of one with it, itsIn, crozier 12 and Connection Block 13 are integrally formed at the two ends of straight-bar 11, and crozier 12 is for holderHang yarn, Connection Block 13, for being connected with knitting machine support, is done the present invention below in conjunction with embodimentBe described in more detail.
Embodiment 1
Consult Fig. 1, main points of the present invention are, on the crozier 12 of described line hook, are provided with and fall resistance layer20, the part surface that this falls resistance layer 20 and can be arranged on crozier 12, also can be coated the complete of crozier 12Portion surface, this falls resistance layer 20 is made up of high rigidity, high density material, and its surface should be fine and close and smooth,This falls resistance layer can pass through fine and close and smooth surface minimizing and the frictional resistance of yarn, thereby solves existingMetal and ceramic thread hook affect the problem of fabric quality because of rough surface.
In the present embodiment, described in the portion contacting with yarn of described crozier 12 resistance layer 20 is fallen is coated onPosition, more particularly, this fall resistance layer 20 be coated on described crozier 12 in the inner part approximately 1/2 circleZhou Shang, it has covered the position contacting with yarn of crozier 12. The described resistance layer 20 of falling can be ratioThe object that metal and ceramic hardness and density are higher, in the present embodiment, this falls resistance layer 20 is by zirconiaOr the thin slice made of titanium oxide, preferential oxidation zirconium thin slice. The density of zirconia material is 5.68g/cm3,Double than ceramic density many, it has high rigidity, high strength, high tenacity, high wearability andThe physical and chemical performance that chemical resistance etc. is good.
In the present embodiment, described zirconia thin slice is adhesively fixed with bonding agent and fits tightly in described hookThe outer surface of shape body 12, its upper surface protrudes from the outer surface of described crozier 12, makes the yarn canTo move with very low resistance on online hook, the frictional force between yarn and line hook is down to minimum, therebyAvoid yarn because of the wearing and tearing that unbalance stress produces, kept the original retractility of yarn and elasticity,And ensure 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, and described oxidationZirconium thin slice is by hot pressing, and the conventional methods such as stationary fit are embedded in the outer surface of described crozier 12.
