Description
Technical field
The present invention relates to a kind of two-layer fabric containing polytetrafluoroethylene fibre and uses thereof.
Background technology
Traditional sliding bearing is generally all made by metal material, and this class bearing is limited to use in some occasion, such as underwater operation.Owing to adding lubricating oil in traditional bearing, in order to prevent the phenomenon such as leakage of oil, oil dripping, thus significantly limit traditional bearing and can not use the application in the occasion of lubricating oil.Therefore, the necessary bearing developing a kind of oil-free lubrication.Along with the development of technology, people have developed the pure polyflon of a kind of employing as press face, are applied in Nonlubricated bearing.But, in actual use, because the ABRASION RESISTANCE of polyflon is bad, cause the wearing and tearing of sliding bearing comparatively serious, substantially reduce its service life.Particularly under high capacity operation, the surface self-lubricating Wear-resistant plastic bed of material (polyflon layer) is easy to be worn through, and causes traditional bearing or axle just to there will be the phenomenon of breaking, and in severe cases, even can threaten the life security of operating personnel.Although have developed at present a kind of adopt polytetrafluoroethylene (PTFE) to become with other fiber interweavings woven and be applied in sliding bearing, but this kind of woven just meets the good requirement of sliding, can not meet for the caking property between fabric and metal axle sleeve.When bearing operation, this fabric is just easily peeled off by external force, thus causes the inefficacy of self-lubricating bearing.
As disclosed a kind of bearing self-lubricating composite liner and preparation method thereof in Chinese publication CN 1O2535167A, this fabric is the fibrous intertexture by PTFE fiber and other fibrages of at least one, and has impregnated material at intertexture Surface coating.Although it is high that this composite has intensity, the feature that coefficient of friction is little, but this invention adopts phenolic resins, molybdenum bisuphide, nano aluminium oxide, superfine powder of polytetrafluoroethylene is mixed with impregnated material, then intertexture surface is coated to, obtained PTFE composite, because PTFE composite material surface tension force is little, its tension force is only 0.019N/m, it is the minimum a kind of solid material of current surface tension, be difficult to paste with other materials, so adopt binding agent by above-mentioned PTFE Composite Bonded in steel surface time, by after external force in motion process, easily make to peel off between composite and metal surface, thus cause the moving components such as self-lubricating bearing to lose efficacy.
Summary of the invention
The object of the present invention is to provide that a kind of coefficient of friction is little, peel strength is high, stress deformation is little, technique is simply containing two-layer fabric and uses thereof of polytetrafluoroethylene fibre.
Technical solution of the present invention is as follows: the two-layer fabric containing polytetrafluoroethylene fibre of the present invention, comprise top layer and nexine, this two-layer fabric is fibrage access node all-in-one-piece polytetrafluoroethylene fibre layer and other fibers formed by binding place, the fiber number wherein forming the fiber of above-mentioned polytetrafluoroethylene fibre layer is 50 ~ 1400dtex, the twist is 0 ~ 800t/m, and other fibers are one or more in cotton, polyester, polyamide, polyphenylene sulfide.If adopt polytetrafluoroethylene fibre and other fiber interweavings to obtain individual layer intertexture, although this woven has taken into account sliding and close-burning feature, if when this woven is applied to bearing, interlacing point quantity due to woven one side is all not the quantity of polytetrafluoroethylene (PTFE) interlacing point, so the self lubricity of polytetrafluoroethylene (PTFE) excellence can not be given full play to, but also there is the shortcoming of adherence difference between this woven and metal surface.If the fiber number of polytetrafluoroethylene fibre is less than 50dtex, because fiber is too thin, weave difficulty, and the cloth abrasion consumption obtained also can be caused to be deteriorated; If the fiber number of polytetrafluoroethylene fibre is greater than 1400dtex, fabric friction coefficient can be caused to become large, and when being applied to bearing, polytetrafluoroethylene fibre layer is not good as rubbing surface lubricant effect.The polytetrafluoroethylene fibre twist forming this fabric is 0 ~ 800t/m.If the polytetrafluoroethylene fibre twist forming this fabric is greater than 800t/m, owing to being applied with the larger twist, along the length direction of long filament, each monofilament there will be strong torsion phenomenon, therefore obtained fabric will produce very large frictional force, affect the self-lubricating effect in this fabric abrasive face, and arrangement between the larger each monofilament of the twist is tightr, when the polytetrafluoroethylene fibre layer in two-layer fabric is applied to bearing etc. as rubbing surface, because the monofilament forming fabric is concentrated stressed, very easily rubbed, cause the wearing and tearing of sliding bearing comparatively serious simultaneously, substantially reduce its service life.
In two-layer fabric containing polytetrafluoroethylene fibre of the present invention, other fibers are one or more in cotton, polyester, polyamide, polyphenylene sulfide.The fibrage adopting above-mentioned fiber to obtain is as the top layer of two-layer fabric and nexine, and when being applied to the moving components such as bearing, this layer is pasted on bearing surface, have good adherence, peel strength is high, also not easily peels off under the service condition of high load capacity.This two-layer fabric can resist certain deformation in friction process simultaneously, and namely two-layer fabric stress deformation of the present invention is little, is conducive to the proper motion maintaining mechanical part.Consider the adherence between metal and stress deformation aspect, the preferred cotton fiber of other fibers above-mentioned and polyphenylene sulfide fibre.
The fibrage that the fibrage that the structure of the two-layer fabric containing polytetrafluoroethylene fibre of the present invention is formed as top layer, other fibers for polytetrafluoroethylene fibre layer is formed as nexine or other fibers as top layer, polytetrafluoroethylene fibre layer as nexine.When being applied to the moving components such as bearing by the two-layer fabric that specific weaving method is obtained, polytetrafluoroethylene fibre layer is as frictional layer, the fibrage that other fibers are formed is pasted on the moving component surfaces such as bearing as following layer, there is good adherence, peel strength is high, also not easily peels off under the service condition of high load capacity.
The table organization of the two-layer fabric containing polytetrafluoroethylene fibre of the present invention is plain weave, twill, satin weave and alternative construction thereof, is innerly organized as plain weave, twill, satin weave and alternative construction thereof.Preferred twill or satin weave and alternative construction thereof.Adopt twill or satin weave and alternative construction thereof, fabric face has certain floating length, can cover the fiber of access node effect preferably.Thus make this two-layer fabric play best performance, and the polytetrafluoroethylene fibre layer of top layer or nexine, the coefficient of friction of this layer is low, has good self-lubricating property; Another layer is one or more other fibrages formed in cotton, polyester, polyamide, polyphenylene sulfide, has higher peel strength.
The access node method of the two-layer fabric containing polytetrafluoroethylene fibre of the present invention is back warp access node, shows through access node, access node through access node, binding pick access node or associating access node.When knitting top layer, back warp is mentioned and is interweaved form access node with table latitude, and this access node method is called back warp access node, or title " under connect " access node method; When knitting nexine, showing interweaves through decline and back weft forms access node, and this access node method is called that table is through access node, or claims " above connecing down " access node method; Adopt additional access node through interweaving with table back weft, two-layer fabrics is coupled together, and this access node method is called that access node is through access node method; Warp yarns in adopting additional binding pick and showing, two-layer fabrics is coupled together, and this access node method is called binding pick access node; When knitting table latitude, back warp is mentioned and is interweaved with table latitude, and when knitting back weft, showing interweaves through decline and back weft forms access node jointly, and this access node method is called associating access node.Wherein preferably table is through access node, back warp access node or associating access node, because these three kinds of access node methods use the warp thread of self or weft yarn to carry out access node, weaving process is comparatively simple, easy to operate.More preferably combine access node, reach unanimity because table, back warp can be made to contract, and access node two-layer in table is also more firm.And adopt access node through access node and binding pick access node method, just need to adopt additional wire access node, machine work can be made complicated.In addition, adopt access node when access node method, because access node is comparatively large through crimp, must dual beams be adopted.When adopting binding pick access node method, the loom of the weft insertion device can changing multiple weft yarn must be used to weave.Therefore, access node is applied less through access node and these two kinds of methods of binding pick access node.
Two-layer fabric containing polytetrafluoroethylene fibre of the present invention, containing 30 ~ 196 monofilament in described polytetrafluoroethylene (PTFE) yarn.If monofilament radical is less than 30, when two-layer fabric contacts with mechanical moving element, odd number radical is fewer, and the abrasion performance of gained fabric will be deteriorated; If monofilament radical is more than 196, spinning difficulty will be increased like this, cause production cost to increase.
In two-layer fabric containing polytetrafluoroethylene fibre of the present invention, the warp of polytetrafluoroethylene fibre layer, the broadwise coefficient of sliding friction are below 0.10, and preferably less than 0.08, more preferably less than 0.06.If the warp of polytetrafluoroethylene fibre layer, the broadwise coefficient of sliding friction are higher than 0.10, illustrate that the self-lubricating effect of this fabric is not remarkable, when fabric contacts with mechanical moving element, frictional force is larger, the normal operation of frictional metal parts can be affected, fabric can be easy to be worn, thus causes the wearing and tearing of sliding bearing comparatively serious, substantially reduces its service life.
The fibrolaminar peel strength that in two-layer fabric containing polytetrafluoroethylene fibre of the present invention, other fibers are formed is greater than 0.5N/mm.If peel strength is lower than 0.5N/mm, the adhesive property of fabric and metal is deteriorated, and easily peels off, cause the inefficacy of mechanical moving element during work by after external force.
