Description

  TECHNICAL FIELD The present invention relates to a sliding cloth including a fluorocarbon resin fiber suitable as a sliding material. The present invention also relates to a window glass stabilizer made of the sliding fabric.

  Conventionally, a fluorine resin is used by being laminated or coated on the surface layer of a sliding member by making use of its low coefficient of friction. However, in the case of the lamination and coating of the fluorine resin, the fluorine resin film is thin and easily non-adhesive, so it is easy to peel off, and in order to maintain the slidability in the long term, the lamination and coating have to be repeated. In order to eliminate such a defect, the fluorocarbon resin is fiberized and disposed on the surface of the sliding member as a woven or non-woven fabric to improve the friction durability, and further to be combined with the woven or knitted fabric which is easily adhered to other materials. Sliding materials that bond more firmly have been developed.

  For example, Patent Document 1 discloses that a pile fabric made of polytetrafluoroethylene yarn and having a specific napping density is used as an interview member for a window glass stabilizer so that the friction with the glass surface is small and smooth. In addition, there is disclosed a technique in which the glass does not slide and the glass is not marked, and the bulk elastic effect of the pile yarn can provide an excellent steadying effect.

  The window glass stabilizer is attached in the vicinity of the waist opening in the window glass storage body to prevent the vibration of the glass when the window glass is opened and closed. Generally, the glass is viewed from both sides of the window glass It is comprised from the interview member etc. which slide on a surface.

  And such a sliding cloth can be usefully used as an interview member for a window glass stabilizer, a sliding member for a copying machine fixing portion, a vibration-proof rubber, etc., and in particular, usefully used as an interview member for a window glass stabilizer. Can.

  The sliding fabric according to the present invention is a sliding fabric containing a fluorocarbon resin fiber, the sliding fabric having a sliding surface, and a plurality of ridges and a base extending in one direction on the sliding surface. It is characterized in that it is formed alternately.

  In the present invention, the “convex line portion” is a portion where the thick cloth portion of the fabric is formed in a streak shape, and the “base” is a thin cloth portion of the cloth formed in a portion other than the convex streak portion. In addition, “a plurality of ridges and a base extending alternately in one direction are alternately formed” means that the ridge formed in a streak and the base formed between the ridges are replaced with each other. And both are arranged in one direction. Here, in one direction, for example, the ridges adjacent to the ridges do not have to be strictly parallel and arranged in a straight line, and there may be some distortion, and they are generally parallel and arranged in one direction. It should just be.

  The above-mentioned sliding cloth contains a fluorocarbon resin fiber on the sliding surface. The sliding fabric has a sliding surface that is used for sliding, and a plurality of ridges are formed on the sliding surface. The ridges are preferably made of fluorocarbon resin fibers. As a result, the low friction of the ridge portion adhering to the mating material as the sliding surface can be realized. The base may be made of fluorocarbon resin fiber, but is preferably made of other fiber. Thereby, mechanical performance, such as strength of the fabric itself, can be maintained.

  As a method of forming the ridges on the sliding surface, a method of arranging a yarn thicker than other constituent yarns in the direction of forming the ridges, for example, in the case of a fabric, either the warp direction or the weft direction A method in which thick yarns or plural yarns are combined with other constituent yarns only in the direction and a yarn made thicker than the other constituent yarns is woven, and a thin portion is formed into streaks by embossing and relative The embossing method etc. which form a convex streak part and a base are applicable by forming the streaky part which becomes thick. Above all, it is preferable to form the ridges by arranging a thick fluorocarbon resin fiber as a yarn obtained by doubling the thick yarn or a plurality of yarns and making them thicker than other constituent yarns. Thereby, the area ratio between the ridges and the base, and the height of the ridges can be freely controlled.

  The area ratio of the ridge to the base on the sliding surface is preferably in the range of 0.1 to 2, more preferably in the range of 0.3 to 1. If the area ratio is 0.1 or more, only the ridges of the fluorine fiber can be bonded to the mating material to realize low friction performance. If it is 2 or less, only the ridges adhere to the mating material, so the contact pressure with the mating material is high, the difference in static / dynamic coefficient of friction is small, and water can be discharged efficiently, and when sliding contact with the mating member There is no unpleasant noise.

  Here, "the area of the ridges" refers to a projected area in which the sliding surface of the fabric can be in contact with the mating material at a contact pressure of 100 pa within the sliding field. Moreover, "the area of the base" refers to a projected area in which the sliding surface of the fabric can not contact with the mating material at a contact pressure of 100 pa within the sliding field. Furthermore, "the area ratio of the ridges to the base" means (area of ridges / area of base).

  The height of the ridges in the sliding surface is preferably in the range of 0.05 to 2 mm, and more preferably in the range of 0.1 to 1 mm. When the height is 0.05 mm or more, only the ridges of the fluorine fiber can be bonded to the mating material to realize low friction performance. If it is 2 mm or less, the ridges are unlikely to be elastically deformed, and only the ridges adhere to the mating member and the contact area is reduced, the contact pressure becomes high, and the difference between the static and dynamic friction coefficients becomes small and the water efficiently Can be discharged, and it is hard to generate unpleasant noise when sliding contact with the other member.

  Here, "the height of the ridge" refers to the distance from the surface of the base to the top of the ridge.

  Furthermore, in the above sliding surface, the difference between the coefficient of static friction and the coefficient of dynamic friction when sliding in a direction perpendicular to the ridge direction in a wet state is preferably 0.2 or less, more preferably 0.1 or less It is inside. When the difference between the static friction coefficient and the dynamic friction coefficient is 0.2 or less, unpleasant noise does not occur when sliding contact with the other member.

  Here, the "wet state" refers to immersing the friction partner in water for 30 seconds. The "static coefficient of friction" and the "dynamic coefficient of friction" are surface indenters with a moving speed of 100 mm / min and a load of 2.0 kg using a Shinto Chemical Co., Ltd. surface property measuring device Tribogear (TYPE: HEIDON-14DR). (Aspect 10 × 10 mm) By screwing the fabric to the area 10 × 10 mm, slide the glass plate with a surface roughness of 0.8 μm, which is the friction partner, at right angles to the direction of the ridges of the sliding surface of the sliding fabric. It means that static and dynamic coefficient of friction was determined. Furthermore, "the difference between the static friction coefficient and the dynamic friction coefficient" means (static friction coefficient-dynamic friction coefficient).

  Moreover, although other types of yarn constituting the sliding fabric of the present invention may be used alone or in combination of two or more, one type is preferable. Here, one kind is used when the material constituting the fiber is the same. Polymers of the same kind are polymers in which the main repeating units of the polymers are in common, such as nylon 66, polyethylene terephthalates, etc. For example, the combination of homopolymer and copolymer thereof is also acceptable as the same kind of polymer in the present invention Be done.

  When different fibers are used, since there is a difference in expansion performance, it is easier to set the condition at the time of weaving as the type of fibers used is smaller, and wrinkles due to shrinkage difference are less likely to occur on the surface of the fabric during post-processing Passability improves.

  Further, as the form of the sliding fabric of the present invention, although any of woven fabric, knitted fabric and embossing thereof can be applied, woven fabric is preferable because it is preferable that the denseness and the like are high.

  Further, as the structure of the sliding fabric of the present invention, plain weave, twill weave, satin and other weaves can be applied, however, plain weave and twill weave are preferable because the higher the compactness and the strength etc., the better.

  In order to further enhance the durability, it is possible to use the sliding fabric impregnated with a resin. Here, a thermosetting resin or a thermoplastic resin can be used as the resin impregnated. Although not particularly limited, examples of the thermosetting resin include phenol resin, melamine resin, urea resin, unsaturated polyester resin, epoxy resin, polyurethane resin, diallyl phthalate resin, silicon resin, polyimide resin, vinyl ester Resins, etc. and their modified resins, as long as they are thermoplastic resins, vinyl chloride resin, polystyrene, ABS resin, polyethylene, polypropylene, fluorine resin, polyamide resin, polyacetal resin, polycarbonate resin, polycarbonate, polyester, polyamide etc., and further thermoplastic polyurethane, Synthetic rubbers or elastomers such as butadiene rubber, nitrile rubber, neoprene, polyester and the like can be preferably used.

For example, modifiers, plasticizers, fillers, mold release agents, colorants, diluents and the like can be contained. The term "main component" as used herein refers to the component having the largest weight ratio among the components excluding the solvent, and in the case of a resin containing a phenol resin and a polyvinyl butyral resin as main components, It means that the weight ratio is the first and second (in random order) large.

  In the case of using a thermosetting resin as a method of impregnating the sliding fabric with a resin, the thermosetting resin is dissolved in a solvent to prepare a varnish, and knife coating, roll coating, comma coating, gravure A method of impregnating the fabric by coating or the like is generally used.

  In the sliding fabric of the present invention thus obtained, only the ridges adhere to the mating member and the contact area is reduced, so that the contact pressure is increased, and the difference between the static and dynamic friction coefficients is reduced. No unpleasant noise is generated.

  The window glass stabilizer of the present invention is characterized by using the above-mentioned sliding cloth as at least a part of the interview member. As the interview member, it is preferable that the direction in which the ridges in the sliding surface extend and the moving direction of the window glass be at right angles. As a result, the water on the surface of the window glass can be efficiently drained, and even if water droplets adhere to the window glass due to rainfall etc. and the interview member gets wet, it is unpleasant when the glass surface and the interview member slide when opening and closing the window glass.
