Description

  The present invention relates to a plated fiber and a manufacturing method thereof.

  In recent years, for the purpose of increasing strength, reducing weight, and bending resistance, plated fibers obtained by plating tensile strength fibers such as aramid fibers, PBO (poly (p-phenylenebenzobisoxazole) fibers, and polyarylate fibers) have been proposed. In addition, electric wires in which this plated fiber is used as a conductor and covered with an insulator have also been proposed (see, for example, Patent Documents 1 to 3).

  Here, in order to use the plated fiber as the conductor member of the electric wire, the stability of the conductor resistance value is an absolute condition, and it is necessary to perform plating with a uniform film thickness over the entire length of the electric wire. From this point of view, the reel-to-reel method that allows continuous plating rather than the batch method is desirable as a method for plating fibers.

  However, when plating with the reel-to-reel method, the tensile strength fiber is generally weak in abrasion resistance, so it does not come into contact with guides during the plating process, causing feathering and cutting. This causes a problem that the stability of the conductor resistance value is impaired.

  The present invention has been made to solve such a conventional problem, and the object of the present invention is to provide a plated fiber capable of suppressing the possibility that the stability of the conductor resistance value is impaired, and It is in providing the manufacturing method.

The plated fiber of the present invention is a plated fiber obtained by subjecting a tensile strength fiber made of para-aramid fiber, PBO fiber, or polyarylate fiber to metal plating, and between the tensile strength fiber and the metal plating, Abrasion resistance, a resin composed of at least one of tarate, polyethylene naphthalate, urethane, fluorine, polyethylene, polypropylene, polyamide, polyvinyl chloride, polyphenylene falside, polyimide, polyether ether ketone, acrylic, ABS, polycarbonate A resin layer is interposed.

  According to the plated fiber of the present invention, since the abrasion resistant resin layer is interposed between the tensile strength fiber and the metal plating, it is generally prevented that the tensile strength fiber which is weak in abrasion resistance directly contacts the guides. As a result, feathering and cutting of the tensile strength fiber are suppressed. Thereby, possibility that the stability of a conductor resistance value will be impaired can be suppressed.

Moreover, the method for producing a plated fiber of the present invention is a method for producing a plated fiber obtained by performing metal plating on a tensile strength fiber made of para-aramid fiber, PBO fiber, or polyarylate fiber, and the outer periphery of the tensile strength fiber. , Polyethylene terephthalate, polyethylene naphthalate, urethane, fluorine, polyethylene, polypropylene, polyamide, polyvinyl chloride, polyphenylene falside, polyimide, polyether ether ketone, acrylic, ABS, polycarbonate resin The first step of forming the wear-resistant resin layer, and the tensile strength fiber formed with the wear-resistant resin layer in the first step is sent out from the first reel and wound around the second reel. Apply plating by immersing in a plating bath Characterized in that it comprises a step.

  According to this plated fiber, since the abrasion-resistant resin layer is formed on the outer periphery of the tensile strength fiber, it is generally prevented that the tensile strength fiber that is weak in abrasion resistance comes into direct contact with the guides. Cutting is suppressed. In addition, since the tensile strength fiber with the abrasion-resistant resin layer formed is immersed in the plating tank while being fed and wound by both reels, it is easy to make the plating film thickness uniform, which is advantageous in terms of stability of the conductor resistance value. can do. Therefore, the possibility that the stability of the conductor resistance value is impaired can be suppressed.

  ADVANTAGE OF THE INVENTION According to this invention, the plating fiber which can suppress possibility that the stability of a conductor resistance value will be impaired, and its manufacturing method can be provided.

It is sectional drawing which shows the structure of the plating fiber which concerns on embodiment of this invention. It is the schematic which shows the manufacturing method of the plating fiber which concerns on this embodiment.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described with reference to the drawings. FIG. 1 is a cross-sectional view showing a configuration of a plated fiber according to an embodiment of the present invention. As shown in the figure, the plated fiber 1 includes a fiber layer 10, a plated layer (metal plating) 20, and an abrasion-resistant resin layer 30.

  The fiber layer 10 is composed of tensile strength fibers. Here, examples of the tensile strength fiber include para-aramid fiber, PBO (poly (p-phenylenebenzobisoxazole) fiber, polyarylate fiber, and high-molecular polyethylene fiber.

  The plated layer 20 is formed of, for example, an annealed copper wire, a silver plated annealed copper wire, a tin plated annealed copper wire, and a tin plated copper alloy. This plating layer plays the role of a conductor in the sense of an electric wire.

  Such a plated fiber 1 is composed of a fiber layer 10 whose inside is made of a tensile strength fiber. For this reason, the plated fiber 1 is lightweight and has high strength, and is excellent in bending resistance.

  Further, in order to use the plated fiber 1 as an electric wire, it is necessary to make the plating film thickness more uniform from the relationship of the conductor resistance value. For this reason, the reel-to-reel method is adopted in the production of the plated fiber 1 rather than the batch method.

  However, tensile strength fibers generally have a characteristic that they are weak in wear resistance. For this reason, when the plated fiber 1 is manufactured by the reel-to-reel method, the tensile strength fiber comes into contact with the guides, and feathering or cutting occurs. And when this forms the plating layer 20, the stability of a conductor resistance value will be impaired.

  Therefore, in the plated fiber 1 according to this embodiment, the wear-resistant resin layer 30 is interposed between the fiber layer 10 and the plated layer 20. The abrasion-resistant resin layer 30 is made of, for example, polyethylene terephthalate, polyethylene naphthalate, urethane, fluorine, polyethylene, polypropylene, polyamide, polyvinyl chloride, polyphenylene falside, polyimide, polyether ether ketone, acrylic, ABS (Acrylonitrile. Butadiene / Styrene) and at least one of polycarbonate.

  Since such an abrasion-resistant resin layer 30 is formed, it is generally possible to prevent the tensile fibers that are weak in abrasion resistance from coming into direct contact with the guides, and to suppress the feathering and cutting of the tensile fibers. It becomes.

  Next, the manufacturing method of the plated fiber 1 which concerns on this embodiment is demonstrated. FIG. 2 is a schematic view showing a method for manufacturing the plated fiber 1 according to the present embodiment. First, the abrasion resistant resin layer 30 is formed on the fiber layer 10 which is a tensile strength fiber. At this time, the wear-resistant resin layer 30 can be provided by UV irradiation, dipping, or the like.

  Next, as shown in FIG. 2, the tensile strength fiber in which the abrasion-resistant resin layer 30 is provided on the fiber layer 10 is sent out from the first reel 41 and wound around the second reel 42. At this time, a plating tank 43 is provided between the first reel 41 and the second reel 42, and the tensile strength fibers fed from the first reel 41 to the second reel 42 are on the wear-resistant resin layer 30. The plating layer 20 is applied to the surface. Moreover, the reel-to-reel system shown in FIG. 2 makes it easier to form the plating layer 20 on the tensile strength fiber with a more uniform film thickness.

  Further, conventionally, the tensile strength fibers come into contact with the guide member 44 from the first reel 41 to the plating tank 43 and the guide member 45 from the plating tank 43 to the second reel 42, and feathering or cutting occurs. Although it was a cause, in this embodiment, since the abrasion-resistant resin layer 30 is formed on the fiber layer 10, it is hard to generate | occur | produce a feather and a piece.

  Thus, according to the plated fiber 1 which concerns on this embodiment, since the abrasion-resistant resin layer 30 is interposed between the fiber layer 10 and the plating layer 20, the tensile strength generally weak in abrasion resistance The fibers are prevented from coming into direct contact with the guides, and the occurrence of feathering and breakage of the tensile strength fibers is suppressed. Thereby, possibility that the stability of a conductor resistance value will be impaired can be suppressed.

  In addition, according to the method for manufacturing the plated fiber 1 according to the present embodiment, since the wear-resistant resin layer 30 is formed on the outer periphery of the fiber layer 10, the tensile strength fiber generally weak in wear resistance is in direct contact with the guides. This prevents the tensile strength fibers from falling and being cut off. Further, since the tensile strength fiber on which the wear-resistant resin layer 30 is formed is immersed in the plating tank 43 while being fed and taken up by the reels 41 and 42, the plating film thickness is easily uniformed and the conductor resistance value is stable. This can be advantageous. Therefore, the possibility that the stability of the conductor resistance value is impaired can be suppressed.

  As described above, the present invention has been described based on the embodiment, but the present invention is not limited to the above embodiment, and may be modified without departing from the gist of the present invention.

  For example, in the above-described embodiment, it was emphasized that the tensile strength fiber is weak in abrasion resistance. However, even if a tensile strength fiber excellent in abrasion resistance is developed by future technical improvement, the present invention can be applied to this tensile strength fiber. Needless to say. This is because even in this case, the wear-resistant resin layer 30 can reduce the possibility of feathering or breaking of the tensile strength fiber.
