Description

The present invention relates to plated fibers.

For example, when plating a fiber reel-to-reel, the fiber is placed between the supply reel and the take-up reel through the plating tank, and the fiber is plated while flowing from the supply reel to the take-up reel. Plating is applied in a tank. When plating is applied in this manner, if the fibers are twisted, plating unevenness occurs. Therefore, the fibers are installed so as not to be twisted between the supply reel and the take-up reel.

Here, a twist detection device for detecting twist of a rectangular wire has been proposed (see Patent Document 1, for example). This twist detection device magnetizes one surface of the flat wire to S pole and the other surface to N pole, and detects the occurrence of twist by detecting this magnetization state.

JP-A-2001-91207

However, although the twist detection device described in Patent Document 1 can detect twists in a conductor such as a rectangular wire, it is difficult to magnetize fibers before plating. Fiber twist cannot be detected. Therefore, it was necessary to visually detect the twist of the fiber before plating. However, there is a limit to visual detection, and it is difficult to determine the twist especially when the fibers are fine.

The present invention has been made to solve such conventional problems, and an object of the present invention is to provide a plated fiber capable of suppressing uneven plating due to twisting.

The plated fiber according to the present invention has a fiber portion made of at least one of a tensile strength fiber and a carbon fiber, and a metal plating portion applied on the fiber portion, and has a flattened plated fiber portion. a flat cord portion that is continuous with the plated fiber portion and is provided on one end side of the plated fiber portion and has a flat shape, and the flat cord portion has different colors on one side and the other side in the flat width direction. The colored portion is continuous in the longitudinal direction.

According to the present invention, the flat cord portion has a continuous flat cord portion on one end side of the plated fiber portion, and the flat cord portion has colored portions of different colors on one side and the other side in the flat width direction, which are continuous in the longitudinal direction. As for the part, it is possible to easily find the twist by coloring the one side and the other side. Therefore, the flat cord portion can be relatively easily installed between the reels without being twisted. It is possible to form a twist-free plated fiber portion that is continuous with the flat cord portion. Therefore, it is possible to provide a plated fiber capable of suppressing uneven plating due to twisting.

Further, the plated fiber according to the present invention has a fiber portion made of at least one of a tensile strength fiber and a carbon fiber, and a metal plating portion applied on the fiber portion, and has a flattened plated fiber portion. and a flat cord portion that is continuous with the plated fiber portion and is provided on one end side of the plated fiber portion and has a flat shape, and the flat cord portion is provided on one side and the other side in the flat width direction, and the A colored portion having a different color from the central width portion between one side and the other side is continuous in the longitudinal direction.

According to this invention, the flat cord portion is provided with a continuous flat cord portion on one end side of the plated fiber portion, and the flat cord portion has a colored portion with a color different from that of the central portion of the width on one side and the other side in the flat width direction and is continuous in the longitudinal direction. Therefore, it is possible to easily detect twisting of the flat cord portion by coloring portions on one side and the other side. Therefore, the flat cord portion can be relatively easily installed between the reels without being twisted. It is possible to form a twist-free plated fiber portion that is continuous with the flat cord portion. Therefore, it is possible to provide a plated fiber capable of suppressing uneven plating due to twisting.

The fiber used for the colored portion may have any fiber diameter and physical properties as long as the color can be identified.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described below along with preferred embodiments. It should be noted that the present invention is not limited to the embodiments described below, and can be modified as appropriate without departing from the gist of the present invention. In addition, in the embodiments shown below, there are places where illustrations and explanations of some configurations are omitted, but the details of the omitted technologies are as long as there is no contradiction with the contents explained below. Needless to say, well-known or well-known techniques are applied as appropriate.

FIG. 1 is a plan view showing the configuration of plated fibers according to an embodiment of the present invention. As shown in FIG. 1, the plated fiber 1 according to the present embodiment includes a plated fiber portion 10 and a flat cord portion 20. As shown in FIG. The plated fiber portion 10 (especially the fiber portion 11 to be described later) and the flat cord portion 20 are connected via a joint portion J, and both form a continuous filamentous body.

FIG. 2 is a cross-sectional view showing the plated fiber portion 10 shown in FIG. As shown in FIG. 2, the plated fiber portion 10 includes a fiber portion 11 and a metal plated portion 12 and has a flat shape.

In this embodiment, the fiber portion 11 is composed of at least one of tensile strength fiber and carbon fiber, for example. Tensile fibers are, for example, aramid fibers, polyarylate fibers, and PBO fibers. In addition, the tensile strength fiber is not limited to these three types, and may have tensile strength equivalent to or higher than these. Further, the fiber portion 11 may be composed of two or more of tensile strength fibers and carbon fibers.

The metal plating portion 12 is a metal layer provided on the fiber portion 11 . The metal plated portion 12 is made of a metal having a high electrical conductivity such as copper, and is provided on the fiber portion 11 by an electroplating process or an electroless plating process.

Although the fiber portion 11 is composed of six fibers in FIG. 2, the number of fibers is not particularly limited to this. In addition, although the six fibers are arranged in one row, each fiber does not have to be arranged in one row.

FIG. 3 is an enlarged plan view of the flat cord portion 20 shown in FIG. The flat cord portion 20 shown in FIG. 3 is a fibrous body that is continuous with the plated fiber portion 10 shown in FIG. ing. The flat string portion 20 is formed into a flat shape by weaving threads, and colored portions of different colors are continuous in the longitudinal direction on one side and the other side in the flat width direction.

More specifically, the flat cord portion 20 is constructed by weaving together a first color thread (colored portion) 21, a second color thread (colored portion) 22, and a third color thread . The first color thread 21 is arranged along the longitudinal direction on one side of the flat cord portion 20 . The second color thread 22 is arranged along the longitudinal direction on the other side of the flat cord portion 20 . The first color threads 21 and the second color threads 22 are arranged in bundles having different colors and having a thickness or a number of threads that are easily visible by the operator.

The third color thread 23 is arranged in the width center portion between one side and the other side of the flat cord portion 20, and is composed of a color different from that of the first color thread 21 and the second color thread 22. . By configuring the third color threads 23 in a color different from that of the first color threads 21 and the second color threads 22 , the operator can more easily distinguish between the first color threads 21 and the second color threads 22 .

4 is a plan view showing the twisted state of the flat cord portion 20 shown in FIGS. 1 and 3, (a) showing an example of the first twist, and (b) showing the second twist shows an example of As shown in FIGS. 4A and 4B, when the flat cord portion 20 is twisted in any of the examples, the positions of the first color thread 21 and the second color thread 22 are exchanged. Thereby, the operator can visually determine the twist based on the change of color.

In the above description, the flat cord portion 20 has a configuration in which the first color thread 21 and the second color thread 22 of different colors are woven, but this is not restrictive, and after being woven into a flat shape with threads of the same color, , one side and the other side may be retrofitted (colored) with different colors.

Furthermore, in this embodiment, the flat cord portion 20 preferably has one or more of the following configurations.

First, it is preferable that the flat cord portion 20 has a strength equal to or higher than that of the fiber portion 11 . This is because, for example, it is possible to make it difficult to cut the flat cord portion 20 between the supply reel 101 and the take-up reel 102, which will be described later.

Secondly, it is preferable that the flat cord portion 20 has an elongation rate equal to or lower than that of the fiber portion 11 . This is because, for example, it is possible to reduce the possibility that the flat cord portion 20 will be greatly stretched between the supply reel 101 and the take-up reel 102 to be described later and will be separated from the rollers 104 to 106, for example.

FIG. 5 is a schematic diagram showing the plating method according to the present embodiment, and shows the state of plating by electroplating. As shown in FIG. 5, the plating apparatus 100 schematically includes a supply reel 101, a take-up reel 102, a plating tank 103, rollers 104-106, and copper plates 107,108.

In this embodiment, first, a filamentary body having a flat cord portion 20 continuous to the fiber portion 11 is created. Of these, the flat cord portion 20 is installed between the supply reel 101 and the take-up reel 102 . At this time, the flat cord portion 20 is installed between the supply reel 101 and the take-up reel 102 so as not to be twisted. In particular, since the flat cord portion 20 according to the present embodiment has the above configuration, it can be installed relatively easily without being twisted even visually.

After that, the filamentous body is electroplated in the plating tank 103 while being wound up by the take-up reel 102 . As for electroplating, when the wire passes through the plating bath 103, the copper ions of the copper plates 107 and 108 move toward the power supply rollers 104 and 106 via the plating solution, thereby applying the electroplating onto the fiber portion 11. be.

At this time, according to the plating method according to the present embodiment, since the flat cord portion 20 is not twisted, the fiber portion 11 is also not twisted. , the uneven plating caused by the contact failure caused by the twisted portions being positioned on the power supply rollers 104 and 106 can be prevented.

In the example shown in FIG. 5, the electroplating process has been described as an example, but the present invention is not limited to this, and the same applies to electroless plating process.

In this way, according to the plated fiber 1 according to the present embodiment, the flat cord portion 20 continuous to one end side of the plated fiber portion 10 is provided, and the flat cord portion 20 has different colors on one side and the other side in the flat width direction. Since the first color thread 21 and the second color thread 22 are continuous in the longitudinal direction, the flat cord portion 20 is twisted by the first color thread 21 and the second color thread 22 on one side and the other side. can be easily discovered. As a result, the flat cord portion 20 can be relatively easily installed between the reels without being twisted, and the fiber portion 11 continuous with the flat cord portion 20 is allowed to flow between the reels without such twisting. Thus, it becomes possible to form the plated fiber portion 10 that is continuous with the flat cord portion 20 and has no twist. Therefore, it is possible to provide the plated fiber 1 capable of suppressing uneven plating due to twisting.

Further, since the flat cord portion 20 has a strength higher than that of the fiber portion 11, the flat cord portion 20 can be made difficult to break between the supply reel 101 and the take-up reel 102, for example.

In addition, since the flat cord portion 20 has an elongation rate equal to or lower than the elongation rate of the fiber portion 11, for example, the flat cord portion may be greatly stretched between the supply reel 101 and the take-up reel 102, and the rollers 104 to 106 may detach. can be reduced.

The present invention has been described above based on the embodiments, but the present invention is not limited to the above embodiments, and modifications may be made without departing from the scope of the present invention, and well-known and publicly known techniques may be used. May be combined.

For example, in the above embodiment, the plated fiber portion 10 is directly connected to the other end of the flat cord portion 20 as shown in FIG. may FIG. 6 is a plan view showing a modification of the plated fiber according to the embodiment of the invention.

As shown in FIG. 6, in the plated fiber 2 according to the modification, a fiber portion 11 having no metal plated portion 12 is connected to one end of the plated fiber portion 10, and a flat cord is connected to one end of the fiber portion 11 via a joint portion J. 20 is connected. Such a plated fiber 2 can be manufactured, for example, by energization timing in electroplating. That is, a filament body in which the flat cord portion 20 and the fiber portion 11 are integrated is installed between the supply reel 101 and the take-up reel 102, and a certain filament body is wound on the take-up reel 102, It is obtained by starting electroplating (energization) after some of the fiber portions 11 have left the plating tank 103 (especially after passing the power supply roller 106 on the downstream side). Thus, in the plated fiber 2 according to this embodiment, the plated fiber portion 10 and the flat cord portion 20 may not be directly connected, and an inclusion may exist between them.

Furthermore, in the above-described embodiment, the plated fiber 1 has the first color thread 21 arranged on one side of the flat cord portion 20 and the second color thread 22 arranged on the other side, as shown in FIG. extends continuously in the longitudinal direction, but it is not limited to this and may be as shown in FIG.

FIG. 7 is a plan view showing a second modification of the plated fiber according to the embodiment of the invention. Note that some symbols are omitted in FIG.

As shown in FIG. 7, in the plated fiber 3 according to the second modification, the first color thread 21 and the third color thread 23 are alternately arranged on one side of the flat cord portion 20, and the first color thread 21 is intermittently continuous in the longitudinal direction. Similarly, in the plated fiber 3, the second color thread 22 and the third color thread 23 are alternately arranged on the other side of the flat cord portion 20, and the second color thread 22 is intermittently continuous in the longitudinal direction. It has become. Thus, the flat cord portion 20 of the plated fiber 3 according to the present embodiment is not limited to the case where the first color thread (colored portion) 21 and the second color thread (colored portion) 22 are continuous without a break, but intermittently may be continuous.

In FIG. 7, the first color thread 21, the second color thread 22, and the third color thread 23 are woven into a substantially arrowhead shape facing one end, but the present invention is not limited to this.

FIG. 8 is a plan view showing a third modification of the plated fiber according to the embodiment of the invention. As shown in FIG. 8, in the plated fiber 4 according to the third modification, the first color thread 21 and the second color thread 22 may be of the same color. In this case, the first color thread 21 and the second color thread 22 have a color different from that of the third color thread 23 positioned at the center of the width.

FIG. 9 is a plan view showing the twisted state of the flat cord portion shown in FIG. 8, (a) showing a first twisting example, and (b) showing a second twisting example. ing. As shown in FIGS. 9(a) and 9(b), in any case, when the flat cord portion 20 is twisted, the continuity of the third color thread 23 is lost. That is, when there is no twist, the third color thread 23 is continuous in the longitudinal direction, but when twisted, the first color thread 21 and the second color thread 22 divide the third color thread 23. located like As a result, the third color thread 23 becomes discontinuous in the longitudinal direction. By confirming that the third color thread 23 is not continuous in the longitudinal direction, the operator can visually determine the twist.

Furthermore, although the first colored thread 21, which is the colored portion, is positioned at one side end of the flat cord portion 20, it is not limited to the one side end and may be positioned slightly inside the one side end. Similarly, the second color thread 22 is also positioned at the other side end of the flat cord portion 20, but it is not limited to the other side end and may be positioned slightly inside the other side end.

In addition, the first color thread 21, the second color thread 22, and the third color thread 23 may be used as they are, or may be colored with some kind of pigment or the like. Further, for example, only the first color thread 21 may be knitted to form the flat cord portion 20, and at least one of one side and the other side of the flat cord portion 20 may be colored.
