Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to textiles used for carpets, tapestries, hanging scrolls, wall coverings, donkeys, etc., and particularly relates to textiles whose colors can be changed.

[Prior Art] Generally, methods of expressing color in textiles include weaving pre-dyed threads into a certain pattern, or adding color to white fabric. In such a method, to prevent color fading during subsequent washing, etc.
I try to dye it solidly.

[Problems to be Solved by the Invention] However, in the conventional means described above, once a color is applied, the color is fixed and cannot be changed. For this reason, there has been a limit to the color expression in textiles, and in terms of color, there has been a limit to the means for improving the design of textiles. In addition, especially when it comes to textiles for display, it is easy to get bored if the colors do not change, and the textiles often have to be replaced with ones of a different color.

The present invention was made in view of the above circumstances, and aims to provide a fabric whose color can be changed to further improve the design of the fabric.

[Means for Solving the Problems] The present invention involves weaving an optical fiber having a part or all of a portion without a cladding layer as either the warp or the weft thread, and at the same time, one end of the optical fiber is The part of the fabric that protrudes outside the woven structure and does not have a cladding layer forms a certain pattern on the surface of the fabric, and near one end of the optical fiber there is a pattern extending toward this end. A light-emitting device that emits light is installed between the light-emitting device and the one end, and is semi-transparent and colored in a plurality of colors. A rotating body that changes the color of the transmitted light is installed, and the rotating body is constructed of a fabric to which a rotating means for rotating the rotating body is attached.

[Example] FIGS. 1 to 5 are diagrams showing an example of the present invention.

In these figures, 10 is a rectangular woven fabric.

The fabric 10 is composed of warp threads and weft threads, and the warp threads are woven with nylon threads and threads, and the weft threads are nylon threads and optical fibers 20. The optical fiber 20 is composed of a core 21 and a cladding layer 22 (FIG. 3). The optical fiber 2
0 has no cladding layer 22 at a certain location in the length direction, and consists only of the core 21 at this location (FIG. 4).
The portion consisting only of the core 21 is the surface 1 of the fabric 10.
It is formed at a position constituting a zigzag-shaped handle 11 at 0a (FIG. 1). As a result, the portion not having the cladding layer becomes the surface 10 of the fabric 10.
A is configured to form a certain pattern. In order to obtain the above-mentioned optical fiber 20 without the cladding layer 22, the optical fiber 20 from which the cladding layer 22 of the handle 11 portion has been removed may be woven into the fabric, or the optical fiber 20 having the cladding layer 22 may be woven into the fabric. Later, the cladding layer 22 on the handle 11 may be removed by chemical treatment. The textile 10 is supported in a rectangular shape by a substrate (not shown).

One end 20a and the other end 2 of the optical fiber 20
0b are both protruded from both ends of the fabric 10 to the outside of the woven structure. The one end portion 20a and the other end portion 20b are connected to the back surface 1 of the fabric 10.
On the 0b side, each is combined into two,
They are bundles 21a, 21b, 22a, and 22b.

The bundles 21a, 21b and the bundles 22a, 22b
There are disks (rotating bodies) 30 and 3 on the tip side, respectively.
1 is provided. These disks 30, 31
The disc 30 is made of a transparent material, and as shown in FIG. It's summery. That is, disk 3
0 and 31 are rotated so as to change the color of transmitted light that passes through these disks 30 and 31 from light emitting devices 50 and 51, which will be described later, toward the end of the optical fiber 20. It is composed of

As shown in FIG. 5, a shaft 40 is disposed at the center of the discs 30, 31 in a direction perpendicular to the discs 30, 31, and is fixed to the discs 30, 31. One end of this shaft 40 is connected to a motor (rotating means) not shown, and the disks 30, 31 are rotated in the direction of the arrow in FIG. 5 by the driving force of the motor.

The bundles 21a and 21b of the disks 30 and 31
Light emitting devices 50 and 51 are provided at positions opposite to the positions of the bundles 22a and 22b, respectively. Thereby, the disc 30 and the disc 31 are respectively disposed between the light emitting devices 50 and 51 and the one end 20a and the other end 20b of the optical fiber 20. These light emitting devices 50,
51 are configured such that the disks 30 and 31 sides become light emitting parts, and the light 50a and 51
The configuration is such that the light a is directed toward the disks 30 and 31. The lights 50a and 51a are connected to the disk 3.
0 and 31, and is irradiated onto the ends 20a and 20b of the optical fiber 20.
The intensity of these lights 50a and 50b is the same as that of the optical fiber 20.
The illuminance is sufficient for transmitted light to pass through the interior. The light emitting devices 50, 51 are configured to emit light 50a,
It is preferable that the structure is such that 51a is difficult to diffuse.

Next, a method of using the fabric configured as described above will be explained.

First, the light emitting devices 50 and 51 are turned on to irradiate light 50a and 51a in the direction of the disks 30 and 31.
Then, the lights 50a and 51a pass through the disks 30 and 31 and are irradiated onto the ends 20a and 20b of the optical fiber 20. At this time, the lights 50a, 5
At the time when 1a passes through the disks 30 and 31,
When the light 50a, 51a passes through any of the colored portions marked on the disks 30, 31, it becomes light having a certain color. The lights 50a and 51a irradiated as described above pass through the optical fiber 20 and reach the pattern 11 portion of the fabric 10. During this time, since the lights 50a and 51a are transmitted through the optical fiber 20, it is possible to prevent the lights 50a and 51a from attenuating. Since the handle 11 does not have the cladding layer 22, the light 50a, 51a that reaches the handle 11 is diffused from the core 21 to the outside. That is, the optical fiber 20
The presence of the cladding layer 22 prevents light from diffusing to the outside, but according to the fabric 10 of this example, there is a portion without the cladding layer 22, so light can be transmitted from this portion. , part of the transmitted light can be diffused to the outside. In this way, it is possible to supply the lights 50a and 51a to the outside and make a certain color (including non-colored light) appear. Here, the light is 50% at the handle 11 part.
When the light 51a interferes with the light 51a, the color changes to another color in that area, thereby improving the design of the fabric 10.

Further, in this embodiment, since the disks 30 and 31 are rotated in the direction of the arrow by the shaft 40, the disks 30 and 31 are rotated by rotating the shaft 40.
By rotating the discs 30 and 31, the colors of the lights 50a and 51a that pass through the discs 30 and 31 can be sequentially and arbitrarily changed over time.

Therefore, according to the fabric 10 of this embodiment, the light diffused from the portion consisting only of the core 21, which constitutes the predetermined pattern 11, is expressed by sequentially and arbitrarily changing different colors. It is possible,
The design of the textile 10 can be improved, and its product value can be dramatically increased.

Furthermore, in this embodiment, the shaft 40 can also be rotated at a constant period. In this case, since the colors of the lights 50a and 51a that pass through the disks 30 and 31 can be changed periodically, the color of the pattern 11 can be changed periodically, and the design of the fabric 10 can be improved. Further improvements can be made.

Furthermore, in this embodiment, the one end 20a and the other end 20b of the optical fibers 20 are each put together into two bundles 21a, 21b, 22a, and 22b, so that the discs are shaped according to the position of each bundle. Colored light 50a, 51a at 30, 31 can be captured by optical fiber 20. At this time, the bundles 21a, 21b, 22a, 22b are
When the disks 30, 31 are at the intermediate position between the color divisions, the respective bundles 21a, 21
Depending on the position of the ends 20a, 20b of the optical fiber 20 at the ends 20a, 22b, two different colors can be captured. In this case, even more diverse colors can be expressed in the pattern 11 portion.

Note that in the above embodiment, the optical fiber 20
Although both the one end 20a and the other end 20b were made to protrude from both ends of the textile 10 to the outside of the woven structure, they may be made to protrude from the surface 10a of the textile 10 to the outside. In short, it is sufficient that it protrudes outside the weave structure of the fabric 10.

Further, in the above embodiment, the optical fiber 20
One end 20a and the other end 20b are each put together into two on the back side 10b side of the fabric 10 to form bundles 21a, 21b, 22a, 22b, but the number is not limited to two, and one may be used. , there may be three or more.

Further, in the above embodiment, the optical fiber 20 is woven as the weft of the fabric 10, but it may be woven as the warp, or as both the weft and the warp.

Further, in the above embodiment, both one end 20a and the other end 20b of the optical fiber 20 were made to protrude from both ends of the woven fabric 10 to the outside of the woven structure. It may also be something that stands out. In short, any configuration that can supply light to the optical fiber 20 may be used.

Further, in the above embodiment, the optical fibers are woven one by one, but a plurality of optical fibers may be woven into one yarn.
In this case, each optical fiber 20 may not have the cladding layer 22 at different locations. This has the advantage that more complex color expression can be performed.

[Effects of the invention] The present invention incorporates an optical fiber having a part or all of a portion without a cladding layer as either the warp or the weft thread, and also connects one end of the optical fiber to the outside of the woven structure. The protruding portion of the fabric that does not have a cladding layer forms a certain pattern on the surface of the fabric, and near one end of the optical fiber, light is irradiated toward this one end. A light-emitting device is installed between the light-emitting device and the one end, which is semi-transparent and colored in a plurality of colors, and when rotated, transmitted light is transmitted from the light-emitting device to the one end. A rotating body that changes the color of the fabric is installed, and a rotating means for rotating the rotating body is attached to the rotating body.

Therefore, when the light emitted from the light emitting means toward one end of the optical fiber passes through the rotating body,
Depending on the color applied to the rotating body, the rotating body itself has a unique color.

Therefore, according to the fabric of the present invention, by rotating the rotating body using the rotating means, the color of the light transmitted through the rotating body and irradiated to the end of the optical fiber can be changed over time as desired. The color can be changed to

In this way, the light irradiated to the end of the optical fiber is diffused outward from the part of the optical fiber that does not have a cladding layer, so according to the fabric of the present invention, different colors can be seen in the patterned part. It can be expressed by changing the light arbitrarily, dramatically improving the design of textiles and increasing their product value.
