Description

  TECHNICAL FIELD The present invention relates to a fabric woven with an outer-surface-emitting optical fiber, a light-emitting device including the woven fabric, and a clothing apparel including the light-emitting device. Related to clothing and apparel.

  An optical fiber is composed of a core layer that transmits light and a cladding layer that prevents light leakage, and has the property of transmitting light incident from one end to the other end. Application to is actively performed.

  In recent years, in the field of apparel and apparel (hereinafter simply referred to as “apparel and the like”), high-fashion apparel that has an unprecedented aesthetic appearance, and wearer's visibility is higher than before. There is an increasing demand for apparel that can be enhanced, and in order to meet the demands of such customers, the development of products that use the properties of optical fibers is aimed at using the visual effect of light emission. For example, a light-emitting decorative fabric (Japanese Patent Laid-Open No. 6-33338) in which an optical fiber is woven has been proposed.

  This light-emitting decorative fabric uses an optical fiber as part of a warp, and uses a wire that is more flexible than the optical fiber as a weft, and these warps and wefts are woven by plain weave or twill. By using this as a material for clothing, etc. as described above, a visual effect different from that of clothing, etc., in which ordinary fabrics are used, is exhibited, and has an excellent aesthetic appearance. Become.

JP-A-6-33338

  However, the conventional light emitting decorative fabric has the following problems.

  That is, in the light-emitting decorative fabric, as shown in FIG. 9, a gap is inevitably formed on the side of the woven optical fiber K due to the nature of the fabric. And, since the gap is formed in this way, for example, when an external force is applied to the optical fiber K, the optical fiber K is moved in a direction parallel to the weft F (arrow direction in the figure). In other words, it is inevitable that the position is shifted, and as a result, the appearance of the fabric is deteriorated, or an abnormal load is applied to the weft F and the optical fiber K, and these are damaged. The visual effect of light emission cannot be fully exhibited. In particular, when this light-emitting decorative fabric is used for clothing or the like, the above problem becomes extremely serious because an external force caused by movement of the wearer or contact with a person or an object is likely to act.

  The present invention has been made in view of the above circumstances, a fabric capable of preventing the displacement of the optical fiber and sufficiently exhibiting the visual effect of light emission, a light-emitting device including the fabric, and the light emission The purpose is to provide clothing and apparel with equipment.

The present invention for solving the above problems is as follows.
It is a fabric woven with an external light-emitting optical fiber,
A base made of warp and weft, with a storage groove formed,
An optical fiber disposed in the storage groove,
The storage groove is formed along a direction that opens on the surface side of the base and is parallel to the warp,
The weft is woven so as to straddle the optical fiber,
The said optical fiber concerns on the textile fabric woven so that a part of outer surface may be exposed.

  The outer surface-emitting optical fiber in the present invention is an optical fiber in which light incident on the core layer from one end surface leaks from the outer surface through the quad part. For example, the outer surface of the optical fiber is physically or chemically separated. It is manufactured using a method that removes a part of the outer surface and a method that mixes a scattering material in the core part, but the optical fiber is designed to leak light from the outer surface. If so, those manufactured by other methods are also included.

  According to this fabric, the woven optical fiber is disposed in the storage groove, and movement in the direction parallel to the weft is restricted, that is, positional displacement in the same direction is prevented. Therefore, unlike conventional fabrics in which wefts are simply straddled over an optical fiber, the optical fiber is displaced so that the appearance deteriorates or the fabric itself is damaged. It is possible to prevent this, and the visual effect by light emission can be sufficiently exhibited.

  In the woven fabric, a part of the outer surface of the optical fiber is exposed. As a result, when light is incident from one end face of the optical fiber, much of the light leaking from the outer surface is blocked by the wefts, so that the problem that a sufficient visual effect is not exhibited does not occur.

  Note that if the amount of weft straddling the optical fiber is too small in order to enhance the visual effect of light emission, there is a possibility that the optical fiber will fall out of the storage groove. Therefore, it is preferable that the weft is straddled over the optical fiber so that the visual effect by light emission is sufficiently exhibited, and the optical fiber is prevented from falling off.

  Specifically, it is preferable that the coverage of the outer surface of the optical fiber be 20% to 50%. The coverage of the outer surface of the optical fiber is the ratio of the area of the portion where the weft is straddled to the area of the entire outer surface of the optical fiber when the weft is not straddled.

  Furthermore, according to the above-mentioned fabric, the entire optical fiber can be made to emit light only by entering light from one end face of the optical fiber, so that a wide light emitting area can be secured with a single light source.

  In the woven fabric, it is preferable that the color of at least a portion of the inner wall of the storage groove located below the optical fiber disposed in the storage groove is different from the color of the other portion of the base. .

  In this way, since the color of the portion located below is visually recognized through the optical fiber, even if the outer surface of the optical fiber is not emitting light, the portion where the optical fiber is disposed is regarded as another portion. It can be emphasized by comparison. Further, when the outer surface of the optical fiber emits light, the color of the light visually recognized by the observer becomes a color reflecting the color of the portion located below, so that the same portion is further emphasized, and as a result, both portions Will exhibit a much better visual effect than if they are the same color.

  Further, in the woven fabric, the base is formed along a direction parallel to the warp with a space between each other such that at least two rows of ridges protrude to the surface side of the base. A space between the one ridge and the adjacent ridge can be used as the storage groove. In such a woven fabric, the ridges can be woven with a twill-woven bag weave.

  Even if it does in this way, since it can be in the state which has arrange | positioned the optical fiber between two adjacent protruding item | line parts (accommodation groove | channel), the movement of an optical fiber is restrict | limited and the position shift of the said optical fiber is prevented. be able to.

  In addition, it is preferable that the shape of the woven fabric is a tape shape in consideration of convenience at the time of sewing to clothing or the like.

And the fabric is
The textile,
A module with a light source;
A connector connecting the fabric and the module;
The fabric is connected to the module via the connector so that one end face of the optical fiber faces the light source,
The fabric and the module are preferably used in a light emitting device configured to be connected and separated through the connector.

  According to this light emitting device, since the fabric and the module are connected so that the one end face of the optical fiber faces the light source, the light emitted from the light source enters from the one end face of the optical fiber, and the incident light Leaks from the outer surface and the entire optical fiber emits light, thereby providing a visual effect of light emission.

  Moreover, since the said light-emitting device is comprised so that a textile fabric and a module can be connected / separated via a connector, washing | cleaning of clothing accessories can be performed safely and easily by removing a module from clothing accessories. .

  The light emitting device includes a plurality of the fabrics, the module includes a plurality of light sources, and each of the fabrics has the connector such that each optical fiber faces one of the plurality of light sources. The fabric may be connected to the module via the connector, and the fabric and the module may be configured to be freely connected and separated via the connector. In this case, since one light-emitting device includes an optical fiber that is irradiated with light from a plurality of different light sources, for example, by changing the color of the light that is applied to each optical fiber, it has a very good aesthetic appearance. It is possible to have a large number of variations by changing the combination of the colors of light applied to each fiber.

  The present invention also relates to a clothing apparel including the light emitting device.

  In this apparel and clothing, since the fabric in which the positional deviation of the optical fiber is prevented is used, even if an external force is applied due to the movement of the wearer or contact with a person or an object, it is caused by the positional deviation of the optical fiber. The appearance is prevented from being deteriorated, and the fabric itself is prevented from being damaged, so that the visual effect by light emission can be sufficiently exhibited.

  In addition, as a method of providing a light-emitting device in a clothing apparel, for example, a method of using the fabric as a material of the clothing apparel or a method of sewing a fabric on an existing apparel apparel, The light-emitting device may be attached to the clothing / garments by other methods.

  In addition, the clothing apparel in the present invention is a concept including a hat, a bag, shoes, a wristband and the like in addition to a shirt and pants.

  As described above, according to the woven fabric according to the present invention, it is possible to prevent the positional deviation of the optical fiber in the direction parallel to the weft, and to prevent the occurrence of problems due to the positional deviation of the optical fiber. And can exhibit a very good visual effect. Further, in the light emitting device provided with this fabric and the clothing and apparel including this light emitting device, as described above, the optical fiber is prevented from being displaced in the direction parallel to the weft, and the appearance is deteriorated or the fabric is damaged. Etc., and an excellent visual effect is exhibited.

  Hereinafter, specific embodiments of the present invention will be described with reference to the drawings.

[fabric]
1 and 2 are diagrams schematically showing a schematic configuration of a fabric 1 according to an embodiment of the present invention, and FIG. 3 is a diagram showing a woven structure of the fabric 1. As shown in FIG. 1 and 2 show a part of the fabric 1, the fabric 1 is a tape-shaped, that is, a narrow and long fabric.

  The fabric 1 is composed of a base 2 having a storage groove 4 and an outer surface-emitting optical fiber 5 fixed in the storage groove 4. The base 2 protrudes from the surface of the base 2. As described above, the two ridges 3 and 3 are juxtaposed along the longitudinal direction (direction parallel to the warp) of the woven fabric 1 so that the space between the ridges 3 and 3 functions as the storage groove 4. It has become. In the following description, a portion between the two ridges 3 and 3 in the base portion 2 is referred to as a first base portion 2a, and the other portion excluding the first base portion 2a is referred to as a second base portion 2b. The first base portion 2 a corresponds to a portion located below the optical fiber 5, that is, a bottom portion of the storage groove 4. Also,

  In this woven fabric 1, yarns of the same color are used for the weft 7 and the warp 8a constituting the first base 2a, and the weft 7 is used for the warp 8b constituting the second base 2b and the two ridges 3 and 3, respectively. As shown in FIG. 3, the first base 2a has a twill weave and the second base 2b has a grosgrain, and two ridges 3 as shown in FIG. , 3 is a twill weave bag. In FIG. 3, only a part of the first base 2a located below the optical fiber 5 is shown.

  The first base 2a is woven by twill using the weft 7 and the warp 8a of the same color so that only the colors used for the weft 7 and the warp 8a appear on the front and back surfaces of the first base 2a. It has become.

  The second base 2b is woven by a weave using different wefts 7 and warps 8b. The front and back surfaces of the second base 2b are used for the warp 8b due to the characteristics of the weave. Only the selected color appears.

  Further, the two ridges 3, 3 are woven by twilled bag weaving so that a part thereof protrudes from the surface of the base 2. In addition, wefts 7 and warps 8b having different colors are used for the ridges 3 and 3, and the color used for the warp 8b mainly appears on the front and back surfaces of the ridges 3 and 3. ing.

  Therefore, in this woven fabric 1, the color that appears on the front and back surfaces of the first base 2a is different from the color that appears on the front and back surfaces of the second base 2b and the two ridges 3 and 3. The color of the first base 2a passes through the optical fiber 5 and is observed by an observer.

  As described above, the optical fiber 5 is disposed in the storage groove 4 and is woven as warp with the weft 7 straddling at a predetermined interval in the longitudinal direction. It is fixed in 4 so that the dropout is prevented. If there are too many wefts 7 straddling the optical fiber 5, light emitted from the outer surface of the optical fiber 5 is blocked by the wefts 7, and a sufficient visual effect cannot be obtained. On the other hand, if it is too small, the optical fiber 5 is likely to fall off. Become. Therefore, it is possible to prevent the optical fiber 5 from falling off while making the weft 7 straddle over the optical fiber 5 so that the coverage of the outer surface of the optical fiber 5 is about 20% to 50%, while providing a sufficient visual effect. It is preferable to do so.

  In this example, examples of the weft yarn 7 and the warp yarns 8a and 8b include filament yarns such as polyester yarns, nylon yarns and rayon yarns, as well as spun yarns of synthetic fibers and natural fibers.

  Further, the fabric 1 of this example can be woven using a needle loom, a needle jacquard loom, a shuttle loom, or the like.

  In this fabric 1, the optical fiber 5 is disposed between the storage portion 4, in other words, between the two rows of ridges 3 and 3, and is in a fixed state. The movement in the direction is restricted so that the positional displacement in the same direction does not occur, thereby preventing the deterioration of the appearance and the breakage of the fabric itself.

Next, the structure of the light-emitting device 10 provided with the said textile fabric 1 is demonstrated with reference to FIGS.

  As shown in FIG. 4, the light emitting device 10 of this example includes a module 11, a connector 16 to which the module 11 is detachably connected, and three sheets of fabric 1 attached to the connector 16.

  As shown in FIG. 5, the module 11 includes a housing 12, a rechargeable battery (not shown) built in the housing 12, and three adjacent three of the four side surfaces of the housing 12. The LED light 13 is attached to one side surface and emits light toward the outside. The LED light 13 is supplied with electric power from the battery. The remaining one of the four side surfaces of the housing 12 is provided with a socket 14 to which a micro USB (Universal Serial Bus) plug is connected. The micro USB plug is inserted into the socket 14. The battery can be charged by using so-called USB power feeding. Further, an ON / OFF switch 15 for LED light is provided on the upper surface of the module 11.

  All of the LED lights 13 may irradiate light of the same color, but when at least one irradiates light of a color different from the others, various variations are possible. Can be given.

  The connector 16 is formed by bonding two U-shaped plate members 17, 17 in a top view, and a space 18 for receiving the module 11 is formed at the center portion. A notch 19 that communicates with the outside is formed.

  The three fabrics 1 are respectively attached to three side surfaces of the connector 16 in a state in which each one end portion is sandwiched between the two plate members 17 and 17, and the module 11 is connected to the connector 11. In the state connected to 16, each LED light 13 of the module 11 and the optical fiber 5 of each fabric 1 are opposed to each other.

  According to the light emitting device 1 configured as described above, the light emitted from the LED light 13 enters from one end surface of the optical fiber 5, and the incident light leaks from the outer surface of the optical fiber 5, so that the entire optical fiber 5 Emits light.

[Clothing accessories with light-emitting devices]
Next, although the clothing and apparel provided with the light emitting device 10 will be described, an example in which the light emitting device 10 is provided on the vest 20 will be described below.

You can also have it.

  Further, as described above, the optical fiber 5 of the fabric 1 is fixed in the storage groove 4 and is prevented from being displaced. Therefore, the vest 20 is worn and exercised vigorously. Even if an external force caused by movement or contact with a person or an object is applied, the positional deviation is very difficult to occur, and the occurrence of a problem due to the positional deviation can be prevented and the visual effect by light emission can be continuously exhibited.

  Furthermore, in the fabric 1, since the color appearing on the surface of the first base 2a and the color appearing on the second base 2b and the ridges 3 and 3 are different from each other, even if the optical fiber 5 is not emitting light, the optical fiber The portion where the optical fiber 5 is positioned can be emphasized more than the other portions, and when the entire optical fiber 5 is caused to emit light, the portion where the optical fiber 5 is positioned is more emphasized and an excellent visual effect is exhibited. .

  Furthermore, since the entire optical fiber 5 emits light, in other words, the light emitting area is in a line shape, for example, the light emitting area is wider and visibility is higher than that provided with a single light source. In addition, it is excellent in that the power consumption and the number of parts can be reduced as compared with the case where a plurality of light sources are provided to widen the light emitting region.

  As mentioned above, although embodiment of this invention was described, the aspect which this invention can take is not limited to these at all.

  For example, the woven fabric 1 in the above example forms two rows of ridges 3 and 3 and the space between the two rows of ridges 3 and 3 is a storage groove 4. For example, as shown in FIG. You may make it form accommodation groove | channel 4 'so that it may open in the base 1' surface. In such a woven fabric, for example, the bottom portion of the storage groove 4, that is, the woven structure of the portion 2 a ′ corresponding to the first base portion 2 a in the woven fabric 1 is a twill-woven woven structure, and the portion corresponding to the second base portion 2 b in the woven fabric 1. It is obtained by weaving the 2b 'woven structure as a twilled woven bag to give the same part a thickness.

  Moreover, in the fabric 1 of the above example, the color appearing on the surface of the first base portion 2a and the color appearing on the surfaces of the second base portion 2b and the ridges 3 and 3 are different from each other. It is not limited, and the same color may appear on the surfaces of the first base 2a, the second base 2b, and the ridges 3 and 3.

  In the above example, the weave structure of the first base 2a is a twill weave, the weave structure of the second base 2b is a weave, and the woven structure of the ridges 3 and 3 is a twill weave. Instead, it may be woven with another woven structure.

  Moreover, in the above example, although the fabric 1 showed the aspect which is tape-shaped, it is not restricted to this.

  Furthermore, in the light emitting device 10 of the above example, the three fabrics 1 and the three LED lights 13 are provided, but the number of the fabrics 1 and the LED lights 13 is not limited to this, and more or It may be less than that. Further, in consideration of power consumption and durability, the LED light is used as the light source. However, the present invention is not limited to this, and another light source such as a laser may be used.

  In the light emitting device 10 of the above example, three fabrics 1 are attached to one connector. For example, connectors are attached to one end of the fabric 1, and these connectors are separately connected to the module. As long as one end surface of the optical fiber 5 and the LED light 13 are opposed to each other, the connection form is not particularly limited.

  Moreover, in the above example, the mode in which the clothing apparel was the best was shown, but as the clothing apparel, in addition to shirts, jackets, pants, hats, bags, shoes, gloves, wristbands, etc. Can do.
