Detailed Description

The present invention will be described with reference to the following embodiments. The present invention is an example, and the present invention is not limited to the following embodiments.

(embodiment mode 1)

< Fabric 100>

Fabric 100 repeats fiber region 52 and decorative region 51. The optical fiber region 52 is a region in which the 7 th fiber 17 as an optical fiber is woven. The decoration region 51 is a region without optical fibers.

The optical fiber region 52 includes a fixed region 52b and a light emitting region 52 a. These two regions are repeated. The fixing region 52b is a region in which the 7 th fiber 17 as an optical fiber is not exposed on the surface but can be hidden and fixed in a state in which the 7 th fiber 17 as an optical fiber is excellent in light guiding property by reducing bending and pressing of the 7 th fiber 17 as an optical fiber.

The fixing region 52b is a region for fixing the 7 th fiber 17.

The light emitting region 52a is a region where light from the optical fiber is released in front.

The decoration region 51 includes a 1 st decoration region 51a and a 2 nd decoration region 51 b. These two regions are repeated.

The 1 st decorative region 51a is a region adjacent to the light emitting region 52 a.

The 2 nd decorative region 51b is a region adjacent to the fixing region 52 b.

The fabric 100 is formed by weaving the 1 st to 7 th fibers 11 to 17.

< decorative region 51b of No. 2>

The skin layer 21 of the 2 nd decorative region 51b is as follows.

The 1

st

11 and 2 nd 12 fibers are located in the Y direction and the 6 th 16 fiber is parallel to the Z direction. The 6 th fiber 16 is woven with the 1 st fiber 11 and the 2 nd fiber 12.

The back layer 23 of the 2 nd decorative region 51b is as follows.

Likewise, the 3 rd fibers 13 and the 4 th fibers 14 are located in the Y direction, and the 5 th fibers 15 are parallel to the Z direction. The 5 th fiber 15 is woven with the 3 rd fiber 13 and the 4 th fiber 14.

In addition, the 7 th fiber 17 as an optical fiber is not present in the middle layer 22.

< fixing region 52b >

The surface layer 21 of the fixing area 52b is as follows.

The 3 rd and 4

th fibers

13 and 14 are located in the Y direction and the 5 th fiber 15 is parallel to the Z direction. The 5 th fiber 15 is woven with the 3 rd fiber 13 and the 4 th fiber 14.

The back layer 23 of the fixed region 52b is as follows.

The 1

st

Further, in the middle layer 22 of the fixing region 52b, the 7 th fibers 17 are positioned in parallel in the Z direction.

The 7 th fiber 17 is an optical fiber. Other fibers are fibers other than optical fibers. The optical fiber is sandwiched and fixed in the space between the surface layer 21 and the back layer 23. In this space, the optical fiber is not woven with respect to other fibers, and the optical fiber is fixed so as not to hinder the linearity. The optical fiber guides light effectively and can emit light.

In addition, the optical fiber is held in the depressed portion between the 35 th fibers 15 and the 36 th fibers 16. In fig. 1 (b) and (c), 2 optical fibers are used, but 3 or more optical fibers may be used.

< light emitting region 52a >

Since the 3 rd and 4

th fibers

13 and 14 are not present in the light emitting region 52a, the light from the optical fiber of the 7 th fiber 17 is easily radiated to the outside. The light emitting region 52a can be provided as necessary.

In addition, the number (ratio) of the fibers may be reduced instead of the 3 rd and 4

th fibers

13 and 14. Light is easily emitted from the optical fiber.

In the light-emitting region 52a in fig. 1 (c), either the 3 rd fiber 13 or the 4 th fiber 14 may remain.

It is preferable that the fiber density of the surface layer of at least the light-emitting region 52a is lower than that of the peripheral region.

Similarly, the 3 rd fibers 13 and the 4 th fibers 14 are not present in the 1 st decorative region 51a on the right and left of the light emitting region 52 a.

The fiber diameters of the 3 rd and 4

th fibers

13 and 14 may be smaller than those of the 1 st and 2

nd fibers

11 and 12.

< decorative region 51a of item 1>

The skin layer 21 of the 1 st decorative region 51a is the same as the skin layer 21 of the 2 nd decorative region 52 a.

The back layer 23 of the 1 st decorative region 51a is as follows.

There are no 3 rd fibers 13 and 4 th fibers 14 in the Y direction and the 5 th fibers 15 are parallel to the Z direction.

In the middle layer 22, the 7 th fiber 17 as an optical fiber is not present.

< 7 th fiber 17>

The 7 th fiber 17 is an optical fiber. From the viewpoint of weaving properties, the optical fiber is preferably made of resin. Specifically, there can be used (1) an optical fiber obtained by combining a core and a cladding having refractive indices associated with no total reflection, or (2) an optical fiber obtained by mixing a light scattering material in a core material.

That is, the optical fiber of the above (1) is of a side emission type in which light not guided in the core is not totally reflected between the core and the cladding, and a phenomenon of light leakage is utilized. On the other hand, the optical fiber of the above (2) is of a side emission type in which light is not totally reflected at the interface between the core and the cladding by mixing of the scattering material, and the scattered light leaks from the side surface of the optical fiber.

In the optical fiber as described above, the side emission luminance can be controlled by adjusting the concentration of the light scattering material in cooperation with the core material. Further, a side-emitting optical fiber having another structure may be used. These side-emitting optical fibers may be used alone or in combination of two or more.

The diameter of the optical fiber is not particularly limited, and can be set to, for example, 0.01mm or more and 2.0mm or less, preferably 0.05mm or more and 1.5mm or less, and more preferably 0.1mm or more and 1.0mm or less, from the viewpoint of appropriately obtaining the weavability.

The 7 th fiber 17 is not necessarily an optical fiber in all, and the proportion thereof is not limited, but is usually 10% or more, preferably 10% or more and 90% or less, more preferably 20% or more and 80% or less, and further preferably 30% or more and 70% or less.

The optical fiber of the following embodiment is also the same as described above.

< fibers 11 to 6>

The 1 st to 6 th fibers 11 to 16 are non-light-conductive yarns. The yarn does not have light guiding properties like an optical fiber. The material constituting the 1 st to 6 th fibers 11 to 16 is not limited, and may be natural fibers or synthetic fibers. In the case of synthetic fibers, examples of the constituent resins include polyamide resins such as nylon 6 and nylon 66, polyester resins such as polyethylene terephthalate, polybutylene terephthalate, and polytrimethylene terephthalate, polyolefin resins such as polypropylene, and polyacrylic resins. These may be used alone or in combination of two or more.

The fiber diameters (fineness) of the 1 st to 6 th fibers 11 to 16 are not particularly limited, and may be, for example, 10dtex or more and 5000dtex or less, preferably 20dtex or more and 4000dtex or less, and more preferably 30dtex or more and 3000dtex or less.

The 1 st to 6 th fibers 11 to 16 may contain no light transmission blocking component, but may contain a light transmission blocking component. When the 3 rd, 4 th and 5

th fibers

13, 14 and 15 contain a light transmission blocking component, the light shielding property of the optical fiber can be improved.

The light transmission blocking component may be any component that can block light transmission, and for example, light transmission may be blocked by reflection/dispersion, light transmission may be blocked by light absorption, or light transmission may be blocked by other actions. Specific examples thereof include colorants (pigments, dyes, etc.), light absorbers, and extenders (various fillers, etc.). These may be used alone or in combination of two or more. Among them, examples of the pigment include organic pigments such as azo pigments, phthalocyanine pigments, pyreneketone pigments, perylene pigments and anthraquinone pigments, and inorganic pigments such as carbon black, ultramarine blue, indian red, titanium oxide and iron oxide. These may be used alone or in combination of two or more. Further, examples of the dye include anthraquinone-based, pyreneketone-based, perylene-based, azo-based, methine-based, quinoline-based dyes. Among them, more dark dyes are preferable, and black dyes are particularly preferable. These may be used alone or in combination of two or more.

< effects >

The light is emitted through the light emitting region 52a and is held by the fixing region 52b firmly without bending the optical fiber. Is a fabric capable of stably and effectively emitting light.

(embodiment mode 2)

In fig. 2, (a) and (b) are sectional views of the fabric 200 of embodiment 2. Unlike embodiment 1, the 8 th fibers 18 are included. The 8 th fiber 18 is a non-optical fiber like the 1 st to 6 th fibers 11 to 16. The items not described are the same as those in embodiment 1. Fig. 2 (a) and (b) show regions corresponding to fig. 1 (b) and (c), respectively. The items not described are the same as those in embodiment 1.

The 7 th fiber 17 (optical fiber) is sandwiched and fixed between the middle layer 22 in the space between the surface layer 21 and the back layer 23. The 8 th fiber 18 is located in the space of the middle layer 22. The 7 th fibers 17 and the 8 th fibers 18 are not woven with respect to the other fibers, and the 7 th fibers 17 (optical fibers) are fixed without hindering the linearity. The 7 th fiber 17 (optical fiber) is not bent and thus can efficiently emit light. The 8 th fiber 18 also has a function of protecting the 7 th fiber 17 (optical fiber). The pressure of the fibers from the surface layer 21 and the back layer 23 is relaxed. The 8 th fibers 18 are disposed on both sides of the optical fiber as the 7 th fiber 17.

In addition, the 7 th fibers 17 and the 8 th fibers 18 may be partially woven with other fibers. In this case, the 7 th fiber 17 and the 8 th fiber 18 are slightly fixed.

In fig. 2 (b), a 9 th fiber 19, which is not an optical fiber, is also disposed between the optical fibers as the 7 th fibers 17.

< fiber diameter >

The fiber diameter of the 8 th fiber 18 is preferably equal to or larger than the fiber diameter of the 7 th fiber 17 (optical fiber). The 8 th fiber 18 is used to protect the 7 th fiber 17 (optical fiber).

The fiber diameter of the 9 th fiber 19 is preferably equal to or smaller than the fiber diameter of the 7 th fiber 17 (optical fiber). The 9 th fiber 19 is for eliminating play in the position of the 7 th fiber 17 (optical fiber).

< effects >

In addition, the optical fiber can be firmly held by the effect of embodiment 1.

Similarly to embodiment 1, light is emitted through the light emitting region 52a, and the optical fiber is firmly held by the fixing region 52 b. Is a fabric capable of stably emitting light. Further, in embodiment 2, the optical fiber can be protected more firmly.

(embodiment mode 3)

In fig. 3, (a) and (b) show regions corresponding to the anchor region 52b and the 2 nd decorative region 51b in embodiment 1.

In the fixing region 52b, the 5 th fibers 15 and the 3 rd fibers 13 are woven, and the 1 st fibers 11 are not woven. The optical fiber of the 7 th fiber 17 is arranged in the region of the middle layer 22 between the surface layer 21 where the 5 th fibers 15 and the 3 rd fibers 13 are woven and the 1 st fiber 11 (the back layer 23). The regions of the intermediate layer 22 are linearly connected, and the straightness of the optical fiber of the 7 th fiber 17 can be ensured. As a result, the optical fiber of the 7 th fiber 17 can be fixed in a state where the light emission efficiency is good.

In the 2 nd decorative region 51b, the 5 th fibers 15 and the 1 st fibers 11 are woven, and the 3 rd fibers 13 are not woven. The optical fiber of the 7 th fiber 17 is not arranged in the region of the intermediate layer 22 between the surface layer 21 and the 3 rd fiber 13 (back layer 23) where the 5 th fiber 15 and the 1 st fiber 11 are woven.

In fig. 3 (b), there is also an 8 th fiber 18 a. Similarly to fig. 2 (a) and (b), in order to protect the optical fiber of the 7 th fiber 17, the 8 th fiber 18a is disposed adjacent to the optical fiber of the 7 th fiber 17. The relationship between the optical fiber of the 7 th fiber 17 and the 8 th fiber 18a is the same as that of embodiment 2. Further, the 9 th fiber 19 of fig. 2 (b) can be used as it is.

< effects >

As in embodiments 1 and 2, light is emitted through the light emitting region 52a, and the optical fiber is firmly held by the fixing region 52 b. Is a fabric capable of stably emitting light. Further, in embodiment 3, this effect can be produced even if the number of fibers is small.

(embodiment mode 4)

Fig. 4 and 5 are schematic top plan and perspective views of a fabric 400 of embodiment 4. Unlike embodiments 1 to 3, the 7 th fiber 17b (optical fiber) is woven, and the 8 th and 9

th fibers

18b and 19b near the 7 th fiber 17b (optical fiber) are woven. Further, there is a region where the 7 th fiber 17b (optical fiber) is not present. The items not described are the same as those in embodiments 1 to 3.

< Overall region >

In the vertical direction of fig. 4, there are an optical fiber region 52 having an optical fiber (7 th fiber 17b) and a decorative region 51 which is a region for decoration without an optical fiber (7 th fiber 17 b).

The optical fiber region 52 is a region where light is emitted through the optical fiber (7 th fiber 17 b). In this region, the 7 th fibers 17b (optical fibers), the 6 th fibers 16b, the 8 th fibers 18b, and the 9 th fibers 19b are woven with the 1 st fibers 11b1 and the 1 st fibers 11b 2.

Further, the light emitting region 52a, the 1 st decorative region 51a, and the 2 nd decorative region 51b are divided into the fixing region 52 b.

In the light emitting region 52a, the 7 th fiber 17b (optical fiber) appears on many surfaces and is a portion where light emission is performed.

In the fixing region 52b, the 7 th fiber 17b (optical fiber) is not present on many surfaces, and is a region where the optical fiber (7 th fiber 17b) is held. The fixing regions 52b are located at both ends of the light emitting region 52a, and in the case where the 7 th fiber 17b (optical fiber) is excessively exposed on the surface of the light emitting region 52a and becomes unstable, the fixing regions 52b reduce bending and pressing of the optical fiber (the 7 th fiber 17b), maintain light guiding properties, and firmly press and hold the optical fiber.

This makes it possible to realize a complex woven fabric having an area where optical fibers are exposed and an area where optical fibers are hidden on the surface, and to exhibit design properties.

The 1 st decorative region 51a is a region that is contrasted with the light emitting region 52a, does not emit light, but is a prominent region of vivid color.

The 2 nd decorative region 51b is a region that is contrasted with the fixed region 52b, and is a region that does not emit light and is dark colored. Can be given a light and shade.

Fig. 4 is a schematic top view of a fabric 400, showing fibers appearing on the surface.

Fig. 5 is a perspective view of the fixing region 52 b. Similarly to the adjacent light emitting region 52a, the 1 st fibers 11b1 and 11b2 traverse the surface layer 21 and the back layer 23. The 7 th fibers 17b (optical fibers), the 6 th fibers 16b, the 8 th fibers 18b, and the 9 th fibers 19b are positioned in the middle layer 22, and the middle layer 22 is sandwiched by the 1 st fibers 11b1 and the 1 st fibers 11b 2.

The fixed region 52b differs from the light-emitting region 52a in the ratio of the 1 st fibers 11b present in the surface layer 21. In the fixed region 52b, the 1 st fiber 11b is present in the surface layer 21 at a higher ratio than in the light-emitting region 52 a.

In the optical fiber region 52 and the ornamental region 51, the 7 th fiber 17b (optical fiber) is different from the 7 th fiber 17c (not optical fiber).

< type of fiber >

The 7 th fiber 17b is an optical fiber. The other is a fiber other than the optical fiber.

The 6 th to 9 th fibers 16b to 19b, the 7 th fiber 17b (optical fiber), and the 7 th fiber 17c are weft yarns. The 1 st fibers 11b1 and 11b2 are warp yarns.

As can be seen from fig. 5, in the fixed region 52b, the middle layer 22 between the 6 th fibers 16b has the 7 th fibers 17b (optical fibers), the 8 th fibers 18b, and the 9 th fibers 19 b.

< middle layer 22>

In the middle layer 22 of the fixed region 52b, 27 th fibers 17b (optical fibers), 28

th fibers

18b, and 19 th fiber 19b are alternately arranged in the middle layer 22 between the 6 th fibers 16 b. Among them, the 8 th fiber 18b and the 9 th fiber 19b are not essential for protecting the 7 th fiber 17b (optical fiber), but are preferably provided.

The middle layer 22 of the 2 nd decorative region 51b has the same structure, but the 7 th fibers 17b (optical fibers) and the 7 th fibers 17c are changed.

< light emitting region 52a >

The 7 th fiber 17b (optical fiber) as the weft is woven by the 1 st fiber 11b (11b1+11b2) as the warp. The 1 st fiber 11b1 is disposed toward the front side of the 7 th fiber 17b (optical fiber), and the 11 1 st fibers 11b (11b1+11b2) are disposed toward the rear side of the 7 th fiber 17b (optical fiber). This cycle is repeated. In this region, the 7 th fiber 17b (optical fiber) is exposed to more surface. And is not limited to 11. 9 to 15.

Of the 8 th and 9

th fibers

th fibers

18b and 19b, and 5 of the 1 st fibers 11b (11b1+11b2) are arranged toward the back side of the 8 th and 9

th fibers

18b and 19 b. This cycle is repeated. And is not limited to 5. In this region, the number of the 8 th fibers 18b and the 9 th fibers 19b exposed on the surface is preferably smaller than the number of the 7 th fibers 17b (optical fibers) exposed on the surface. So as not to be more prominent than the 7 th fiber 17b (optical fiber).

The 6 th fibers 16b as the weft are woven by the 1 st fibers 11b1, 11b2 as the warp. 11 of the 1 st fibers 11b (11b1+11b2) are arranged toward the rear side of the 6 th fiber 16b, and 1 of the 1 st fibers 11b2 is arranged toward the front side of the 6 th fiber 16 b. This cycle is repeated.

The period of the 27 th fibers 17b (optical fibers), the period of the 28 th fibers 18b, and the period of the 19 th fibers 19b are shifted in phase. The structure is such that the 7 th fiber 17b (optical fiber) is maintained in homogeneity of light emission, that is, in an overall homogeneous state.

< decorative region 51a of item 1>

The structure is the same as that of the light emitting region 52a, but the 7 th fiber 17b (optical fiber) is changed to the 7 th fiber 17 c.

The 7 th fibers 17c as weft are woven by the 1 st fibers 11b1, 11b2 as warp. 4 and 5 of the 1 st fibers 11b1 and 11b2 are arranged toward the front side of the 7

th fiber

17c, and 1 and 11 of the 11 th fibers 11b1 and 11b2 are arranged toward the back side of the 7 th fiber 17 b. This cycle is repeated. The 11 fibers may not be 11 fibers, and 9 to 15 fibers may be used, as in the 7 th fiber 17b (optical fiber) of the light-emitting region 52 a.

In the 8 th fibers 18b as the weft, 1 of the 1 st fibers 11b2 is arranged toward the back side of the 8 th fibers 18b, and 3 of the 1 st fibers 11b1 are arranged toward the front side of the 8 th fibers 18 b. This cycle is repeated.

As shown in fig. 4, with respect to the 9 th fibers 19b positioned between the portions where the 27 th fibers 17c are arranged toward the 11 1 st fibers 11b1, 11b2 on the front side, 1 st fiber 11b2 is arranged on the front side, and 31 st fibers 11b1 are arranged on the back side of the 9 th fiber 19b, and this cycle is repeated. In the other portions, 3 of the 1 st fibers 11b1 were arranged toward the front side of the 9 th fiber 19b, and 1 of the 1 st fibers 11b2 were arranged toward the back side of the 9 th fiber 19b, and this cycle was repeated.

The 6 th fibers 16b as the weft are woven by the 1 st fibers 11b1, 11b2 as the warp. 11 of the 1 st fibers 11b1 and 11b2 are arranged toward the rear side of the 6 th fiber 16b, and 1 of the 1 st fibers 11b2 is arranged toward the front side of the 6 th fiber 16 b. This cycle is repeated.

The period of the 27 th fibers 17c is shifted in phase.

< fixing region 52b >

The 7 th fibers 17b (optical fibers) as weft are woven by the 1 st fibers 11b1, 11b2 as warp. The 31 st fibers 11b1 are disposed toward the front side of the 7 th fiber 17b (optical fiber), and the 1 st fiber 11b2 is disposed toward the rear side of the 7 th fiber 17b (optical fiber). This cycle is repeated.

The same applies to the 8 th and 9

th fibers

18b and 19b as weft yarns. The 3-root and 1-root cycles are examples, and other cycles may be used. Preferably 3 to 5. Particularly preferably 3.

The periods of the 8 th fibers 18b, the 7 th fibers 17b (optical fibers), and the 9 th fibers 19b are the same, and are aligned in a row in the vertical direction in fig. 4. According to this row, the 7 th fiber 17b (optical fiber) is slowly held as a whole.

In the fixing region 52b, the 7 th fiber 17 (optical fiber) is fixed inside without being exposed to the surface. Further, the optical fiber (7 th fiber 17b) can be firmly held without being bent.

< decorative region 51b of No. 2>

The 7 th fibers 17c as weft are woven by the 1 st fibers 11b1, 11b2 as warp. The 7 1 st fibers 11b1 are arranged toward the front side of the 7 th fiber 17c, and the 1 st fibers 11b2 are arranged toward the rear side of the 7 th fiber 17 c. This cycle is repeated.

Of the 8 th fibers 18b as weft yarns, 31 st fibers 11b1 are arranged toward the front side of the 8 th fibers 18b, and 1 st fiber 11b2 is arranged toward the back side of the 8 th fibers 18 b. This cycle is repeated.

The period of the 27 th fibers 17c is shifted in phase.

< full region >

The 6 th fiber 16b has no change in the weave pattern in both the decorative region 51 and the optical fiber region 52.

The 7 th fibers 17b (optical fibers), the 8 th fibers 18b, the 9 th fibers 19b, and the 7 th fibers 17c are woven in different manners in the decorative region 51 and the optical fiber region 52.

< diameter >

The 6 th fiber 16b has a larger diameter than the 7 th, 8 th, and 9 th fibers 17b (optical fibers), 18b, and 19 b. The 6 th fiber 16b ensures the strength of the entire fabric 400.

< 7 th fiber 17b, 8 th fiber 18b, 9 th fiber 19b >

The 7 th fibers 17b (optical fibers) and the 8 th fibers 18b are the same as the 7 th fibers 17, the 8 th fibers 18, and the 9 th fibers 19 in fig. 2 (a) and (b). That is, the 8 th fibers 18b may be absent. As shown in fig. 2 (a), 27 th fibers 17b (optical fibers) may be sandwiched between 28 th fibers 18 b. The configuration shown in fig. 2 (b) is also possible. The diameters of the 7 th fiber 17b (optical fiber) and the 8 th fiber 18b are the same as those of the 7 th fiber 17 and the 8 th fiber 18.

As is clear from fig. 5, the thick 26 th fibers 16b form an overall bone lattice, and can secure strength.

< fiber region 52 and decorative region 51>

In the optical fiber region 52 having the optical fiber (7 th fiber 17b) and the decoration region 51 having no optical fiber but a region for decoration, the distribution of the bright portion is the same. That is, the 1 st decorative region 51a exists opposite to the light emitting region 52 a. The light emitting region 52a is brighter than the optical fiber (7 th fiber 17 b). On the other hand, the 1 st decorative region 51a is brighter than the 7 th fibers 17 c. At night, since the optical fiber (7 th fiber 17b) is lit, the light emitting region 52a draws attention brightly, and during the day, the 1 st decorative region 51a draws attention. In both regions, the optical fiber (7 th fiber 17b) is arranged similarly to the 7 th fiber 17 c.

< effects >

Similarly to embodiment 1, light is emitted through the light emitting region 52a, and the optical fiber (7 th fiber 17b) is firmly held by the fixing region 52 b. Is a fabric capable of stably emitting light.

Further, in embodiment 4, the 7 th fibers 17b (optical fibers) and the 7 th fibers 17c are arranged in contrast in the light emitting region 52a and the 1 st decorative region 51a, and the periodicity of the plurality of 7 th fibers 17b (optical fibers) and the 7 th fibers 17c is different from each other, so that the decorativeness is high.

In the above configuration, the 7 th fiber 17b (optical fiber) can be protected without being exposed on the back surface. Further, since the 7 th fiber 17b (optical fiber) is not bent so much, the light radiation efficiency can be improved without breakage.

(embodiment 5)

Fig. 6 is a schematic top view of a fabric 500 of embodiment 5. Fig. 7 and 8 are perspective plan views of a fabric 500 according to embodiment 5, which are a front surface and a back surface, respectively. The fabric 500 has a light emitting region 52a, a fixing region 52b, and a pocket region 52 c. The items not described are the same as those in the above embodiment.

The fabric 500 has only the optical fiber region 52 as a region having the optical fibers (7 th fibers 17b), but may have the decorative region 51 as in the fabric 400 of embodiment 4.

The light-emitting region 52a is a region that emits light.

The fixing region 52b is a region where the optical fiber (7 th fiber 17b) is fixed and hidden from the surface. The optical fiber (7 th fiber 17b) is a region in the fabric 500 in which the optical fiber is stably fixed without bending and breakage.

The pocket region 52c is a pocket region in which the optical fiber (7 th fiber 17b) is covered with a sheet of the back-layer and surface-layer fibers. Is a region for connecting an optical fiber (7 th fiber 17b) to a light source such as an LED.

< type of fiber >

The 7 th fiber 17b is an optical fiber. In addition, the optical fiber is not an optical fiber.

The 6 th, 8 th, and 7

th fibers

16b, 18b, and 17b (optical fibers) are weft yarns. The 1 st fiber 11b1 and the 1 st fiber 11b2 are warp yarns.

The warp yarn has only the 1 st fiber 11b1 and the 1 st fiber 11b 2.

The weft yarn repeats the 6 th fiber 16b, the 8 th fiber 18b, the 7 th fiber 17b (optical fiber), and the 6 th fiber 16b in this order. Between the 26 th fibers 16b, there are 28 th fibers 18b and 7 th fibers 17b (optical fibers), respectively.

< light emitting region 52a >

The light emitting region 52a is a region where the optical fiber (7 th fiber 17b) is largely exposed on the surface.

In fig. 6, if one square is used as a heddle eyelet, the 7 th fiber 17b (optical fiber) is exposed to 5 or 6 heddle eyelets on the surface and 1 heddle eyelet is exposed to the back side of the 1 st fiber 11b 1.

The number of the heddle eyes of the 7 th fiber 17b (optical fiber) exposed on the surface is preferably 5 to 12.

In fig. 9, (a) shows a side perspective view of the light-emitting region 52a, and (b) shows a schematic cross-sectional view of the light-emitting region 52 a.

Comprises a surface layer 21, a middle layer 22 and an inner layer 23.

The 7 th fiber 17b (optical fiber) is positioned on the surface layer 21 and emits light.

The 6 th fiber 16b is located in the inner layer 23, taking balance. Ensuring the strength of the fabric 500.

The 1 st fibers 11b include the 1 st fibers 11b1 on the surface layer side and the 1 st fibers 11b2 on the inner layer side.

The 8 th fibers 18b are mainly located in the middle layer 22, but are partially located in the surface layer 21 and the inner layer 23, and are bonded to the surface layer 21 and the inner layer 23. Therefore, the two positions of the solid line and the broken line are back and forth.

The fiber diameter is reduced in the order of the 7 th fiber 17b (optical fiber), the 6 th fiber 16b, and the 8 th fiber 18 b.

The 6 th fiber 16b is thick to secure the strength of the fabric 500. The 8 th fibers 18b are thinner than the 6 th fibers 16b, and the layers are connected.

< pocket area 52c >

In fig. 10, (a) shows a side perspective view of the pocket area 52c, and (b) shows a schematic cross-sectional view of the pocket area 52 c.

The optical fiber of the 7 th fiber 17b is not exposed on both the front and back surfaces, and is located in the middle layer 22.

The back layer 23 is composed of the 6 th fibers 16b and the 1 st fibers 11b1, 11b 2.

The surface layer 21 is composed of the 8 th fibers 18b and the 1 st fibers 11b 1.

The optical fiber of the 7 th fiber 17b has a layer on the back surface and the surface thereof to protect the 7 th fiber 17b (optical fiber) during manufacture and operation. Since the optical fiber (7 th fiber 17b) is not woven with other fibers, it is easily connected to a light source such as an LED.

< fixing region 52b >

In fig. 11, (a) shows a side perspective view of the fixing area 52b, and (b) shows a schematic cross-sectional view of the fixing area 52 b.

The 7 th fiber 17b (optical fiber) is located in the middle layer 22. The 6 th fiber 16b is located in the inner layer 23. The 8 th fibers 18b are located in both the middle layer 22 and the surface layer 21, and fasten the surface layer 21 and the inner layer 23. The 1 st fibers 11b include the 1 st fibers 11b1 on the surface layer side and the 1 st fibers 11b2 on the inner layer side.

As is clear from fig. 6, 7, and 8, the 1 st fiber 11b1 is located on the 3 rd heddle eyelet surface side and the 1 st fiber 11b2 is located on the 1 st heddle eyelet back side with respect to the 7 th fiber 17b (optical fiber). This is repeated. If the number of the heddle eyes is less than 3, the optical fiber (7 th fiber 17b) is easily bent, and the light extraction ratio is increased at the portion, so that the light guiding property is deteriorated and the fiber is easily damaged. Therefore, 3 or more heddle eyes are preferable. If the number of the heddle eyes is more than 5, the holding property of the optical fiber (7 th fiber 17b) is lowered. Therefore, 3-to 5-heddle eyes are preferred. Particularly, 3-heddle eyes are preferable. In this 1 heddle eyelet (the 1 st fiber 11b2), the 1 st fiber 11b2 is located in the back layer 23.

Thus, the 8 th fibers 18b appear on the front and back surfaces, and go back and forth between the surface layer 21 and the back layer 23.

The 6 th fibers 16b appear alternately on the front and back surfaces and are located in the inner layer 23.

The 7 th fiber 17b appears at the surface, in the middle layer 22.

The portions (portions where the 6 th fibers 16b and the 7 th fibers 17b appear on the surface) are arranged in a line in the vertical direction of fig. 6. Along this line, the bending and pressing of the optical fiber (7 th fiber 17b) are gradually reduced as a whole, and the light guiding property is maintained and maintained.

As can be seen from fig. 6, the 1 st fiber 11b (11b1+11b2) is located on the 7 th heddle eyelet surface side and on the 1 st heddle eyelet back side with respect to the 6 th fiber 16 b. This is repeated. The 6 th fibers 16b are not present so much on the surface in order to secure the strength of the fabric 500. Instead of 7 eyes, the range of 5 eyes to 9 eyes may be used.

As is clear from fig. 6, 7, and 8, the 1 st fibers 11b1 are positioned on the 4 th heddle eyelet surface and on the 1 st heddle eyelet back surface side in the top sheet 21 with respect to the 8 th fibers 18 b. In addition, in the inner layer 23, the 1 st fibers 11b2 appear on the 1 heddle eye surface and are located on the 3 heddle eye back side, and have periodicity.

< effects >

Similarly to embodiment 1, the light is emitted through the light emitting region 52a, and is held by the fixing region 52b so as to securely hide the 7 th fiber 17b (optical fiber) from the surface. The fabric 500 can stably emit light. That is, the 7 th fiber 17b (optical fiber) is not exposed on the surface (outermost surface) and is not bent so much and held inside, so that the 7 th fiber 17b (optical fiber) can be protected, light guiding performance is good, and light can be uniformly radiated.

Further, in embodiment 5, the optical fiber (7 th fiber 17b) is easily connected to a light source or the like in the pocket region 52 c.

In the light emitting region 52a, the 7 th fiber 17b (optical fiber) is exposed to the surface and emits light. In the fixing region 52b, the 7 th fiber 17b (optical fiber) is fixed inside. The fixing region 52b hardly exposes the optical fiber (the 7 th fiber 17b) on the surface, but exposes only a part of the surface, and fixes and holds the optical fiber without bending it too much.

In the light emitting region 52a, many optical fibers (7 th fibers 17b) appear in the surface layer 21, and light is emitted.

In the fixing region 52b, the optical fiber (7 th fiber 17b) is positioned in the middle layer 22, and the optical fiber (7 th fiber 17b) is fixed.

In the light emitting region 52a and the fixed region 52b, the 8 th fiber 18b connects the surface layer 21 and the back layer 22.

In embodiments 1 to 4, the surface layer 21 and the back layer 23 are alternately arranged and integrated as a whole. In this example, the top layer 21 and the back layer 23 are bonded by the 8 th fibers 18 b. As a result, the fabrics of embodiments 1 to 5 are all integrated as a whole.

< embodiments 1 to 5>

The proportion of the 1 st fiber 11b in the fixing region 52b on the surface side of the 7 th fiber 17b (optical fiber) is larger than the proportion of the 1 st fiber 11b in the light emitting region 52a on the surface side of the 7 th fiber 17b (optical fiber).

The knitting method of the surface layer 21 and the back layer 23 is not limited. Various weaving modes such as satin weaving, rib weaving and the like can be adopted.

The above embodiments 1 to 5 can be combined.

(embodiment mode 6)

Fig. 12 (a) to 13 (b) are views for explaining embodiment 6. The items not described are the same as those in the above embodiment.

Fig. 12 (a) shows the end portions of the woven fabric 91 according to embodiments 1 to 5. Indicating the state where the optical fiber 90 and the LED light source 96 are connected.

Fig. 12 (b) shows an end portion of the fabric 92 according to embodiment 6. The optical fiber 90 is replaced by a tube 93 as a cylindrical body, and the LED light source 96 is replaced by a fragrance source 95. The tube 93 is a belt-like or rod-like tube having a hollow path such as a tube, a wire, a conductive yarn, or a piezoelectric yarn inside.

The source of the fragrance 95 is a source of the fragrance, and is a perfume, a drug, or the like. Both liquid and gas can be used. In the case of a drug, if a bactericidal drug is used, sterilization can be performed in a hospital or the like. Can remove virus and bacteria. If an agent aversive to pests such as mosquitoes and flies is used as a source, the pests can be prevented from approaching the source.

In addition, if the source of the cool wind or the warm wind is concerned as the flavor source 95, the cool wind or the warm wind can be emitted. Here, the source of the cold air and the warm air is a fan, a cold air blower, a combination of a heater and a blower, a combination of ice or dry ice and a blower, or the like.

Further, if the tube 93 is a fiber through which current flows and the flavor source 95 is a battery, the tube 93 can be operated as a heater to warm the air. In addition, the dust in the room can be prevented from approaching by static electricity. It can also replace the battery to connect with the socket and the storage battery.

The items not described are the same as those in the above embodiment.

The fabric 92 carries scent from a scent source 95 through the tube 93, emitting scent from the fabric 92. When used for curtains, wallpaper, etc., the fragrance can be diffused into a room.

Fig. 12 (c) shows a tube 93. The tube 93 of the cylindrical body can transport flavor through the hollow inside. The tube 93 is woven with the 1 st fibers 11 b. Various gases such as fragrance are emitted from the opening 94 to the outside. If the ratio of the opening area provided as the openings 94 becomes larger as it is farther from the fragrance source 95, fragrance is easily emitted from the whole.

Fig. 13 (a) to (b) are views showing examples of application of the woven fabric 92 according to embodiment 6.

Fig. 13 (a) is a view showing a base 102 such as a curtain or a wall into which a fabric 92 is incorporated. Can be used for the interior of automobiles, rooms, toilets, etc. Fig. 13 (b) is a diagram of arranging the fabric 92 in a part of the article 101. The fabric 92 can be disposed in a part of a home appliance, an information device, or the like as the article 101.

Since the fragrance or the like is emitted from the surface, the fragrance or the like can be more effectively transmitted to the user than in the case of emitting the fragrance or the like from a single point in the past.

In the woven fabric according to embodiments 1 to 5, the tube 93 may be used instead of the 7 th fiber 17. Like the optical fiber, the tube 93 can more easily and efficiently emit a gas such as a fragrance when it is not bent.

(embodiment 7) Lighting device with solar cell

Embodiment 7 relates to a lighting device 801. The items not described are the same as those in the above embodiment.

< Structure >

Fig. 14 shows (a) a plan view of the lighting device 801 and (b) an enlarged sectional view of the plane a-a of (a). The lighting device 801 includes a fabric 800, a flexible substrate 97, and a solar cell 30.
