Abstract

A woven fabric including: a fixing region where an optical fiber of a seventh fiber is held, and a light emitting region where the optical fiber of the seventh fiber is included to emit light. The woven fabric includes: aback layer in which a first fiber, a second fiber, and a sixth fiber are woven; a surface layer in which a third fiber, a fourth fiber, and a fifth fiber are woven; and the optical fiber arranged in a space of an intermediate layer between the surface layer and the back layer.

Claims

1. A woven fabric comprising:

a fixing region where an optical fiber of a seventh fiber is held; and

a light emitting region where the optical fiber is included to emit light,

wherein the woven fabric includes;

a surface layer in which a third fiber, a fourth fiber, and a fifth fiber are woven; and

the optical fiber arranged in a space of an intermediate layer between the surface layer and the back layer.

4. The woven fabric according to claim 1, wherein an eighth fiber is further arranged in the space of the intermediate layer.

5. The woven fabric according to claim 4, wherein a plurality of optical fibers are provided, and

the eighth fiber is arranged at each of end portions of the plurality of optical fibers, and a ninth fiber is arranged between the plurality of optical fibers.

6. The woven fabric according to claim 5, wherein a fiber diameter of the ninth fiber is equal to or smaller than a fiber diameter of the optical fiber.

7. The woven fabric according to claim 1, comprising:

the fixing region where the optical fiber of the seventh fiber is held; and

the light emitting region where the optical fiber is included to emit light,

wherein the fixing region has;

a surface layer in which the first fiber and an eighth fiber are woven;

a back layer in which the first fiber, the sixth fiber, and the eighth fiber are woven; and

the optical fiber arranged in a space of an intermediate layer between the surface layer and the back layer.

8. The woven fabric according to claim 1, comprising:
