Abstract

A textile fabric has at least one fabric layer with warp and weft threads and at least one light emission layer abutting onto the first fabric layer in a flat manner and is connected to this and is formed for the conduction and the emission of light. This arrangement provides a textile fabric that provides ambient illumination.

First claim

The invention claimed is:

1. A textile fabric, comprising:
a first fabric layer having warp and weft threads; and
a light emission layer abutting onto the first fabric layer in a flat manner, wherein the light emission layer is connected to the first fabric layer, and wherein the light emission layer is configured to conduct and emit light,
wherein
the light emission layer comprises a second fabric layer having warp and weft threads,
at least one of the warp or weft threads of the second fabric layer is an optical fiber configured to at least partially extract light transversely to a longitudinal direction of the optical fiber,
the optical fiber is undulated in the second fabric layer by weft or warp threads that are complementary to the optical fiber.

2. The textile fabric of claim 1 , wherein the optical fiber comprises a synthetic fiber made from polymethacrylic acid ester, polystyrene, or polycarbonate.

3. A textile fabric, comprising:
a first fabric layer having warp and weft threads; and
a light emission layer abutting onto the first fabric layer in a flat manner, wherein the light emission layer is connected to the first fabric layer, and wherein the light emission layer is configured to conduct and emit light,
wherein the light emission layer comprises an electroluminescent yarn that is arranged to be free of undulations between the first and a third fabric layer.

4. A textile fabric, comprising:
a first fabric layer having warp and weft threads;
a light emission layer abutting onto the first fabric layer in a flat manner, wherein the light emission layer is connected to the first fabric layer, and wherein the light emission layer is configured to conduct and emit light; and
a reflective layer on a surface of the light emission layer facing away from the first fabric layer, wherein the reflective layer is configured to reflect light emitted from the light emission layer in a direction of the first fabric layer,
wherein the reflective layer is a third fabric layer having warp and weft threads.

5. The textile fabric of claim 4 , wherein the third fabric layer comprises at least one synthetic fiber made from polymethacrylic acid ester.

6. The textile fabric of claim 4 , wherein the light emission layer is fixed to the first fabric layer or the reflective layer by a first or second adhesive layer.

7. The textile fabric of claim 4 , wherein
the light emission layer is fixed to the first fabric layer or the reflective layer by at least one connection warp thread or at least one connection weft thread, or
the reflective layer is fixed to the first fabric layer by at least one connection warp thread or at least one connection weft thread.

8. The textile fabric of claim 4 , wherein
the first fabric layer, second fabric layer, or third fabric layer comprises at least one elastane yarn, or
the first fabric layer comprises at least one transparent synthetic fiber made from polypropylene or polyester or polyamide, at least one transparent natural fiber made from silk or cotton, or the first, second, or third fabric layer comprises a heatable or electrically conductive or fluorescent or antibacterial thread.
