A skin material for vehicle interior includes a woven fabric woven by using a side emission type optical fiber and a multifilament as warp or weft, and is joined to a substrate for vehicle interior to constitute a vehicle interior material. In a surface of the woven fabric which constitutes the inside of a vehicle compartment, a virtual surface constituted by connecting side surfaces, on the inside of the vehicle compartment, of the side emission type optical fibers is in close vicinity to the substrate for vehicle interior, as compared with a virtual surface constituted by connecting side surfaces, on the inside of the vehicle compartment, of the multifilaments. Examples of the vehicle interior material in which the skin material for vehicle interior is used include door trims and roof trims.

Skin material for vehicle interior

A woven fabric which enables protection of optical fiber yarns while the woven fabric is processed into a design woven fabric and easy exposure of the optical fiber yarns when the protection thereof becomes unnecessary, a method for manufacturing a design woven fabric from this woven fabric, and a method for manufacturing an interior material including: A woven fabric having a first constituent yarn having an optical fiber yarn and a non-light guiding yarn and a second constituent yarn having a non-light guiding yarn. The woven fabric having a first region in which the first and second constituent yarns are woven in one layer and a second region which is positioned adjacent to the first region and in which the first and second constituent yarns and are woven in two or more separable layers. The woven fabric has an optical fiber layer and a back protecting layer as the separable layers. The optical fiber layer is a layer formed of the optical fiber yarns. The back protecting layer is a layer in which the non-light guiding yarn of the first constituent yarn and the non-light guiding yarn of the second constituent yarn are woven. Further, the woven fabric can further have a front protecting layer.

An illumination apparatus includes a woven fabric in which optical fibers are woven as a constituent yarn and a light source. The illumination apparatus makes light delivered from the light source incident upon the end surfaces on one end side of the optical fibers and emits the light at least from the end surfaces on the other end side of the optical fibers for illumination. The other end side of the optical fibers is exposed from the woven fabric to constitute exposed parts, and the end parts of a plurality of the exposed parts on the other end side are supported by an end part support to form emitting parts which emit light from the light source. On the end part support, the end parts of the exposed parts on the other end side are individually supported such that their respective end surfaces are aligned on the same plane.
