Abstract: 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.

Abstract: A skin material for vehicle interior is bonded to a resinous vehicle interior base. The skin material for vehicle interior includes a woven fabric woven by using synthetic resin fibers, side emission type optical fibers, and heat fusible fibers as warps or wefts. The synthetic resin fibers and the side emission type optical fibers adjacent to the synthetic resin fibers are bonded in respective longitudinal directions thereof by the heat fusible fibers. Even when a plurality of the side emission type optical fibers are woven between the adjacent synthetic resin fibers, the adjacent side emission type optical fibers may be bonded to each other in the longitudinal direction by the heat fusible fibers. The heat fusible fibers may be obtained by twisting multifilaments and heat fusion yarns having a melting point lower than that of the multifilaments, and the multifilaments remain as constituent yarns after the bonding.

Abstract: There is provided a skin material for vehicle interior, which is woven from a side emission type optical fiber and a synthetic resin fiber, forms a design surface in a vehicle compartment and functions as an illumination. The skin material for vehicle interior is a skin material 10 for vehicle interior including a woven fabric woven by using a synthetic resin fiber and a side emission type optical fiber as warp or weft, wherein the ratio (dS/df) of the fineness (dS) of the synthetic resin fiber to the fineness (df) of the side emission type optical fiber ranges from 1.5 to 7.0. When the synthetic resin fiber is a multifilament 11, the ratio (dS1/df) of the fineness (dS1) thereof to the fineness (df) of the side emission type optical fiber 3 ranges from 2.0 to 7.0. Also, when the synthetic resin fiber is a monofilament, the ratio (dS2/df) of the fineness (dS2) thereof to the fineness (df) of the side emission type optical fiber ranges from 1.5 to 6.0.

Abstract: 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.
