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.

Skin material for vehicle interior

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 materialfor 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 (d/d) of the fineness (d) of the synthetic resin fiber to the fineness (d) of the side emission type optical fiber ranges from 1.5 to 7.0. When the synthetic resin fiber is a multifilament, the ratio (d/d) of the fineness (d) thereof to the fineness (d) of the side emission type optical fiberranges from 2.0 to 7.0. Also, when the synthetic resin fiber is a monofilament, the ratio (d/d) of the fineness (d) thereof to the fineness (d) of the side emission type optical fiber ranges from 1.5 to 6.0.

Provided is a skin material which forms a vehicle interior design surface, functions as lighting, and suppresses the fray of side emission type optical fibers. The skin material includes a woven fabric woven by using synthetic resin fibers, side emission type optical fibers, and heat fusible fibers as warps or wefts. A ratio (d/d) of fineness (d) of the synthetic resin fibers to fineness (d) of the side emission type optical fibers is from 1.5 to 7.0. 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. 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 are bonded to each other in the longitudinal direction by the heat fusible fibers.
