Interior material for vehicle including a foamed sheet layer having a foam surface opposing a first rear surface of the first sheet layer, a first sheet layer joined along the foam surface, and a second sheet layer joined to a part of a first surface of the first sheet layer, bonded together while a surface boundary of the first sheet layer and the second sheet layer is kept linear, in which a first surface of the first sheet layer has a joined portion having a width dimension substantially the same as that of the second sheet layer and formed linearly, and a surface treated layer formed excluding the joined portion, and the second sheet layer joined along the joined portion and bonded together by a pressing force with a second surface of the second sheet layer and a foam rear surface of the foamed sheet layer as pressure receiving surfaces.

Vehicle interior materials and their manufacturing methods therefor

A synthetic resin leather has a substrate and a synthetic resin layer attached to the substrate. The substrate is a both sides cross-knitted fabric and is prepared by cross-knitting a first yarn with 10 to 40 in count including single spun or mixed spun fibers made of rayon, cotton, polyester, nylon, acryl, or urethane and a second yarn with 50 to 300 in denier including crimpy long fiber filaments, thermoplastic elastomer long fiber filaments or polyurethane long fiber filaments; and knitting the both-sided cross-knitted fabric so loops made of the first yarn and loops made of the second yarn are formed on the front and rear sides of the substrate and are in alternating positions on the front side as compared to the rear side; and, on each side of the substrate, loops of the first and second yarns are formed in alternating positions in longitudinal and transverse directions.
