  • Patent number: 4830900
    Abstract: An interior material for cars comprising a web in which at least 3% by weight of a rayon fiber is contained, of which one side surface is impregnated with a binder and which has a 20% modulus of 1 to 15 kg/5 cm. width in both longitudinal direction and transverse direction, a base material laminated on the binder-impregnated surface of the web and a resin print laminated on the other side surface of the web. The interior material can be easily subjected to molding such as deep drawing since no space is generated between a base sheet and a non-woven fabric. Further, since the interior material has an excellent flame resistance, it can be suitably used as an interior material such as a ceiling material, a door trim board or a pillar garnish material.
