Abstract:
A vehicle interior material that is manufactured at by bonding a base member and a surface member with each other without using an adhesive agent or an adhesive film, that is light in weight and that has adhesive strength and abrasion resistance. The base member includes a natural fiber or a glass fiber and a first thermoplastic resin fiber and has a density of 0.2 to 0.7 g/cm3 The surface member includes a second thermoplastic resin fiber and a low melting point resin fiber and that has a weight per unit area of 50 to 500 g/m2. The surface member is laid on a surface of the base member. An entangled layer where the second thermoplastic resin fiber enters texture of the base member to be entangled with the first thermoplastic resin fiber is provided at an interface between the base member and the surface member.
