An interior-finishing material for use in automobiles including a substrate made of a needled glass-fiber sheet containing a thermoplastic resin binder, with the said needled glass-fiber sheet being mainly composed of glass fiber, a heat-fusible adhesive layer with air permeability disposed on the substrate, and a surface layer with air permeability disposed on the adhesive layer, and the substrate further contains expanded microbeads.

Method for producing interior-finishing material for use in automobiles

A laminated structure comprising a laminated foamed sheet material composed of two cured foamed sheets each comprising a propylene-type polymer and an ethylene-type polymer and being laminated to each other through a substantially non-foamed or lowly foamed heat-fused layer, and non-foamed surface skin layers composed of a propylene-type polymer and laminated respectively to both surfaces of said laminated foamed sheet material, the ratio of the thickness Ts of each of said surface skin layer to the solid thickness Tf of each of the cured foamed sheets, Ts/Tf, being from 1 to 50, the thickness T1 of the heat-fused layer being 0.1 to 0.5 mm, and the thickness T1 being 1 to 25% of the thickness of each of the cured foamed sheets. The laminated structure can be produced by extrusion-laminating a non-foamed surface skin layer of a propylene-type polymer to one surface of each of two cured foamed sheets each comprising a propylene-type polymer and an ethylene-type polymer to thereby form two laminates, placing the two laminates such that the surfaces of the cured foamed sheets face each other, and melting and bonding the facing two surfaces to form a substantially non-foamed or lowly foamed heat-fused layer between the laminates.
