Abstract:
1. A formable laid interior decoration material for use in an automobile, the formable laid interior decoration material comprising: a padding material; a non-air-permeable resin sheet layer provided on the padding material; a shape-retaining felt layer comprising melted fiber, the shape-retaining felt layer being provided on the non-air-permeable resin sheet layer; an apertured resin layer having a plurality of apertures penetrating in a thickness direction, the apertured resin layer being provided on the shape-retaining felt layer; an air-permeable design layer provided on the apertured resin layer; wherein the plurality of apertures are configured to secure paths for introducing sound waves from the air-permeable design layer to the shape-retaining felt layer; wherein the shape-retaining felt layer has a weight per unit area of 100 to 1000 g/m wherein the apertured resin layer has a weight per unit area of 50 to 400 g/m wherein the apertures have diameters of 0.1 to 8.5 mm and an aperture rate of 0.05 to 70%; wherein the non-air-permeable resin sheet layer is formed as a substantially non-air permeable layer by extruding thermoplastic resin in a form of a sheet having a weight per unit area of 50 to 3000 g/m wherein a laminate of the air-permeable design layer, the apertured resin layer, the shape-retaining felt layer including melted fiber, the non-air-permeable resin sheet layer, and the padding material is heat formed in a shape that conforms to a shape at a location where the material is laid in the automobile; and wherein the non-air-permeable resin layer forms a hollow structure together with a panel of the automobile, while being spaced from the panel by the padding material.
