ABSTRACT:
A nonwoven fabric containing a polyvinyl butyral fiber is provided. In particular, continuous fiber nonwoven fabrics, such as a melt-blown nonwoven fabric and a spunbonded nonwoven fabric, are preferred. By laminating a plurality of layers via an adhering layer made of such a nonwoven fabric and then heating, a laminate is obtained by a simple process. In particular, an interior material in which an inorganic fiber layer, a foam layer and a surface material layer are adhered together via the aforementioned type of adhering layers is a desirable embodiment. Such an interior material is excellent in rigidity, sound absorbency and thermal deformation resistance, and therefore is useful as an interior material to be used for cars, railway vehicles, vessels, and the like.
