摘要:
A fibrous shaped article having a surface with raised and depressed portions, said fibrous article consisting of a unitary laminated structure resulting from the compression molding under heat of (A) a heat compression-moldable nonwoven fibrous web and (B) a nonwoven fibrous sheet, said fibrous sheet (B) being laminated to at least one surface of said fibrous web (A); said fibrous web (A) having a compression stress, at 10% compression at the temperature of said compression molding, of at least 0.5 g/cm.sup.2 ; said nonwoven fibrous sheet (B) consisting of a continuous unitary reticulated sheet structure of an assembly of many fibers of a thermoplastic polymer, said constituent fibers having an initial modulus of not more than 5 g/denier and an elongation of at least 20% both at the temperature of said compression molding and being interconnected in a spaced-apart relationship, and said nonwoven fibrous sheet (B) having a plastic deformation ratio, at 30% elongation at the temperature of said compression molding, of at least 50% and an elongation stress, at 30% elongation at the temperature of said compression molding, of not more than 0.15 kg/cm; and said web (A) and said sheet (B) satisfying the following relation:S.ltoreq.0.03 Tin which T is the compression stress (g/cm.sup.2) of said web (A) at 10% compression at the temperature of said compression molding, and S is the elongation stress (kg/cm) of said sheet (B) at 30% elongation at the temperature of said compression molding. This article is useful as soundproofing materials, heat insulating materials, cushioning materials, etc.
