A vehicle interior and exterior trim (10) is provided with a base material layer (11) and a sound-absorbing layer (15). The base material layer (11) is a fiber molded body containing a thermoplastic synthetic resin (12). The sound-absorbing layer (15) is formed by laminating a fiber web (16) formed by interweaving thermoplastic synthetic fibers (18) and a cover layer (17), and the cover layer (17) is a non-woven fabric containing thermoplastic synthetic fibers (18). The fiber web (16) of the sound-absorbing layer (15) is laminated on one surface of the base material layer (11). The sound-absorbing layer (15) has an adhesive section (21), a sound-absorbing section (22), and a crimped section (23). The adhesive section (21) is cured in a state in which the thermoplastic synthetic fibers (18) on the surface in contact with the base material layer (11) and the thermoplastic synthetic resin (12) of the base material layer (11) are thermally adhered to each other. The thermoplastic synthetic fibers (18) of the sound-absorbing part (22) are not melted and maintain a fiber web state. The crimped portion (23) is formed by thermocompression bonding of the base material layer (11), the fiber web (16) and the cover layer (17) in a state in which the base material layer (11), the fiber web (16) and the cover layer (17) are compressed in the thickness direction.

    交通工具用内外饰(10)具有基材层(11)和吸音层(15)。基材层(11)是含有热塑性合成树脂(12)的纤维成型体。吸音层(15)是含有热塑性合成纤维(18)并交织而成的纤维网(16)与覆盖层(17)层叠而成,覆盖层(17)为含有热塑性合成纤维(18)的无纺布。吸音层(15)的纤维网(16)层叠在基材层(11)的一个面上。吸音层(15)具有粘接部(21)、吸音部(22)及压接部(23)。粘接部(21)在与基材层(11)接触的面的热塑性合成纤维(18)和基材层(11)的热塑性合成树脂(12)热粘接的状态下被固化。吸音部(22)的热塑性合成纤维(18)不熔融而维持纤维网状态。压接部(23)是基材层(11)与纤维网(16)、覆盖层(17)在厚度方向上被压缩的状态下热压接而成。
