  • Nonwoven Fabric and Composite Sound-Absorbing Material Using Same as Skin Material
    Publication number: 20230150230
    Abstract: Provided is a nonwoven fabric and a laminated nonwoven fabric suitable as the skin material of a composite sound-absorbing material. The nonwoven fabric and laminated nonwoven fabric are easily formable, thin, and lightweight and excel in form stability, and can nevertheless be controlled within a given range of aeration after being formed into shape. A nonwoven fabric having a laminate structure in which at least one ultra-fine fiber layer (M) having an average fiber diameter of 0.3 to 7 ?m (inclusive) and a basis weight of 1 g/m2 to 40 g/m2 (inclusive) and at least one continuous filament layer (S) having an average fiber diameter of 10 to 30 ?m (inclusive) are integrated together by partial thermocompression bonding.
