  • Publication number: 20200316906
    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.

  • Publication number: 20200040495
    Abstract: The present disclosure provides: a biodegradable nonwoven fabric for thermoforming, the biodegradable nonwoven fabric being composed of a fiber of a polylactic acid-based polymer, and having a basis weight of 20-300 g/m2, preferably, a biodegradable nonwoven fabric characterized by being composed of a long fiber of a polylactic acid polymer, having an MD-direction elongation of 50% or more at 120° C., and having an MD-direction dimensional change rate of ±4% or less at 80-140° C. as determined by thermomechanical analysis; a method for producing a molded body by using said biodegradable nonwoven fabric; and a method for molding a biodegradable beverage extraction container, the method being characterized in that the molded body has an MD-direction elongation change rate of 4% or less, as determined by thermomechanical analysis (TMA) under a load of 0.05 N/2 mm at 30-100° C.

  • Publication number: 20170002488
    Abstract: Provided is a noise-absorbing sheet that is highly effective at absorbing noise from magnetic and/or electric fields, the noise-absorbing effect being effective in wider bandwidths. A noise-absorbing sheet upon which at least two layers are stacked, wherein the noise absorbing sheet is characterized in that a magnetic layer containing a magnetic material and a layer of a noise-absorbing fabric in which a metal is deposited on constituent fibers are layered on said sheet, and the common logarithmic value of the surface resistivity of at least one side of the noise-absorbing fabric is 0 to 6.
