LAMINATED NONWOVEN FABRIC AND SOUND ABSORPTION MATERIAL
To provide a nonwoven fabric having durability for practical use, excellent in sound absorption performance in use as sound absorption material, also having excellent moldability; and a sound absorption material made from the same.SOLUTION: A laminated nonwoven fabric includes a spun-bonded nonwoven fabric layer and a melt-blown nonwoven fabric layer which are laminated. The spun-bonded nonwoven fabric on at least one side has an average single fiber diameter of 6.5 to 11.9 μm, an apparent density of 0.05 to 0.4 g/cm, and a stress per unit basis weight when stretched 5% in longitudinal direction of 0.3 to 1 (N/5 cm)/(g/m). A sound absorption material is made from the laminated nonwoven fabric.SELECTED DRAWING: None
【課題】実用に耐えうる耐久性を備え、吸音材用途として吸音性能に優れ、さらには成形性にも優れた不織布およびこれを用いてなる吸音材を提供する。【解決手段】スパンボンド不織布層とメルトブロー不織布層とが積層されてなる積層不織布であって、少なくとも片面のスパンボンド不織布の平均単繊維径が６．５〜１１．９μｍであり、見掛密度が０．０５〜０．４ｇ／ｃｍ３であり、かつ単位目付あたりの縦方向の５％伸長時応力が０．３〜１（Ｎ／５ｃｍ）／（ｇ／ｍ２）である、積層不織布。さらに前記積層不織布を用いてなる吸音材。【選択図】なし
