| description | To provide a sound absorbing material which is excellent in sound absorption characteristics with respect to sounds of broad frequencies, and has a high peeling strength, even when having thin thickness and low basis weight.SOLUTION: In a sound absorbing material, a non-woven fabric skin layer including a fiber composed of thermoplastic resin, and a short-fiber non-woven fabric base material layer are integrally interlaced. The non-woven fabric skin layer has an interlaced hole of 0.19 mm2 or less of a hole size.SELECTED DRAWING: None
【課題】厚みを薄く、低目付とした場合であっても、広い周波数の音に対する吸音性に優れ、かつ、高い剥離強力を有する吸音材の提供。【解決手段】熱可塑性樹脂からなる繊維を含む不織布表皮層と、短繊維不織布基材層とが、交絡一体化されている吸音材であって、該不織布表皮層が、孔サイズ０．１９ｍｍ2以下の交絡孔を有することを特徴とする吸音材。【選択図】なし |
