SOUND ABSORBING NONWOVEN FABRIC AND SOUND ABSORBING MATERIAL INCLUDING THE SAME
PROBLEM TO BE SOLVED: To provide a sound absorbing non-woven fabric capable of improving sound absorption performance of a porous-type sound absorbing material, by being laminated with the porous-type sound absorbing material to be used.SOLUTION: A sound absorbing non-woven fabric according to the present invention is used by being laminated with a porous-type sound absorbing material. The sound absorbing non-woven fabric has a plurality of long-fiber filaments that are extended and arrayed in one direction. The plurality of long-fiber filaments have fiber diameter distributions in which most frequent values are 1-4 μm.SELECTED DRAWING: Figure 1
【課題】多孔質型吸音材と積層して使用されることによって前記多孔質型吸音材の吸音性能を向上させることのできる吸音材用不織布を提供する。【解決手段】本発明による吸音材用不織布は、多孔質型吸音材と積層して使用される。前記吸音材用不織布は、延伸され且つ一方向に沿って配列された複数の長繊維フィラメントを有し、前記複数の長繊維フィラメントの繊維径分布の最頻値が１〜４μｍにある。【選択図】図１
