SOUND ABSORBING SKIN MATERIAL AND SOUND ABSORBING MATERIAL UTILIZING THE SAME
흡음성, 성형성이 우수한 경량의 흡음성 표피재, 및 그것을 사용한 흡음재를 제공한다. 섬유 시트(3)의 한 면 또는 양면에 크레이프 가공 및/또는 엠보싱 가공 된 연신성 종이재(예컨대, 크레이프 가공지(1b))를 적층하여 흡음성 표피재(6)로 했다. 상기 연신성 종이재는 크레이프율을 10~50%, 돌기 높이를 0.02~2.00㎜, 돌기수를 20~200개/c㎡로 했다. 또한, 흡음성 표피재(6)에 시트상의 통기성 다공질 재료(7)를 적층해서 흡음재(8)로 했다.
A lightweight sound absorbing surface material, having an excellent sound absorbing property and moldability, and a sound absorbing material using the sound absorbing surface material, are provided in the present invention. The sound absorbing surface material 6 is manufactured by laminating stretchable paper(s) which is (are) creped and/or embossed (such as a creped paper 1b) onto one or both sides of a fiber sheet 3. The degree of creping of the paper is in the range of between 10 and 50 %, and the height of projections of the embossed paper is in the range of between 0.02 and 2.00 mm, with the number of the projections being in the range of between 20 and 200 projections/cm 2 . Further, the sound absorbing surface material 6 is laminated onto a air permeable sheet of porous material 7, to manufacture a sound absorbing material 8.
