The present invention relates to a lightweight sound absorbing material and a substrate attached therewith. More specifically, the present invention relates to: a lightweight sound absorbing material which uses a triple thin film fiber layer having fine fiber layers on an upper surface and a lower surface of fiber non-woven fabric, thereby being light and providing superior sound absorbing performance compared to a conventional sound absorbing material; and a substrate attached therewith.
본 발명은 경량 흡음재 및 이를 부착한 기재에 관한 것으로, 보다 상세하게는 섬유 부직포 상면 및 하면에 미세 섬유층이 적층된 3중의 박막 섬유층을 이용하여 기존의 흡음재에 비하여 가벼우면서도 우수한 흡음 성능을 제공하는 경량 흡음재 및 이를 부착한 기재에 관한 것이다.
