The present invention relates to a polyester sound-absorbing material with improved moldability and light weight, and a method for manufacturing a molded product using the same. Specifically, the present invention provides a polyester sound-absorbing material that can be molded by integrating a skin member and the sound-absorbing material without the need to attach a separate sound-absorbing material on the skin member by using felt including a polyester-based basic fiber, a low-melting-point polyester-based adhesive fiber, and a polyester-based hollow fiber.

    본 발명은 성형성 및 경량성이 향상된 폴리에스테르 흡음재 및 이를 이용하여 성형물을 제조하는 방법에 관한 것이다. 구체적으로 본 발명은 폴리에스테르계 기본 섬유, 저융점 폴리에스테르계 접착 섬유 및 폴리에스테르계 중공 섬유를 포함하는 펠트를 이용하여 스킨 부재상에 별도의 흡음재를 부착할 필요없이 스킨 부재와 흡음재가 일체화하여 성형될 수 있는 폴리에스테르 흡음재를 제공하는 것이 특징이다.
