The present invention forms a hood insulation by forming grains on at least one surface layer exposed to the outside of the surface layer of the hood insulation. Accordingly, an object of the present invention is to provide an automotive hood insulation which can improve sound absorbing performance in an engine room, while enhancing customer satisfaction by making the surface of the hood insulation luxurious. In particular, although the grain can be directly formed on the surface layer of the present invention, the grain can be transferred to a cavity of a mold for integrally forming a sound-absorbing layer and the surface layer. Therefore, the other object of the present invention is to provide the automotive hood insulation which can omit a process of forming grains by separately forming the sound-absorbing layer and the surface layer.

    본 발명은 후드 인슐레이션의 표층 중에서 후드에 장착했을 외부에 노출되는 적어도 한쪽 표층에 엠보(Grain)를 형성하여 후드 인슐레이션을 구성하므로, 엔진룸 내에서의 흡차음 성능을 개선하면서도 후드 인슐레이션의 표면이 고급스러운 느낌이 들게 하여 고객 만족도를 높일 수 있게 한 자동차용 후드 인슐레이션을 제공하는 데 그 목적이 있다. 특히, 본 발명은 표층에 직접 엠보를 형성할 수도 있으나, 흡음층과 표층을 일체로 성형하는 금형의 캐비티에 엠보를 전사할 수 있게 구성하므로, 흡음층과 표층을 일체로 성형하는 과정을 통해 별도로 엠보를 형성하는 과정을 생략할 수 있게 한 자동차용 후드 인슐레이션을 제공하는 데 다른 목적이 있다.
