폴리우레탄 폼 시트 면에 부직포를 부착할 때 그 사이에 알루미늄 필름을 삽입하여 성형함으로써, 헤드 라이너의 중량 증가를 최소화하면서도 헤드 라이너의 열 차단 기능을 통해 핫멜트 필름으로 부착할 때와 비교하여 1.6℃ 정도 자동차 실내 온도를 낮춰 쾌적한 실내 환경을 조성할 수 있다. 특히, 알루미늄 필름에 점착제가 코팅된 것을 사용함으로, 폴리우레탄 폼 시트와 부직포를 쉽게 일체로 부착하여 헤드 라이너를 제작하고, 열 차단 기능을 통해 자동차 실내의 온도를 낮출 수 있다. 또한, 알루미늄 필름을 폴리우레탄 폼 시트의 양쪽 면에 각각 부착해서 일체로 제작할 수 있게 구성함으로, 두 번에 걸쳐 열 차단 효과가 이루어지게 하여 자동차 실내로 전해지는 열을 효율적으로 차단하여 쾌적한 실내 환경을 조성할 수 있다.

    When a non-woven fabric is attached to a surface of a polyurethane foam sheet, an aluminum film is inserted between and integrally formed with the non-woven fabric and polyurethane foam sheet so that an increase in weight of a headliner is minimized, and a temperature of a vehicle interior is lowered by about 1.6° C. as compared to a case of attaching a non-woven fabric using a hot melt film through a heat insulating function of the headliner, thereby providing a comfortable internal environment. In particular, the aluminum film coated with an adhesive is used to easily integrally attach the polyurethane foam sheet and the non-woven fabric to manufacture the headliner and lower the temperature of the vehicle interior through the heat insulating function. In addition, the aluminum film is attached to both surfaces of the polyurethane foam sheet and integrally manufactured with the polyurethane foam sheet so that a heat insulating effect is achieved twice, and thereby effectively insulating heat being transferred to the vehicle interior so as to form a comfortable internal environment.
