The present invention relates to a floor carpet for an automobile and, more specifically, to a floor carpet for an automobile having excellent sound-absorbing and sound-blocking properties, wherein polyurethane foam having low density is applied to a sound-absorbing unit, and a thermoplastic elastic body having low surface density is applied to a sound-blocking unit to improve fuel efficiency of an automobile through weight lightening. Moreover, material properties are equally maintained at the same time.

본 발명은 자동차용 플로어 카페트에 관한 것으로, 보다 상세하게는 흡음재부에 저밀도의 폴리우레탄 폼을 적용하고, 차음재부에 면밀도가 낮은 열가소성 탄성체를 적용함으로써 경량화하여 차량 연비를 개선시키고, 물성 특성은 동등 이상을 유지하는 동시에 흡음 및 차음 성능이 우수한 자동차용 플로어 카페트에 관한 것이다.
