유지흡착률을 확보함과 동시에 흡착속도를 효과적으로 높일 수 있는 유지흡착용 나노 파이버 적층체, 유지흡착용 나노 파이버 집적체의 유지흡착률 추정방법 및 유지흡착후의 체적 추정 방법을 제공한다. 유지흡착용 나노 파이버 집적체（1）는 평균 섬유경 d가 1000nm이상 2000nm이하 이며, 겉보기 밀도 ρ가 0.01g/cm이상 0.2g/cm이하이다. 유지흡착용 나노 파이버 집적체(1)는 유지의 흡착률을 확보함과 동시에 흡착속도를 효과적으로 높일 수 있다. A fiber aggregate for sound insulation capable of effectively insulating sound by a simple structure and a sound absorbing and insulating material and a sound absorbing and insulating material for vehicles having the fiber aggregate for sound insulation are provided. The fiber aggregate for sound insulation has an average fiber diameter from 450 nm to 5800 nm and a bulk density from 0.09 g/cm3to 0.33 g/cm3. The fiber aggregate for sound insulation particularly preferably has an average fiber diameter from 450 nm to 1650 nm and a bulk density from0.09 g/cm3to 0.22 g/cm3. The fiber aggregate for sound insulation satisfying these numerical ranges is capable of achieving lightness in weight and exhibiting effective sound insulating performance.
