간단한 구조로 효과적으로 차음할 수 있는 차음용 섬유 집적체, 이 차음용 섬유 집적체를 구비하는 흡차음재 및 차량용 흡차음재를 제공한다. 차음용 섬유 집적체는 평균 섬유경이 450nm ~ 8500nm이며, 겉보기 밀도가 0.09g/cm3 ~ 0.33g/cm3이다. 차음용 섬유 집적체는 평균 섬유경이 450nm ~ 1650nm이며 겉보기 밀도가 0.09g/cm3 ~ 0.22g/cm3인 것이 특히 바람직하다. 차음용 섬유 집적체는 이 수치범위들을 만족함으로써 경량이면서 효과적으로 차음성능을 발휘할 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.
