Abstract
It is important for automobile manufacturers to eliminate unwanted noise in passenger compartments of vehicles. One of the methods free from noise is to use sound absorbing materials such as floor coverings, package trays, door panels and luggage compartments in auto interiors. In this study, the needle punched nonwovens were produced with the various blending ration of Non-circular shaped polyester, 2 denier and splittable micro-fiber, 2 denier. The sound absorption characteristic of nonwovens and corresponding mechanical properties are explored.
