摘要： Disclosed are a sound-absorbing material with improved sound-absorbing performance and a method for manufacturing the sound-absorbing material. The sound-absorbing material may improve sound absorption coefficient and transmission loss by forming large surface area and air layer, so as to induce viscosity loss of incident sound energy, and may provide light-weight design of a sound absorbing part or material since sound-absorbing performance may be substantially improved using reduced amount of fiber. Further, the sound-absorbing material may improve sound-absorbing performance by using binder fiber having rebound resilience, so as to maintain enough strength between fibers and also to maximize viscosity loss of sound energy transmitted to fiber structure.

摘要： The present invention provides a multilayer dash isolation pad having superior formability and sound absorption performance. The multilayer dash isolation pad includes a decoupler and a sound absorption and insulation layer. The decoupler is a soft felt manufactured from urethane foam or octalobal cross-section fiber, and the sound absorption and insulation layer includes a compressed felt manufactured from octalobal cross-section fibers. In particular, the shape factor (α) of the octalobal cross-section fiber is 2.0 to 2.7. Particularly, the multilayer dash isolation pad according to the present invention does not decrease thickness or be contracted upon press molding after pre-heating felt, such that superior formability in components can be obtained and a sound absorption coefficient may be enhanced without increase in the weights and thicknesses of the decoupler and the sound absorption and insulation layer.
