摘要： Disclosed are an undercover for vehicles with high elasticity and rigidity and a method of manufacturing the same. The undercover for vehicles with high elasticity and rigidity may include a needle-punched nonwoven fabric having a multi-layer structure of felt layers including a first PET fiber and a low-melting-point PET fiber, and each of the felt layers may have improved tensile strength and have optimized fiber alignment, to thereby improve the binding between fibers, mechanical rigidity and elasticity, as well as to reduce the weight of components, improve durability and secure harmlessness and inline workability.

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.
