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： Disclosed are, inter alia, a sound absorption and insulation material including a polyester hollow fiber, a polyester low-melting-point composite fiber and a polyester base fiber, a sound absorption and insulation pad for a floor including the same, and a manufacturing method thereof for improving the elasticity and sound absorption and insulation performance of the sound absorption and insulation material. The sound absorption and insulation material is an environmentally friendly material that can reduce discomfort due to the generation of volatile organic compounds (VOCs) and the emission of toxic gases during combustion. Also, the sound absorption and insulation pad including the sound absorption and insulation material can exhibit superior sound absorption performance, sound insulation performance and actual vehicle performance compared to a conventional sound absorption and insulation pad of the same thickness.

摘要： A composite fiber web having superior heat resistance and sound absorption and including a center layer containing a carbon fiber and a heat-resistant layer, and to a method of manufacturing the same. The method of the present invention can exhibit a fast manufacturing speed through a melt-blowing process that will generate economic benefits. The composite fiber web includes a composite layer and individual layers with various fiber diameters resulting in a superior sound absorption rate. The PET fiber included in the heat-resistant layer of the composite layer is an environmentally friendly material with superior heat resistance due to the inclusion of ultrafine fiber. Also, the composite fiber web has superior strength, conductivity, and electromagnetic shielding and deodorization effects, which allows it to be widely utilized for sound absorption materials and in all application fields thereof.
