Abstract: Disclosed is a melt-blown fiber web with improved concentration force and elasticity, whereby a melt-blown fabric is cut and sealed at predetermined intervals using knives having arbitrary patterns so that concentration force and elasticity of the melt-blown fiber web can be improved without degrading the inherent function of the fiber web. Further disclosed are a method and apparatus for manufacturing the melt-blown fiber web. The melt-blown fiber web includes thermoplastic filaments, wherein cutting portions and sealing portions are arranged on top and bottom surfaces of the fiber web at predetermined intervals along a thickness of the fiber web so that a concentration force and elasticity of the fiber web are improved.

Abstract: The present invention relates to an apparatus and a method for manufacturing a vehicle dash isolation pad. The method includes bonding a microfiber sound absorbing material to an adherend by using latent heat of a preheated adherend. As such, the vehicle dash isolation pad with improved weight reduction, sound absorption, and sound insulation effects can be obtained.

Abstract: A multi-layered noise absorbing and insulating material includes a noise insulation material having opposing first and second major surfaces. The noise insulation material includes an adhesive resin including an air permeability-forming material. A first noise absorption material is adhered to the first major surface of the noise insulation material. A second noise absorption material is adhered to the second major surface of the noise insulation material. The multi-layered noise insulation absorbing and insulating material has air-permeability.

Abstract: A method of manufacturing a wheel guard may include injection-molding an adhesive layer, bonding an outer layer including a non-woven fabric and a sound-absorbing layer including thermoplastic resin with the adhesive layer in between, and forming the layers into a predetermined shape of the wheel guard, with the outer layer and the sound-absorbing layer bonded by the adhesive layer. The thickness of the outer layer may be 2 to 10 mm, the thickness of the adhesive layer may be 0.1 to 2 mm, and the thickness of the sound-absorbing layer may be 2 to 10 mm, before the bonding. A specific heat treatment layer may be formed on a non-adhesive side of the outer layer and may have an LM FIBER, a film, or a sheet.
