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.

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.

The present invention relates to a melt-blown fiber web having improved elasticity and cohesion, and a manufacturing method therefor. The objective of the present invention is accomplished by a melt-blown fiber web comprising a thermoplastic resin which comprises 10 to 60 wt % of thermoplastic resin microfibers and 40 to 90 wt % of non-circular cross-sectional hollow conjugated staple fibers with respect to the total weight of the fiber web.

A waved meltblown fiber web of the present invention relates to a fiber web prepared by a meltblown method and is characterized by a preparation method in which a meltblown microfiber comes in contact with collection portions having different surface velocities so as to be collected. The waved meltblown fiber web of the present invention is characterized in that: a part of meltblown microfibers reaches a low velocity collection portion so as to be horizontally layered, thereby forming a horizontal fiber layer (); another part of the meltblown microfibers reaches a high velocity collection portion of which the surface velocity is greater that of the low velocity collection portion so as to form a serpentine vertical fiber layer (); and the upper end of the vertical fiber layer () becomes entangled so as to form a wave shaped wave layer () forming the uppermost portion of the fiber web.

Method of preparing a meltblown fiber web

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.
