  • Publication number: 20210062377
    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.

  • Patent number: 9469092
    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.

  • Patent number: 9249527
    Abstract: Disclosed is a method and apparatus for manufacturing a melt-blown fabric web, by which a melt-blown fabric web having improved filament cohesion and excellent bulky characteristics and sound-absorbing performance is manufactured. The apparatus includes a heat extruder for heating a thermoplastic resin composition and extruding the melted thermoplastic resin, a melt-blown fiber spinner for spinning the extruded thermoplastic resin as a melt-blown fiber in a filament form, a variable gas injector for injecting gas whose injection speed and injection quantity are continuously changed at random to the melt-blown fiber spun from the melt-blown fiber spinner to cause the injected gas to collide with the spun melt-blown fiber, and a collector for collecting the melt-blown fiber, which is spun from the melt-blown fiber spinner and collides with the gas, to form a melt-blown fabric web.
