  • Publication number: 20140182779
    Abstract: A method of continuously producing an opened fiber bundle for a cleaning member while conveying a fiber bundle, includes the steps of applying a tensile force to the fiber bundle; relaxing the tensioned fiber bundle to open the fiber bundle; and blowing air in a direction intersecting with the machine direction of the belt-shaped fiber bundle through an air outlet of an air feeder, to further open the belt-shaped fiber bundle and widen the belt-shaped fiber bundle in the width direction. An outer portion in the width direction of the air outlet is disposed downstream in the machine direction, compared with an inner portion in the width direction of the air outlet.

  • Patent number: 8753672
    Abstract: The present application discloses an alternative method for the formation of non-woven with fibers in the 1 to 200 ?m range. Using an aqueous solution of gelatin (optionally with <30% of low molecular weight alcohol) the fibers are ejected utilizing pressurized air emitted from nozzle and the non-woven formed directly from the emitted thin fibers. The gelatin non-woven can be cross-linked by heat-treatment or chemical cross-linking, and the non-woven is biocompatible as measured by fibroblast growth in vitro and wound healing on pigs in vivo.

  • Patent number: 8685312
    Abstract: A melt spinning apparatus includes an apparatus body, a nozzle configured to extrude melted resin in the apparatus body, and a barrel having an air discharge passage arranged around this nozzle to discharge hot air. The discharge passage includes a sloped passage and a parallel passage that extends along the nozzle. At an intersection of imaginary lines extending along the centerlines of the sloped passage, an imaginary merging section is defined. An open end of the nozzle is positioned on the downstream side of the imaginary merging section of the hot air blown diagonally forward toward a periphery of the nozzle. To manufacture a sheet of a nonwoven fabric, the melted resin is discharged from the nozzle and then the hot air swirling diagonally forward is blown toward the periphery of the nozzle. This causes the melted resin to be formed into spiral fibers. Those fibers are blown onto the belt of a conveyor belt apparatus to manufacture a nonwoven fabric sheet.

  • Patent number: 8685311
    Abstract: A melt spinning apparatus includes an apparatus body and a nozzle for extruding melted resin, a primary hot air passage formed around the nozzle, and a secondary hot air passage formed in a zone outside of the primary hot air passage, which are formed in the apparatus body. The primary hot air passage discharges primary hot air onto fibers of the melted resin extruded from the nozzle. The secondary hot air passage discharges secondary hot air to maintain the temperature of the primary hot air. The discharge angle of the secondary hot air from the secondary hot air passage is set in a range of 0° to 50° with respect to the direction of the melted resin extruded from the nozzle. The secondary hot air forms an air curtain that blocks the atmospheric air.
