Patent ID: 7351052

Claim:
An apparatus for producing nanofiber utilizing electrospinning comprising: a supply unit for supplying polymer materials of the liquid state used to produce fibers; a spinning unit having at least one spinning nozzle pack in which a plurality of spinning nozzles for discharging the polymer materials supplied by the supply unit in a charged filament form are arranged in series; a collector installed below the spinning unit for piling the charged filament discharged by the spinning unit in a specific thickness; a control unit charged to have a voltage of same polarity as one of the charged filament and positioned at both longitudinal sides of the spinning nozzle pack for guiding the stream of the charged filament in order to prevent repulsion and dispersion of the charged filaments discharged from spinning nozzles installed at both ends of the spinning nozzle pack; an induction unit positioned between the control unit and the collector to surround the filament stream for inducing the charged filament stream passing through the control unit toward the collector, a voltage of same polarity and same value as the control unit being applied to the induction unit; and a carrier unit for carrying a pilling material to which the charged filament is to be adhered and which is positioned above the collector.
