Abstract:
An apparatus of polymer web by electrospinning process, the apparatus comprising:a barrel storing at least one or more kinds of polymer materials in a liquid state; a pump pressurizing and supplying the polymer materials of the liquid state stored in the barrel; a spinning part for injecting the polymer materials of the liquid state supplied by the pump through at least one or more charged nozzles and manufacturing thin fibers, the spinning part further comprising: a base having an inlet pipe formed at the center and a path for passing the polymer materials of the liquid state within, the inlet pipe receiving the polymer materials of the liquid state from the pump; a base conductor board attached on a lower surface of the base and having a conductive plate for transferring electric charge, the base conductor board having a plurality of nozzle taps for mounting the nozzles at a lower surface thereof; at least one or more nozzles mounted on the nozzle taps formed on the base conductor board for discharging the polymer material; a charge distribution board mounted on a lower portion of the base conductor board, the charge distribution board having a plurality of holes formed at the positions, where the nozzles are mounted, for passing the nozzles; and a conductor board mounted on a lower portion of the charge distribution board for charge distribution; a first high voltage generator providing electric charge for charging the polymer materials discharged through the at least one or more nozzles of the spinning part to have one polarity; and a collector for piling and transferring the thin fibers to form the polymer web, the collector being charged to have a polarity opposed to the polarity of the spinning part and to the charged fibers discharged by the nozzles.
