Abstract
The present invention relates to an apparatus of polymer web by electrospinning process and manufacturing method thereof, which can manufacture porous polymer web using an electrospinning method. The method for manufacturing porous polymer web by electrospinning process includes the steps of: forming, pressurizing and supplying at least one or more kinds of polymer materials in a liquid state; and discharging and piling the polymer materials to a collector through one or more charged nozzles, the collector being located under the nozzles and charged to have a polarity opposed to the polarity of the charged nozzles, the collector moving in a prescribed speed.
