Abstract

The present invention relates to an electrospinning apparatus comprising a spinning tube having a plurality of spouting holes, in which the spinning tube which is rotatable and having a plurality of spouting holes instead of conventional nozzles is employed as means for electrospinning a spinning solution in the direction of a collector. According to the present invention, electrospinning is performed using both electrostatic force and centrifugal force, thereby increasing discharge amount of unit polygonal tube per unit time and thus significantly improving productivity. Compared to conventional electrospinning apparatuses that use nozzles, the necessity of replacing and cleaning nozzles is eliminated and production processes are thus simplified. As the collector is located above the spinning tube having the plurality of spouting holes, a phenomenon (drop phenomenon) in which the spinning solution in a solution state not a fibrous state drops onto the collector during electrospinning is prevented to improve the quality of the nanofiber web being produced.
