ELECTROSPINNING APPARATUS COMPRISING SPINNING TUBES HAVING PLURALITY OF DISCHARGE HOLES

摘要

The present invention relates to an electrospinning apparatus comprising spinning tubes having a plurality of discharge holes, the apparatus being characterized by using the rotating spinning tubes having a plurality of discharge holes, instead of conventional nozzles, as equipment used for electrospinning a spinning solution in the direction of a collector. The present invention increases the discharge amount per unit polygonal tube per unit time and thus significantly improves productivity by electrospinning using both electrostatic force and centrifugal force; compared to using nozzles, simplifies the production process by removing the inconvenience of replacing and cleaning the nozzles; prevents the occurrence of a (drop) phenomenon, in which the spinning solution drops onto the collector in a solution state, not a fibrous state, during the electrospinning, by locating the collector over the spinning tubes having a plurality of discharge holes; and thus improves the quality of the nanofiber webs being produced.
