Electrospinning Device For Manufacturing Nanofiber

Abstract

The purpose of the present invention is to provide an electrospinning device for manufacturing a nanofiber, the device comprising multiple units arranged successively, wherein units for ejecting a hot melt and units for ejecting a polymer spinning solution are installed alternately, the hot melt is ejected onto a substrate from nozzle blocks of the hot melt units positioned on the front end, and the polymer spinning solution is electrically spun onto the substrate, to which the hot melt has been ejected, from nozzle blocks of the spinning solution units positioned on the rear end, thereby stacking a nanofiber web. Accordingly, the nanofiber web can be easily attached to the substrate; the device is applicable both to an upward electrospinning device and a downward electrospinning device; the holt melt is not only ejected separately from the polymer spinning solution but also is repeatedly ejected to specific areas and parts on the substrate, thereby substantially reducing use of the hot melt; interference of the hot melt with the nanofiber web is minimized concurrently with substantially reducing use of the hot melt, thereby improving the performance and quality of the nanofiber or the nanofiber filter; the hot melt can not only be ejected onto the substrate through each unit, but the same or different kinds of polymer spinning solutions can be electrically spun, thereby manufacturing various materials and kinds of nanofibers and nanofiber filters, and enabling mass production of nanofibers and nanofiber filters.
