The present invention relates to a bottom-up electrospinning apparatus for producing microfibers having a thickness of nanoscale. The electrospinning device of the present invention is a spinneret main tank (1), a metering pump (2), a nozzle block (4), a collector (5) and a nozzle block (4) and a collector for integrating fibers radiated from the nozzle block. In the electrospinning device comprising the voltage generator 6 for applying a voltage to (5), (i) the outlet of the nozzle 4a provided in the nozzle block 4 is formed in an upward direction, and (ii) the collector (5) is located above the nozzle block, and (i) the spinning solution drop device 3 is installed between the spinning solution main tank 1 and the nozzle block 4. The present invention can mass-produce nanofibers and nonwoven fabrics thereof by maximizing the fiber forming effect during electrospinning, and prevents the spinning solution from dropping in the form of droplets without forming the fibers, thereby effectively preventing high quality nanofibers and Nonwovens can be produced. |
