Patent ID: 8562326

Claim:
An electrospinning apparatus for producing nanofibers, comprising: a spinning solution supply unit ( 10 ) for supplying a spinning solution formed by dissolving a nanofiber source in a solvent; a spinning unit ( 30 ) that includes a plurality of spinning nozzles ( 32 ) for spinning the spinning solution from the spinning solution supply unit ( 10 ) to a spinning zone (Z) under the spinning unit ( 30 ), and a nozzle block ( 31 ) in which the spinning nozzles ( 32 ) are equidistantly arranged and supported; a nanofiber-collecting unit ( 40 ) facing the spinning nozzles ( 32 ) of the spinning unit ( 30 ) to collect nanofibers spun from the spinning unit ( 30 ); a power supply ( 50 ) which forms an electric field in the spinning zone (Z) between the spinning unit ( 30 ) and the nanofiber-collecting unit ( 40 ) to apply electrical tensile force to the nanofibers spun from the spinning unit ( 30 ); a process gas supply unit ( 20 ) which generates and supplies process gas to control temperature and humidity of the spinning zone (Z) to a range appropriate for electrospinning conditions for nanofibers; and a process gas laminar flow distribution device ( 100 ) which fractionates the process gas supplied from the process gas supply unit ( 20 ), into laminar flows within the process gas laminar flow distribution device ( 100 ), and distributes the process gas from an upper portion of the spinning unit ( 30 ) to the spinning zone (Z).
