Abstract
The present invention relates to an electrospinning device. The electrospinning device may apply the force of a supersonic flow acting at a predetermined angle with respect to an electrostatic force on a fiber discharged from an electrospinning nozzle to cause shearing stress on the fiber, thereby providing fibers having a very small diameter and collecting fibers having a finer diameter. Also, the electrospinning device may collect finer and more uniform fibers by adjusting the relative positions of the electrospinning nozzle for discharging the fiber and a gas spray nozzle for spraying a gas.
