摘要
PURPOSE: Provided is an electrospinning device which enables the stable mass production of nano fibers with a stream control unit, and prevents the flow of discharge from being randomized and coagulated due to the electric interaction. CONSTITUTION: The electrospinning device comprises: a solution feeding unit(10) for feeding a solution where a high molecular fibrous material is dissolved in a solvent; a spinning nozzle pack(P) with a plurality of spinning nozzles to receive the fiber solution from the solution feeding unit and discharge it in the form of a filament; a voltage application unit(19) applying a predetermined voltage to the spinning nozzle pack to charge it; a jet-stream control unit(20) to be charged with the same polarity as the charged filament; a collector(21) to be charged with a polarity opposite to the charged filament such that the discharged filaments are collected thereon; a stream guide unit(22) for guiding the collection of the filaments; an air injection unit injecting an air between the spinning nozzle pack and the collector such that the volatility of the solvent contained in the charged filaments is heightened; and a solvent exhaust unit(23) absorbing the solvent from the air film between the spinning nozzle pack and the collector.
