The present invention relates to a method for manufacturing a nanofiber using an electrospinning combined with a centrifugal force, the method comprising the steps of: supplying spinning liquid to a spinning unit constituted of an internal tube (a) and an external tube (b) forming a concentric circle to define a gap between the internal tube (a) and the external tube (b); and rotating any one among the internal tube (a) and the external tube (b) and fixing the remainder to spin the supplied spinning liquid in a nanofiber form at an end of the rotated tube. At this time, grooves (W) is spaced throughout the whole length of the tube at one side facing the gap, among both sides of the rotated tube and s formed along a width direction of the tube, thereby playing a role as a storage tank of the spinning liquid. In the present invention, since a nanofiber is formed from spinning liquid by using a spinning unit defined by a concentric circle formed by the internal tube and the external tube instead of a nozzle, a cumbersome work can be omitted such as a nozzle cleaning. In the present invention, and since an electrostatic force and a centrifugal force is concurrently are used, a nanofiber is formed on an end of one rotated tube among the external tube and the internal tube constituting the spinning unit, and thus a place where the nanofiber is formed, thereby efficiently producing the nanofiber. |
