Abstract: Disclosed are a method of manufacturing a continuous filament by electrospinning, and a continuous filament manufactured thereby. Electrospun nano fibers 4 are collected on a collector 7 by electrically spinning a polymer spinning dope in a spinning dope main tank 1 onto the collector 7, which is a disk-shaped conductive material with a high voltage applied thereto and which rotates at a rotational linear velocity of 5 m/sec or more, through nozzles 2 having a high voltage applied thereto, and then the nano fiber 4 collected on the collector 7 are prepared in the form of a continuous filament by use of a collecting roller 11, and then the nano fibers 4 are (I) put in a canvas 14 through a traverse 13, or (II) dried, drawn, and wound consecutively.The continuous filament is superior in terms of drawing properties because nano fibers are arranged well in a filament axis direction, the continuous filament composed of nano fibers can be prepared by a continuous procedure, and the prepared continuous filament is useful as materials for various industrial fields, such as artificial leather, filters, and so on.
