| abstract |
The present invention relates to a process of preparing a continuous filament composed of a nano fiber, wherein nano fibers are prepared by spinning a polymer spinning dope in a spinning dope main tank ( 20 ) onto the surface of water or organic solvent ( 4 a ) of a collector ( 4 ), which contains water or inorganic solvent ( 4 a ) and has a conductive material ( 5 ) with a high voltage applied sunken in the water or organic solvent ( 4 a ), through nozzles ( 2 ) with a high voltage applied, and the nano fibers are pressed, drawn, dried and wound while being pulled by a rotary roller ( 6 ) rotating at a constant linear velocity from the location spaced more than 1 cm from one end of a dropping spot. The present invention can prepare a continuous filament composed of a nano fiber by an electrospinning method and a continuous process. |
