Abstract
The present invention provides a nanofiber manufacturing method and a nanofiber manufacturing device. A solutionin which a polymer is dissolved in a solvent is supplied from a distal end of a nozzleto form a Taylor coneat a distal end opening. By applying a voltage between the solutionand a collectorusing a power supply portion, an electrospinning jetis sprayed from the Taylor coneto the collector. At the start or stop of electrospinning, a blocking memberis inserted into a spraying areaof the electrospinning jetsuch that an unstable electrospinning jet or unstable nanofibers are received. A product is not manufactured from an unstable electrospinning jet formed at the start or stop of electrospinning, and the manufacturing of a defective product is prevented.
