Abstract:
1. A method for producing nanofibers, comprising: rotating a container on a shaft center of the container, the container provided with a plurality of small holes formed in a circumferential surface of the container, and the container being filled with a polymer solution made by dissolving a polymer material in a solvent, while an electric field generated by a high voltage generator is applied to a spinning space formed between the container and a ring electrode surrounding the container; discharging the polymer solution through the plurality of small holes of the rotated container utilizing centrifugal force and application of an electric field to produce electrically-charged fibers; discharging the electrically-charged fibers from the spinning space by air blow; and drawing the discharged electrically-charged fibers by an electrostatic explosion.
