摘要： Nanofibers are formed from a polymer material by rotating a conductive rotating container having a plurality of small holes while supplying a polymer solution formed by dissolving a polymer material in a solvent into the rotating container, charging the polymer solution discharged from the small holes of the rotating container by charging means, and drawing the discharged filamentous polymer solution by centrifugal force and an electrostatic explosion resulting from evaporation of the solvent. The nanofibers from this production step are oriented and made to flow from one side toward the other side in a shaft center direction of the rotating container by a reflecting electrode and/or blowing means, or those nanofibers are deposited, to produce a polymer web. The nanofibers and the polymer web using these nanofibers can be produced uniformly by a simple configuration with good productivity.

摘要： A container having a plurality of orifices in an outer peripheral wall and having a space communicating with the orifices is rotated to extrude an electrically charged raw material liquid containing a polymer material from the space through the orifices by centrifugal force. This allows the electrically charged raw material liquid to form a fibrous material. At this time, the raw material liquid is supplied to the space in which the raw material liquid is filled by a raw material liquid pump so that the raw material liquid is extruded from the orifices at a predetermined pressure. That is, the raw material liquid in the space is pressurized. Also, the shape of the space in the container is set so that the centrifugal force exerted on the raw material liquid is constant.
