NANOFIBER SPINNING METHOD AND DEVICE

摘要

A nanofiber spinning method and device for manufacturing a uniform yarn of nanofibers with high strength at low cost with high productivity. A nanofiber producing unit (2) for extruding a polymer solution prepared by dissolving a polymer substance into a solvent from small holes (7), charging the nanofibers, stretching them by electrostatic explosion to produce nanofibers (11), and flowing them in one direction, an aggregating electrode unit (3) for attracting the produced nanofibers (11) while applying a voltage with a potential difference from that of the charged polymer solution, rotating and twisting the nanofibers (11) to aggregate theminto a yarn (20) composed of the nanofibers (11), and a collecting unit (5) for winding up the yarn (20) passing through the central part of the aggregating electrode unit (3).
