Title:
NANOFIBER MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2016/035473
Kind Code:
A1
Abstract:
In the present invention, a solution obtained by dissolving cellulose acylate in a solvent is emitted from the leading-end opening of a nozzle. In the solution emitted from the leading-end opening, the saturated vapor pressure Ps of the solvent and the concentration of the cellulose acylate satisfy Ps×C≤300. Voltage is imparted to the nozzle and a collector, and the solution and the collector are thereby charged with reversed polarities. Through the use of the collector, the solution emitted from the leading-end opening is drawn out and accumulates as a nanofiber.
