Nano-fiber manufacturing apparatus, the nano-fiber manufacturing method, and a nozzle for the nano-fiber manufacturing

摘要

PROBLEM TO BE SOLVED: To provide an apparatus and a method for manufacturing a nanofiber that can stably spins while easily manages the maintenance of a nozzle.;SOLUTION: An apparatus for manufacturing nanofiber comprises: an outflow body flowing a raw liquid in a space. The outflow body has a plurality of outflow hole in which the raw liquid passed therethrough and nozzles in which an opening portion, a tip end of the outflow hole, is linearly arranged. The nozzle is formed from a first separator having a first facing surface and a second separator having a second facing surface. The first facing surface has a plurality of first grooves, arranged parallel to each other, which has an entry end portion and an exit end portion. The outflow hole corresponding to the first groove is formed by overlapping the first facing surface with the second facing surface each other. The exit end portion of the first groove is positioned in an outside of such an overlapped shape with a predetermined length XM relative to a circumferential border line of such an overlapped shape formed from overlapping the first facing surface with the second facing surface.;COPYRIGHT: (C)2014,JPO&INPIT
