NOZZLE FOR ELECTROSPINNING AND METHOD FOR PRODUCING FINE THERMOPLASTIC RESIN FIBER USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a nozzle for electrospinning, which provides a fine thermoplastic resin fiber having a uniform diameter by a solution electrospinning method and to provide a method for producing a fine thermoplastic resin fiber using the same. SOLUTION: The nozzle for electrospinning has a constitution that a groove-shaped storage tank of a solution of a thermoplastic resin in a solvent and a lip part reaching from one end part of the storage tank of a solution of a thermoplastic resin in a solvent to one end of a conductive block body are formed on the surface of the conductive block body and the lip part is equipped with a plurality of fine flow channels which reaches from the storage tank of a solution of a thermoplastic resin in a solvent to the one end part of the conductive block body and overflows the solution of the thermoplastic resin in the solvent.
