METHOD FOR PRODUCING NANO-FIBER AND APPARATUS FOR PRODUCING NANO-FIBER

摘要

PROBLEM TO BE SOLVED: To provide a method for producing nano-fibers by which the solution cutting off of a polymer solution at a discharge port is good. SOLUTION: The polymer solution is discharged from the discharge port 25 to which a high voltage is applied and drawn by electrostatic explosion to deposit the nano-fibers. In the process, the solution sagging of the polymer solution from the discharge port 25 is avoided by moving a piston of a jetting apparatus 12 in the direction opposite to the solution extruding direction when deposition of the nano-fibers is stopped.
