NANOFIBER PRODUCING APPARATUS AND NANOFIBER PRODUCING METHOD

摘要

PROBLEM TO BE SOLVED: To produce a nonwoven fabric of a nanofiber by using an electrospinning method, which has uniform thickness even at an end part.SOLUTION: This nanofiber producing apparatus comprises: nanofiber production means for producing a nanofiber by drawing a raw material liquid with the use of electrostatic force in a space; collecting means for depositing the nanofiber produced in the space on a belt-like substrate to form the nanofiber into a belt-like nonwoven fabric, and collecting the nonwoven fabric; and end face treatment means for removing an end part in a width direction of the nonwoven fabric.
