Title:
ELECTROSPINNING DEVICE AND MANUFACTURING METHOD OF FIBER
Document Type and Number:
Japanese Patent JP2023152179
Kind Code:
A
Abstract:
To provide an electrospinning device and a manufacturing method of a fiber, capable of suppressing deposition of a molten resin to an open end of a jet port while elevating wind velocity of a gas flow.SOLUTION: An electrospinning device 10 of the present invention includes: a nozzle 31 having an open end part for discharging a molten resin; an electrode 34 for forming an electric field between itself and the nozzle 31; and a gas jet part for ejecting a first gas flow A between the nozzle 31 and the electrode 34. The gas jet part includes: a first gas channel 40 arranged so as to surround the nozzle 31 and circulating the first gas flow A heated via a space formed in a space with an outer peripheral surface of the nozzle 31 to a discharge direction of the molten resin; and a jet port 41d for ejecting the first gas flow A circulating in the first gas channel 40 to the outside. An open end part of the jet port 41d has the smallest inner diameter among inner diameters of the first gas channel 40. The open end part of the nozzle 31 is arranged at a position projecting from an open end face of the jet port 41d.SELECTED DRAWING: Figure 2
