Embodiment Construction

[0058] Embodiments of the nanofiber manufacturing apparatus and the nonwoven fabric manufacturing apparatus of the present invention will be described together below.

[0059] (Embodiment 1)

[0060] figure 1 It is a perspective view schematically showing the nonwoven fabric manufacturing apparatus of the present invention.

[0061] As shown in the figure, the nonwoven fabric manufacturing apparatus 100 has a nanofiber manufacturing apparatus 101, a partition wall 102, a gas supply source 103, an exhaust device 105 as an exhaust mechanism, and a compression mechanism 300. In addition, since the nanofibers during manufacture or their raw material solutions cannot be clearly distinguished, they are all marked with 200 , and the manufactured nonwoven fabric is marked with 210 .

[0062] The nanofiber 200 can be selected from petroleum-based polymer materials such as polyvinylidene fluoride (FVDF), polyvinylidene fluoride-hexafluoropropylene copolymer, polyacrylonitrile, or the...

Abstract

Provided is a nano-fiber manufacturing apparatus, which manufactures nano-fibers by using an electrostatic explosion but which has a very low possibility of explosion even if it uses an inflammable solvent. The nano-fiber manufacturing apparatus (101) comprises injection means (110) for injecting a raw material liquid (200) for the nano-fiber (200) into a manufacturing space, in which the nano-fiber (200) is manufactured by the electrostatic explosion of the raw material (200), and charging means for charging the material liquid (200). The manufacturing apparatus (101) further comprises a gasfeeding source (103) for feeding a safety gas to change the manufacturing space, into which the material liquid (200) is injected, into a low-oxygen atmosphere, and a partition (102) for keeping the manufacturing space in an atmosphere of a lower oxygen concentration than that of the atmosphere of the ambient space.

Description

technical field [0001] The present invention relates to a nanofiber manufacturing device that uses electrostatic explosion to manufacture nanofibers and collects the nanofibers, and more particularly relates to a nanofiber manufacturing device that uses a raw material solution that requires explosion-proof measures to manufacture nanofibers. Background technique [0002] An electrospinning method is known as a method for producing a filamentary substance (hereinafter referred to as "nanofiber") composed of a polymer substance and having a diameter of a submicron scale. [0003] This electrospinning method is a method in which nanofibers are obtained by flowing (spraying) a polymer solution in which a polymer substance is dispersed in a solvent from a needle nozzle to which a high voltage is applied, into a manufacturing space. More specifically, a high voltage is used to increase the charge density of the charged polymer solution as the solvent evaporates. Then, when the Co...
