Abstract

The present invention relates to an electrospinning apparatus, and the purpose of the present invention is to provide an electrospinning apparatus capable of producing nanofiber having various ingredients and thicknesses by controlling the temperature of at least one solution discharged from nozzles mounted on the tubular bodies of a nozzle block and thus controlling the viscosity of the solution which is electrospun; producing nanofiber having uniform quality without applying a density difference and a voltage difference by disposing the front end portions of the nozzles in a flare shape; and mass-producing nanofiber at a low cost as well as reducing the amount of the solution used by removing an overflow prevention system and using a metering pump alone or by using the metering pump and the overflow prevention system alternatively or in a hybrid manner.

Description

TECHNICAL FIELD

[0001] The present invention relates to an electrospinning apparatus, and more particularly by controlling solution temperature from nozzle equipped on nozzle block tubular bodies, controlling electrospin solution viscosity, nanofiber with various components and thickness could be manufactured, nozzle block front-end is arranged in divergent shape, there aren't density difference and voltage difference, nanofiber with uniform quality could be produced, only using metering pump, or by alternatively using metering pump and overflow prevent system, solution usage amount is decreased, and simultaneously mass-producing nanofiber in low cost.BACKGROUND ART

[0002] Generally, Electrospinning is technology producing micro diameter fiber by spinning fiber material solution in charging state, recently nanometer fiber (below, ‘nanofiber’) could be manufactured, and research regarding this is actively in progress. Nanofiber produced by electrospinning means fiber having average diame...

Examples

embodiment 1

[0164]According to a nanofiber manufacture device which features 20% of front-end of nozzle of nozzle block in flare shape, distance between electrode and nozzle is 40 cm, applied voltage is 20 kV, spinning solution flow is 0.1 mL / h, temperature is 22° C., humidity is 20% and produces nanofiber nonwoven by electrospinning.

[0165]In this case, as there is no interference among nozzles, nanofiber non-fabric collected in predetermined discharging amount on a collector could be produced.

[0166]Meanwhile, the electrospinning apparatus (1) of the present invention, as illustrated in FIGS. 13 and 14, provided a metering pump, or provided a metering pump and overflow system, controlling polymer solution amount, not integrated to the collector, minimize amount attached to the nozzle, simultaneously minimize polymer solution consumption.

[0167]In other words, as illustrated in FIG. 13, the collector (20) of the electrospinning apparatus (1) comprising an electric conductor, through an insulator ...
