Electrospinning apparatus

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...

Benefits of technology

[0037]The present invention having the composition stated above, by controlling one or more polymer solution viscosity by equipped a temperature adjusting device in each tubular body of a nozzle block, electrospinning nanofiber with various thickness and various components is discharged, thereby nanofiber with various thickness and various components could be manufactured, manufacturing process is simplified and simultaneously manufacture cost is down, nanofiber having uniform quality could be manufactured. Also by adjusting polymer solution amount, amount of polymer solution attached to a nozzle, which is not integrated to a collector, is minimized and simultaneously polymer solution consumption is minimized, and mass-producing nanofiber is possible in low cost.

Problems solved by technology

Therefore, in order to manufacture nanofiber with constant fiber diameter distribution, spinning room temperature and humidity should be controlled to maintain constantly according to given condition, for this, there are drawbacks such as equipment expense and energy expense cost a lot.

In the case of manufacturing such multiple layer nanofiber, there is strong point such as enhanced nanofiber is manufactured, but relatively nanofiber thickness becomes thicker, when polymer solution electrospin and integrated to a collector, as one polymer solution is used, there is problem that two or more electrospinning apparatus are needed, and there are problems such as installation expense and energy expense cost a lot, manufacture line becomes longer, and processing time is increased.

When manufacturing a product by electrospinning through the electrospinning apparatus, regarding a nozzle among important factors determining a product feature, by manufacturing nanofiber using one or few nozzle, production speed is very low so it is difficult to commercialize.
