Conjugate Electrospinning Devices, Conjugate Nonwoven and Filament Comprising Nanofibers Prepared by Using the Same

摘要

Discloses are a conjugate electrospinning devices for preparing fibers (nanofibers) having a nano-level thickness, and nanofibers prepared using the same. The conjugate electrospinning devices comprises: spinning dope main tanks ( 1 ); metering pumps ( 2 ); a nozzle block ( 4 ); nozzles ( 5 ) aligned on the nozzle block; a collector ( 7 ) for collecting fibers spun from the nozzle block; and a voltage generator ( 9 ) for applying a voltage to the nozzle block and the collector ( 7 ), wherein [I] nozzles for spinning two or more different kinds of spinning dope are aligned on a nozzle block ( 4 ) regularly or in random order in repetitive units at the same ratio or in different ratios, aligned in random order at a predetermined ratio, or aligned thereon in random order at a predetermined ratio, or aligned thereon repetitively; [II] the number of the spinning dope main tanks ( 1 ) is two or more; and [III] a spinning dope drop device ( 3 ) is arranged between the spinning dope main tanks ( 1 ) and the nozzle block ( 4 ). Since two or more different kinds of spinning dopes are combined and electrospun, and thus the physical properties (features) of a non-woven fabric and a filament can be easily managed by a simple process. Nanofibers and their non-woven fabrics can be mass produced because the fiber formation effects are maximized.
