Abstract (en)
[origin: WO2007035011A1] 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.
