Patent ID: 8747093

Claim:
An electrostatic spinning apparatus for producing nanofibres from a viscous liquid in an electric field comprising: a charged electrode including at least one spinneret including a plurality of annular loops radially centred about and axially spaced along a central axis, wherein the annular loops are integrally connected to form a helical coil; a counter electrode spaced apart from the charged electrode; a liquid reservoir for holding a viscous liquid, the reservoir being in liquid communication with at least one surface of the spinneret; and a power supply electrically connected between the charged electrode and the counter electrode, the power supply capable of electrically charging the charged electrode and supply a potential difference between the charged electrode and the counter electrode, wherein the liquid reservoir comprises a liquid bath in which a portion of the spinneret is immersed, the spinneret being configured to rotate about the center axis (X-X) in order to coat a portion of the viscous liquid on a surface of the spinneret and move that coated surface out from the liquid reservoir.
