Patent ID: 7931456

Claim:
A fiber spinning apparatus, comprising: a polymer supply vessel connected to an inlet side of a spinneret having a polymer flow passage disposed therein, said polymer flow passage exiting said spinneret through at least one spinning nozzle; forwarding gas nozzles having exits disposed adjacent to and directed toward said spinning nozzle, said spinning nozzle extending beyond the exits of said gas nozzles; at least one electrode disposed downstream of said gas nozzles, but outside of a gas flow path established by the direction of the gas flow nozzles; and a fiber collector disposed downstream of said spinning nozzle, wherein each of said electrode and said fiber collector are electrically connected to a circuit containing a high voltage supply, such that each can be individually charged to a potential, and the spinneret is grounded, and the spinning nozzle has a tip, said tip having an angular geometry such that an electric field is caused between the tip and the electrode.
