Abstract
An improved electroblowing process is provided for forming a fibrous web of nanofibers wherein polymer stream is issued from a spinning nozzle in a spinneret with the aid of a forwarding gas stream, passes an electrode and a resulting nanofiber web is collected on a collector. The process includes applying a high voltage to the spinneret and grounding the electrode such that an electric field is generated between the spinneret and the electrode of sufficient strength to impart an electrical charge on the polymer as it issues from the spinning nozzle.
