IMPROVED ELECTROBLOWING WEB FORMATION PROCESS

摘要

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 and a resulting nanofiber web is collected on a collection means. The process includes applying a high voltage to the collection means and grounding the spinneret such that an electric field is generated between the spinneret and the collection means of sufficient strength to impart an electrical charge on the polymer as it issues from the spinning nozzle.
