Abstract

A fiber spinning process comprising the steps of providing a polymer solution, which comprises at least one weakly interacting polymer dissolved in at least one weakly interacting solvent to a spinneret; issuing the polymer solution in combination with a blowing gas in a direction from at least one spinning nozzle in the spinneret and in the presence of an electric field; forming fibers and collecting the fibers on a collector.
