Abstract
A fiber spinning process which provides an uncharged, electrically conductive polymer-containing liquid stream, issues said liquid stream in combination with a forwarding gas in a direction from at least one spinning nozzle in said spinneret, passes said liquid stream through an ion flow formed by corona discharge to impart electrical charge to the liquid stream, forms fine polymer fibers of said polymer and collects said fine polymer fibers.
