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.
Claims24
A fiber spinning process comprising:
- providing a polymer solution, which comprises at least one weakly interacting polymer having a dielectric constant less than about 3 dissolved in at least one weakly interacting solvent having a dielectric constant less than about 3, to a spinneret;
- issuing the polymer solution in combination with a blowing gas in a direction away 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.
