Abstract
A method and apparatus for generation of fine fibers via electro-spinning from a polymer solution is provided. The spray or spinning electrode is dipped in a polymer solution to maintain a polymer solution coating on the electrode for electrostatic spinning of fine fibers. A cover provides an evaporation barrier that reduces solvent loss. The drive unit may move the electrode around the cover to facilitate dipping of part of the electrode while exposing another part of the electrode for electro-spinning of fine fibers.
