Abstract
Electrostatic spinning method for producing tubular fibrous structures from fiberizable material wherein the fiberizable material is collected on an electrostatically charged mandrel wherein the fiberizable material takes different paths from the source to the mandrel to produce a structure of smaller diameter fibers randomly oriented, larger diameter fibers and/or bundles of fibers circumferentially oriented and elongated voids circumferentially oriented.
