Abstract

Continuous processing methods are used for making absorbable polymeric non-wovens, with anisotropic properties, improved mechanical properties and without substantial loss of polymer molecular weight during processing. The method includes producing dry spun-non wovens from a polymer, and collecting the fibers using a rotating collector plate, preferably a rotating cylinder, to collect the non-woven instead of a fiberglass stationary collector plate. The non-wovens can be used for a variety of purposes including fabrication of medical devices.
