ABSTRACT:
The present invention is an expanded polytetrafluoroethylene (PTFE) fiber with improved handling properties. Unlike previous expanded PTFE fibers, the fiber of the present invention employs a fiber of increased thickness so that the fiber is maintained in an unfolded orientation. The improved processing steps of the present invention create a fiber that has a number of improved properties, including more uniform dimensions along its length, improved compressibility and handling, and when woven into a fabric, the fabric is more easily processed, is of higher quality, and is more uniform.
