摘要 |
The present invention is an expanded polytetrafluoroethylene (PTFE) floss with improved handling properties. Unlike previous expanded PTFE flosses, the floss of the present invention employs a fiber of increased thickness so that the floss is maintained in an unfolded orientation. The improved processing steps of the present invention create a floss that has a number of improved properties, including more uniform dimensions along its length, improved compressibility and handling, and automatic visual indicati on of those segments of the floss that have been used.
