Abstract
The present invention relates to abrasion resistance of bowstring fibers with a coating containing Polytetrafluoroethylene (PTFE) particles to increases string life. The claimed coating lowers the coefficient of friction of the bowstring reducing internal yarn on yarn abrasion, external abrasion and increases longevity.
