Abstract

A dispersion spun polytetrafluoroethylene fiber exhibiting improved elongation prior to fiber break and increased thermal stability, the fiber prepared by forming a spin mix containing a dispersion of poly(tetrafluoroethylene) particles, forming an intermediate fluoropolymer fiber structure from the spin mix, sintering the intermediate fluoropolymer fiber structure and forming a continuous fluoropolymer filament yarn, drawing the continuous fluoropolymer filament yarn, and thereafter heat setting the continuous fluoropolymer filament yarn.
