  • Wear polytetrafluoroethylene (PTFE) fiber and method of making same
    Patent number: 10106916
    Abstract: A fluoropolymer fiber exhibiting improved wear properties prepared from a blend of fluoropolymer particles and aluminum oxide particles. The concentration of aluminum oxide particles in the blend ranges from between about 0.1% to about 5%, with a specific concentration of 0.1% to 1.0%. The fluoropolymer fibers may be dispersion spun, melt spun or paste extruded.
    Type: Grant
    Filed: December 22, 2015
    Date of Patent: October 23, 2018
    Assignee: TORAY FLUOROFIBERS (AMERICA), INC.
    Inventors: Chester Darryl Moon, Arthur Russell Nelson, Trevor Guldstrand, Matt Hutto
  • Wear Polytetrafluoroethylene (PTFE) Fiber and Method of Making Same
    Publication number: 20160326336
    Abstract: A dispersion spun fluoropolymer fiber prepared from non-melt-processible polytetrafluoroethylene particles and aluminum oxide particles. The concentration of Al2O3 in the aqueous dispersion may range from between about 0.1% to about 5%, with specific concentration of 0.1%, 1.0. The aqueous dispersion is mixed with an aqueous matrix polymer solution containing a matrix polymer and then extruded into a coagulation bath containing a concentration of ions which coagulate the matrix polymer to form an intermediate fiber structure which carries ionic species. The intermediate fiber structure is sintered to decompose the matrix polymer and coalesce the polytetrafluoroethylene particles and the Al2O3 particles into a blended fiber. The resulting, blended fluoropolymer fiber exhibits improved properties relative to 100% dispersion spun polytetrafluoroethylene fibers.
