    摘要: Expanded polytetrafluoroethylene (ePTFE) monofilament fibers and woven fabrics formed from the ePTFE fillers are provided, The ePTFE fibers have a substantially rectangular configuration, a density less than about 1.0 glee, and an aspect ratio greater than 15. Additionally, the ePTFE fibers are microporous and have a node and fibril structure. The ePTFE fiber may be woven into a fabric without first twisting the fiber. A polymer membrane and/or a textile may be laminated to the woven fabric to produce a laminated article. The ePTFE woven fabric simultaneously possesses high moisture vapor transmission (highly breathable) and high water entry pressure (water resistant). The woven fabric is quiet, soft, and drapable, making it especially suitable for use in garments, gloves and footwear applications. Treatments may be provided to the surface of the ePTFE fiber and/or the woven fabric to impart one or more desired functionality, such as, for example, oleophobicity).

    摘要: 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.
