  • Static dissipative nonwoven textile material
    Patent number: 5324579
    Abstract: A nonwoven textile material useful in dissipating static electric charges containing an electrically conductive polytetrafluoroethylene fiber. An amount of a synthetic fiber may be intermixed with the electrically conductive polytetrafluoroethylene fiber to produce the static dissipative textile material. The nonwoven static dissipative textile material may combine with a porous polymeric membrane to form nonwoven fabric laminate.The nonwoven textile material is useful as a filtration media and may be fabricated into a filter bag.
    Type: Grant
    Filed: January 19, 1993
    Date of Patent: June 28, 1994
    Assignee: W. L. Gore & Associates, Inc.
    Inventors: Robert Sassa, Richard Winkelmayer, Jr.
  • Chemically protective laminate
    Patent number: 5264276
    Abstract: A chemically protective laminate comprising a thin thermoplastic barrier layer, having a consistent thickness, laminated between two porous polymeric membrane layers. The porous polymeric membrane may be of porous polytetrafluoroethylene, preferably expanded porous polytetrafluoroethylene. The chemically protective laminate may be subsequently adhered to a backing to form a fabric laminate capable of being assembled into a chemically protective article.
