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.
