Abstract

A process and materials made by the process which includes a bicomponent fiber, made of a nonconductive first component, including a first fiber-forming polymer selected from the group consisting of polyethylene terephthalate, nylon 6, nylon 6,6, cellulose, polypropylene cellulose acetate, polyacrylonitrile and copolymers of polyacrylonitrile; a conductive second component, including carbon particles and a second fiber-forming polymer selected from the group consisting of polyethylene terephthalate, nylon 6, nylon 6,6, cellulose, polypropylene cellulose acetate, polyacrylonitrile and copolymers of polyacrylonitrile; and a conductive third component, including a polymer selected from the group consisting of polypyrrole and polyaniline, said polymer formed in situ and being interspersed among at least a portion of the carbon particles of the second component.
