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.

Antistatic fibers and methods for making the same

An improved fibrous polyacrylonitrile mixture for use in friction products enables the production of low resiliency preforms by mixing an additive with a polyacrylonitrile wet gel. The additive is incorporated into the fiber in extremely large amounts. The additive is a member selected from the group consisting of:

Fibrous polyacrylonitrile reinforcing mixture for friction product

This process for making antistatic filaments utilizes a specific mixture of compounds in order to suffuse electrically conductive particles into a filamentary polymeric substrate by forwarding the substrate through a grooved roll-type mix applicator. The mixture comprises a dispersion of the electrically conductive particles in liquid solvent which is a mixture of formic acid and a member selected from the group consisting of an amide, a carboxylic acid other than formic acid, an alcohol, an ester, a ketone, an ether, and a hydrocarbon. The process provides advantages over the prior art in permitting the use of high processing speeds, enabling easy stringup, and allowing the use of knotty and/or slubby filamentary substrates.
