A conductive fiber is made by an electroless plating process which is used in conjunction with a wet spinning process. The polymer must be catalyzed before the wet gel is collapsed. The resulting filament has a conductive region which is at least partially coincident with the polymer structure.

Conductive fiber and method of making same

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.

Process for making electrically conductive textile filaments

A method and apparatus for blending a 'primary staple' with a 'secondary staple' wherein the weight ratio of the primary staple to the secondary staple is between 10,000:1 and 10:1 is disclosed. The secondary staple is continuously supplied to a blending machine (already working a primary staple) by drafting a textile roving. The drawn roving is then disintegrated into the secondary staple by an air flow amplifier. The air flow amplifier also supplies an air flow to transport the secondary staple to a blending machine, where it is blended into the primary staple.

Blending method using a roving disintegrator-dispenser

Static-dissipating fabric constructions especially suitable as upholstery material comprise a dielectric wear surface, which is a durable film or sheet of polymeric material such as polyvinyl chloride or polyurethane, and a conductive substratum securely bonded to the underside of the wear surface. The substratum has a surface resistance of 10.sup.9 ohms/square or less.

Static-dissipating fabrics

Finely divided, electrically conductive particles are uniformly suffused into a filamentary polymer substrate in an annular region located at the periphery of the filamentary polymer substrate and extending along the length thereof. The electrically conductive particles are employed in an amount sufficient to render the electrical resistance of the filamentary polymer substrate not more than about 10.sup.9 ohms/cm. The filamentary polymer substrate finds special utility in the fabrication of antistatic fabrics and floor coverings.

Electrically conductive textile fiber

The invention is an integral, electrically-conductive textile filament comprising from 2 to about 1000 electrically-conducting, longitudinally-directed strata of fiber-forming polymeric material, and one non-conducting stratum of the same polymeric material in coextensive union with each electrically-conducting stratum along the length of at least one of its major surfaces. Each electrically-conducting stratum of polymeric material has dispersed therein finely-divided particles of electrically-conductive carbon black. The electrical resistance of the integral filament is not more than about 10.sup.9 ohms/cm.
