  • Patent number: 4704311
    Abstract: 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.

  • Patent number: 4045949
    Abstract: 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.
