ABSTRACT:
A process for producing a conductive supported yarn includes melt spinning non-conductive nylon filaments into a first set of filaments, separating at least one of the filaments from the freshly spun first set into a second set of filaments, providing the second set of filaments to a suffusion coating process so that the suffusion coated second set has a resistivity of between about 10.sup.6 and about 10.sup.9 .OMEGA./cm, and then recombining the first set and the second set to form a supported yarn.
