ABSTRACT:
A process wherein freshly-spun, undrawn, nonconductive filaments are combined with one or more spin-oriented, conductive filaments having a nonconductive component made from a major portion of nonconductive, fiber-forming polymeric material and a minor amount of polystyrene, the combined fibers being drawn and co-bulked to produce an anti-static yarn. The conductive filaments used in this process have higher elongations to break, and carpets tufted from the yarns of the process show improved anti-static properties.
