ABSTRACT:
There is described an electroconductive tow or yarn, made from continuous filaments or staple fibers yarns, prepared from stabilized petroleum pitch, coal tar pitch or a synthetic fiber forming material which on at least partial carbonization is electroconductive, for example, polyacrylonitrile, are formed into coil-like fibers or filaments by winding the tow or yarn on a mandrel, but preferably by knitting the tow or yarn into a cloth, and heat treating the so formed tow or yarn to a carbonizing temperature (450.degree. C. to about 1500.degree. C.) to set a coilure (a non-textile crimp) therein as well as electroconductance thereto, and incorporating the coilure structure into scrim yarns, scrim capcoats, composites with tuft-lock components as well as incorporation into the carpet yarns, to provide an anti-static property to the finished carpet.
