    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.

    Abstract translation: 描述了由稳定的石油沥青,煤焦油沥青或至少部分碳化导电的合成纤维形成材料制成的连续长丝或短纤维纱线制成的导电丝束或纱线,例如聚丙烯腈,形成为 通过将丝束或纱线卷绕在心轴上,但优选通过将丝束或纱线编织成布,并将所形成的丝束或纱线热处理至碳化温度(450℃至约1500℃) C.)在其中设置线圈(非纺织品卷曲)以及其导电,并将卷绕结构结合到稀松布纱,稀松布毛衣,具有簇绒组件的复合材料以及结合到地毯纱中,以提供 对成品地毯的抗静电性能。
