    Abstract: Lamination of a tufted, primary carpet backing to a secondary backing is conducted using a composite hot melt adhesive in sheet form. The composite adhesive overcomes the unfavorable temperature-viscosity gradient within the carpet structure during the lamination process, yielding tufted pile carpets with good tuft encapsulation, tuft bind strength and delamination strength. Also disclosed are hot melt adhesive compositions suitable for use in sheet form in such a process.

    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: Multicolored pile materials, and particularly pile carpets, comprising a fabricated backing and a fabricated pile face having: (1) upper pile face portions which have a predetermined color; and (2) lower pile face portions which have a color which is different and darker than the predetermined color of the upper pile face portions, whereby unusual multicolored effects are obtained; and, more specifically, multicolored pile fabrics, and particularly pile carpets, comprising a fabricated backing and a fabricated pile face having: (1) upper pile face portions which are substantially white in color; and (2) lower pile face portions which have a color which is different and darker than white, whereby unusual multicolored, frosted effects are obtained. Processes for making such multicolored or frosted pile materials are also included.
