    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: A felting of synthetic fibers having an embossed pattern that forms depressions in at least one surface of the felting is disclosed. The surface of the felting with depressions contains, in at least the area of the depressions, a layer of small hollow spheres that are bonded to one another and to the felting by means of a binding agent. The layer of hollow spheres fills up, at least partially, the depressions in the surface of the felting produced by embossing. This reinforces and strengthens the thinner areas of felting in the vicinity of these depressions. When the reinforced felting is applied to a shoe upper, for example, the resulting upper has improved stiffness and strength. Furthermore, the excessive penetration of adhesive into the felting, which can cause a spotty or uneven appearance of the reinforced upper, is prevented. Resistance to splitting and separating is likewise improved.

    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.
