    Abstract: A process for preparation of a tufted polyamide-type fiber carpet is provided. A primary backing tufted with yarn comprised of at least 85% by weight of fibers selected from the group nylon fibers, wool fibers, and blends thereof is provided. A molten polymer adhesive is provided on the back side of the tufted primary backing, the polymer adhesive consisting of at least 85% by weight of one or more ethylene copolymers each comprised of 50 to 95 weight % of ethylene, and 5-50 weight % of at least one comonomer selected from the group of esters and carboxylic acids. The tufted primary backing and the molten polymer adhesive layer are compressed under a moving belt that applies a pressure of at least 1 N/cm2 for a period of at least 5 seconds during which time the polymer adhesive remains in a molten state. The molten polymer adhesive then cooled to a temperature below the melting point of said molten adhesive. A secondary backing may be placed over the molten polymer adhesive on the back of the primary backing.

    Abstract: An improved cushioned carpet fabric is provided. The cushioned carpet comprises a primary carpet having a primary base and a plurality of pile-forming yarns projecting outwardly from one side. A layer of reinforcement material is bonded to the primary base on the side opposite the pile forming yarns. The reinforcement layer is adjacent to and embedded in, a cushion layer of a polymer such as a polyurethane. There is preferably no additional adhesive between the cushion layer and the layer of reinforcement material since the primary carpet fabric is mated in-situ to the polyurethane-forming composition without preheating the polyurethane-forming composition. An apparatus and process for forming the cushioned carpet fabric of the present invention are also provided.

    Abstract translation: 提供改进的缓冲地毯织物。 缓冲地毯包括具有主底座的主地毯和从一侧向外突出的多个绒头成形纱。 一层增强材料在与绒头成形纱线相对的一侧上结合到主底座上。 加强层与诸如聚氨酯的聚合物的缓冲层相邻并嵌入其中。 优选地,在缓冲层和增强材料层之间不存在另外的粘合剂,因为主地毯织物在原位配合到形成聚氨酯的组合物而不预热形成聚氨酯的组合物。 还提供了用于形成本发明的缓冲地毯织物的装置和方法。
