  • Patent number: 5912062
    Abstract: The present invention provides compositions and processes wherein recycling of waste carpets and textiles is achieved by coating the individual yarn fibers with a low viscosity adhesive that is dispersed or dissolved in a suitable solvent to affect coverage of the fine fibers, and arranging the coated fibers in layers to affect the most desirable physical properties and then cured to provide a high modulus matrix for the coated fibers in the laminate structure. The fibers may be from unshredded or shredded waste carpets, shredded waste woven or non woven fabrics, fabric bits, and knitted fabrics. When the carpet is used in an as received condition, the face yarns, which may contain one or more components yarns, are coated and the carpets are arranged in a sandwich construction wherein the backings of the two carpets are placed back-to-back, e.g., (F-B-(B-F).sub.

  • Patent number: 5895695
    Abstract: The invention described herein pertains generally to a crosslinked plumbing tube which has at least one overmolded end (e.g. nose cone or nut) attached thereto. In one aspect of this invention, the tube is more rigid than the overmolded component while in another aspect of the invention, the tube is more flexible than the overmolded component. In either embodiment of this invention, the tube provides an all-plastic waterway for a contained liquid or gas to flow through. The degree of flexibility is controlled independently controlling the density of the tube polymer and the overmolding polymer. In one aspect of the invention, the tube and the overmolding polymer are both partially crosslinked to independent first degrees prior to the overmolding process. Subsequent to the overmolding process, the crosslinking is continued to a higher degree for both polymers.
