  • Patent number: 10272640
    Abstract: Low porosity fibrous materials, articles formed therefrom and processes for their formation. Multiple plies of high tenacity, multifilament elongate bodies are optionally stitched together and pressed as a set without being laminated, adhered or thermally fused to each other. Pressing spreads the component filaments of the elongate bodies, forcing the filaments to occupy spaces between adjacent fibers and thereby reducing porosity of the complete multi-ply material.

  • Patent number: 10059081
    Abstract: The present invention is directed to fibers, nonwoven fabrics, and nonwoven laminates comprising a blend of at least one impact copolymer and at least one propylene-based elastomer. The blends comprise from about 45 to about 85 wt % of an impact copolymer, where the impact copolymer comprises a blend of a propylene homopolymer and a copolymer comprising from about 20 to about 80 wt % propylene-derived units and from about 20 to about 80 wt % ethylene-derived units. The blends further comprise from about 15 to about 55 wt % of a propylene-based elastomer, where the propylene-based elastomer comprises from about 5 to about 25 wt % units derived from one or more C2 or C4-C12 alpha-olefins and has a triad tacticity greater than about 90% and a heat of fusion less than about 75 J/g.

  • Patent number: 9944493
    Abstract: A suspension and transmission device for use with an elevator system comprises one or more strips that provide load carrying, transmission or traction, and load carrying redundancy or safety functions for the elevator system. In one version a single strip comprised of polymer and composite materials provides these functions. In another version multiple strips comprised of polymer and composite materials provide these functions. In another version, a strip comprises a hollow interior portion. In another version one or more strips incorporate materials that can be detected when using the strip to monitor the condition of the one or more strips.
