  • Rope for heavy lifting applications
    Patent number: 6945153
    Abstract: A large diameter rope having improved fatigue life on a sheave, pulley, or drum is disclosed. This rope includes a blend of HMPE filaments and liquid crystal polymer filaments selected from the group of lyotropic polymer filaments and thermotropic polymer filaments. The rope may be constructed as a braided rope, a wire-lay rope, or a parallel core rope.
    Type: Grant

  • Tufted fabrics
    Patent number: 5626912
    Abstract: The present invention relates to a tufted fabric and a method of manufacturing the same. The tufted fabric generally comprises a primary backing and tufts mounted in the primary backing to form a fabric with a faceside having piles and a backside having loops. A thermoplastic polymer adhesive, which bonds the tufts to the primary backing, is formed by applying a reactive mixture comprising a polymerizable monomer to the backside of the tufted fabric and in-situ polymerizing the monomers to form the thermoplastic polymer adhesive. The process is particularly advantageous for the manufacture of recyclable tufted fabrics in which the adhesive polymer and tufts are formed from substantially the same polymer. The tufted fabric can be used in articles, such as, for example carpets, rugs and upholstery.
