  • Patent number: 6318504
    Abstract: A synthetic fiber rope having load-bearing aramide fiber strands laid together in parallel in concentric layers of strands and an intersheath with sheath surfaces adapted to the external contours of the adjacent layers of strands. By positively bonding the inner and outer layers of strands a higher torsional rigidity is achieved as well as a rope structure of the stranded rope which is less susceptible to twisting. Furthermore, the elastic intersheath between the layers of stands serves to protect the strands against abrasion and assists in transmitting torque within the rope over a large area.

  • Patent number: 6266951
    Abstract: A knittable, cut-resistant yarn for use in protective wear, such as gloves, arm protectors, aprons, or the like, including a core with at least one strand of flexible, stainless steel wire having a diameter of about 0.002 inches and at least one strand of an anti-microbial treated fiber. A first wrap is wound in one direction about the core and is a polyester fiber having a denier in the range of 40-600 and a second wrap is wound in a second direction about the core which includes at least one strand of a polyester fiber having a denier in the range of 40-600. The anti-microbial treated fiber may be acetate-based, acryl-based or olefinic. The anti-microbial treated fiber contains an anti-microbial agent, such as Microban-B, where the active ingredient is 5 chlor-2-(2,4 dichlorophenoxy) phenol.

  • Patent number: 6260344
    Abstract: A knittable cut resistant yarn for use in protective wear, such as gloves, arm protectors, aprons, or the like, including a core with at least one strand of flexible material selected from the group consisting of stainless steel wire and poly-paraphenylene terephthalamide. The core is wrapped with at least one strand of an antimicrobial treated acrylic fiber. A first wrap is wound in one direction about the core having a denier in the range of about 75 to about 600. Each additional wrap is wound about the core in a different direction. The antimicrobial treated acrylic fiber contains the antimicrobial agent 5-chloro-2-(2,4-dichlorophenoxy)phenol.

  • Patent number: 6230524
    Abstract: A knit article having an edge portion subject to raveling with the article including plurality of knitting courses in said edge portion. Each of the edge portion knitting courses is knitted with a composite heat fusible yarn comprising a core including at least one low melt core strand and at least one cover strand wrapped around the core in a first direction. The cover strand is wrapped around the core at a rate suitable to partially cover the core while leaving exposed a sufficient amount of the core to facilitate a bond to an adjacent yarn strand in a knit structure upon application of heat to the core.

  • Patent number: 6216431
    Abstract: A composite yarn formed of melt-fusible thermoplastic fibers combined with selected other fibers and/or materials includes a containment barrier that encapsulates one or more core materials which may present a threat of contamination to workers and/or the environment. The composite yarn includes a core covered by an adhesive layer of thermoplastic material which forms a containment barrier, combined with one or more subsequent overlying layers of fibers wrapped or otherwise applied thereto using conventional yarn construction methods. In a preferred embodiment the core material is coated with a liquid adhesive, and preferably a polyester-based polyurethane which contains silicon grit, just prior to being wrapped with one or more layers of fibers which form the containment barrier. The cured and finished composite yarn is designed for knitting and weaving fabrics, or for otherwise forming cordage and non-woven products.

  • Patent number: 6116113
    Abstract: A composite link includes a fiberglass body. The body is formed by coating glass fibers with a liquid resin and winding the fibers around a plurality of end pieces or bushings. The end pieces have transition sections for smoothly changing the shape of the composite link and the path of the fibers. The fibers are wound in two layers, a first extending longitudinally of the body and the second transversely and around the first. A shield layer is placed over the fiberglass body.
