  • 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: 6016648
    Abstract: Cut-resistant yarn suitable for machine knitting and machine-knitted protective articles of apparel, more specifically flexible gloves, at least in part made from such a yarn and also such gloves having a slip-resistant coating, preferably polyurethane, applied in a predetermined pattern to the outside surface of the gloves. The yarn utilizes a core of synthetic fibers held in a bundle by two initial wraps of low denier synthetic material having widely spaced turns or by a plastic coating on, or by a plastic matrix for, the fibers. One or more strands of metal wire or glass fiber are disposed about the core. The initial wraps or plastic that bundle the core create a uniform, cylindrical shape to the multi-filament fiber core that is believed to increase cut-resistance and that promotes uniformity in yarn diameter as subsequent wraps are applied, and prevent sharp bends in the wire or glass fibers disposed about the core. Additional wraps cover the wire or glass fiber.

  • Patent number: 5822791
    Abstract: The present invention provides a protective material comprising a base layer comprising cut resistant yarn, an intermediate layer comprising natural fiber and an outer layer comprising a flexible, elastomeric material impervious to liquid. The intermediate layer is bonded to the elastomeric material, while the cut resistant yarn in the base layer remains substantially free of encapsulation by the elastomeric material. The intermediate layer is joined to said base layer at one or more locations, preferably by selective strike through of limited amounts of the elastomeric material to encapsulate yarn in the base layer.

  • Patent number: 5809861
    Abstract: A cut-resistant braided yarn and apparel knit from the yarn; the braided yarn may be constructed as a simple hollow braid, but preferably comprises a core and a covering braided on the core; the braid or the braided covering on the core of the yarn comprises three or more strands of fiber selected from high and normal-strength fibers; the core comprises a high-strength fiber core-strand and may include a stainless steel wire core-strand; the denier and number of braiding strands is such that the final diameter of the yarn does not exceed about 0.035" (thirty five thousandths of an inch).

  • Patent number: 5745919
    Abstract: A protective glove comprising a cut-resistant glove and a grip enhancing sheath affixed to the cut-resistant glove. The sheath is preferably made of leather and is symmetrical providing a gripping surface that overlies substantially similar portions of a front and back side of the cut-resistant glove such that the protective glove is adapted for both right and left handed use. In one embodiment of the protective glove, the sheath is configured to overlie the thumb, index and middle finger stalls of the cut-resistant glove as well as a portion of the palm area of the glove. In a second embodiment of the protective glove, the sheath is configured to overlie the thumb and index finger stalls of the cut-resistant glove as well as a portion of the palm area of the glove.
