  • Patent number: 11834760
    Abstract: An end fray resistant textile sleeve includes an elongate wall having warp yarns extending generally parallel to a longitudinal central axis of the sleeve and fill yarns extending circumferentially about the sleeve. The warp yarns include at least two different types of yarns, with one of the types of warp yarns including activateable yarns and another of the types of yarns including non-activateable yarns. The activateable yarns can be provided as being activateable by at least one of heat, fluid and/or pressure, such that upon being activated, the yarns are caused to bond with the adjacent non-activateable warp yarns, as well as with the weft yarns with which they make contact. As such, the activateable yarns, upon being activated, become fixed with abutting warp yarns and weft yarns, thereby inhibiting end fray from resulting during a subsequent cold-cutting operation as well as in use.

  • Patent number: 11305508
    Abstract: A protective textile sleeve for routing and protecting elongate members against impact and method of constructed thereof are provided. The sleeve includes a plurality of yarns interlaced with one another, with the interlaced yarns forming an elongate, circumferentially continuous, tubular wall extending lengthwise along a longitudinal axis between opposite open ends. At least some of the plurality of yarns include tubular yarn having a central cavity extending along the length of the tubular yarn, thereby providing an impact resistant, dual layered wall to the tubular yarn. The sleeve can be constructed in a weaving, braiding or knitting process, wherein the tubular yarn can be interlaced as a woven yarn, braided yarn, or knit yarn, and further, the tubular yarn can be interlaced as an inserted yarn.

  • Publication number: 20190291383
    Abstract: A wrappable textile sleeve and method of construction thereof is provided. The sleeve includes a woven wall having opposite inner and outer edges extending in a lengthwise direction along a central longitudinal axis of the sleeve between opposite ends. The opposite inner and outer edges are wrappable into overlapping relation with one another to form an inner tubular cavity. The wall has an innermost woven layer and an outermost woven layer woven in attached relation with one another at one of the opposite inner and outer edges. A reflective layer is sandwiched between the innermost woven layer and the outermost woven layer, such that the outermost woven layer protects the underlying reflective layer against abrasion.

  • Patent number: 9816208
    Abstract: A self-wrapping textile sleeve that is abrasion, arc and water resistant and method of construction thereof is provided. The sleeve includes a wall having opposite edges extending in a lengthwise direction along a central longitudinal axis of the sleeve between opposite ends. The opposite edges overlap one another to form an inner tubular cavity. The wall has warp yarns extending in the lengthwise direction generally parallel to the central longitudinal axis and weft yarns extending generally transversely to the longitudinal axis between the opposite edges. The warp and weft yarns include expanded PTFE yarns, and the weft yarns further include heat-settable thermoplastic yarns. The heat-settable polymeric yarns impart a bias on the wall to bring the opposite edges into their overlapping relation.
