  • Publication number: 20160309626
    Abstract: A wrappable textile sleeve for protecting a conductive elongate member against at least one of EMI, RFI or ESD and method of construction thereof is provided. The sleeve includes a plurality of warp filaments and at least one weft filament woven with one another to form a woven substrate. The woven substrate has opposite sides extending lengthwise between opposite ends. The opposite sides are wrappable about a central longitudinal axis into overlapping relation with one another to circumferentially enclose the elongate member within a cavity of the sleeve. At least some of the warp filaments are provided as generally flat, thin conductive filaments shield the conductive elongate member against the effects of EMI, RFI and/or ESD.

  • Patent number: 9416469
    Abstract: A woven sleeve and method of construction are provided. The sleeve has a flexible, abrasion resistant, self-curling elongate wall constructed from woven monofilament and/or multifilament yarns. The wall has opposite edges extending generally parallel to a central axis of the sleeve, wherein the opposite edges overlap one another. The wall is woven with warp yarns that extend generally parallel to the central axis of the sleeve and fill yarns that extend circumferentially about the sleeve, generally transversely to the central axis. The warp yarns are bundled into individual, discrete groups, with each group including a plurality of yarns in side-by-side relation with one another, wherein each of the yarns within the same discrete group is interlaced over the same side of a common fill yarn.

  • Publication number: 20160016376
    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.

  • Publication number: 20150233029
    Abstract: A warp knit textile sleeve is provided. The sleeve has an elongate, wrappable wall extending along a longitudinal axis between opposite ends. The wall has opposite free edges extending lengthwise along the longitudinal axis between the opposite ends. The wall is knit from at least one warp yarn extending lengthwise between the opposite ends and a plurality of weft yarns extending circumferentially between the opposite free edges. The weft yarns form a plurality of discrete, annular bands alternating in adjacent relation along the longitudinal axis. The weft yarn of one of the adjacent bands has a first diameter and the weft yarn of the other of the adjacent bands has a second diameter, wherein the first diameter is less than the second diameter.

  • Publication number: 20150093556
    Abstract: A wrappable textile sleeve and method of reducing cracking in a foil layer of a wrappable textile sleeve are provided. The sleeve includes an elongate wall extending along a longitudinal axis between opposite ends with lengthwise extending edges extending along the longitudinal axis between the opposite ends. The wall includes a textile layer, a polymeric film layer fixed to the inner textile layer and a metal foil layer fixed to the polymeric film layer. The polymeric film layer has a first thickness and the metal foil layer has a second thickness, wherein the second thickness is greater than the first thickness.

  • Publication number: 20140273698
    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.

  • Publication number: 20140220846
    Abstract: A wrappable textile sleeve and method of construction thereof is provided. The wrappable textile sleeve includes an elongate wall extending along a longitudinal axis between opposite ends with lengthwise extending edges extending parallel or substantially parallel with the longitudinal axis between the opposite ends. The wall is woven from lengthwise extending warp yarns and circumferentially extending weft yarns. The weft yarns form a plurality of discrete annular bands, with adjacent bands having weft yarns of different diameters to provide the wall with discrete enhanced hoop strength regions and with discrete enhanced flexibility regions, where the enhanced hoop strength and enhanced flexibility regions alternate in adjacent relation with one another.
