20230323573 · 2023-10-12 ·

A wrappable woven sleeve includes a wall having opposite edges extending lengthwise between opposite ends. The opposite edges are configured to be wrapped about a central longitudinal axis, whereupon the wall takes on a tubular configuration with an inner surface of the wall bounding an enclosed cavity sized for receipt of an elongate member to be protected therein and an outer surface of the wall facing radially outwardly from the central longitudinal axis. The wall is woven with warp filaments extending generally parallel to the central longitudinal axis and weft filaments extending generally transversely to the warp filaments. One or more of the warp filaments are wire to shield against passage of low frequency EMI. A foil layer is fixed to the outer and/or inner surfaces of the wall to shield against passage of high frequency EMI.

FLEXIBLE, ARC RESISTANT, FLUID REPELLANT, HIGH TEMPERATURE AND ABRASION RESISTANT, WRAPPABLE TEXTILE SLEEVE AND METHOD OF CONSTRUCTION THEREOF

A wrappable sleeve has a wall including an interlaced layer providing an inner surface and an opposite outer surface extending widthwise between opposite edges and extending lengthwise between opposite ends. The opposite edges are wrappable about a central longitudinal axis to bound the elongate member within a cavity bounded by the inner surface. The interlaced layer is formed of yarns interlaced with one another, wherein a least some of the yarns include multifilaments resistant to heat and monofilaments resistant to heat. The wall further includes a silicone-based coating adhered to the outer surface of the interlaced layer, and a closure member fixed along one of the opposite edges. The closure member has an adhesive surface configured to maintain the opposite edges of the wall in overlapping relation with one another.
