  • the wall 12 can be constructed having any suitable size, including length and diameter.
  • the wall 12 includes an inner, interlaced textile layer 23 having an inner surface 15 and an opposite outer surface 17 extending lengthwise about a longitudinal central axis 20 between opposite ends 19, 21, with inner surface 15 bounding a cavity 22 sized for receipt of the elongate member 14 therein.
  • the wrappable sleeve 10 has opposite edges 16, 18 that extend parallel or generally parallel (intended to mean that to the naked eye, a person possessing ordinary skill in the art (POSA) would view the relationship to be parallel, though it may not be truly parallel) to the longitudinal central axis 20, wherein the opposite edges 16, 18 are wrappable into overlapping relation with one another in "cigarette wrapped” fashion to fully enclose the elongate member 14 within the central cavity 22.
  • the inner, interlaced textile layer 23 is formed of yams 24 interlaced with one another in one of a woven (a portion of the entire woven textile layer 23 is shown in Figure 2A, with the remaining woven portion not shown being the same) or braided (a portion of the entire braided textile layer 23 is shown in Figure 2B, with the remaining braided portion not shown being the same) fashion, wherein at least some of the yams 24 include multifilaments 24a (a multifilament is a term well known to a POSA, known to be a single yam including multiple filaments intertwined with one another) resistant to heat and/or monofilaments 24b (a monofilament is a term well known to a POSA, known to be a single, solid filament of material) resistant to heat.

  • the silicone-based layer 26 is a fluid impervious coating, thereby being impervious to water, fuel (e.g. kerosene), oil, and the like, to render the wall 12 fluid impervious as well as fluid repellant. As such, fluid is prevented from being absorbed by the interlaced layer 23, thus, preventing water, fuel and the like from compromising the ability of the sleeve 10 to provide the desired levels of protection.
  • the silicone-based layer 26 can be provided as a high density silicon to achieve increased mechanical, electrical and impact protection. Further yet, the silicone-based layer 26 can include at least one or both of a flame retardant and a heat stabilizer, and can be provided being flame resistant and selfextinguishing if exposed to flame.
  • the silicone-based layer 26 can be provided having a thickness between about 0.1-3.0mm, by way of example and without limitation, thereby contributing to the wall 12 having a radially narrow, low profile, thereby enhancing the flexibility and ability to be routed in relatively small, tight spaces.

  • the silicone-based layer 26a penetrates through interstices of the textile layer 23, wherein the silicone-based layer 26a can extend flush with or radially inwardly from the inner surface 15 of the textile layer 23, thereby providing a soft, generally smooth innermost surface 26b of the silicone-based layer material for abutment with an outer surface of the elongate member 14.
  • the outer surface of the elongate member 14 is protected against abrasion by being contacted by the soft, elastic material 26b of the silicone-based layer 26a.
  • the silicone-based layer 26 can be molded directly to the outer surface 17 of the textile layer 23, whereupon liquid material of the silicone-based layer 26a can flow though the openings radially inwardly of the textile layer inner surface 15.
  • the textile layer 23 can be formed via a loose weave (Figure 2A) or loose braid ( Figure 2B), thereby providing increased size openings 30 through the woven or braided textile layer 23.

  • EMI electromagnetic interference
  • the opposite edges 16, 18 overlapped with one another opposite edges of the silicone-based layer 26a can be brought into abutting relation with one another, forming a butt-type joint 32, thereby providing circumferentially continuous protection to the elongate member(s) 14.

Abstract

Un manchon textile pour acheminer et protéger un élément allongé présente une paroi enroulable comprenant une couche textile ayant une surface interne et une surface externe opposée s'étendant dans le sens de la longueur entre des extrémités opposées et dans le sens de la largeur entre des bords opposés. Les bords opposés sont configurés pour être enroulés autour d'un axe longitudinal central pour délimiter une cavité centrale s'étendant dans le sens de la longueur le long de l'axe longitudinal central entre les extrémités opposées. La couche textile est formée de fils entrelacés les uns avec les autres, au moins certains des fils comprenant un ou plusieurs fils métalliques. Une couche à base de silicone est disposée autour de la surface externe de la couche textile pour conférer une résistance à la chaleur, une protection diélectrique et une résistance aux chocs améliorées.
