  • Patent number: 9548596
    Abstract: A textile sleeve for routing and protecting elongate members and method of construction thereof is provided. The textile sleeve has an elongate textile wall constructed from interlaced yarn. An emulsion of acrylic binder and water-based silicon resin is applied to coat the interlaced yarn, with the acrylic binder providing resistance to end fray of the textile sleeve at temperatures below 150° C., and the silicone resin providing resistance to end fray between about 150-500° C.

  • Patent number: 9336924
    Abstract: A self-wrapping, textile sleeve for routing and protecting elongate members from exposure to abrasion, thermal and other environmental conditions and method on construction thereof. The sleeve has an elongate wall constructed from interlaced yarns having interstices between adjacent yarns. At least one of the yarns is heat formed at one temperature to form the wall as a self-wrapping wall curling about a longitudinal axis of the sleeve. The wall has an inner surface providing a generally tubular cavity in which the elongate members are received. The wall also has an outer surface with a cured layer thereon. The cured layer is cured at the one temperature at which the yarns are heat formed into their self-wrapping configuration, wherein the cured layer fills the interstices between adjunct yarns to form an impervious layer on the wall.

  • Patent number: 8528456
    Abstract: A textile sleeve and method of construction thereof is provided. The textile sleeve has a water-based, impervious coating for protecting elongate members contained within the sleeve. The sleeve has a flexible, tubular wall of tightly braided yarns with a coating applied thereto to render the wall impervious to fluid. The coating is a water-based coating applied as two distinct, first and second layers. The first, underlying layer includes a dielectric enhancing additive and a thickening agent to enhance the impermeability of the wall. The second, outer layer contains a similar formulation as the underlying first layer, however, it is free of the thickening agent.

  • Publication number: 20120168061
    Abstract: A sleeve bearing assembly and method of construction therefor includes a woven inner portion bonded to an injection molded elastic outer portion. The inner portion includes a first yarn of lubricious yarn material and a second yarn of material that is different than the first yarn. The first yarn substantially provides an inner bearing surface and the second yarn substantially provides an outer surface that is bonded to the outer portion. The first and second yarns are woven together so that the first yarn is woven in one of a weft direction corresponding to a circumferential direction of the journal bearing surface or a warp direction corresponding to an axial direction of the journal bearing surface to substantially provide the bearing surface and the second yarn is woven in a direction different than the first yarn to substantially provide the outer surface bonded to the outer portion.

  • Publication number: 20120148772
    Abstract: A coated textile sleeve for routing and protecting elongate members, combination thereof, and method of construction is provided. The textile sleeve has an elongate knit wall constructed from weft knit yarns. The knit wall has an inner surface providing a generally tubular cavity in which the elongate members are received and protected. The inner surface is formed, at least in part, by laid-in yarn to provide a soft, non-abrasive surface for dampening contact with the elongate members being protected to facilitate absorbing vibration, which in turn, reduces the frictional wear of the elongate members being protected. Further, the knit wall has an outer surface with a flexible, impervious elastomeric coating thereon. The elastomeric coating allows the knit wall to substantially retain its flexibility as knit, provides enhanced protection against the ingress of fluid and other contaminants, and providing added dampening to absorb vibration.
