  • Patent number: 11313059
    Abstract: A self-wrapping protective textile sleeve and method of construction is provided. The sleeve includes a braided, tubular wall having opposite free edges extending lengthwise between opposite ends. The wall has a first state with a decreased length, increased cross-sectional area and a second state with an increased length, decreased cross-sectional area, as viewed in cross-section taken generally transversely to a central longitudinal axis. The wall further includes braided, heat-set yarns imparting a bias on the wall, wherein the bias causes the wall to self-wrap into a tubular configuration and to remain substantially in the first and second states absent some externally applied force.

  • Patent number: 11180872
    Abstract: A woven sleeve for routing and protecting an elongate member and method of construction thereof are provided. The sleeve has a woven wall with a circumferentially continuous outer periphery extending along a central axis between opposite ends. Warp yarns extend generally parallel to the central axis and fill yarns extend generally transversely to the warp yarns. At least a portion of the wall has a plurality of layers in abutment with one another. At least one of the fill yarns is provided as a shrinkable yarn that provides the wall with an ability to remain in a first, diametrically enlarged assembly state to facilitate assembly of the sleeve about the elongate member, whereupon the wall can be radially constricted to a second, diametrically constricted assembled state to maintain the sleeve in the desired location, while also minimizing the outer circumference to facilitate use of the sleeve in tight spaces.

  • Patent number: 10982355
    Abstract: A knit sleeve for providing thermal protection about an elongate member contained therein and method of construction thereof is provided. The sleeve includes a knit inner wall with opposite edges extending lengthwise between opposite ends and a circumferentially continuous tubular outer wall knit integrally with the inner wall. The outer wall bounds a central cavity that extends lengthwise along a central axis between open opposite ends of the outer wall. The opposite edges of the inner wall are substantially parallel to the central axis and are wrappable toward one another to form the inner wall as being tubular. The circumferentially continuous tubular outer wall is configured to be everted about the wrapped inner wall to circumferentially surround and protect the inner wall from abrasion and provide the sleeve with a dual layer wall.

  • Patent number: 10711378
    Abstract: A protective textile sleeve and method of construction thereof is provided. The sleeve has a knit, tubular wall extending lengthwise along a central longitudinal axis between opposite ends. The knit wall has a first state with a decreased length, increased cross-sectional area, as viewed in cross-section taken generally transversely to the central longitudinal axis, and a second state with an increased length, decreased cross-sectional area, as viewed in cross-section taken generally transversely to the central longitudinal axis. The wall includes knit, heat-set yarns imparting a bias on the wall, wherein the bias causes the wall to remain substantially in the first and second states absent an externally applied force.
