  • Patent number: 11686022
    Abstract: A wrappable, corrugated woven sleeve and method of construction thereof is provided. The sleeve includes a wall having opposite edges wrapped about a central axis into overlapping relation with one another. The wall has a plurality of layers overlying one another. Each layer includes warp yarns extending generally parallel to the central axis woven with fill yarns extending generally transversely to the warp yarns. Each layer includes a plurality of annular first bands and a plurality of annular second bands alternating with one another along the length of the wall. The first bands of each layer include monofilament weft yarn and multifilament weft yarn and the second bands of each layer include only one of monofilament weft yarn or multifilament weft yarn. The first bands overlie one another to form peaks and the second bands B overlie one another to form valleys, such that the wall has a corrugated contour.

  • Patent number: 11332859
    Abstract: A textile sleeve for routing and protecting elongate members and method of construction thereof is provided. The sleeve includes an elongate, braided wall having a circumferentially continuous, tubular outer periphery extending along a central axis between opposite open ends. The wall includes shrinkable yarns and non-shrinkable yarns. The shrinkable yarn provides the wall with an ability to be radially contracted from a first, diametrically enlarged assembly state to a second, diametrically shrunken state.

  • 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.
