  • Patent number: 10443166
    Abstract: A protective textile having at least one integrated opening and method of construction thereof is provided. The sleeve includes a braided, tubular wall extending lengthwise in relation to a central longitudinal axis 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 the central longitudinal axis. The wall further includes braided, 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 some externally applied force. The wall also includes at least one opening having a circumferentially continuous periphery bounding the opening, wherein the periphery is formed, at least in part, by braided yarns reversing direction from one S or Z helical direction to the opposite S or Z helical direction.

  • Patent number: 9394636
    Abstract: A braided protective sleeve and method of construction thereof is provided. The sleeve has a wall extending along a longitudinal axis of the sleeve. The wall includes a plurality of braided yarns forming inner and outer surfaces of the sleeve. The inner surface bounds an internal cavity and the outer surface is exposed to the surrounding environment. The yarns are braided with one another in a X/Y braid pattern with X and Y being different numerical values from one another. The numerical values of X and Y can be selected as desired to provide the sleeve with the enhanced physical performance characteristics desired. A plurality of yarns extending substantially parallel to the longitudinal axis can be interlaced with the braided yarns. The interlaced yarns can be exposed to the internal cavity and concealed from the environment; exposed to the environment and concealed from the internal cavity, or both.
