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.

Braided textile sleeve with integrated opening and self-sustaining expanded and contracted states and method of construction thereof

A protective textile sleeve and method of construction thereof are provided. The sleeve has a tubular wall of braided yarns extending lengthwise along a central longitudinal axis between opposite ends. At least some of the braided yarns including heat-set yarns, and the wall has a plurality of annular first regions forming generally convex ridges and a plurality of annular second regions forming generally concave valleys. The first regions alternate with the second regions along the central longitudinal axis. The first regions include a plurality of twisted yarns forming a plurality of closed loops, wherein at least some of the braided yarns pass through at least some of the closed loops within the first regions to enhance the radial stiffness and resistance of the wall to kinking.

Braided textile sleeve with axially collapsible, anti-kinking feature and method of construction thereof

A fabric sleeve for protecting elongate members against at least one of EMI, RFI or ESD and method of construction thereof is provided. The sleeve includes a wall extending along a longitudinal axis between opposite ends. The wall is formed from a plurality of filaments interlaced with one another, with at least one of the filaments being provided as a continuous strand of conductive wire and at least some of the filaments being provided as heat-fusible nonconductive filaments. The heat-fusible nonconductive filaments abut the continuous strand of conductive wire at a plurality of bond joints. The continuous strand of conductive wire is at least partially embedded in bonded, fixed attachment with the heat-fusible nonconductive filaments at the bond joints.

Protective sleeve with bonded wire filaments and methods of construction thereof

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.

Enhanced braided sleeve and method of construction thereof

A hybrid yarn filament and sleeve constructed therefrom for protecting elongate members against at least one of EMI, RFI or ESD is provided, along with methods of constructing the hybrid yarn filament and sleeves. The hybrid yarn filament has a nonconductive filament and at least one conductive wire filament overlying an outer surface of the nonconductive filament. The hybrid yarn filament is arranged in electrical communication with itself or other hybrid yarn filaments during construction of the sleeve to provide uniform shielding against EMI, RFI, and and/or ESD.
