Self-wrapping, braided textile sleeve with self-sustaining expanded and contracted states and method of construction thereof
First Claim
1. A self-wrapping protective textile sleeve, comprising:
- a braided, tubular wall having opposite free edges extending lengthwise between opposite ends; and
said wall having a first state with a decreased length, increased cross-sectional area, as viewed in cross-section taken generally transversely to a central longitudinal axis extending between said opposite ends, and a second state with an increased length, decreased cross-sectional area, as viewed in cross-section taken generally transversely to said central longitudinal axis, and further including braided, heat-set yarns imparting a bias on said wall, said bias causing said wall to remain in said first and second states absent some externally applied force and bringing said opposite free edges into overlapped relation with one another.

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.

13. A method of constructing a self-wrapping textile sleeve, comprising:
-
braiding a plurality of yarns with one another to form a wall extending lengthwise along a central longitudinal axis between opposite ends with at least some of said yarns being provided as heat-settable yarns, said wall being moveable between a decreased length, increased cross-sectional area first state and an increased length, decreased cross-sectional area second state; forming said wall having opposite free edges extending lengthwise between said opposite ends; and wrapping said opposite free edges toward one another and heat-setting said heat-settable yarns with said wall being in one of said first state and second state to form heat-set yarns that impart a bias on said wall, said bias causing said wall to self-wrap about the central longitudinal axis into a tubular configuration and causing said wall to remain in each of said first and second states absent an externally applied axial force causing said wall to be moved to the other of said first or second states. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
