Abstract
A wrappable textile sleeve and method of construction thereof is provided. The textile sleeve includes an elongate wall extending along a longitudinal axis between opposite ends with lengthwise extending edges extending along the longitudinal axis between the opposite ends. The wall is woven from lengthwise extending warp yarns and circumferentially extending weft yarns with at least some of the weft yarns being heat-set to impart a self curling bias on the wall to bring the edges into overlapping relation with one another. Further, the weft yarns form a plurality of discrete annular bands that extend circumferentially about the longitudinal axis with adjacent bands having different picks-per-inch from one another to provide the sleeve with enhance regions of flexibility, self-curling bias and hoop strength.
