Abstract
A corrugated protective textile sleeve has a flexible, tubular wall of woven warp yarns, extending lengthwise along a longitudinal axis between opposite ends of the wall, and weft yarns, extending generally transversely to the warp yarns. At least some of the weft yarns are activatable weft yarn to shrink in length and at least some the weft yarns, adjacent the activatable weft yarn, are substantially non-activatable weft yarn. The substantially non-activatable weft yarn form crests, having a first diameter, spaced axially from one another and the activatable weft yarns, upon being activated and shrunken, form valleys, having a second diameter less than the first diameter, with at least some of the valleys extending between the crests to form the wall having a corrugated contour.
