A protective textile sleeve and method of construction thereof is provided. The sleeve includes a circumferentially continuous wall extending lengthwise along a longitudinal axis between opposite ends. The wall has a first section formed from a non-heat-shrinkable, non-elastic yarn and a second section formed from one of a heat-shrinkable or elastic yarn. The first section extends lengthwise between the opposite ends and spans (X) degrees about the circumference of the wall between opposite lengthwise extending edges while in an unshrunken or stretch. The second section extends lengthwise between the opposite ends and spans (360-X) degrees about the circumference of the wall. The heat-shrikable or elastic yarn of the second section extends continuously as an uninterupted yarn between the opposite edges of the first section.

Circumferentially continuous and constrictable textile sleeve and method of construction thereof

A woven sleeve, sleeve assembly and methods of construction thereof are provided. The sleeve has a flexible, abrasion resistant, circumferentially closed and continuous elongate wall extending lengthwise along a central axis between opposite ends. The wall is woven with warp yarns extending generally parallel to the central axis and at least one heat-shrinkable weft yarn extending generally transversely to the warp yarns. The warp yarns provide the sleeve with coverage, abrasion resistance and flexibility and the weft yarn provides the ability to shrink the wall about an elongate member being protected within a cavity of the sleeve, as well as providing enhanced crush strength and abrasion resistance. At least one of the warp yarns and/or weft yarn includes at least one low melt, heat-fusible yarn served therewith to enhance resistance to end-fray during a cutting operation.
