Self-wrapping woven sleeve with wear indicator yarns and method of construction thereof

A method of constructing a protective sleeve, comprising:

• weaving an elongate wall having opposite edges extending lengthwise in generally parallel relation with one another between opposite ends with warp yarns extending generally parallel to the opposite edges and weft yarns extending generally transversely to the warp yarns and providing at least some of the weft yarns being formed from a heat-settable material;
• heat-setting the heat-settable material to bias the opposite edges into overlapping relation with one another to bound a cavity extending a longitudinal central axis of the sleeve between the opposite ends,
• wherein at least some of the warp yarns and/or weft yarns are bi-component yarns having a central core and an outer sheath encircling and encapsulating the central core, wherein central core and the outer sheath are different colors from one another, such that upon the outer sheath being split or worn, the central core becomes discernably visible, and
• further including providing the outer sheath having a maximum first outer diameter and providing the central core having a maximum second outer diameter, wherein the maximum second outer diameter is between 5 to 95 percent of the maximum first outer diameter.
