Abstract

A woven sleeve and method of construction thereof is provided. The sleeve has a wall with opposite edges extending lengthwise along a longitudinal axis between opposite ends, wherein the opposite edges are wrappable into overlapping relation with one another to contain the wires within a cavity of the sleeve. The wall is constructed from warp yarns extending along the longitudinal axis and fill yarns extending transversely to the warp yarns. The fill yarns are provided as transparent or substantially transparent monofilaments and the warp yarns are provided as yarns including a multifilament yarn and at least one conductive wire, wherein the conductive wire wrapped about the multifilament yarn.

First claim

What is claimed is:

1. A protective textile sleeve for routing and protecting elongate members from exposure to abrasion, from exposure to EMI, and for viewing the elongate members contained in the sleeve, comprising:
a woven wall having opposite edges extending lengthwise along a longitudinal axis between opposite ends, said opposite edges being wrapped into overlapping relation with one another to contain the elongate members within a cavity of the sleeve, said wall having warp yarns extending along said longitudinal axis and fill yarns extending transversely to said warp yarns, said fill yarns being substantially transparent monofilaments to allow the elongate members within the cavity to be viewed from outside of said protective textile sleeve and said warp yarns including a multifilament warp yarn and at least one conductive wire twisted or served about said multifilament warp yarn, said fill yarns being bonded with said at least one conductive wire.

2. The protective textile sleeve of claim 1 wherein said multifilament warp yarns are colored to enhance the ability to distinguish the elongate members contained within the cavity of the sleeve from the multifilament warp yarns.

3. The protective textile sleeve of claim 1 wherein at least some of said monofilament fill yarns are provided as bicomponent monofilaments, including a substantially transparent central core and a substantially transparent outer sheath, said outer sheath having a lower melt temperature than said central core, said central core being heat-set to bias said opposite edges into overlapping relation with one another.

4. The protective textile sleeve of claim 1 wherein each of said fill yarns is provided with a central core and an outer sheath and wherein said outer sheath is meltable and said central core is heat-settable in a single operation.

5. The protective textile sleeve of claim 1 wherein each of said fill yarns is provided with a central core and an outer sheath and wherein said outer sheath is meltable at a temperature which is insufficient to heat-set said central core.

6. The protective textile sleeve of claim 1 wherein said at least one conductive wire includes a plurality of conductive wires, at least some of said plurality of conductive wires being wrapped in opposite helical directions about said multifilament warp yarn.
