Abstract

A multilayer textile sleeve and method of construction thereof is provided. The sleeve includes a textile wall having opposite edges extending lengthwise along a longitudinal axis of the sleeve between opposite ends. The opposite edges are configured to overlap one another to bound a central cavity of the sleeve. The wall has an inner layer with opposite inner and outer faces and an outer layer with opposite inner and outer faces. The inner and outer layers overlap one another and are constructed of interlinked yarn. The inner and outer layers are integrally connected to one another across interlinked portions adjacent the opposite edges by yarn common to each of the inner and outer layers.

First claim

What is claimed is:

1. A multilayer textile sleeve, comprising:
a textile wall having a width extending widthwise between opposite edges and a length extending lengthwise along a longitudinal axis of the sleeve between opposite ends, said wall having an inner layer with opposite inner and outer faces and an outer layer with opposite inner and outer faces, said outer face of said inner layer and said inner face of said outer layer facing one another in overlying relation and being constructed of woven warp and weft yarns;
said outer face of said inner layer and said inner face of said outer layer being integrally connected to one another via interlinked portions extending along the entirety of said opposite edges from one of said opposite ends to the other of said opposite ends, each of said interlinked portions including a plurality of said weft yarns from at least one of said inner and outer layers being interwoven with a plurality of said warp yarns from the other of said inner and outer layers, said interlinked portions extending widthwise from each of said opposite edges along only a portion of said width and overlapping one another in an overlapped region to bound a lengthwise extending central cavity; and
wherein said inner face of said outer layer and said outer face of said inner layer remain completely detached from one another along a non-overlapped intermediate region extending over a plurality of said warp yarns of said inner and outer layers and over the entirety of a portion of said width extending from one of said interlinked portions to the other of said interlinked portions.

2. The sleeve of claim 1 wherein at least one of said inner and outer layers includes heat-set weft yarns to bias said wall into a self-wrapped tubular configuration.

3. The sleeve of claim 1 wherein said interlinked portions include a plurality of weft yarns of the inner layer being interwoven with a plurality of warp yarns of the outer layer and a plurality of selected weft yarns of the outer layer being interwoven with a plurality of warp yarns of the inner layer.

4. The sleeve of claim 3 wherein said warp yarn of said inner layer remain entirely within said inner layer and said warp yarn of said outer layer remain entirely within said outer layer.
