Wrappable abrasion resistant, reflective thermal protective textile sleeve and method of construction thereof

Abstract

A wrappable textile sleeve and method of construction thereof is provided. The sleeve includes a woven wall having opposite inner and outer edges extending in a lengthwise direction along a central longitudinal axis of the sleeve between opposite ends. The opposite inner and outer edges are wrappable into overlapping relation with one another to form an inner tubular cavity. The wall has an innermost woven layer and an outermost woven layer woven in attached relation with one another at one of the opposite inner and outer edges. A reflective layer is sandwiched between the innermost woven layer and the outermost woven layer, such that the outermost woven layer protects the underlying reflective layer against abrasion.

What is claimed is: 
     
         1 . A method of constructing a wrappable textile sleeve, comprising:
 weaving a wall extending in a lengthwise direction along a longitudinal axis between opposite ends;   attaching a reflective layer to said wall; and   folding said wall in overlapping relation with itself to form an innermost layer of said wall and an outermost layer of said wall and sandwiching said reflective layer between said innermost and said outermost layers.   
     
     
         2 . The method of  claim 1  further including weaving said wall with warp yarns extending in the lengthwise direction generally parallel to said longitudinal axis and weft yarns extending generally transversely to said longitudinal axis between said opposite edges and heat-setting at least some of said weft yarns to impart a bias on said wall to bring opposite lengthwise extending edges of said wall into overlapping relation with one another. 
     
     
         3 . The method of  claim 2  further including weaving said warp yarns of said innermost layer with insulative multifilaments. 
     
     
         4 . The method of  claim 3  further including weaving said warp yarns of said outermost layer with monofilaments. 
     
     
         5 . The method of  claim 4  further including providing the monofilaments of said outermost layer as transparent monofilaments. 
     
     
         6 . The method of  claim 2  further including weaving said warp yarns of said outermost layer with monofilaments. 
     
     
         7 . The method of  claim 1  further including bonding said reflective foil layer to one of said innermost woven layer and said outermost woven layer. 
     
     
         8 . The method of  claim 1  further including weaving said wall on a narrow fabric loom.
