A stretchable strap includes a side containing regions woven with frictionally enhancing material. Warp threads of both frictionally enhancing and non-frictionally enhancing material are woven to form a two-layer strap. Internal elastomeric threads provide a connection between the two layers as well as allow the strap to stretch. A method of making the strap is also provided wherein all elements are simultaneously woven on a loom.

What is claimed is: 1. A strap, comprising: a frictionally enhanced layer comprising a plain weave woven from a plurality of upper warp threads and a first plurality of weft threads, said upper warp threads comprising frictionally enhanced threads and non-frictionally enhanced threads; a non-frictionally enhanced layer comprising a plain weave woven from a plurality lower warp threads and a second plurality of weft threads, said lower warp threads comprising non-frictionally enhanced threads; and a connection between said frictionally enhanced layer and said non-frictionally enhanced layer comprising a plurality of internally located elastomeric warp threads and a plurality of binder warp threads both woven over and under each of a complete set of weft threads, wherein every other warp thread of said connection belongs to said plurality of internally located elastomeric warp threads, and wherein said complete set of weft threads comprises said first plurality of weft threads and said second plurality of weft threads, wherein every other weft thread belongs to said first plurality of weft threads; wherein said strap may be stretched from a non-elongated state to an elongated state, and wherein in both said non-elongated state and said elongated state at least a portion of said plurality of frictionally enhanced upper warp threads remain: i.) visible on a surface of said strap; ii.) substantially coplanar with said surface; and iii.) operable to provide friction enhancement along said surface. 2. The strap according to claim 1, wherein said frictionally enhanced threads comprise an elastomeric material. 3. The strap according to claim 2, wherein said elastomeric material comprises rubber. 4. The strap according to claim 1, wherein said elastomeric warp threads comprise rubber. 5. The strap according to claim 1, wherein said non-frictionally enhanced threads comprise at least one of polypropylene and nylon. 6. The strap according to claim 1, wherein said frictionally enhanced layer comprises: one or more frictionally enhanced regions comprising sections of said frictionally enhanced layer woven with said frictionally-enhanced upper warp threads; and one or more non-frictionally enhanced regions comprising sections of said frictionally enhanced layer woven with said non-frictionally-enhanced upper warp threads; wherein said one or more frictionally enhanced regions and said one or more non-frictionally enhanced regions are alternatingly disposed across a width of said strap. 7. The strap according to claim 1, wherein said frictionally enhanced layer comprises: first and second frictionally enhanced regions comprising sections of said frictionally enhanced layer woven with said frictionally-enhanced upper warp threads; and first, second and third non-frictionally enhanced regions comprising sections of said frictionally enhanced layer woven with said non-frictionally-enhanced upper warp threads; wherein said regions are disposed across a width of said strap in the following order: said first non-frictionally enhanced region, said first frictionally enhanced region, said second non-frictionally enhanced region, said second frictionally enhanced region, and said third non-frictionally enhanced region. 8. The strap according to claim 7, wherein: said first and second frictionally enhanced regions each contain six warp threads; said first and third non-frictionally enhanced regions each contain three warp threads; and said second non-frictionally enhanced region contains sixteen warp threads. 9. The strap according to claim 7, wherein: said first and second frictionally enhanced regions each contain eight warp threads; said first and third non-frictionally enhanced regions each contain four warp threads; and said second non-frictionally enhanced region contains twenty warp threads. 10. A strap, comprising: a frictionally enhanced layer comprising a plain weave woven from a plurality of upper warp threads and a first plurality of weft threads, said upper warp threads comprising frictionally enhanced threads and non-frictionally enhanced thread; a non-frictionally enhanced layer comprising a plain weave woven from a plurality lower warp threads and a second plurality of weft threads, said lower warp threads comprising non-frictionally enhanced threads; and a connection between said frictionally enhanced layer and said non-frictionally enhanced layer comprising a plurality of internal elastomeric warp threads and a plurality of binder warp threads both woven over and under each of a complete set of weft threads, wherein every other warp thread of said connection belongs to said plurality of internally located elastomeric warp threads, and wherein said plurality of internal elastomeric threads are located substantially between said frictionally enhanced layer and said non-frictionally enhanced layer, and wherein said complete set of weft threads comprises said first plurality of weft threads and said second plurality of weft threads, wherein every other weft thread belongs to said first plurality of weft threads; wherein said upper warp threads are arranged in frictionally enhanced regions and non-frictionally enhanced regions, said frictionally enhanced regions comprising a plurality of said frictionally enhanced upper warp threads, said non-frictionally enhanced regions comprising of plurality of said non-frictionally enhanced threads, wherein said frictionally and non-frictionally enhanced regions are alternatingly disposed across a width of said frictionally enhanced layer; wherein said strap may be stretched from a non-elongated state to an elongated state, and wherein in both said non-elongated state and said elongated state at least a portion of said plurality of frictionally enhanced upper warp threads remain: i.) visible on a surface of said strap; ii.) substantially coplanar with said surface; and iii.) operable to provide friction enhancement along said surface. 11. The strap according to claim 10, wherein said disposition of said frictionally enhanced and non-frictionally enhanced regions are in the following order: a first non-frictionally enhanced region, a first frictionally enhanced region, a second non-frictionally enhanced region, a second frictionally enhanced region, and a third non-frictionally enhanced region. 12. The strap according to claim 10, wherein said frictionally enhanced threads comprise an elastomeric material and said non-frictionally enhanced threads comprise at least one of polypropylene and nylon.
