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 the 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 the 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.

Abstract
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.
