Abstract
A self-extinguishing fire resistant elastic strap material is disclosed, as is a method of fabricating the same. The material is comprised of a tubular fabric of fireproof yarns having a hollow core, elastic and hence combustible yarns being disposed entirely within the core, the elastic yarns being frictionally clampingly engaged at spaced positions to the surrounding fabric, the elastic yarns being tensioned in the formed condition of the fabric to effect foreshortening of the fabric when the tension in the elastic yarns is relaxed.
