1. A woven mesh support structure comprising:
a plurality of first yarns;
a plurality of second yarns; and
a plurality of third yarns;
wherein:
said yarns are woven in a leno weave arrangement;
the composition of each said third yarn is such that at least a portion of the surface thereof melts when said third yarn is exposed to elevated temperatures, wherein exposure of said woven mesh to such a third yarn melt temperature does not result in any significant melting of said first or second yarns;
each said third yarn is intertwined with one said second yarn;
each said intertwined pair of second and third yarns is positioned in said woven mesh such that said third yarn and said second yarn thereof are disposed alternatingly on either side of said first yarn at intersections of said yarns; and
said woven mesh, having previously been exposed to elevated temperatures, is configured such that at least a portion of the surface of said third yarns, having been partially melted at said elevated temperatures, are adhered to the surface of each said first yarn and said second yarn substantially only at contact points there between.
