Patent ID: 8387750

Claim:
A method of making a fabric structure comprising: (i) weaving a webbing comprising: a plurality of ground yarns that form a sheath; a plurality of elongation yarns surrounded by the sheath, wherein the elongation yarns are partially oriented yarns; and a plurality of binder yarns; wherein the ground yarns, the elongation yarns, and the binding yarns extend in a substantially warp direction, the weaving step further comprising: (a) weaving a first connection segment, including weaving the plurality of binder yarns with the ground yarns and the elongation yarns; (b) weaving an expansion segment, including (1) at a plurality of attachment points, connecting the elongation yarns to the sheath by, between outer edges of the sheath, weaving a plurality of lateral yarns extending in a substantially weft direction in between the elongation yarns and, at the outer edges of the sheath, weaving the lateral yarns with the sheath ground yarns; and (2) at least one non-attachment point, weaving the lateral yarns with the ground yarns but not weaving the lateral yarns with the elongation yarns; and (3) weaving the plurality of binder yarns with the plurality of ground yarns of the sheath without weaving the binder yarns with the elongation yarns; and (c) weaving a second connection segment, including weaving the plurality of binder yarns with the ground yarns and the elongation yarns; and (ii) applying heat to the expansion segment, whereby in the expansion segment the length of the elongation yarns is reduced to be shorter than the length of the ground yarns.
