Abstract:
1. A method of making a corrosion-resistant fabric having an increased thickness comprising: (a) providing an open woven layer including pairs of twisted together warp yarns interwoven with weft yarns, wherein adjacent pairs of twisted together warp yarns are twisted in opposite directions of twist; (b) applying tensile force on the adjacent pairs of twisted together warp yarns, wherein the adjacent pairs of twisted together warp yarns having opposite directions of twist apply torque on each weft yarn, and urge each weft yarn to become undulated in a sinusoidal profile, said sinusoidal profile having a generally “C” shaped configuration extending between the adjacent pairs of twisted together warp yarns, wherein the generally “C” shaped configuration provides an increased thickness of the fabric as measured from the high point and the low point of the sinusoidal profile; and (c) retaining said generally “C” shaped configuration by disposing a bonding agent in the form of a polymeric coating over at least portions of said pairs of twisted together warp yarns and at least portions of said weft yarns.
