    Abstract: A woven industrial fabric, including a plurality of warp yarns 20 interwoven with a plurality of weft yarns 22. At least a portion of one of the plurality of warp 20 and the plurality of weft 22 yarns includes yarn assemblies 12. Each yarn assembly 12 is comprised of at least a first 14a and a second 14b yarn. The yarns 14a, 14b are structured and arranged in the woven fabric so as to be in generally continuous, contiguous contact with each other substantially throughout the fabric.
