The top MD yarns and the top CMD yarns are interwoven in a series of repeat units and the bottom MD yarns and the bottom CMD yarns are interwoven in a series of corresponding repeat units. The set of top MD yarns comprises a first number of top MD yarns in each repeat unit, and the set of bottom MD yarns comprises a second number of bottom MD yarns in each repeat unit, wherein the second number being greater than the first number.
