Abstract
The bottom machine direction yarns and the bottom cross machine direction yarns of a triple layer fabric are interwoven in a series of repeat units in which the bottom machine direction yarns pass below multiple nonadjacent bottom cross machine direction yarns to form bottom machine direction knuckles, and in which pairs of bottom machine direction yarns separated from one another by one bottom machine direction yarn form bottom machine direction knuckle pairs under a common bottom cross machine direction yarn. Each bottom machine direction knuckle pair forms two imaginary diagonal lines with a nonadjacent bottom machine direction knuckle pair such that each bottom machine direction knuckle pair in the diagonal lines is offset by two cross machine direction yarns and one bottom machine direction yarn.
