Abstract
A visual barrier windscreen includes a first series of monofilament threads formed in pillar stitches extending in a warp direction and a second series of monofilament threads formed in zigzag stitches extending in a first weft direction relative to the pillar stitches and binding adjacent pillar stitches. A third series of monofilament threads may be formed in zig-zag stitches extending in a second weft direction, opposite to the first weft direction, and also binding adjacent pillar stitches. A pattern of hexagonal wind-passage holes may be formed by cooperation of the pillar stitches and zig-zag stitches. At least a 75-80% visual block may be attained with the cooperation of the pillar stitches and zig-zag stitches.
