Abstract: A visual barrier windscreen comprising a first series of monofilament threads, a second series of monofilament threads, and a third series of monofilament threads. The first series of threads may be formed in pillar stitches, the second series of threads may be formed in zig-zag stitches, and the third series of threads may be formed in zig-zag stitches. A pattern of wind-passage holes may be formed by a cooperation of the first series, the second series, and the third series of threads. At least a 75% visual block may be attained with the cooperation of the first series, the second series and the third series of threads. The cooperation of the first series, the second series, and the third series of threads may achieve an air flow permeability that may be greater than 755 cfm/ft2.

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.
