Twill Dutch Weave Filter Cloth

In a Twill Dutch (Hollander) Weave the weft  wires are driven up so tightly that there is always a shute wire above and below the warp wires, creating a weave with the warp wires completely covered. The flow-pass geometry is extremely tortuous, allowing reasonable flow rates while insuring excellent particle size retention.
