Twill Dutch Weave Micronic Filter Cloth
The term "Twill" indicates the warp and weft (shute) wires pass alternately over two and under two wires. The term "Dutch" refers to the use of a heavier warp wire diameter in conjunction with a lighter weft wire diameter. In a Twill Dutch Filter Weave the weft wires are driven up so tightly that there is always a weft (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.
