Twill Dutch Weave Micronic Filter Cloth

The term "Twill" indicates the warp and shute (weft) 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 shute wire diameter.

There are two variations of Twill Dutch Weave, Twill Dutch Double Weave and Twill Dutch Single Weave.

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