A Dutch Weave, but woven in a twill pattern which enables twice as many weft wires to be woven in the same area as a Plain Dutch Weaves to achieve a finer filter opening . Typically produced for very fine filtration application- 10 micron and finer.

A Reverse Plain Dutch Weave. The warp wires are smaller and spaced closer together than the weft wires. This weave allows the use of high tensile wires which offers the most durable and stable fine filter cloth.
The Reverse Twilled Dutch weave ( KPZ-Microdur ) is woven under the same preferences and gives in special versions extreme rigid cloths with filtration grade down to 45 micron.
