Plain dutch weave pattern is the same as plain weave, but the weft wires are of smaller diameter than the warp wires. The wires are woven tightly together resulting in a small triangular opening. This weave produces a strong cloth with a small open area and greater strength with a good flow rate to make it suitable for high pressure filtration.
The shapes and position of the openings aid particle retention and increase filter cake formation. Plain dutch weave mesh is most frequently used for high pressure filtration processer to separate from other medium in industry of spaceflight, petroleum, hemical, etc.
Twill Dutch Weave is similar to plain dutch weave but it uses a double layer of weft wires woven as a twill pattern. Dutch weave is very strong to support greater loads and finer openings than the plain dutch weave mesh with a controlled flow rate and is suitable where high pressure filtration is required.
The shapes and position of the openings aid particle retention and increase filter cake formation. Plain dutch weave mesh is most frequently used for high pressure filtration processer to separate from other medium in industry of spaceflight, petroleum, hemical, etc.
Twill dutch weave mesh is most frequently used in applications where the filtering of heavy material necessary. Such as aerospace industry, petroleum and chemical industry, beer, machines, etc.

The yield of such a roll is equivalent to several hundred ‘screen packs’ in a conventional screen changer and lasts many months in non-stop operation.
PFM Screen offers wide range filter screens for automatic, continuous screen changers used for polymer melt filtration in every segment of plastics
Processing including: blown film, blow molding,
Sheet and film extrusion, filaments & fibers, pipe and profile, pelletizing, BIAX (BOPP and BOPS).
