Dutch Weave Mesh
Dutch weave mesh (also called filter tresse) is a wire mesh with very densely packed wires, so that the openings do not form clear mesh gaps but tight pore channels. Usually, these are twill weaves, meaning they combine the tresse density with a twill weave pattern. A simple plain dutch weave has either zero mesh count in the warp or weft direction; the other direction holds the wires in position and is usually woven in twill.
Due to this extremely dense packing, dutch weave mesh achieves very fine filtration levels—much finer than the actual mesh size. The term “mesh size” is no longer used because it cannot be measured directly; instead, filtration fineness or “X µm tresse” specifies which particle sizes are retained.
The permeability of dutch weave mesh is lower than that of a normal mesh with the same nominal mesh size because fluids must pass through winding channels. However, the separation sharpness is very high—it almost acts like a metallic filter cake itself.
Applications:
- Hydraulic filters, fuel filters: Dutch weave meshes are often used as filter elements here (sometimes sintered onto a support for stability). They trap the smallest particles but remain robust and backwashable.
- Precision sieving: For example, in pharmaceuticals, when suspensions must be filtered, dutch weave mesh captures even fine crystals.
- Aerosol and air filters: Less common due to alternative media, but stainless steel dutch weave filters are used in aggressive gases.
Mechanically, dutch weave meshes are softer and more flexible (because the wires lie more loosely). Under pressure, they can compress slightly. Therefore, they are often laminated with support fabrics or sintered to ensure dimensional stability.
Terms: Twill tresse, Dutch weave. The latter specifically describes plain dutch weave where, for example, the warp is dense and the weft is thin and more open—resulting in so-called “open tresses” with high flow but fine filtration.
At GKD, dutch weave appears in product names like HIFLO-S, which are specially optimized for flow. They are a high-tech product—expensive to produce (lots of wire, slow weaving)—but unbeatable in the combination of fineness and durability.
Including dutch weave mesh in the glossary is essential to clarify the difference from “normal” wire mesh. It highlights GKD’s specialization in fine filtration, covering the range where alternative filters (paper, fleece) are finer but not fully metallic (temperature resistance, cleaning, lifespan). Dutch weave mesh fills this gap.
