Wire Cloth / Wire Mesh

Micronic Mesh

Details

Micron Mesh (sometimes called filter cloth) is typically used for filtration applications due to the extremely small openings (measured in microns) in the weave. There are 2 main types of weave – Dutch and Twilled Dutch with the most common variations listed below. Micron size, porosity and air flow are the parameters needed to determine the correct weave and size. Our Engineers can assist you with filtration weave selection for your application and work with you to create the filtration solution you need.

Plain Dutch Weave

Like plain weave, the wire in plain dutch weave is interwoven but the warp wires are thicker than the shute wires. These are arranged very close together to form a zero-mesh structure. This generates a weave that has high inherent stability with a relatively small mesh size. Plain dutch weave has excellent filtration qualities and can be easily cleaned of filtrate deposits and residual dirt.

Reverse Plain Dutch Weave

“Reverse” describes the fact that the warp wires of this weave are relatively thin and the shute wires are thick – in other words, the exact opposite of the standard dutch weaves. The reverse dutch design, sometimes referred to as “Microdur”, produces precisely defined pore openings that run under an angle to the surface of the mesh. The high number of warp wires increases the active filtration cross section.

Twilled Dutch Weave

As with plain weave, the shute wires of twilled dutch weave (TDW) are arranged as close together as possible. However, this weave has double the number of shute wires than plain dutch weave. A very small aperture is formed by three shute wires which cross in different directions and, together with the warp wires, create a channel that is open on two sides. The structure of this tight weave provides high filtration accuracy. Another variation is Open Twilled Dutch Weave where fewer shute wires are used to influence the filtration rate.

Reverse Dutch Twilled Mesh

An important version of the reverse dutch weave is the reverse dutch twilled weave. With this weave, the warp wires are also relatively thin – as in the case of the normal reverse dutch weave. The difference is the twilled weave pattern of the shute wires. This means that the warp wires are not as heavily deformed and physically stressed as in the case of plain weaves. The strength of this weave design is its suitability for applications that are subject to high levels of mechanical stress.

Broad Mesh

To optimize the filtration capacity of the cloth, the shute wires of the broad mesh twilled weave are arranged loosely instead of being close to each other. This means that the retention accuracy is lower than that of a classic twilled weave. Nevertheless, the accuracy is sufficient for the requirements of most applications. The surface of the BMT cloth is smooth on both sides, meaning that the filter can be easily cleaned.
