Wire Mesh

A twill pattern follows the same principle as plain weave, but each passes alternately under and over two warp wires and vice versa. As a consequence of the woven path, the strand is deformed less during weaving, which not only allows a larger diameter wire to be used, but also results in a stronger structure when compared to the plain weave counterpart. Twill weave meshes are generally woven with apertures smaller than 70 microns, 250 mesh for example, but coarser specifications can be produced when required.

In a Plain Dutch Weave, the diameter of the warp wire is larger than the weft, and the mesh is formed by weaving a limited number of warps with the maximum number of weft wires woven tightly together, producing a cloth with no readily visible apertures. This mesh is strong and stable, easy to clean and with a good flow rate suitable for high pressure liquid/solid separation.

Twill Dutch Weave is produced with the weft wires packed together in the same principle as Plain Dutch Weave, but with double the number of weft wires woven in an over two, under two pattern.

The weft wires overlie each other creating a sinuous path of filtration. The cloth is very robust with a smooth surface and the finer weft wires and smaller pore sizes provide excellent flow characteristics.

The finest filtration rates are obtained with this type of weave.

This is produced in a reverse of the Plain Dutch Weave wire arrangement, whereby finer warp wires are positioned tightly together and a thicker weft wire is woven in at set intervals. The cloth is mechanically strong with a high throughput and it performs particularly well in high pressure vertical and horizontal filter leaf applications where backwashing and filter cake removal are important

Manufactured as a Reverse Plain Dutch Weave in a twill pattern, which reduces the deformation of the warp wire, this cloth is very stable and particularly strong in the warp direction with a high flow rate. It is well suited to high pressure filtration including continuous filter screens used in polymer filtration and selected sand screen applications for which custom/bespoke specifications have been developed.

Typically a rectangular aperture, each warp wire passes over four wires and under one to provide a very smooth surface on one side which encourages the efficient removal of filter cake. The cloth is also exceptionally strong with high flow rates and good dewatering qualities.
