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.
