1) Plain Dutch weave: woven as a plain weave. Each warp wire and each weft wire passes
over and under the next adjacent complementary wire, as in normal
Plain Weave, except the warp wires are larger in diameter than the
weft wires. This allows a greater mesh count in the weft direction.
Characteristics: ”zero”—aperture, more solid than square or
rectangular mesh, relative high open area, suitable for all kinds
of filtration.
2) Dutch twilled weave: Each warp wire and each weft wire passes over and under the next
two adjacent complementary wires, as in a normal Twill Weave,
except the warp wires are larger in diameter than the weft wires.
This allows a greater mesh count in the weft direction. This weave
pattern enables the weft wires to be woven more densely, and much
smaller aperture sizes can be achieved without forsaking cloth
thickness.
Characteristics: ”zero” aperture, light-proof woven, high
resistance due to tight wire position, extreme low absolute grade
of fineness(down to 5-6μm),high filtration performance in case of
low viscose medium, it is the finest filtration in hydraulic
systems, especially for critical applications as aero-space,
fuel-and combustion.
3) Reverse Dutch weave: The apparent difference of Reverse Dutch Weaving compared with standard Dutch weave lies in the thicker warp wires and less weft wires. Reverse Dutch woven stainless steel wire cloth offers finer filtration and finds popular application in petroleum, chemical, food, pharmacy and other fields.
