The structure of Dutch woven cloth has different mesh counts in weft and warp direction. Suitable match of wire dia. and mesh count can realize the filtration density that are unrealizable for square mesh. Common dutch woven wire cloth has more weft wires than warp wires, and the warp wire dia. is usually bigger than that of the warp wires; Due to its unique structure and weave pattern, dutch woven wire cloth is more used in fine filtration than normal s.s. square mesh.Present densest dutch woven cloth can have the mesh opening size as small as 3 microns.So we also call dutch woven mesh micron-grade filter cloth.
Twill dutch weave wire cloth including Dutch and twill weaving to provide a fine mesh filtering cloth. Shute wires are passed over and under two warp wires, providing a tight and fine filter with tapered openings. The weaving process allows for the used of very fine wires, to micron size, can be used in aerospace industry.

Usage:
Twill dutch weave wire mesh play an important role in the aerospace field. Commercial, military and general aviation aircraft all have wire cloth filters to protect critical systems from contamination. Premature engine overhauls caused by dirt and debris cost airlines millions in maintenance and lost passenger revenue and hurt military readiness. The role of wire cloth in aerospace engine parts makes flights safer, smoother and quieter. Here we will look at three categories where wire cloth and filters are critical to safe flight operations, airplane noise reduction and passenger comfort.
