Twill Weave (TW)
Stronger than plain weave. Each shute wire alternatively crosses over two, then under two warp wires, producing a diagonal pattern. The wire diameter for both warp and shute is normally the same. Twill weave can be used to accommodate a heavier than standard wire diameter in association with a given mesh. Specifications finer than 300 are normally twill weave.
Twilled Dutch Weave (TDW)
– Similar to plain dutch weave, except that the weave pattern is twill, i.e. a double layer of shute wires. There are no openings in the true sense of the word, and the filtrate follows a tortuous path through the triangular passages in the mesh. Twilled Dutch Weave is a surface filtration medium, often used under high pressure.
