In addition to yarn fiber materials and yarn designs, weave patterns are an important factor influencing filter cloth performance. Required cake release characteristics, abrasion resistance, resistance to acid and alkaline environments, particle retention, and susceptibility to blinding all factor into selection of a weave pattern for your particular filter press operation.

The plain weave filter cloth is one of the simplest weave patterns. The warp and filling threads cross alternately. Plain-woven fabrics are generally the least pliable, but they are the most stable. Characteristics include high particle retention and low resistance to blinding with average cake release properties.
The twill weave is characterized by a diagonal rib, or twill line. Each warp floats over at least two or more consecutive fill yarns, enabling a greater number of yarns per unit area than a plain weave, while not losing a great deal of fabric stability. Characteristics include an average resistance to blinding, average cake release, and good mechanical strength.
The face of the satin weave fabric consists almost completely of warp produced in the repeat of the weave. This is the most flexible of weave patterns and conforms very easily around most contoured surfaces. Satin weaves are usually four, five, eight, or twelve harness. Characteristics include excellent cake release, average retention, and excellent resistance to blinding.
The basket weave is a variation of the plain weave where two or more warp yarns cross alternately with two or more filling yarns, resembling a plaited basket. This weave is more pliable and stronger than a plain weave, but is looser and not as stable. The basket weave is typically used for backing (support) cloth and basic filtration applications.
The leno weave is a locking-type weave in which two or more warp threads cross over each other and interlace with one or more filling threads. It is used primarily to prevent shifting of fibers in open weave fabrics and only for backing (support) cloths.
