Polypropylene (PP) filter cloth is used extensively in a host of liquid-solid separation applications, but all polypropylene filter cloth is not created equal. In general, filter cloths vary extensively in terms of material, warp, weft, weave, finish, and feed neck. Polypropylene cloth is no exception.

Textiles have a language all their own with terminology such as “weft,” a term that is also commonly referred to as “the fill” or the “filling yarn.” For instance, a cloth description of “polypropylene mono/multi” would refer to a cloth with a monofilament warp and a multifilament weft.
