Is Polypropylene Filter Cloth Right for My Application?

Tuesday, August 29, 2017

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.

Polypropylene Filter Cloth

This is a Polypropylene Mono/Multi cloth being used in the beverage industry. Our experts will help you navigate through the material selection process including warp, weft, weave, finish, feed neck, edge sealing, and cloth attachment.

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.

So, why might you want to select a polypropylene filter cloth for your filter press needs? Here are just a few reasons:

  • Allows for excellent cake release, particularly if the cloth utilizes a “satin weave”
  • Excellent resistance to alkalis
  • Excellent resistance to most acids, with the exception of chlorosulfonic acid
  • Very low or no moisture absorption
  • Excellent strength and the cloth maintains its strength even after repeated flexing
  • Light in weight with a specific gravity of 0.91
  • We can supply it to you in different warps/wefts including monofilament/monofilament, monofilament/multifilament, and different weaves including plain, twill, and satin
  • Not attacked by mildew
  • Good for temperatures up to ~180o F
