Filter Cloth Explanation
Industrial filter cloths are products made of different filter materials with complex technical weaving.
The choice of material is made according to the chemical environment and temperature. The choice of the type of weave meets the requirements of filtration quality, mechanical resistance and also the filter cake discharge qualities (anti-adhesion).
There are also several types of yarn: monofil, mutifil and staple fibre. Yarns of different types can also be used in a complex weave.
The synthetic filter fabric can be given different types of treatment, from simple dimensional stabilisation to hydrophobic or hydrophilic surface treatment.
For pharmaceutical, food or medical processes some products have cleanliness and food contact approvals such as CE 1935/2004, CE 10/2001, FDA Title21…
Filter cloth selection is one of the key variables in the optimization of any filter press or rotary vacuum precoat filter. Critical considerations include the cloth’s resistance to blinding, ease of filter cake discharge, resistance to chemical attack, thermal properties, abrasion resistance, particle retention, and more.
Factors to consider in choosing the best filter cloth for your application, all having an impact upon filter cycle time and cloth life, are:
Fiber material such as polyester, polypropylene, and cotton
Weave pattern
Weight per square yard of the fabric
Frazier air permeability measured in CFM by ASTM Method D-737-96
