Question 1

In which applications is Polyester filter cloth preferred over PP?

Accepted Answer

Polyester is preferred in high-temperature applications (up to 150°C), processes involving oxidizing acids, and belt presses where extreme mechanical pulling strength is needed.

Question 2

Is polyester filter cloth resistant to alkaline cleaning solutions?

Accepted Answer

Polyester has poor resistance to concentrated alkalis at hot temperatures, which can cause fiber hydrolysis. For hot alkaline filtration, Polypropylene or Nylon must be used.

Question 3

What weave style is best for mineral ore mining dewatering?

Accepted Answer

We recommend our satin-weave polyester multifilament cloths. The satin weave offers high water flow rates, superior particle capture, and doesn't blind when processing abrasive metal ores.

Question 4

Do you supply pre-fabricated filter cloth with barrel necks?

Accepted Answer

Yes, we supply ready-to-install B2B made-ups, including double-panel cloths connected with durable, chemical-resistant PVC or EPDM barrel necks.

Question 5

How does the moisture rating affect Polyester performance?

Accepted Answer

Polyester resists water well but is subject to hydrolysis at high temperatures (above 120°C) under high pressure. For wet, hot, high-pressure steam, specialized blends are required.
