Product Features & Benefits

Filter Media Needle Felting

Needle Punching Technology

High-density needle punching ensures uniform fiber distribution, enhancing mechanical strength and dimensional stability. This structure provides excellent air permeability while capturing fine dust efficiently.

Filter Media Treatment

Singeing Treatment

Singeing removes surface fuzz and loose fibers, preventing dust re-entrainment and improving cleaning efficiency. It creates a smooth surface ideal for pulse-jet cleaning systems.

ePTFE Membrane Lamination

Membrane Lamination

A PTFE or ePTFE microporous membrane is laminated onto the fabric surface to achieve ultra-fine filtration. It enables ≤5mg/m³ emission levels, reduces pressure drop, and significantly extends bag life.

Filter Media Treatment

Heat Setting

Stabilizes the fabric dimensions after processing, ensuring consistent fit, shrink resistance, and compatibility with bag cages.

Aramid Fiber

Anti-static Finish

Conductive fibers or surface treatments prevent static charge buildup in explosive dust environments (e.g. flour, coal, aluminum powder).

Hydrophobic and Oleophobic Treatments

Oil & Water Repellent Finish

Improves resistance to moisture and sticky particles, ideal for humid or oily dust applications like food, biomass, or carbon black.

As a dust filter cloth manufacturer, we provide fully customizable fabrics to meet specific application needs. Options include:

Parameter Range / Options
Weight (Grammage) 350 g/m² – 800 g/m²
