High-Performance Non-Woven Filter Media for Liquid and Dry Filtration
Skytech Ultrafab Non-Woven Filter Cloth encompasses needle-punched, thermally bonded, spunbond, and melt-blown fabrics in polypropylene, polyester, nylon, fibreglass, and bicomponent fibres. With tortuous path depth filtration offering higher dirt-holding capacity, our non-woven media serves liquid bag filters, water treatment pre-filtration, industrial dust collection, and HVAC filtration across every industry.
What Is Non-Woven Filter Cloth?
Non-woven filter cloth is produced without interlacing yarns — instead, individual fibres are bonded together mechanically (needle-punching), thermally (hot-melt bonding), or chemically to form a coherent fabric. The resulting three-dimensional fibre matrix provides depth filtration, capturing particles throughout the full thickness of the media rather than on the surface alone.
Features and Benefits
- Higher Dirt-Holding Capacity: Three-dimensional fibre matrix captures particles at multiple depths, providing 3–10× the solids loading before blinding compared to woven equivalents
- Broad Weight Range: Available from 50 g/m² (lightweight spunbond) to 800 g/m² (heavy needle-felt) for pre-filtration through to primary filtration
- Multiple Technologies: Needle-punched, thermally bonded, spunbond, and melt-blown — each technology optimised for different filtration applications
- Surface Treatments: Singed, calendered, membrane-laminated, and antistatic finishes to optimise particle capture and surface behaviour
- Wide Width: Rolls up to 2.5 m wide supplied for large-scale filter press cloth and air filtration panel conversion
- Chemical Resistance: PP and PES options provide excellent chemical compatibility across the full pH range of industrial process liquids

Applications
- Liquid Bag Filtration: Needle-felt bags for paint, ink, resin, chemical, and water treatment bag filter housings
- Industrial Air Filtration: Needle-felt and thermally bonded media for pulse-jet and shaker baghouse dust collectors

- Water Treatment: Melt-blown media for depth pre-filtration ahead of RO membranes in water treatment plants
- Filter Press Cloth: Non-woven media as an alternative to woven cloth in filter presses where higher dirt-holding capacity is more important than precise micron cut-off
