Fibre Felt

What is Fibre Felt in Liquid Filtration?

Fibre Felt is a key non-woven filter media for liquid bag filters. Mechanically needled polypropylene or polyester fibers form a dense 3D structure that enables depth filtration. It provides high dirt-holding capacity, excellent chemical resistance, and customizable properties, making it a versatile and efficient choice for industrial water filtration applications.

Why choose Srilan’s Fibre Felt？

• Three-Dimensional Network Structure.Srilan’s fiber felt uses needle-punched process, it creates a dense, labyrinthine web of interconnected fibers. This profound depth filtration mechanism traps contaminants throughout the entire material’s thickness, not just on the surface. This significantly increases dirt-holding capacity, reduces frequency of change-outs, and extends the filter bag’s operational lifespan compared to surface-filtering woven media.

• High Porosity and Permeability.Srilan’s fiber felt possess a lofty, porous structure with a high void volume. This provides immense internal space for contaminant retention while maintaining optimal fluid flow and lower pressure drop. This synergy of high dirt capacity and consistent permeability ensures efficient and extended filtration cycles without premature clogging.

• Tunable Performance and Customization.The performance of Srilan’s fiber felt is highly engineerable. By varying fiber type (e.g., PP, PET), fineness, and needling parameters (density, depth), the felt’s properties can be precisely calibrated. This allows for tailoring exact micron ratings, strength, thickness, and flow characteristics to meet specific application requirements, offering unparalleled design flexibility.
