The unique fine filament nonwoven technology is made from a wide variety of polymers and blends using mono or bico fibers. 

The high flexibility and broad customization options provide benefits in a wide range of markets and applications – from roofing membranes to liquid filtration, as well as specific applications such as dehumidification products and artificial turf.

Marketed under the Filtura brand, the fine denier technology is specifically suited for liquid filtration, for example coolants and lubricants. The technology provides high efficiency and a regular surface, as well as new capabilities with PET-PA and PET-PE nonwovens. Support media applications for glass fiber, nano and activated carbon also benefit from the lightweight fine denier nonwovens as protective layers.

Freudenberg’s innovative fine denier spunbond materials rely on flexible manufacturing capabilities, which enable a high level of customization. They can be made of PET, PE or PP, not only as 100% composition but also in many different combinations, for example PET/PE, PET/coPET or PET/mPP, using mono or bico fibers with titer ranging from 2.5 to 3 dtex. The material weight spans 17 to 140gsm. The nonwovens are strongly bonded thanks to thermal bonding provided either by flat calendering or point sealing. The technology enables lightweight solutions with high tensile and tear strength, as well as a smooth and uniform surface.
