Filter media with superior nanofibre adhesion properties

N. Klit*, Fibertex Nonwovens A/S, Denmark

It is widely known that nanofibres enhance filter media performance by increasing filtration efficiency and improving de-dusting capabilities of the media when used in back pulse cleanable applications. However, nanofibres themselves cannot stand alone as a filter media due to lack of mechanical strength and mass and must be coated on a filter media in order to be converted into a pleat pack. Even though originally not designed for this purpose, conventional cellulose or synthetic filter media have been used until now often resulting in a combined filter media with unnecessary high-pressure drop and poor nanofibre attachment.

The presentation deals with the development of a synthetic tailor-made filter media with superior nanofibre adhesion properties characterised through VDI tests and a novel “instant result” test method for determining nanofibre adhesion properties...
