Face Mask Media Manufacturing
Presenter:  Alfiya Ansar, Cummins Filtration

Cummins has continuously led innovations in design and materials for diesel filters since 1958 and in the 1990 was the first to introduce non-woven materials, specifically composites with melt blown fiber, into lube and fuel products.  Shortage of meltblown media used in PPE (personal protective equipment) is a current critical concern since the emergence of coronavirus-2 or SARS-CoV-2 (COVID-19). While Cummins works almost exclusively with high temp polymers like polyester and nylon, it was possible to leverage Cummins technology to melt blow polypropylene media with finer fibers needed for surgical face masks and respirators. Expertise from Dr. Peter Tsai and collaboration from Oakridge labs on electrostatic charging of the media ensured that the media met efficiency needs of level 2 surgical masks (ASTM F2100) and NIOSH N95 respirators. Protective Spunbond Polyprolypene layers are added on the melt blown media, to meet the requirements PPE products.
