In this study we proposed a processing method for improving the filtering capacity of conventional non-woven fabric used in air mask filters by electrospinning polyurethane nanofibers onto the surface of the non-woven fabric. We used FGM technology in controlling different electrospinning parameters to test which is the optimal process method for manufacturing. The morphology of the nanofiber in the non-woven fabric surface was investigated using FESEM. The filter test is done using an air filter chamber device that we constructed and fitted with CO2 and dust sensors. We tested the influence of the parameters (Distance from tip to collector, Electrospinning Time) in UFP filtration effectivity and CO2 absorbance.
