Abstract

Face masks will be used when the haze season arrived but the wearer still faced cough and dizzy after inhale the dirty air. This is due to a larger pore in the filter that allows fine particles past the conventional filter. So the purposed of this study is to develop an efficient face mask that can filter a fine particle using a nanofiber filter. Firstly, the test rig for filtration test using a PVC pipe and aluminum clamp to fit the filter were fabricated. Then, polyvinyl alcohol (PVA) mixed with distilled water was prepared for used in electrospinning process. For electrospinning process, the distance from spinneret and collector was constant which is 10 meter but the time collection of nanofibers was different which is from 2 minutes to 10 minutes. This is because to study the electrospinning collection time and effectiveness of the filtration. Next, the measurement of mass particle concentration was taken by using DustTrakІІ Aerosol Monitor Model 8530 EP. The average of the inlet measurement is 56 ppm while the lowest at outlet is 35 ppm. For the filtration effectiveness it can be seen an increased trend from t=0 minute to t=10 minutes. The longer electrospinning collection time the more effectiveness filtration of filter. Finally, Scanning Electron Morphology (SEM) was used to determine the morphology of PVA fiber and trapped particles. The average nanofiber diameter were from 209 nm to 305 nm (t=2 till t=10 minutes). Increasing the electrospinning collection time, produced thicker layer of nanofibers web, decrease the filter media porosity, increase the rate of fine particle stranded on the fiber and offer better capture effectiveness of particle on face mask.
