Feasibility of Reusing Surgical Mask Under Different Disinfection Treatments	2020-05-20		.txt	text/plain	2693	161	52	This investigation found that dry heat and UVC irradiance could effectively disinfect the mask material without creating significant damage to surgical mask. Methods of disinfection studied include 100 ℃ dry heat, steaming, boiling, autoclave, 75% and 95% ethanol, UVC irradiance and household detergent. In assessing the destructive level of different disinfection treatments to surgical masks, filtration efficiency and fluid repellency were the parameters being focused in this study. Bead-like droplets were observed in all the samples treated with non-fluid disinfection methods, such as dry heat and UVC irradiation. For the samples underwent other disinfection treatments, the fluid-repelling layers were concluded to be damaged as the water droplets on the mask surface could not retain bead shape. Except household detergent water, all disinfection methods were effective in eliminating S.aureus in the mask material. Non-fluid contacting disinfection methods such as UVC irradiation and dry heat retained the highest performance regarding filtration efficiency, structural consistence and surface hydrophobicity even after three cycles of treatments.	./cache/cord-305282-x2zzzw43.txt	./txt/cord-305282-x2zzzw43.txt
