Reusable Face Barrier Mask in Cotton: Natural Dye use to Improve Antibacterial Properties

Face barrier masks were realized according to AFNOR SPEC S76-001 and ECOSTAND standard 082 2020 (ECOWAS standard). Cotton textile with specific properties according to previous standards was used to make face mask with pertinent barrier parameter after several washing steps. To compare with treated textile with natural dye which are naturally antibacterial properties, we use N’galamaAnogeissus leiocarpus. Masks made with a cotton fabric treated or not and washed or not; showed a barrier effect of 100 % efficiency, after spraying with a stream of sodium chloride aerosol and an aerosol based on bacteria. Additional with yellow fabric dying with N’galama there are is a reduction of the number of bacteria on the external surface of the masks by 33 %. All of the tests made by CERFITEX on fabric used and mask barrier physical and others properties are compliant with standard.
