An one-step “dry” method of direct fluorination was applied to highly improve antibacterial properties of polypropylene nonwoven fabric. A treatment of polypropylene nonwoven fabric with F2/N2 mixture highly improved the barrier antibacterial properties with respect to test bacteria – Gram-positive Staphylococcus aureus (total reproduction suppression) and partially for Gram-negative Escherichia coli. A treatment with F2/N2/O2 mixture totally suppressed Candida albicans and microfungus reproduction. Polypropylene nonwoven fabric tensile strength was slightly increased after fluorination.
