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 microfungus reproduction. Polypropylene nonwoven fabric tensile strength was slightly increased after fluorination.

We investigated antimicrobial properties of polyester fabrics with photochemical activity that they gained owing to modification by small amounts of undoped and metal-doped titanium dioxide...

A new technology for hydrophobization of synthetic fiber materials was described. This technological approach is based on formation of nanosized fluoropolymer coatings from solutions of...
