Abstract:　Polypropylene　(PP)　nonwovens　have　been　widely　used　in　disposable　protective　masks　and　protective　clothing,　which　are　essential　to　protect　healthcare　workers　from　highly　infectious　diseases　such　as　COVID-19.　However,　realizing　the　disinfection reusable　function　of　PP　nonwovens　to　reduce　carbon　emission　or　white　waste　pollution　after　extensive　use　has　been　still　a　great　challenge.　Herein,　Durable　Antimicrobial　and　Anti-fungal　Post-disinfection　polypropylene　nonwovens　were　developed　by　co-grafting　of　Triclosan　and　Chitosan.　The　antibacterial　performance　test　results　showed　that　the　as-prepared　co-grafted　polypropylene　nonwoven　has　a　＞　99.9%　of　antimicrobial　efficiency　against　E.　coli,　S.　aureus　as　well　as　multi-drug-resistant　P.　aeruginosa,　and　the　excellent　anti-fungal　performance　against　fungus　(C.　albicans)　and　mold　(A.　niger).　Moreover,　it　retained　excellent　Antimicrobial　and　Anti-fungal　Properties　after　disinfection　3　times　with　boiling　water,　40　×　diluted　84　disinfectant　and　75%　alcohol　for　5 min.　This　work　provided　ideas　for　developing　more　effective　pathogen　protection　and　longer-lasting　personal　protective　equipment　to　reduce　the　environmental　impact　of　medical　masks　and　personal　protective　equipment　in　terms　of　energy　consumption,　carbon　emissions　and　waste　generation.　Graphical　Abstract:　Polypropylene　(PP)　nonwovens　have　been　widely　used　in　disposable　protective　masks　and　protective　clothing,　which　are　essential　to　protect　healthcare　workers　from　highly　infectious　diseases　such　as　COVID-19.　The　as-prepared　PP-AA-CS-TCL　nonwovens　exhibited　an　antibacterial　efficiency　of　＞　99.9%　againstE.　coli,　S.　aureus,　andP.　aeruginosa　as　well　as　the　excellent　anti-fungal　properties　against　C.　albicans　and　A.　niger.　And　the　antimicrobial　and　anti-fungal　activities　were　maintained　even　after　disinfection　3　times　with　boiling　water,　40x　diluted　84　disinfectant　and　75%　alcohol　for　5　minutes　each.　This　provides　a　new　way　of　thinking　about　reusing　disposable　surgical　products　with　polypropylene　nonwoven　and　reducing　environmental　pollution.　(Figure　presented.)　©　The　Author(s),　under　exclusive　licence　to　the　Korean　Fiber　Society　2024.
