Organic Antimicrobial Agents: Sib npaug Broad-Spectrum Efficiency nrog kev ua tau zoo
1. Muaj ntau haiv neeg hauv Mechanisms of Action
Organic antimicrobial agents encompass ntau ntau yam tshuaj cov qauv-xws li ethers, phenols, thiab cawv-uas yog lub luag haujlwm tseem ceeb ntawm kev cuam tshuam kev ncaj ncees ntawm microbial cell membranes (xws li, quaternary ammonium ntsev) los yog inhibiting kev ua ntawm cov metabolic enzymes tseem ceeb (xws li, . Piv txwv li, Dow Corning's AEM5700, silicone -raws li quaternary ammonium ntsev, yog covalently bonded rau fiber ntau; qhov no tso cai rau nws kom tswj tau cov kev siv tshuaj tiv thaiv kab mob kom ruaj khov txawm tias tom qab dhau ntau tshaj 50 tus qauv laundering. Cov neeg ua haujlwm zoo li no tau siv dav hauv kev ua tiav ntawm cov ntaub paj rwb, muaj peev xwm tshem tawm 99% ntawm * Staphylococcus aureus * thiab * Escherichia coli * hauv peb feeb xwb.
2. Qhov zoo ntawm kev ua kom haum
Cov neeg ua hauj lwm pawg no nthuav tawm qhov zoo tshaj plaws nrog cov txheej txheem tsim khoom, tso cai rau kev siv ncaj qha rau polyester / nylon blend fabrics ntawm lub ncoo - qhuav- txoj kev kho, los yog rau kev koom ua ke rau hauv polypropylene dope thaum lub sij hawm hloov spinning theem. Tebchaws Asmeskas -tsim iHeir-333- tsis yog-leaching antimicrobial tus neeg sawv cev-ua haujlwm cationic mechanical-puncture mechanism los tsim cov txheej txheem tshuaj tua kab mob mus tas li, ua rau nws zoo tagnrho rau cov ntawv thov kev nyab xeeb siab xws li kev hnav khaub ncaws kho mob. Txawm li cas los xij, qhov kev txwv tseem ceeb ntawm cov neeg ua haujlwm no yog lawv cov thermal stability tsis txaus; tshwj xeeb, qee yam khoom uas muaj aldehyde pawg yog nquag decomposition ntawm kub curing kub, muaj peev xwm tso cov pa phem.
Inorganic Antimicrobial Agents: Ib qho kev sib txuas ntawm lub neej ntev thiab ua haujlwm nthuav dav
1. Lub luag haujlwm tseem ceeb ntawm Silver-Raws li Nanomaterials
Spinning-qib nyiaj-raws li cov tshuaj tiv thaiv kab mob- piv txwv los ntawm ANA-F2 series- siv lub ntse tswj- tso tawm cov txheej txheem rau Ag+ ions kom ua tiav ob qho -txoj kev ua kom tsis muaj menyuam: ① kev cuam tshuam ntawm cov kab mob - yog li inducing cytoplasmic to; thiab ② nkag mus rau hauv lub cell membrane los cuam tshuam nrog DNA replication txheej txheem. Kev sim cov ntaub ntawv qhia tias nylon sportswear kho nrog Texnology FCG002 khaws cov * E. coli* inhibition tus nqi siab tshaj 98% txawm tias tom qab 100 kev lag luam ntxhua khaub ncaws, yog li ua tau raws li lub teb chaws AA- qib kev tu cev rau textiles.
2. Cov xwm txheej thov tshwj xeeb rau Photocatalytic Systems
Zinc oxide (ZnO) thiab titanium dioxide (TiO₂) photocatalysts cia siab rau ultraviolet (UV) lub teeb excitation los tsim reactive oxygen radicals, ua kom pom muaj zog inactivation muaj peev xwm tiv thaiv fungi xws li * Candida albicans *. Cov ntaub pua tsev kho mob coated nrog TiO₂- tsim los ntawm Toray Industries (Nyiv)- tau pom tias yuav txo tau txoj kev pheej hmoo ntawm tus kab mob hla - kis los ntawm 64% nyob rau hauv cov chaw kho mob hnyav (ICU) ib puag ncig. Txawm li cas los xij, lub fwj rau nws txoj kev lag luam yog nyob rau hauv qhov yuav tsum tau muaj rau 配套 LED ultraviolet irradiation system, uas tau txwv nws txoj kev saws me nyuam thoob plaws hauv lub tsev textile sector.
Ntuj Antimicrobial Agents: Ib qho Eco-Kev xaiv tus phooj ywg thiab sib txawv
1. Kev hloov tshiab tshiab ntawm tsob nroj- thiab tsiaj txhu-Drived Substances
Chitosan derivatives muab rho tawm los ntawm lub plhaub ntawm cw thiab crabs -ua raws li kev hloov kho ntawm sulfobetaine grafting- tuaj yeem siv los tsim cov txheej txheem tiv thaiv kab mob ruaj khov rau ntawm cov ntaub plaub fibers. Pab neeg tshawb fawb ntawm Sun Yat-sen University tau qhia tias, tom qab qhov kev kho mob no, kev sib cuag bacteriostatic ntev ntawm Merino wool sweaters tiv thaiv * Staphylococcus aureus * tau txuas ntxiv mus rau 72 teev, thaum lawv qhov ntsuas qhov ua pa tau zoo tuaj ntawm 18%. Lub caij no, tshuaj yej polyphenol rho tawm- ua los ntawm cov tshuaj tiv thaiv oxidation uas muaj quinone-zoo li cov qauv- nthuav dav pH buffering ntau yam ntawm ntuj- xim xyoob pulp pawm los npog 4.5-8.5 spectrum.
2. Ib qho Kev Tshaj Tawm Tshaj Tawm mus rau Multifunctional Composites
LG Chem (South Kaus Lim Qab Teb) tau qhia txog graphene-txhawb cov tshuaj tua kab mob uas cuam tshuam cov chitin molecular chains mus rau saum npoo ntawm ob- qhov ntev carbon lattice; Qhov kev tsim kho tshiab no tsis tsuas yog khaws cov biodegradability uas muaj nyob rau hauv cov ntaub ntawv ntuj tab sis kuj ua tiav kev tiv thaiv kev tiv thaiv tshuaj -resistant * Pseudomonas aeruginosa *. Kev sim kuaj pom tau tias Modal- cov ris tsho hauv qab fiber ntau kho nrog 0.3 wt% ntxiv ntawm cov khoom sib xyaw no khaws nws cov ntawv pov thawj AAA- qib tshuaj tiv thaiv kab mob txawm tias tom qab dhau 50 lub voj voog ntawm simulated tawm hws.
