Kuv pom tias cov cuab yeej siv tshuaj tua kab mob hauv kev kho mob li cas ua rau muaj qhov sib txawv. Cov kev daws teeb meem no txwv tsis pub cov kab mob microbes loj hlob ntawm qhov chaw zoo licov ntaub ntawv pov thawj dej, polyester viscose scrub ntaub, thiabTR spandex scrub ntaub. Cov txiaj ntsig hais rau lawv tus kheej:
| Hom kev cuam tshuam | Qhia Txog Kev Txom Nyem | Cov txiaj ntsig ntsuas |
|---|---|---|
| Copper oxide impregnated linens | 24% txo qis hauv HAIs rau 1000 hnub hauv tsev kho mob | Hospital-acquired infections (HAIs) |
| Copper-impregnated composite nyuaj nto thiab linens | 76% txo qis hauv HAIs | Hospital-acquired infections (HAIs) |

Ntsiab Cai
- Antimicrobial fabricssiv cov tshuaj tshwj xeeb xws li tooj liab, nyiaj, thiab tej yam ntuj tso los tiv thaiv cov kab mob tsis zoo los ntawm kev loj hlob hauv tsev kho mob khaub ncaws thiab txaj.
- Cov ntaub no tseem muaj txiaj ntsig txawm tias tom qab ntxuav ntau thiab ua kom tsis muaj menyuam, pab txo cov kab mob thiab ua kom cov neeg mob thiab cov neeg ua haujlwm nyab xeeb dua.
- Siv cov ntaub ntawv kho mob los tiv thaiv kab mob txhawb nqa tsev kho mob kom huv, txo qis tus kab mob, thiab muaj kev nyab xeeb, zoo rau cov tawv nqaij uas tiv thaiv tib neeg thiab ib puag ncig.
Mechanisms thiab Science ntawm Antimicrobial Healthcare Fabric
Hom Antimicrobial Agents
Thaum kuv saib kev tshawb fawb tom qab kev kho mob ntaub, kuv pom ntau yamtshuaj tua kab mobtom haujlwm. Txhua tus neeg sawv cev siv ib txoj kev tshwj xeeb los nres lossis tua cov kab mob phem. Ntawm no yog ib lub rooj uas qhia cov neeg sawv cev tshaj plaws, lawv ua haujlwm li cas, thiab cov fibers twg lawv kho:
| Antimicrobial Agent | Hom Kev Ua Haujlwm | Hom Fibers siv |
|---|---|---|
| Chitosan | Inhibits mRNA synthesis thiab blocks thauj cov ntsiab lus tseem ceeb | Paj rwb, polyester, ntaub plaub |
| Hlau thiab hlau ntsev (xws li, nyiaj, tooj liab, zinc oxide, titanium nanoparticles) | Generates reactive oxygen hom; ua rau cov protein, lipids, DNA puas | Paj rwb, polyester, nylon, ntaub plaub |
| N-halamine | cuam tshuam nrog cellular enzymes thiab cov txheej txheem metabolic | Paj rwb, polyester, nylon, ntaub plaub |
| Polyhexamethylene Biguanide (PHMB) | Disrupts cell membrane kev ncaj ncees | Paj Rwb, Polyester, Nylon |
| Quaternary Ammonium Compounds | Ua kom puas cell membranes, denatures proteins, inhibits DNA synthesis | Paj rwb, polyester, nylon, ntaub plaub |
| Triclosan | Blocks lipid synthesis thiab cuam tshuam cov cell membrane | Polyester, Nylon, Polypropylene, Cellulose Acetate, Acrylic |
Kuv feem ntau pom cov hlau xws li nyiaj thiab tooj liab siv hauv tsev kho mob khaub ncaws thiab txaj. Cov neeg ua haujlwm no pab txo qis kev kis kab mob thiab cov kab mob hauvkho mob ntaub. Quaternary ammonium compounds thiab chitosan kuj tshwm sim nyob rau hauv ntau yam khoom rau cov neeg mob thiab cov kws kho mob.
Nco tseg:Cov qauv ntsuas xws li AATCC 100, ISO 20743, thiab ASTM E2149 pab ntsuas seb cov neeg ua haujlwm no ua haujlwm zoo li cas hauv qhov chaw tiag tiag.
Yuav ua li cas cov neeg sawv cev cuam tshuam kev loj hlob ntawm microbial
Kuv pom tias cov tshuaj tiv thaiv kab mob siv ntau lub tswv yim los tiv thaiv cov kab mob microbes los ntawm kev loj hlob ntawm daim ntaub kho mob. Nov yog qee qhov tseem ceeb ntawm cov neeg ua haujlwm no ua haujlwm:
- Lawv tua cov phab ntsa ntawm tes los yog daim nyias nyias ntawm cov kab mob, ua rau lub hlwb tawg los yog xau.
- Qee cov neeg ua haujlwm, zoo li nyiaj nanoparticles, tso tawm ions uas cuam tshuam cov protein thiab DNA hauv microbe.
- Lwm tus, xws li chitosan, thaiv cov microbe lub peev xwm los ua cov proteins tshiab lossis thauj cov khoom noj.
- Qee tus neeg ua haujlwm tsim cov pa oxygen reactive uas ua rau cov khoom tseem ceeb ntawm cov microbe puas tsuaj, ua rau lub cell tuag.
- Enzyme-based kev kho mob tuaj yeem rhuav tshem cov txheej txheem tiv thaiv kab mob, ua rau lawv tua tau yooj yim dua.
Kev kuaj kuaj pom tseeb tias cov kev ua no. Piv txwv li, kuv tau pom cov kev tshawb fawb qhov twg fabrics kho nrog nyiaj los yog zinc oxide nanoparticles qhia muaj zog tiv thaiv kab mob xws li E. coli thiab Staphylococcus aureus. Cov kws tshawb fawb siv cov cuab yeej xws li scanning electron microscopy los xyuas tias cov neeg ua haujlwm no nyob nrog rau cov ntaub thiab ua haujlwm tom qab ntxuav. Cov kev ntsuam xyuas tus qauv, xws li los ntawm American Association of Textile Chemists thiab Colorists, pab xyuas ob qho tib si lub zog thiab ua haujlwm ntev ntawm cov kev kho mob no.
Efficiency thiab Durability
Kuv ib txwm saib cov ntaub ntawv kho mob uas ua haujlwm tom qab siv ntau thiab ntxuav. Cov kev kho mob antimicrobial zoo tshaj plaws qhia tau hais tias muaj txiaj ntsig zoo tiv thaiv ntau yam kab mob, txawm tias tom qab ua kom tsis muaj menyuam. Cov lus hauv qab no qhia tias cov neeg ua haujlwm sib txawv ua ntej thiab tom qab ua kom tsis muaj menyuam:
| Antimicrobial Agent | BR tiv thaiv E. coli (%) | BR tiv thaiv K. pneumoniae (%) | BR tiv thaiv MRSA (%) | BR tom qab Sterilization tiv thaiv E. coli (%) | BR tom qab Sterilization tiv thaiv K. pneumoniae (%) | BR tom qab Sterilization tiv thaiv MRSA (%) |
|---|---|---|---|---|---|---|
| Nyiaj nitrate | 99.87 ib | 100 | 84.05 ib | 97.67 ib | 100 | 24.35 Nws |
| Zinc chloride | 99.87 ib | 100 | 99.71 ib | 99.85 ib | 100 | 97.83 ib |
| HM4005 (QAC) | 99.34 ib | 100 | 0 | 65.78 ib | 0 | 36.03 Nws |
| HM4072 (QAC) | 72.18 Nws | 98.35 ib | 25.52 Nws | 0 | 21.48 Nws | 0 |
| Tshuaj yej tsob ntoo roj | 100 | 100 | 99.13 ib | 100 | 97.67 ib | 23.88 Nws |
Kuv pom tias zinc chloride thiab nyiaj nitrate khaws lawv lub zog tiv thaiv kab mob txawm tias tom qab cua sov kom tsis muaj menyuam. Tshuaj yej tsob ntoo roj kuj ua haujlwm zoo, tab sis qee cov neeg ua haujlwm, zoo li qee cov quaternary ammonium compounds, poob ntau ntawm lawv cov txiaj ntsig tom qab ua kom tsis muaj menyuam. Cov kev tshawb fawb mus sij hawm ntev qhia tau hais tias cov coatings nrog tooj liab oxide thiab graphene oxide tuaj yeem tua cov kab mob mus txog rau lub hlis. Hauv ib txoj kev tshawb fawb, cov ntaub ntawv kho mob no tau khaws ntau dua 96% kev ua tau zoo ntawm E. coli tom qab siv ib nrab xyoo.
Kev sim tshuaj kho mob rov qab tau cov kev tshawb pom no. Piv txwv li, lub tsev kho mob hauv ncoo thiab cov ntaub ntawv coated nrog cov tshuaj tua kab mob khaws cov kab mob hauv qab cov qauv kev tu cev tom qab siv ib lub lim tiam. Cov txiaj ntsig no qhia tau tias txoj kev kho tshuaj tua kab mob tuaj yeem ua rau cov ntaub ntawv kho mob muaj kev nyab xeeb thiab txhim khu kev qha rau cov neeg mob thiab cov neeg ua haujlwm.
