Asayansi a pa yunivesite ya De Montfort (DMU) ku Leicester anachenjeza kuti kachilombo kofanana ndi kupsyinjika komwe kumayambitsa Covid-19 kumatha kukhala ndi zovala ndikufalikira kumalo ena mpaka maola 72.
Pakafukufuku wowunika momwe ma coronavirus amachitira pamitundu itatu ya nsalu zomwe zimagwiritsidwa ntchito kwambiri m'makampani azachipatala, ofufuza adapeza kuti zomwe zidachitikazi zimatha kukhala zopatsirana mpaka masiku atatu.
Motsogozedwa ndi katswiri wa sayansi ya tizilombo Dr. Katie Laird, katswiri wa tizilombo Dr. Maitreyi Shivkumar, ndi wofufuza wa postdoctoral Dr. Lucy Owen, kafukufukuyu akuphatikizapo kuwonjezera madontho amtundu wa coronavirus wotchedwa HCoV-OC43, omwe mawonekedwe ake ndi njira zopulumutsira ndizofanana ndi za SARS- CoV-2 ndiyofanana kwambiri, zomwe zimatsogolera ku Covid-19-polyester, thonje la polyester ndi thonje 100%.
Zotsatira zikuwonetsa kuti polyester ndiye pachiwopsezo chachikulu chofalitsa kachilomboka.Kachilombo ka kachilomboka kamakhalabe pakadutsa masiku atatu ndipo amatha kusamutsidwa kumalo ena.Pa thonje la 100%, kachilomboka kamakhala kwa maola 24, pomwe pa thonje la polyester, kachilomboka kamangokhala ndi moyo kwa maola 6.
Dr. Katie Laird, wamkulu wa bungwe la DMU Infectious Disease Research Group, anati: “Mliriwu utangoyamba, panalibe zambiri zomwe zinkadziwika kuti kachilomboka kamatha kukhalabe ndi nsalu kwa nthawi yayitali bwanji.
"Zomwe tapeza zikuwonetsa kuti nsalu zitatu zomwe zimagwiritsidwa ntchito kwambiri pazachipatala zili pachiwopsezo chofalitsa kachilomboka.Anamwino ndi ogwira ntchito zachipatala akatenga yunifolomu yawo kunyumba, amatha kusiya kachilomboka pamalo ena. ”
Chaka chatha, pothana ndi mliriwu, Public Health England (PHE) idapereka malangizo onena kuti yunifolomu ya ogwira ntchito zachipatala iyenera kutsukidwa m'mafakitale, koma komwe sikungatheke, ogwira ntchitowo azitengera yunifolomuyo kunyumba kuti akayeretse.
Panthawi imodzimodziyo, NHS Uniform and Workwear Guidelines imati ndi bwino kuyeretsa yunifolomu ya ogwira ntchito zachipatala kunyumba malinga ngati kutentha kuli kochepera 60 ° C.
Dr. Laird akuda nkhawa kuti umboni wotsimikizira mawu omwe ali pamwambawa makamaka umachokera ku ndemanga ziwiri zachikale za mabuku zomwe zinasindikizidwa mu 2007.
Poyankha, adanenanso kuti mayunifolomu onse aboma azachipatala aziyeretsedwa m'zipatala motsatira miyezo yamalonda kapena ndi zovala zamakampani.
Kuyambira nthawi imeneyo, adasindikizanso zolemba zosinthidwa komanso zatsatanetsatane, ndikuwunika kuopsa kwa nsalu pakufalikira kwa matenda, ndikugogomezera kufunikira kwa njira zopewera matenda pogwira nsalu zachipatala zomwe zaipitsidwa.
"Pambuyo powerenga mabuku, gawo lotsatira la ntchito yathu ndikuwunika kuopsa kwa matenda otsuka mayunifolomu azachipatala omwe ali ndi coronavirus," adapitilizabe."Tikangodziwa kuchuluka kwa kupulumuka kwa ma coronavirus pansalu iliyonse, titembenukira kuti tipeze njira yodalirika yotsuka yochotsera kachilomboka."
Asayansi amagwiritsa ntchito thonje 100%, nsalu zathanzi zomwe zimagwiritsidwa ntchito kwambiri, kuyesa kangapo pogwiritsa ntchito kutentha kwamadzi ndi njira zochapira zosiyanasiyana, kuphatikiza makina ochapira m'nyumba, makina ochapira a mafakitale, makina ochapira m'zipatala, ndi ozone (gasi wothamanga kwambiri).
Zotsatira zinawonetsa kuti kusonkhezera ndi kusungunuka kwa madzi kunali kokwanira kuchotsa mavairasi m'makina onse ochapira oyesedwa.
Komabe, pamene gulu lofufuza lidadetsa nsalu ndi malovu ochita kupanga okhala ndi kachilomboka (kutengera kuopsa kwa kufalikira kuchokera mkamwa mwa munthu yemwe ali ndi kachilomboka), adapeza kuti makina ochapira m'nyumba sanachotseretu kachilomboka, ndipo zida zina zidapulumuka.
Pokhapokha atawonjezera zotsukira ndikukweza kutentha kwa madzi, kachilomboka kamafafanizidwa.Pofufuza kukana kwa kachilomboka kutenthedwa kokha, zotsatira zake zidawonetsa kuti coronavirus imakhala yokhazikika m'madzi mpaka 60 ° C, koma imayikidwa pa 67 ° C.
Kenako, gululo linaphunzira za chiopsezo chotenga kachilomboka, kuchapa zovala zaukhondo ndi zovala zokhala ndi kachilomboka.Adapeza kuti njira zonse zoyeretsera zidachotsa kachilomboka, ndipo panalibe chiwopsezo choti zinthu zina zitha kuipitsidwa.
Dr. Laird adalongosola kuti: “Ngakhale kuti titha kuwona kuchokera mu kafukufuku wathu kuti ngakhale kutsuka kotentha kwambiri kwa zinthuzi m'makina ochapira m'nyumba kumatha kuchotsa kachilomboka, sikuchotsa chiwopsezo cha zovala zomwe zili ndi kachilombo kosiya ma coronavirus pamalo ena. .Asanasambitsidwe kunyumba kapena mgalimoto.
"Tsopano tikudziwa kuti kachilomboka kamatha kukhala ndi moyo mpaka maola 72 pansalu zina, ndipo amathanso kusamutsidwa kumalo ena.
“Kafukufukuyu akulimbitsa malingaliro anga oti mayunifolomu onse azachipatala aziyeretsedwa pamalo omwe ali m’zipatala kapena m’zipinda zochapira za mafakitale.Njira zoyeretserazi zimayang'aniridwa, ndipo anamwino ndi ogwira ntchito zachipatala sayenera kuda nkhawa kuti abweretse kachilomboka kunyumba. ”
Akatswiri ankhani zokhudzana ndi izi akuchenjeza kuti zovala zachipatala siziyenera kutsukidwa kunyumba panthawi ya mliri.Kafukufuku akuwonetsa kuti makina oyeretsera ozoni amatha kuchotsa zovala za coronavirus.Kafukufuku akuwonetsa kuti kukwera choko ndikokayikitsa kufalitsa coronavirus.
Mothandizidwa ndi British Textile Trade Association, Dr. Laird, Dr. Shivkumar ndi Dr. Owen adagawana zomwe adapeza ndi akatswiri amakampani ku United Kingdom, United States ndi Europe.
"Kuyankha kunali kolimbikitsa kwambiri," adatero Dr. Laird."Mabungwe ovala zovala ndi zovala padziko lonse lapansi tsopano akugwiritsa ntchito zidziwitso zofunika pazaumoyo wathu kuti tipewe kufalikira kwa coronavirus."
A David Stevens, wamkulu wa bungwe la British Textile Services Association, bungwe lazamalonda losamalira zovala, adati: "Pavutoli, tikumvetsetsa kuti nsalu sizomwe zimafalitsa ma coronavirus.
"Komabe, sitidziwa zambiri za kukhazikika kwa ma virus awa mumitundu yosiyanasiyana ya nsalu ndi njira zosiyanasiyana zochapira.Izi zapangitsa kuti zidziwitso zina zabodza ziziyandama komanso malingaliro ochapa kwambiri.
"Tapenda mwatsatanetsatane njira ndi njira zofufuzira zomwe Dr. Laird ndi gulu lake adagwiritsa ntchito, ndipo tapeza kuti kafukufukuyu ndi wodalirika, wokhoza kupanga komanso wokhoza kupanga.Mapeto a ntchito iyi yochitidwa ndi DMU ilimbitsa gawo lofunikira la kuwononga chilengedwe-kaya ku Nyumbayo kudakali m'malo opangira mafakitale. "
Pepala lofufuzira lasindikizidwa mu Open Access Journal ya American Society for Microbiology.
Kuti achite kafukufuku wopitilira, gululi lidalumikizananso ndi gulu la psychology la DMU komanso chipatala cha Leicester NHS Trust University pa ntchito yofufuza zomwe anamwino komanso ogwira ntchito pachipatala akuzindikira komanso momwe amaonera mayunifolomu pa nthawi ya mliri wa Covid-19.
