Asayansi ku De Montfort University (DMU) ku Leicester adachenjeza kuti kachilombo kofanana ndi komwe kamayambitsa Covid-19 katha kukhala ndi moyo pa zovala ndikufalikira kumalo ena kwa maola 72.
Mu kafukufuku wofufuza momwe kachilombo ka corona kamachitira pa mitundu itatu ya nsalu zomwe zimagwiritsidwa ntchito kwambiri mumakampani azaumoyo, ofufuza adapeza kuti zotsalirazo zimatha kukhalabe zopatsirana kwa masiku atatu.
Motsogozedwa ndi katswiri wa tizilombo toyambitsa matenda Dr. Katie Laird, katswiri wa tizilombo Dr. Maitreyi Shivkumar, ndi katswiri wofufuza za matenda a postdoctoral Dr. Lucy Owen, kafukufukuyu akuphatikizapo kuwonjezera madontho a kachilombo ka corona kotchedwa HCoV-OC43, komwe kapangidwe kake ndi momwe moyo wake ulili wofanana ndi wa SARS-CoV-2, zomwe zimapangitsa kuti pakhale Covid-19-polyester, thonje la polyester ndi thonje 100%.
Zotsatira zake zikusonyeza kuti polyester ndiye chiopsezo chachikulu chofalitsa kachilomboka. Kachilombo koyambitsa matendawa kamakhalapobe patatha masiku atatu ndipo kakhoza kusamutsidwira kumalo ena. Pa thonje 100%, kachilomboka kamakhalapo kwa maola 24, pomwe pa thonje la polyester, kachilomboka kamapulumuka kwa maola 6 okha.
Dr. Katie Laird, mtsogoleri wa DMU Infectious Disease Research Group, anati: “Pamene mliriwu unayamba, panalibe zambiri zodziwika bwino zokhudza nthawi yomwe kachilombo ka corona kangathe kukhalapo pa nsalu.”
"Zomwe tapeza zikusonyeza kuti nsalu zitatu zomwe zimagwiritsidwa ntchito kwambiri pazachipatala zili pachiwopsezo chofalitsa kachilomboka. Ngati anamwino ndi ogwira ntchito zachipatala atenga yunifolomu yawo kupita nayo kunyumba, angasiye zotsalira za kachilomboka pamalo ena."
Chaka chatha, poyankha mliriwu, Public Health England (PHE) idapereka malangizo onena kuti mayunifolomu a ogwira ntchito zachipatala ayenera kutsukidwa m'mafakitale, koma ngati sizingatheke, ogwira ntchito ayenera kutenga mayunifolomuwo kupita nawo kunyumba kuti akatsukidwe.
Nthawi yomweyo, malangizo a NHS Uniform ndi Workwear Guidelines amanena kuti ndikotetezeka kutsuka yunifolomu ya ogwira ntchito zachipatala kunyumba bola ngati kutentha kwake kuli kochepera 60°C.
Dr. Laird akuda nkhawa kuti umboni wochirikiza mawu omwe ali pamwambapa ukuchokera makamaka pa ndemanga ziwiri zakale za mabuku zomwe zinasindikizidwa mu 2007.
Poyankha, iye adapereka lingaliro lakuti mayunifolomu onse azachipatala a boma ayeretsedwe m'zipatala mogwirizana ndi miyezo yamalonda kapena ndi malo ochapira zovala m'mafakitale.
Kuyambira nthawi imeneyo, wafalitsanso ndemanga yatsopano komanso yokwanira ya mabuku, kuwunika kuopsa kwa nsalu pakufalikira kwa matenda, ndikugogomezera kufunika kwa njira zowongolera matenda pogwira ntchito ndi nsalu zachipatala zodetsedwa.
"Pambuyo pa kuwunika mabuku, gawo lotsatira la ntchito yathu ndikuwunika zoopsa zopewera matenda poyeretsa mayunifolomu azachipatala omwe ali ndi kachilombo ka corona," adatero. "Tikangodziwa kuchuluka kwa kupulumuka kwa kachilombo ka corona pa nsalu iliyonse, tidzayang'ana kwambiri pakupeza njira yodalirika kwambiri yotsukira kachilomboka."
Asayansi amagwiritsa ntchito thonje 100%, nsalu yogwiritsidwa ntchito kwambiri pa thanzi, kuti achite mayeso angapo pogwiritsa ntchito kutentha kosiyanasiyana kwa madzi ndi njira zotsukira, kuphatikizapo makina ochapira m'nyumba, makina ochapira m'mafakitale, makina ochapira m'zipatala zamkati, ndi njira yoyeretsera ya ozone (mpweya wochuluka).
Zotsatira zake zinasonyeza kuti mphamvu ya kusakaniza madzi inali yokwanira kuchotsa mavairasi m'makina onse ochapira omwe anayesedwa.
Komabe, pamene gulu lofufuza linaipitsa nsalu ndi malovu opangidwa okhala ndi kachilomboka (kuti ayerekezere chiopsezo chofalikira kuchokera mkamwa mwa munthu wodwala), adapeza kuti makina ochapira m'nyumba sanachotse kachilomboka konse, ndipo zotsalira zina zinapulumuka.
Pokhapokha akawonjezera sopo ndikukweza kutentha kwa madzi, kachilomboka kamatheratu. Pofufuza momwe kachilomboka kamakanira kutentha kokha, zotsatira zake zikuwonetsa kuti kachilombo ka corona kali kokhazikika m'madzi mpaka 60°C, koma kamatha kugwira ntchito pa 67°C.
Kenako, gululo linaphunzira za chiopsezo cha kufalikira kwa kachilomboka, kutsuka zovala zoyera ndi zovala zokhala ndi zizindikiro za kachilomboka pamodzi. Anapeza kuti makina onse oyeretsera anali atachotsa kachilomboka, ndipo panalibe chiopsezo chakuti zinthu zina ziipitsidwe.
Dr. Laird anafotokoza kuti: “Ngakhale kuti tingaone kuchokera mu kafukufuku wathu kuti ngakhale kutsuka zinthuzi kutentha kwambiri mu makina ochapira apakhomo kungathe kuchotsa kachilomboka, sikuchotsa chiopsezo cha zovala zodetsedwa zomwe zimasiya zizindikiro za kachilombo ka corona pamalo ena. Zisanatsukidwe kunyumba kapena mgalimoto.
"Tsopano tikudziwa kuti kachilomboka kakhoza kukhalapo mpaka maola 72 pa nsalu zina, ndipo kangathenso kusamutsidwira ku malo ena."
"Kafukufukuyu akulimbitsa lingaliro langa lakuti mayunifolomu onse azachipatala ayeretsedwe pamalopo m'zipatala kapena m'zipinda zotsukira zovala zamafakitale. Njira zotsukirazi zimayang'aniridwa, ndipo anamwino ndi ogwira ntchito zachipatala sayenera kuda nkhawa ndi kubweretsa kachilomboka kunyumba."
Akatswiri ena ofalitsa nkhani akuchenjeza kuti mayunifolomu azachipatala sayenera kutsukidwa kunyumba panthawi ya mliriwu. Kafukufuku akusonyeza kuti njira zotsukira ozone zimatha kuchotsa kachilombo ka corona m'zovala. Kafukufuku akusonyeza kuti choko chokwera sichingafalitse kachilombo ka corona.
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.
"Yankho linali labwino kwambiri," adatero Dr. Laird. "Mabungwe osamalira nsalu ndi zovala padziko lonse lapansi tsopano akugwiritsa ntchito mfundo zofunika kwambiri mu malangizo athu osamalira ndalama kuti apewe kufalikira kwa kachilombo ka corona."
David Stevens, mkulu wa bungwe la British Textile Services Association, lomwe ndi bungwe la zamalonda la makampani osamalira nsalu, anati: “Pa nthawi ya mliriwu, tikumvetsa bwino kuti nsalu sizomwe zimayambitsa matenda a coronavirus.
"Komabe, sitikudziwa zambiri zokhudza kukhazikika kwa mavairasi awa m'mitundu yosiyanasiyana ya nsalu ndi njira zosiyanasiyana zotsukira. Izi zapangitsa kuti pakhale mfundo zina zabodza komanso malangizo ochulukirapo okhudza kutsuka."
"Taganizira mwatsatanetsatane njira ndi njira zofufuzira zomwe Dr. Laird ndi gulu lake amagwiritsa ntchito, ndipo tapeza kuti kafukufukuyu ndi wodalirika, wobwerezabwereza komanso wobwerezabwereza. Kutsiriza kwa ntchito iyi yochitidwa ndi DMU kumalimbitsa gawo lofunika kwambiri la kuwongolera kuipitsa chilengedwe - kaya m'nyumba mudakali m'malo opangira mafakitale."
Pepala lofufuzirali lasindikizidwa mu Open Access Journal of the American Society for Microbiology.
Pofuna kuchita kafukufuku wowonjezereka, gululi linagwirizananso ndi gulu la zamaganizo la DMU ndi chipatala cha Leicester NHS Trust University Hospital pa ntchito yofufuza chidziwitso ndi malingaliro a anamwino ndi ogwira ntchito zachipatala pa kuyeretsa yunifolomu panthawi ya mliri wa Covid-19.
