Masayendisiti epaDe Montfort University (DMU) kuLeicester akayambira kuti hutachiona hwakafanana nehosha inokonzeresa Covid-19 hunogona kurarama pachipfeko uye huchipararira kune dzimwe nzvimbo kwemaawa anosvika makumi manomwe nemaviri.
Muchidzidzo chekuongorora maitiro eiyo coronavirus pamhando nhatu dzemachira anowanzo shandiswa muindasitiri yezvehutano, vaongorori vakawana kuti maronda anogona kuramba achitapukira kwemazuva matatu.
Pasi pehutungamiriri hwe microbiologist Dr. Katie Laird, virologist Dr. Maitreyi Shivkumar, uye postdoctoral muongorori Dr. Lucy Owen, tsvagiridzo iyi inosanganisira kuwedzera madonhwe emhando yekoronavirus inonzi HCoV-OC43, ine chimiro uye mararamiro akafanana neaya eSARS- CoV-2 yakafanana zvakanyanya, inotungamira kuCovid-19-polyester, polyester donje uye 100% donje.
Mhedzisiro yacho inoratidza kuti polyester ndiyo yakanyanya njodzi yekuparadzira hutachiona.Utachiona hwehutachiona huchiripo mushure memazuva matatu uye hunogona kuendeswa kune dzimwe nzvimbo.Pa100% donje, hutachiona hunogara kwemaawa makumi maviri nemana, nepo pa polyester donje, hutachiona hunorarama kwemaawa matanhatu chete.
Dr. Katie Laird, mukuru weDMU Infectious Disease Research Group, akati: “Pakatanga denda iri, zvishoma zvaizivikanwa nezvekuti coronavirus inogona kurarama kwenguva yakareba sei pamicheka.”
“Zvatakawana zvinoratidza kuti machira matatu anonyanya kushandiswa munyaya dzehutano ari panjodzi yekuparadzira utachiona uhu.Kana vanamukoti nevashandi vekurapa vakatora mayunifomu avo kumba, vanogona kusiya hutachiona pane dzimwe nzvimbo. ”
Gore rapfuura, vachipindura denda iri, Public Health England (PHE) yakapa nhungamiro inotaura kuti mayunifomu evashandi vekurapa anofanirwa kucheneswa mumaindasitiri, asi pazvisingaite, vashandi vanofanirwa kuendesa mayunifomu kumba kunocheneswa.
Panguva imwe cheteyo, NHS Uniform and Workwear Guidelines inoti hazvina njodzi kuchenesa mayunifomu evashandi vezvokurapa kumba chero tembiricha yakadzikwa kusvika pa60°C.
Dr. Laird anonetsekana kuti uchapupu hunotsigira zvataurwa pamusoro apa hunonyanya kubva pakuongorora mabhuku maviri ekare akabudiswa muna 2007.
Mukupindura, akataura kuti mayunifomu ese ehurumende ekurapa anofanirwa kucheneswa muzvipatara zvinoenderana netsika dzekutengesa kana nekuwacha maindasitiri.
Kubva ipapo, akaburitsa ongororo yakagadziridzwa uye yakazara mabhuku, achiongorora njodzi yemachira mukupararira kwezvirwere, uye achisimbisa kukosha kwemaitiro ekudzivirira kutapukira kana uchibata machira akasvibiswa ekurapa.
"Mushure mekuongorora kwemabhuku, nhanho inotevera yebasa redu ndeyekuongorora njodzi dzekudzora hutachiona dzekuchenesa yunifomu yekurapa yakasvibiswa nekoronavirus," akaenderera mberi."Kana tangoona huwandu hwekupona kwekoronavirus pamachira ega ega, isu tichaisa pfungwa dzedu pakuona nzira yakavimbika yekugeza kubvisa hutachiona."
Masayendisiti anoshandisa 100% donje, iyo inonyanya kushandiswa yehutano machira, kuita bvunzo dzakawanda vachishandisa dzakasiyana tembiricha yemvura uye nzira dzekuwacha, kusanganisira michina yekuwachisa yemumba, michina yekuwachisa maindasitiri, michina yekuwachisa yemukati yechipatara, uye ozone (gasi rinonyanya kuita basa) yekuchenesa system.
Mhedzisiro yacho yakaratidza kuti kubvongodza uye dilution mhedzisiro yemvura yaive yakakwana kubvisa mavhairasi mumichina yese yekuwachisa yakaedzwa.
Nekudaro, apo boka rekutsvagisa rakasvibisa micheka nemate ekugadzira ane hutachiona (kufananidza njodzi yekutapuriranwa kubva mumuromo wemunhu ane hutachiona), vakaona kuti michina yekuwachisa yemumba haina kubvisa zvachose hutachiona, uye mamwe maitiro akapona.
Chete pavanowedzera detergent uye kusimudza tembiricha yemvura, hutachiona hunopedzwa zvachose.Kuongorora kupikisa kwehutachiona kupisa chete, mhedzisiro yakaratidza kuti coronavirus yakagadzikana mumvura inosvika 60 ° C, asi haina inactivated pa67 ° C.
Zvadaro, boka racho rakaongorora njodzi yekutapukirwa, kuwacha mbatya dzakachena nembatya dzine utachiona pamwe chete.Vakaona kuti masisitimu ese ekuchenesa akange abvisa hutachiona, uye pakanga pasina njodzi yekuti zvimwe zvinhu zvakasvibiswa.
Dr. Laird vakatsanangura kuti: “Kunyangwe tichiona kubva mukutsvagisa kwedu kuti kunyangwe kugeza-tembiricha kwezvinhu izvi mumushini wekuwachisa wemba kunogona kubvisa hutachiona, hazvibvise njodzi yembatya dzine utachiona zvichisiya zvisaririra zvekoronavirus pane dzimwe nzvimbo. .Vasati vagezeswa kumba kana mumota.
"Isu tave kuziva kuti hutachiona hunogona kurarama kusvika maawa makumi manomwe nemaviri pane mamwe machira, uye hunogona kutamiswa kune dzimwe nzvimbo.
“Ongororo iyi inosimbisa kurudziro yangu yekuti mayunifomu ese ekurapa anofanirwa kucheneswa panzvimbo muzvipatara kana mudzimba dzekuwachira dzemaindasitiri.Nzira dzekuchenesa idzi dzinotariswa, uye vanamukoti nevashandi vezvokurapa havafanirwe kunetseka nezvekuunza hutachiona kumba. ”
Nyanzvi dzenhau dzakafanana dzinoyambira kuti yunifomu yekurapa haifanirwe kucheneswa kumba panguva yedenda.Tsvagiridzo inoratidza kuti ozone yekuchenesa masisitimu anogona kubvisa coronavirus kubva muzvipfeko.Tsvagiridzo inoratidza kuti kukwira choko hakugone kuparadzira coronavirus.
Nerutsigiro rweBritish Textile Trade Association, Dr. Laird, Dr. Shivkumar naDr. Owen vakagovera zvavakawana nenyanzvi dzemaindasitiri muUnited Kingdom, United States neEurope.
“Mhinduro yacho yakanga yakanaka zvikuru,” Dr. Laird akadaro."Masangano ezvipfeko nekuwachira pasirese ave kuita ruzivo rwakakosha muhutano hwedu hwekubiridzira mari nhungamiro kudzivirira kupararira kwegoronavirus."
David Stevens, mukuru mukuru weBritish Textile Services Association, mubatanidzwa wemachira ekuchengetedza indasitiri, akati: "Mumamiriro ezvinhu edenda, tine nzwisiso yekuti machira handiwo anonyanya kutapurirana hutachiona.
“Zvisinei, isu tinoshaya ruzivo nezve kugadzikana kwehutachiona uhu mumhando dzakasiyana dzemachira uye nzira dzakasiyana dzekuwacha.Izvi zvakonzera kuti mamwe mashoko asiri iwo atenderere uye nekuwacha kurudziro yakawandisa.
“Takaongorora zvakadzama nzira nemaitirwo etsvakurudzo akashandiswa naDr. Laird nechikwata chake, uye takaona kuti tsvakiridzo iyi yakavimbika, inogona kudhindwa uye inogona kudhindwa.Mhedziso yebasa iri rakaitwa neDMU inosimbisa basa rakakosha rekudzora kusvibiswa-kungave muImba ichiri munzvimbo yeindasitiri. "
Bepa rekutsvagisa rakaburitswa muOpen Access Journal yeAmerican Society yeMicrobiology.
Kuti tiite imwe tsvagiridzo, timu zvakare yakabatana nechikwata cheDMU chepfungwa uye Leicester NHS Trust University Hospital pachirongwa chekuongorora ruzivo nemafungiro evanamukoti nevashandi vekurapa pakuchenesa mayunifomu panguva yeCovid-19 denda.
