Abaphenyi eNyuvesi yaseGeorgia benze into entsha enezakhiwo ezilungele imishini yezokwelapha enjengamamaski namabhandeshi. Iphinde ibe nobungane kakhulu kwimvelo kunezinto ezisetshenziswayo njengamanje.
Lisebenzisa ama-nonwovens (izindwangu ezenziwe ngokuhlanganisa imicu ngaphandle kokwelukwa noma ukunithwa), ithimba eliholwa nguGajanan Bhat likwazile ukwenza izinto eziyinhlanganisela eziguquguqukayo, eziphefumulayo nezimuncayo ezilungele izinsiza zezokwelapha. Ukufakwa kukakotini nakho kwenza izinto eziwumphumela zikhululeke esikhunjeni (isici esibalulekile ngezinjongo zezokwelapha) futhi kube lula ukwenza umquba, okwenza kube nobungane bemvelo kunemikhiqizo efanayo emakethe njengamanje.

Ngoxhaso lwe-USDA, abacwaningi bahlole inhlanganisela ehlukahlukene yekotini nama-nonwovens, kanye nama-nonwovens asekuqaleni, ngezakhiwo ezifana nokuphefumula, ukumuncwa kwamanzi kanye nokunwebeka. Izindwangu ezihlanganisiwe zenze kahle ekuhlolweni, zinikeza ukuphefumula okuhle, ukumunca amanzi kakhulu kanye nokululama okuhle, okusho ukuthi zingakwazi ukumelana nokusetshenziswa okuphindaphindiwe.
Isidingo sama-nonwovens besikhula eminyakeni yamuva nje, futhi inani lemakethe kulindeleke ukuthi lifinyelele ku-US $ 77 billion ngo-2027, ngokusho kombiko we-Acumen Research and Consulting. Ama-nonwovens asetshenziswa kakhulu emikhiqizweni yasendlini njengamanabukeni, imikhiqizo yenhlanzeko yabesifazane, nezihlungi zomoya namanzi. Azikwazi ukungena emanzini, ziyavumelana nezimo, ziyaphefumula, futhi ikhono lazo lokuhlunga umoya lizenza zilungele ukusetshenziswa kwezokwelapha.
"Eminye yale mikhiqizo esetshenziselwa izinhloso ze-biomedical, njengama-patches nama-bandages, idinga ukwelula nokululama ngemva kokwelula. Kodwa ngenxa yokuthi ihlangana nomzimba, ukusebenzisa ukotini kungaba yinzuzo ngempela, kusho i-Family and Consumer College. Izinsizakalo zathi uBarth, usihlalo woMnyango Wezindwangu, Ukuthengiswa Kwempahla kanye Nokwakhiwa Kwangaphakathi, owabhala ngokuhlanganyela iphepha nomfundi we-Partfirhak no-Studar D. Shafiqul Islam.
Nakuba ukotini awunwebeki njengendwangu engalukiwe, uyamunca futhi uthambile, okwenza kube lula ukuwugqoka. Ukotini uyisilimo esikhulu eGeorgia futhi uyingxenye ebalulekile yomnotho wezwe. I-USDA ihlale ibheka ukusetshenziswa okusha kukakotini, futhi u-Barth uphakamise ukuthi “bahlanganise ama-nonwovens anwebekayo nokotini ukuze bakhe okuthile okuphakeme kunokotini nokunwebekayo.”

U-Barth, osebenza kakhulu kuma-nonwovens, ukholelwa ukuthi into ewumphumela ingagcina izici ezifiselekayo zama-nonwovens kuyilapho kuba lula ukuyiphatha futhi ivundiswe.
Ukuhlola izici zenhlanganisela, i-Bhat, i-Sikdar ne-Islam ihlanganise ukotini nezinhlobo ezimbili zama-nonwovens: i-spunbond ne-meltblown. Ama-nonwovens e-Spunbond aqukethe imicu eqinile futhi ngokuvamile ayakwazi ukuqina, kuyilapho ama-nonwovens ancibilikayo ancibilikayo aqukethe imicu ecolekile futhi anezakhiwo ezingcono zokuhlunga.
“Umbono wawuwukuthi, ‘Iyiphi inhlanganisela ezosinika imiphumela emihle?’” kusho uButt. "Ufuna ukuthi ilulame kancane, kodwa futhi iphefumule futhi ibe nekhono lokudonsa."
Ithimba labacwaningi lalungisa ama-nonwovens anogqinsi oluhlukahlukene futhi lahlanganiswa neshidi elilodwa noma amabili endwangu kakotini, okwaphumela ezinhlotsheni eziyi-13 zokuhlolwa.
Ukuhlola kubonise ukuthi into eyinhlanganisela ithuthukise ukumuncwa kwamanzi uma iqhathaniswa nempahla yasekuqaleni engalukiwe, kuyilapho igcina ukuphefumula okuhle. Izinto ezihlanganisiwe zimunca amanzi izikhathi ezi-3-10 kunezindwangu ezingezona zikakotini. Inhlanganisela futhi igcina ikhono lama-nonwovens ukuthi alulame ekweluleni, okuwavumela ukuthi amukele ukunyakaza okuzenzakalelayo ngaphandle kokuguqulwa.
Inqubo yokwenza ama-nonwovens ayinhlanganisela ingasebenzisa ukotini wekhwalithi ephansi futhi ngezinye izikhathi ize imoshe noma ikotini egaywe kabusha kusukela ekukhiqizeni imikhiqizo efana nezikibha namashidi ombhede, kusho uBarth, uprofesa wemicu nezindwangu e-Georgia Athletic Association. Ngakho-ke, umkhiqizo ovelayo unobungani bemvelo futhi ushibhile ukuwukhiqiza.
