Abaphandi kwiDyunivesithi yaseGeorgia baphuhlise imathiriyeli entsha enezakhiwo ezilungele izixhobo zonyango ezinjengeemaski kunye neebhanti. Ikwayinto ehambelana nendalo esingqongileyo kunezixhobo ezisetyenziswa ngoku.
Ukusebenzisa ii-nonwovens (amalaphu enziwe ngokudibanisa iifiber ngaphandle kokulukwa okanye ukunitha), iqela elikhokelwa nguGajanan Bhat likwazile ukwenza izinto eziguquguqukayo, eziphefumlayo kunye nezifunxayo ezilungele izixhobo zonyango. Ukubandakanywa komqhaphu kwenza ukuba izinto ezibangelwayo zikhululeke esikhumbeni (into ebalulekileyo kwiinjongo zonyango) kwaye kulula ukwenza umquba, okwenza kube lula ukusingqongileyo kuneemveliso ezifanayo ngoku kwimarike.

Ngenkxaso-mali evela kwi-USDA, abaphandi bavavanya imidibaniso eyahlukeneyo yomqhaphu kunye ne-nonwovens, kunye nee-nonwovens zangaphambili, kwiipropati ezifana nokuphefumla, ukufunxa amanzi kunye nokwelula. Amalaphu adityanisiweyo aqhube kakuhle kuvavanyo, abonelela ngokuphefumla kakuhle, ukufunxwa kwamanzi amaninzi kunye nokuchacha kakuhle, oku kuthetha ukuba banokumelana nokuphinda-phinda ukusetyenziswa.
Imfuno ye-nonwovens iye yanda kwiminyaka yamuva nje, kwaye ixabiso lemarike kulindeleke ukuba lifike kwi-US $ 77 yebhiliyoni ngo-2027, ngokwengxelo evela kwi-Acumen Research and Consulting. Ii-nonwovens zisetyenziswa kakhulu kwiimveliso zasekhaya ezifana ne-diapers, iimveliso zococeko lwabasetyhini, kunye nezihluzo zomoya kunye namanzi. Azinamanzi, zibhetyebhetye, ziyaphefumla, kwaye ukukwazi kwazo ukucoca umoya kuzenza zilungele ukusetyenziswa kwezonyango.
"Ezinye zezi mveliso ezisetyenziselwa iinjongo ze-biomedical, ezifana nama-patches kunye nama-bandages, zifuna ukunweba kunye nokubuyisela emva kokwelula. Kodwa ngenxa yokuba badibana nomzimba, ukusebenzisa ikotoni kunokuba luncedo ngokwenene, ithi iKholeji yeNtsapho kunye noMthengi. Iinkonzo zathi uBarth, usihlalo weSebe le-Textiles, Merchandising kunye ne-Interior Design, owabhalisa kunye nomfundi we-Partifir kunye nombhali we-D. Shafiqul Islam.
Nangona umqhaphu awunwebeki njengelaphu elingalukwanga, uyafunxa kakhulu kwaye uthambile, nto leyo eyenza kube lula ukuwunxiba. Umqhaphu sesona sityalo siphambili eGeorgia kwaye siyinxalenye ebalulekileyo yoqoqosho lwelizwe. I-USDA ihlala ijonge ukusetyenziswa okutsha komqhaphu, kwaye uBarth ucebise ukuba "badibanise ii-nonwovens ezinwebekayo kunye nomqhaphu ukwenza into ephezulu kumxholo womqhaphu kunye nowolukileyo."

U-Barth, osebenza ngokukhethekileyo kwii-nonwovens, ukholelwa ukuba izinto ezisisiphumo zinokugcina iimpawu ezinqwenelekayo ze-nonwovens ngelixa kulula ukuyiphatha kunye nokuvundisa.
Ukuvavanya iimpawu ze-composites, i-Bhat, i-Sikdar kunye ne-Islam zidibanisa ikotoni kunye neentlobo ezimbini ze-nonwovens: i-spunbond kunye ne-meltblown. I-Spunbond nonwovens iqulethe iifiber ezirhabaxa kwaye ziyakwazi ukuqina ngakumbi, ngelixa i-nonwovens enyibilikayo enyibilikayo iqulethe imicu ephucukileyo kwaye ineempawu ezingcono zokuhluza.
“Umbono wawusithi, ‘Yeyiphi indibaniselwano eya kusinika iziphumo ezilungileyo?’” utshilo uButt. "Ufuna ukuba ichache kancinci, kodwa uphinde uphefumle kwaye ube nobuchule bokwenza izinto."
Iqela lophando lilungiselele ii-nonwovens ezinobunzima obahlukeneyo kwaye zidityaniswe neshiti enye okanye ezimbini zelaphu lomqhaphu, okukhokelela kwiindidi ezili-13 zokuvavanya.
Uvavanyo lubonise ukuba izinto ezidibeneyo ziye zaphucula ukufunxa kwamanzi xa kuthelekiswa neyona nto yasekuqaleni engalukiweyo, ngelixa igcina ukuphefumla kakuhle. Izinto ezixubileyo zifunxa amaxesha angama-3-10 amanzi amaninzi kunamalaphu angewona umqhaphu. I-composite ikwagcina amandla e-nonwovens ukuba abuyele ekoluleni, ebavumela ukuba bavumelane neentshukumo ezizenzekelayo ngaphandle kokuguqulwa.
Inkqubo yokwenza i-nonwovens ehlanganisiweyo inokusebenzisa umqhaphu okumgangatho ophantsi kwaye ngamanye amaxesha ilahle okanye isetyenziselwe ikotoni esetyenzisiweyo ekuvelisweni kweemveliso ezinjengeeT-shirts kunye namashiti ebhedi, utshilo uBarth, unjingalwazi wemicu kunye nelaphu kwiGeorgia Athletic Association. Ngaloo ndlela, imveliso ephumayo ihambelana nokusingqongileyo kwaye ivelisa ixabiso eliphantsi.
Uphononongo lupapashwe kwijenali ye-Industrial Textiles. Ababhali-bambisene nabo nguDoug Hinchliffe kunye noBrian Condon we-USDA yeZiko loPhando loMmandla waseMzantsi.
