Xa uthengaizilayidi kunye nezinye iintlobo zezihlangu,njengembadada okanye iibhlokhi, omnye wemibuzo eqhelekileyoukubaabantu UCanzibe buza malungaimpahla-ngokukodwa, yintoni i-EVA? I-sole ye-EVA sisihlangu esineenzuzo ezininzi ezenza isiseko esifanelekileyo se-sumlomors.Ukubeka nje, i-EVA sole yi-plastic shoe shoe enokuthi ibe lula kwaye iguquguquke ngaphezu kwerabha.Lo ngumphezulu nje wokuba ezi soli ziyintoni kwaye yintoni inzuzo yazo ye-EVA sumlomoezi zi.
I-EVA, xa sithetha ngemichiza, yi-Ethylene-Vinyl Acetate, i-elastic co-polymer efana kakhulu nerabha kwaye isetyenziswa kwizicelo zasekhaya nakwimizi-mveliso.I-EVA ithathwa njengobuhlobo bokusingqongileyo kuba ayifuni't isebenzise iklorini kwimveliso yayo, kwaye inokuphinda isetyenziswe kwimveliso efana nebala lokudlala okanye iimethi zemizi-mveliso.Ngenxa yokuba yenziwe ngumntu kwaye inobuhlobo nezilwanyana, isetyenziswa ngokuqhelekileyo kwizihlangu ze-vegan.I-EVA ibonelela nge-cushion, intwasahlobo (i-rebound), kwaye iyamelana nokuqina kunye nokuqhekeka.Ikwamelana nemitha ye-UV, ayifuni't ukufunxa amanzi, kwaye uhlala bhetyebhetye kwingqele, yonke loo nto iyenza ibe luncedo kakhulu kwizihlangu zangaphandle.Ithambile kwaye ibhetyebhetye, i-EVA ngokobuchwephesha igwebu endaweni yerabha, njengoko yenziwa ngokwandisa iplastiki kunye nokubambisa iipokotho zerhasi (umoya) kwiindawo ezixineneyo ezahlukeneyo.Uninzi olubalekayo kunye nesihlangu esingaqhelekangangaphandleii soles zenziwe kwi-Eva.Kwiminyaka yakutshanje, iibrendi ezimbalwa ziguqukele kwi-PU (i-polyurethane) ukwakha ixesha elidengaphandleitekhnoloji yodwa, ngakumbi kwiibhutsi zokupakisha.Kodwa i-EVA isafunyenwe ine-rebound engaphezulu, ngelixa ifikelela kubomi bayo bokugqibela (uxinzelelo) ngokukhawuleza kune-PU.Wena'Ndiza kubona iimveliso ezininzi ezisebenzayo zisebenzisa indibaniselwano yobunini yeekhompawundi zerabha ezidityaniswe ne-EVA.Kwaye ngelixa i-market shoe market ngokwenene yavelisa i-EVA midsole, ngoku isetyenziswa ngokubanzi phantse kulo lonke uhlobo lwesihlangu, kubandakanywa, ukuba akunjalo, iimbadada.I-EVA sole ayinikezeli kuphela i-rebound kunye ne-cushion ekhankanywe ngasentla, kodwa ikhusela iinyawo kwimpembelelo njengoko unyawo ngalunye lubetha emhlabeni.I-rebound kwi-Eva ikunceda ukuba uphume kumkhondo ngamnye.Kodwa njengazo zonke izinto ezilungileyo, i-EVA iyaphela.Ngokuhamba kwexesha, i-EVA iya kucinezela kwaye ikhulule i-rebound yayo, ngelo xesha kufuneka itshintshwe.Kwisihlangu sokubaleka, kuthatha malunga neekhilomitha ezingama-300 ukufikelela kweli nqanaba.Kwezinye izihlangu, Oku kudla ngokwenzeka kuyo xa icinezela, iphulukane ne-rebound yayo, kwaye ekugqibeleni ifikelele kwinqanaba apho kufanele ukuba itshintshwe, rhoqo emva kweekhilomitha ezingama-300 kwisihlangu esibalekayo.Oku kuyahluka ngokuqinisekileyo ngokuba nzima kangakanani umsebenzisi, ukuhamba kwabo kunye noluphi uhlobo lweemayile abazibeka kwisihlangu.I-EVA midsoles iqhele ukubunjwa inaliti.Ukufezekisa ukuqina ngakumbi, abaninzi abathungi bezihlangu basebenzisa i-EVA midsoles eyenziwe ngoxinzelelo.Kule nkqubo, i-EVA ixinzelelwe kwi-mold ukwenzela ukuba i-midsole-to-be yenza ulusu lwangaphandle olunzima.Oku kongeza ubomi kwi-midsole, isakhiwo se-torsional, kwaye sivumela ukuhonjiswa okunje ngemibala, uyilo kunye neelogo.Ukusebenzisa i-EVA, abavelisi banokuphinda benze ubukhulu obuhlukeneyo kunye noxinaniso, bongeza i-cushion engaphezulu phantsi kwesithende, umaleko othambileyo phezu komgangatho onzima, kunye nento ebizwa ngokuba“ukuthumela”ukuthintela ukubizwa konyawo ngexesha lokuhamba kunye nokubaleka.Ekupheleni kosuku, yazi nje ukuba i-EVA yile nto ithambileyo, i-squishy layer phakathi kwendawo ephezulu kunye ne-outsole yesihlangu sakho esikhoyo sikukhusela kwaye songeze intwasahlobo encinci kwisinyathelo sakho.
