Kwiminyaka yakutshanje, ukuqonda kwehlabathi ngokubaluleka kokukhuselwa kwendalo kuye kwanda.Njengoko ubutyebi bendalo buphela kwaye namazinga ongcoliseko enyuka, ukufumana izisombululo ezizinzileyo kubalulekile.Esinye sezisombululo esifumene ingqwalasela enkulu kukusetyenziswa kwe-PLA (i-polylactic acid) izixhobo ze-spunbond kumashishini ahlukeneyo.Ukongeza kwiinzuzo zayo ezininzi, izixhobo ze-PLA ze-spunbond nazo zidlala indima ebalulekileyo ekukhuselweni kwendalo.
I-PLA spunbondlilaphu elingaphothiweyo elivela kwimithombo ehlaziyekayo efana nombona kunye nommoba.Ngokungafaniyo nezixhobo zokwenziwa zemveli, imathiriyeli ye-PLA spunbond iyabola kwaye ayinagalelo ekuqokeleleni inkunkuma yeplastiki kwiindawo zokulahla inkunkuma okanye elwandle.Ngokusebenzisa i-PLA spunbond endaweni yezixhobo zemveli, sinokunciphisa kakhulu impembelelo yokusingqongileyo ehambelana nokuveliswa kunye nokulahlwa kweemveliso ezingenayo i-biodegradable.
Inkqubo yokwenziwa kwePLA spunbond imathiriyelikananjalo ineengenelo zokusingqongileyo.Ifuna amandla amancinci kwaye ivelise ukukhutshwa kwegesi ye-greenhouse encinci kunemveliso ye-petroleum-based synthetic materials.Oku kunceda ukunciphisa utshintsho lwemozulu kunye nokunciphisa indawo yethu yekhabhoni.Ukongezelela, ukuveliswa kwe-PLA spunbond akubandakanyi ukusetyenziswa kweekhemikhali ezinobungozi okanye i-solvents, okwenza kube yinto ekhuselekileyo kunye neyokugcina ukhetho lwendalo kunye nempilo yabantu.
Ukongeza kwinkqubo yokuvelisa, imathiriyeli ye-PLA ye-spunbond yamkelwa ngenxa yokuguquguquka kwayo kunye nokuqina.Ingasetyenziswa kuluhlu olubanzi lwezicelo ezibandakanya ukupakishwa, ezolimo, iimoto, iimveliso zonyango kunye nococeko.Amandla ayo kunye nokumelana nokukrazula kuyenza ilungele ukusetyenziswa kwezinto ezahlukeneyo ngaphandle kokubeka esichengeni izibonelelo zayo zendalo.Ngokubandakanya imathiriyeli ye-PLA spunbond kubomi bethu bemihla ngemihla, sinokubheka kwikamva elizinzileyo nelinobuhlobo nokusingqongileyo.
Omnye umba obalulekileyo we-PLA spunbond ngamandla ayo njengenye indlela yokusetyenziswa kweplastiki enye.Ngokukhula kwenkxalabo malunga nongcoliseko lweplastiki, ukufumana ezinye iindlela kuye kwabaluleka.I-PLA spunbond inikezela ngesisombululo esisebenzayo njengoko sinokuvundiswa ngokulula phantsi kweemeko ezilawulwayo, ukunciphisa kakhulu impembelelo yokusingqongileyo.Ngokusebenzisa izixhobo ze-PLA ze-spunbond ekupakishweni kunye neemveliso ezisetyenziselwa enye, sinokuphelisa imfuno yezinto ezingenakuphinda zisetyenziswe ezinegalelo ekukhuleni kwenkunkuma yeplastiki.
Ukuqukumbela, ukhuseleko lokusingqongileyo ngumba ongxamisekileyo wehlabathi, kwaye ukufumana izisombululo ezizinzileyo kubalulekile.Izixhobo ze-PLA ze-spunbond ziyindlela ethembisayo kwizinto zokwenziwa zemveli kwaye zinceda ukukhusela okusingqongileyo.I-biodegradability yayo, ukusetyenziswa kwamandla aphantsi kunye nokunciphisa i-carbon footprint kuyenza ibe sisixhobo esixabisekileyo ekusukeleni kwethu ukukhuselwa kwendalo.Ngokwamkela i-PLA spunbond kuwo wonke amashishini kunye nokutshintsha iiplastiki ezisetyenziselwa enye, sinokuthatha inyathelo elibalulekileyo elibhekiselele kwikamva eliluhlaza, elizinzileyo.
