Iti efakwe kwingxowa ikhule ngokukhawuleza ngenxa yeenzuzo zayo "zobuninzi, ucoceko, lula, kunye nesantya", kwaye imakethi yeti ebhegi yehlabathi ibonisa ukukhula okukhawulezayo.
Njengempahla yokupakisha yeebhegi zeti,iphepha lokucoca itiakufanele kuqinisekiswe kuphela ukuba izithako ezisebenzayo zeti ziyakwazi ukusabalalisa ngokukhawuleza kwisobho setiyi ngexesha lenkqubo yokusela, kodwa kwakhona ukuthintela i-tea powder kwisikhwama ekungeneni kwisobho yetiyi. Emva kweminyaka yophuhliso, izinto zephepha lokucoca iti ziye zaguquka ngokuthe ngcembe ukusuka kwi-gauze, iphepha lokucoca, inayiloni, i-PET, i-PVC, i-PP kunye nezinye izixhobo ukuya kwifiber yombona.
Ifiber yombona, ekwaziwa ngokuba yipolylactic acid (PLA) fiber, iphuma kwimithombo yezityalo ehlaziyekayo efana nombona, iitapile, kunye neendiza zezityalo. Ine-biocompatibility elungileyo kunye ne-biodegradability, iipropathi ze-antibacterial, kunye nokuphefumla. Ayinakusetyenziswa kuphela ukwenza iibhegi zeti ezingalukwanga, kodwa zikwasetyenziswa kwindawo yokwenza iphepha elimanzi ukuvelisa iphepha lokupakisha ukutya elinje ngeebhegi zeti, iibhegi zekofu, kunyeiphepha lokucoca.
Ngoko, kugxininise kwiimpawu zokusebenza kwezinto ngokwazo, ziziphi iingenelo eziphambili zokusebenzisa i-PLA fiber ekwenzeni iphepha elimanzi?
1. Izinto eziphathekayo ziyindalo kwaye zinokudibana nokutya
Izinto eziluhlaza zefiber ye-polylactic acid zivela kwimithombo yezityalo ezivuselelekayo. Njengemathiriyeli eqinisekisiweyo yokhuseleko lokutya, ifayibha ye-polylactic acid ingasetyenziswa ngokubanzi kwiintlobo ezahlukeneyo zokutya, amayeza, kunye nezinye izicelo eziphezulu zephepha lasekhaya. Ukuthatha ukusetyenziswa kweebhegi zeti kunye nephepha lokucoca ikofu njengomzekelo, ukuzibeka ngokuthe ngqo emanzini ashushu ngaphandle kwemvula yeplastiki okanye ezinye izinto ezinobungozi zinobuhlobo ngakumbi kumzimba womntu.
2. I-Biodegradability
Ukuthatha ukusetyenziswa kweebhegi zeti njengomzekelo, inani elikhulu leebhegi zeti ezilahlwayo zityiwa kwihlabathi jikelele yonke imihla. Iibhegi zeti ezenziwe ngezinto zemveli zinomjikelo omde kakhulu wokuthotywa, oya kuzisa uxinzelelo olubalulekileyo kwindalo yendalo. Nangona kunjalo, iibhegi zeti okanye ezinye iimveliso ezenziwe ngezinto ze-polylactic acid zine-biodegradability egqwesileyo.
Iimveliso zelaphu ezilukiweyo zePolylactic acid zinokuthi ziboliswe ngokupheleleyo zibe yikharbon diokside kunye namanzi ziintsholongwane ezikwiindawo zendalo ezinobushushu obuthile kunye nokufuma, okufana nesanti, intlenga, kunye namanzi olwandle. Inkunkuma yemveliso ye-Polylactic acid inokubola ngokupheleleyo kwi-carbon dioxide kunye namanzi phantsi kweemeko zomgquba woshishino (ubushushu obungama-58 ℃, ukufuma 98%, kunye neemeko ze-microbial) kwiinyanga ezi-3-6; Ukuzaliswa komhlaba kwiindawo eziqhelekileyo nako kunokuzuza ukuthotywa phakathi kweminyaka emi-3-5.
3. Inokuxutywa kunye ne-pulp yokhuni okanye ezinye iintambo zendalo zokusetyenziswa
Iifiber ze-Polylactic acid zidla ngokuxutywa kumlinganiselo othile kunye nemicu yomthi, i-nanofibers, njl njl ukwenza i-pulp kunye nephepha. I-Polylactic acid idlala indima enkulu ekudibaniseni nasekuqiniseni, ngokudibanisa ezinye iifayili ngokushisa kunye nokushisa ukufezekisa injongo yokuqulunqa kunye nokomeleza. Ukongezelela, ngokulungelelanisa umlinganiselo we-slurry kunye nendlela yokucubungula, inokuhlangabezana neemfuno ezihlukeneyo zeemeko ezahlukeneyo.
4. I-Ultrasonic thermal bonding inokufezekiswa
Ngokusebenzisa i-polylactic acid fibers ukwenza i-pulp kunye nephepha, i-ultrasonic thermal bonding inokufezekiswa kwimveliso elandelayo, engagcini nje kuphela umsebenzi kunye nokunciphisa iindleko, kodwa iphucula ukusebenza kakuhle kwemveliso.
5. Ukucoca ukusebenza
Iphepha lokucoca iti elenziwe ngefiber ye-polylactic acid inokusebenza kakuhle kokucoca kunye namandla aphezulu amanzi, anokugcina ngokufanelekileyo amagqabi eti kunye namanye amasuntswana aqinileyo, ngelixa ivumela incasa kunye nevumba leti ukuba lingene ngokupheleleyo.
Ukongeza kwiphepha lokucoca iti, ifayibha ye-polylactic acid ingasetyenziswa kwiphepha lokucoca amayeza esintu, iphepha lokucoca ikofu, kunye nelinye iphepha lokupakisha ukutya.
