Ungcoliseko kushishino lwamalaphu
● U-Sun Ruizhe, umongameli we-China National Textile and Apparel Council, ukhe wathi kwi-Climate Innovation kunye ne-Fashion Summit ngo-2019 ukuba i-textile kunye nempahla yempahla iye yaba lishishini lesibini elikhulu lokungcolisa ihlabathi, okwesibini kuphela kwishishini leoli;
● Ngokutsho kwedatha evela kwi-China Circular Economy Association, malunga ne-26 yezigidi zeetoni zeempahla ezindala ziphonswa kwiitoti zenkunkuma kwilizwe lam minyaka yonke, kwaye eli nani liya kunyuka ukuya kwiitoni zezigidi ezingama-50 emva kwe-2030;
● Ngokoqikelelo lweBhunga leSizwe leMilaphu neZinxibo laseTshayina, ilizwe lam lilahla inkunkuma yamalaphu minyaka le, okulingana neetoni ezizizigidi ezingama-24 zeoli ekrwada.Okwangoku, uninzi lweempahla ezindala zisalahlwa ngokulahla inkunkuma okanye ukutshiswa, zombini ezo ziya kubangela ungcoliseko olumandla lwendalo.
Izisombululo kwiingxaki zongcoliseko – iifibers ezisekelwe kwibhayoloji
Iintsinga ze-Synthetic kumalaphu ngokubanzi zenziwe ngezinto zepetrochemical ekrwada, ezinje nge-polyester fibers (i-polyester), iifiber ze-polyamide (inayiloni okanye inayiloni), iifiber ze-polyacrylonitrile (ii-acrylic fibers), njl.
● Ngokunyuka kokunqongophala kwemithombo ye-oyile kunye nokuvuswa kolwazi lwabantu ngokukhuselwa kwendalo.Oorhulumente nabo sele beqalisile ukuthatha amanyathelo ahlukeneyo okunciphisa ukusetyenziswa kobutyebi be-oyile kwaye bafumane imithombo enokuphinda ihlaziyeke ngakumbi endaweni.
● Bechatshazelwa kukunqongophala kwe-oyile kunye neengxaki zokusingqongileyo, amaziko okuvelisa imichiza emveli afana ne-United States, i-European Union, kunye ne-Japan ziye zarhoxa ngokuthe ngcembe kwimveliso ye-chemical fiber, zaza zaguqukela kwii-bio-based fibers ezinengeniso engakumbi nezingachaphazeleki kangako. ngoovimba okanye ngokusingqongileyo.
Izinto ze-Bio-based polyester (PET / PEF) zingasetyenziselwa ukwenziwa kweefiber ezisekelwe kwi-bio kunyengesikhumba biobased.
Kwingxelo yamva nje ye "Textile Herald" kwi "Review and Prospect of World Textile Technology", yachazwa:
● I-100% ye-bio-based PET iye yahamba phambili ekungeneni kwishishini lokutya, njengeziselo ze-Coca-Cola, ukutya kwe-Heinz, kunye nokupakishwa kweemveliso zokucoca, kwaye iphinde yangena kwiimveliso zefayibha zeempawu zezemidlalo ezaziwayo ezifana ne-Nike. ;
● I-100% yeemveliso ze-PET ezisekelwe kwibhayoloji okanye i-bio-based PEF T-shirt ibonwe kwimarike.
Njengoko ulwazi lwabantu ngokhuseleko lokusingqongileyo luqhubeka lusanda, iimveliso ezisekwe kwibhayoloji ziya kuba neenzuzo zendalo kwiinkalo zonyango, ukutya kunye neemveliso zokhathalelo lwempilo ezinxulumene ngokusondeleyo nobomi bomntu.
● Isicwangciso selizwe lam “iSicwangciso soPhuhliso loShishino lweTextile (2016-2020)” kunye “noShishino lweTextile “ISicwangciso seMinyaka eHlanu yeShumi elineSithathu” INkcazelo yeNkqubela kwiNzululwazi neTekhnoloji ibonise ngokucacileyo ukuba ulwalathiso lomsebenzi olandelayo lu: kukuphuhlisa imathiriyeli entsha yefiber esekwe kwibhayoloji ukuze ithathe indawo. izibonelelo zepetroleum, ukukhuthaza uShishino loShishino lwemicu yaselwandle esekwe kwibhayoloji.
Yintoni i-bio-based fiber?
● Iintsinga ezisekelwe kwibhayoloji zibhekiselele kwiintsinga ezenziwe ngezinto eziphilayo ngokwazo okanye kwincindi zazo.Ngokomzekelo, i-polylactic acid fiber (i-PLA fiber) yenziwe ngeemveliso zezolimo ezinesitatshi ezifana nombona, ingqolowa, kunye ne-beet yeswekile, kunye ne-alginate fiber yenziwe nge-algae emdaka.
● Olu hlobo lwefiber esekwe kwibhayoloji alukho nje eluhlaza kunye nokusingqongileyo kuphela, kodwa lusebenza kakuhle kakhulu kunye nexabiso elongeziweyo.Umzekelo, iipropathi zomatshini, ukubola kwezinto eziphilayo, ukunxiba, ukungatsha, ukucoceka kwesikhumba, i-antibacterial, kunye nepropathi yokususa umswakama we-PLA fibers azikho ngaphantsi kunezo zemveli.Ifayibha yeAlginate yimathiriyeli ekrwada ekumgangatho ophezulu wokuveliswa kweempahla zonyango ezine-hygroscopic, ngoko ke inexabiso elikhethekileyo lesicelo kwicandelo lezonyango nakwimpilo.njengokuba, sinobizo olutsha lwezinto eziphathekayongethwathwa biobased/vegan.
Kutheni uvavanya iimveliso zomxholo we-biobased?
Njengoko abathengi besiya bethanda indalo, ekhuselekileyo, iimveliso eziluhlaza ezifumaneka kwibhayoloji.Imfuno yeentsinga ezisekwe kwibhayoloji kwimakethi yamalaphu iyanda imihla ngemihla, kwaye kunyanzelekile ukuphuhlisa iimveliso ezisebenzisa ubungakanani obuphezulu bezinto ezisekwe kwibhayoloji ukuze kuhluthwe inzuzo yokuqala yokuhambisa kwimarike.Iimveliso ezisekelwe kwi-Bio zifuna umxholo we-bio-based wemveliso nokuba kuphando kunye nophuhliso, ulawulo lomgangatho okanye izigaba zokuthengisa.Uvavanyo lwe-Biobased lunokunceda abavelisi, abasasazi okanye abathengisi:
● I-R&D yeMveliso: Uvavanyo lwe-Bio-based lwenziwa kwinkqubo yophuhliso lwemveliso ye-bio-based, enokuthi icacise umxholo we-bio-based kwimveliso ukuququzelela ukuphuculwa;
● Ulawulo lomgangatho: Ngexesha lenkqubo yokuveliswa kweemveliso ezisekelwe kwibhayoloji, iimvavanyo ezisekwe kwibhayoloji zinokuqhutywa kwimathiriyeli ekrwada ebonelelweyo ukuze kulawulwe ngokungqongqo umgangatho wemveliso ekrwada;
● Ukukhuthazwa nokuthengisa: Umxholo osekelwe kwi-Bio uya kuba sisixhobo esihle kakhulu sokuthengisa, esinokunceda iimveliso zizuze ukuthenjwa ngabathengi kwaye zibambe amathuba emarike.
Ndingawubona njani umxholo webhayoloji kwimveliso?– Carbon 14 uvavanyo
Uvavanyo lweCarbon-14 lunokwahlula ngokufanelekileyo izinto ezisekwe kwi-bio kunye ne-petrochemical-derived kwimveliso.Ngenxa yokuba izinto eziphilayo zanamhlanje ziqulethe i-carbon 14 kwixabiso elifanayo nekhabhoni ye-14 emoyeni, ngelixa izinto zepetrochemical zingenayo nayiphi na i-carbon 14.
Ukuba iziphumo zovavanyo lwe-bio-based kwimveliso yi-100% ye-bio-based content carbon, kuthetha ukuba imveliso yi-100% ye-bio-sourced;ukuba isiphumo sovavanyo lwemveliso yi-0%, oko kuthetha ukuba yonke imveliso yepetrochemical;ukuba isiphumo sovavanyo yi-50%, Kuthetha ukuba i-50% yemveliso iyimvelaphi yezinto eziphilayo kunye ne-50% yekhabhoni yemvelaphi yepetrochemical.
Imigangatho yovavanyo lwamalaphu ibandakanya umgangatho waseMelika weASTM D6866, umgangatho waseYurophu EN 16640, njl.
