Ngenxa yokuncipha kobutyebi behlabathi, ukonakala kwerhasi yegreenhouse kwindalo esingqongileyo kunye nezinye iimpembelelo kubomi babantu, ulwazi lwabantu ngokuphila kohlaza luya luphucuka.Kwiminyaka yakutsha nje igama elithi “recycled/recycled raw materials” liya lithandwa kakhulu kwimpahla nakwimizi-mveliso yamalaphu yasekhaya.Ezinye iimpawu zokunxiba ezidumileyo zamazwe ngamazwe ezifana ne-Adidas, i-Nike, i-Uniqlo kunye nezinye iinkampani zingabameli bale ntshukumo.
Yintoni ifayibha eselulosi ehlaziyiweyo kunye nefiber yepolyester ehlaziyiweyo?Abantu abaninzi babhidekile yile nto.
1. Yintoni i-fiber cellulose ehlaziyiweyo?
Imathiriyeli ekrwada yefiber eselulosi ehlaziyiweyo yiselulosi yendalo (okt umqhaphu, ihempe, i-bamboo, imithi, amatyholo).Ukudala ukusebenza okungcono kwefayibha ye-cellulose ehlaziyiweyo sifuna nje utshintsho lwesakhiwo somzimba we-cellulose yendalo.Ubume bayo beekhemikhali buhlala bungatshintshi.Ukuyibeka ngendlela elula, i-fiber cellulose ehlaziywayo ikhutshwe kwaye ihlanjululwe kwizinto ezibonakalayo zendalo ngokusebenzisa iteknoloji yokwenziwa.Iyeye-fiber eyenziweyo, kodwa iyindalo kwaye yahlukile kwi-polyester fiber.AYIKHO kwifayibha yemichiza!
Ifayibha yeTencel, ekwabizwa ngokuba yi “Lyocell”, yifiber eqhelekileyo ehlaziyiweyo kwimarike.Xuba i-pulp yomthi womthi we-coniferous, amanzi kunye nezinyibilikisi kunye nobushushu kude kube nokuchithwa okupheleleyo.Emva kokungcola kunye nokujikeleza inkqubo yokuveliswa kwezinto "Lyocell" igqityiwe.Umgaqo wokuluka weModal kunye neTencel uyafana.Izinto zayo eziluhlaza zivela kwimithi yokuqala.I-bamboo fiber yohlulwe ibe yi-bamboo pulp fiber kunye ne-original bamboo fiber.I-bamboo pulp fiber yenziwa ngokongeza izongezo ezisebenzayo kwintlama ye-Moso bamboo kwaye ilungiswa ngokujikeleza okumanzi.Ngelixa i-bamboo fiber yoqobo itsalwa kwi-Moso bamboo emva konyango lwe-agent yendalo yebhayoloji.
2, Yintoni ifiber yepolyester eyenziwe ngokutsha/esetyenzisiweyo?
Ngokomgaqo wokuvuselela iindlela zokuvelisa i-fiber ye-polyester ehlaziyiweyo inokwahlulwa ibe ngamacandelo amabini: ngokomzimba kunye neekhemikhali.Indlela ebonakalayo ithetha ukuhlenga-hlengisa, ukucoca kunye nokomisa inkunkuma ye-polyester kwaye inyibilikise ukujikeleza ngokuthe ngqo.Ngelixa indlela yeekhemikhali ibhekisa kwi-depolymerizing inkunkuma ye-polyester imathiriyeli kwi-polymerization monomer okanye i-polymerization intermediates ngokusabela kweekhemikhali;ukuvuselelwa kwepolymerization emva kokucocwa kunye namanyathelo okwahlula kwaye emva koko kunyibilike ukujikeleza.
Ngenxa yetekhnoloji yemveliso elula, inkqubo elula kunye nexabiso eliphantsi lemveliso yendlela yomzimba, yeyona ndlela ibalaseleyo yokuhlaziya i-polyester kwiminyaka yakutshanje.Ngaphezulu kwe-70% ukuya kwi-80% yomthamo wemveliso ye-polyester ehlaziyiweyo iphinda ihlaziywe ngendlela yenyama.Umsonto wayo wenziwa ngeebhotile zamanzi eminerali kunye neebhotile zeCoke.Ithandwa kakhulu kumazwe ahambele phambili njengeYurophu neMelika kuba iphinda isetyenziswe kwinkunkuma.I-polyester ehlaziyiweyo inokunciphisa ukusetyenziswa kweoli, itoni nganye ye-PET egqityiweyo ingagcina iitoni ezi-6 zeoli.Ingenza igalelo ekunciphiseni ukungcoliseka komoya kunye nokulawula impembelelo ye-greenhouse.Umzekelo: ukuhlaziya ibhotile yeplastiki kunye nomthamo we-600cc = ukunciphisa i-carbon ye-25.2g = ukonga kwe-oyile ye-0.52cc = ukonga amanzi kwe-88.6cc.
Ke ngoko imathiriyeli ehlaziyiweyo/esetyenzisiweyo iya kuba zezona zinto ziphambili ezilandelwa luluntu kwixesha elizayo.Izinto ezininzi eziyelelene ngokusondeleyo kubomi bethu njengempahla, izihlangu kunye neetafile zenziwe ngezinto ezilungele ukusetyenzwa kwakhona.Iya kwamkelwa ngakumbi nangakumbi luluntu.
