Ngenxa yokuncipha kwezinsiza emhlabeni wonke, ukulinyazwa kwesisi esibamba ukushisa endaweni ezungezile kanye neminye imithelela empilweni yomuntu, ukuqwashisa kwabantu ngokuphila ngokuluhlaza kuya ngokuba ngcono futhi kuba ngcono.Eminyakeni yamuva nje igama elithi "izinto zokusetshenziswa ezivuselelwe/ezigaywe kabusha" liya ngokuya liduma embonini yezingubo zokugqoka kanye nendwangu yasekhaya.Ezinye izinhlobo zokugqoka ezidumile zomhlaba wonke ezifana ne-Adidas, i-Nike, i-Uniqlo nezinye izinkampani zingabagqugquzeli balo mnyakazo.
Iyini i-cellulose fiber evuselelwe kabusha kanye ne-polyester fiber evuselelwe kabusha?Abantu abaningi badidekile ngalokhu.
1. Iyini i-cellulose fiber evuselelwe kabusha?
Izinto ezingavuthiwe zomucu we-cellulose ovuselelwe kabusha yi-cellulose yemvelo (okungukuthi ukotini, i-hemp, uqalo, izihlahla, izihlahla).Ukwakha ukusebenza okungcono kwefayibha ye-cellulose evuselelwe sidinga nje ukushintsha ukwakheka komzimba kwe-cellulose yemvelo.Ukwakheka kwayo kwamakhemikhali kuhlala kungashintshile.Ukuyibeka ngendlela elula, i-cellulose fiber evuselelwe kabusha ikhishwa futhi iphonswe kusuka ezintweni zangempela zemvelo ngobuchwepheshe bokwenziwa.Ingowe-fiber yokwenziwa, kodwa ingokwemvelo futhi ihlukile ku-polyester fiber.AKUYONA eye-chemical fiber!
I-Tencel fiber, eyaziwa nangokuthi "i-Lyocell", iyifayibha ye-cellulose evamile ekhiqizwa kabusha emakethe.Hlanganisa i-pulp yokhuni yesihlahla se-coniferous, amanzi nezincibilikisi bese ushisa kuze kuqedwe ngokuphelele.Ngemuva kokususwa kokungcola nokuphotha inqubo yokukhiqiza "Lyocell" impahla isiqediwe.Isimiso sokuluka se-Modal ne-Tencel siyefana.Izinto zayo zokusetshenziswa zitholakala emahlathini okuqala.I-bamboo fiber ihlukaniswe yaba yi-bamboo pulp fiber kanye ne-bamboo fiber yasekuqaleni.I-bamboo pulp fiber yenziwa ngokungeza izithasiselo ezisebenzayo ku-pulp ye-Moso bamboo futhi icutshungulwe ngokuphotha okumanzi.Ngenkathi i-bamboo fiber yasekuqaleni ikhishwa ku-Moso bamboo ngemva kokwelashwa kwe-agent yemvelo yemvelo.
2, Iyini i-polyester fiber evuselelwe kabusha / egaywe kabusha?
Ngokwesimiso sokuvuselela izindlela zokukhiqiza ze-polyester fiber evuselelwe zingahlukaniswa izigaba ezimbili: ngokomzimba namakhemikhali.Indlela ebonakalayo isho ukuhlunga, ukuhlanza nokomisa udoti we-polyester bese incibilika ukuphotha ngqo.Nakuba indlela yamakhemikhali ibhekisela ekususeni imfucumfucu ye-polyester izinto ku-polymerization monomer noma i-polymerization intermediates ngokusebenzisa ukusabela kwamakhemikhali;ukuvuselelwa kwe-polymerization ngemva kokuhlanzwa kanye nezinyathelo zokuhlukanisa bese kuncibilika ukuphotha.
Ngenxa yobuchwepheshe obulula bokukhiqiza, inqubo elula kanye nezindleko eziphansi zokukhiqiza zendlela engokwenyama, kuyindlela evelele yokuvuselela i-polyester eminyakeni yamuva.Ngaphezu kuka-70% kuya ku-80% wamandla okukhiqiza we-polyester egaywe kabusha avuselelwa ngendlela ebonakalayo.Intambo yayo yenziwe ngamabhodlela amanzi amaminerali angcolile namabhodlela e-Coke.Idume kakhulu emazweni athuthukile njengase-Europe nase-United States ngoba iphinde isetshenziswe emfucumfucwini.I-polyester egaywe kabusha inganciphisa ukusetshenziswa kwamafutha, ithani ngalinye lentambo ye-PET eqediwe ingasindisa amathani angu-6 kawoyela.Kungaba negalelo ekunciphiseni ukungcoliswa komoya kanye nokulawula umphumela we-greenhouse.Isibonelo: ukugaywa kabusha kwebhodlela lepulasitiki elinevolumu engu-600cc = ukuncishiswa kwekhabhoni ka-25.2g = ukonga uwoyela ka-0.52cc = ukonga amanzi ngo-88.6cc.
Ngakho-ke izinto ezikhiqizwe kabusha/ezigaywe kabusha kuzoba izinto ezisetshenziswa umphakathi ngokuzayo.Izinto eziningi ezisondelene kakhulu nempilo yethu njengezingubo, izicathulo namatafula zenziwe ngezinto ezigaywe kabusha ezinobungani nemvelo.Kuzokwamukelwa kakhulu umphakathi.
