Nā te mimiti haere o ngā rauemi o te ao, te kino o te hau kati kōtuhi ki te taiao, me ētahi atu pānga ki te oranga o te tangata, kei te pai haere te mōhiotanga o te tangata ki te oranga matomato. I ngā tau tata nei, kei te rongonui haere te kupu "ngā rauemi mata kua whakahoutia/kua hangarua" i roto i te umanga kakahu me te kakahu kāinga. Ko ētahi o ngā waitohu kakahu rongonui o te ao pērā i a Adidas, Nike, Uniqlo me ētahi atu kamupene ko rātou ngā kaitautoko o tēnei kaupapa.
He aha te muka cellulose kua whakahoutia me te muka polyester kua whakahoutia? He maha ngā tāngata e pōhēhē ana mō tēnei.
1. He aha te muka cellulose kua whakahoutia?
Ko te rauemi mata o te muka cellulose kua whakahoutia ko te cellulose tūturu (arā, te miro, te hāmi, te pāpaka, ngā rākau, ngā rakau iti). Hei whakapai ake i te mahi a te muka cellulose kua whakahoutia, me whakarerekē noa te hanganga ā-tinana o te cellulose tūturu. Kāore anō kia rerekē tōna hanganga matū. Ki te kī ngāwari, ka tangohia te muka cellulose kua whakahoutia, ka whakatōkia mai i te rauemi tūturu taketake mā te hangarau horihori. Nō te muka horihori, engari he tūturu, he rerekē i te muka polyester. EHARA i te muka matū!
Ko te muka Tencel, e mōhiotia ana ko "Lyocell", he muka cellulose kua whakahoutia noa i te mākete. Whakaranua te penupenu rakau o te rākau coniferous, te wai me ngā whakarewa ka whakamahana kia memeha rawa. I muri i te tango i te poke me te miro, kua oti te tukanga whakaputa rauemi "Lyocell". He rite tonu te kaupapa raranga o Modal me Tencel. Ko ōna rauemi mata i ahu mai i ngā rakau taketake. Ka wehea te muka bamboo ki te muka penupenu bamboo me te muka bamboo taketake. Ka hangaia te muka penupenu bamboo mā te tāpiri i ngā tāpiringa mahi ki te penupenu o te bamboo Moso ka tukatukahia mā te miro mākū. Ko te muka bamboo taketake ka tangohia mai i te bamboo Moso i muri i te maimoatanga matū koiora taiao.
2, He aha te muka polyester kua whakahoutia/kua hangarua?
E ai ki te mātāpono o te whakahoutanga, ka taea te wehewehe i ngā tikanga whakaputa o te muka polyester kua whakahoutia kia rua ngā wāhanga: te ā-tinana me te matū. Ko te tikanga ā-tinana ko te wehewehe, te horoi me te whakamaroke i ngā rauemi polyester para, kātahi ka huri tika i te whakarewa. Ko te tikanga matū ia e pā ana ki te tango i te polymerization o ngā rauemi polyester para ki te monomer polymerization, ki ngā takawaenga polymerization rānei mā roto i ngā tauhohenga matū; ko te whakahoutanga polymerization i muri i te horoinga me te wehenga, kātahi ka huri rewa.
Nā te ngāwari o te hangarau whakaputa, te tukanga māmā me te iti o te utu whakaputa o te tikanga ā-tinana, koinei te tikanga matua mō te hangarua i te polyester i ngā tau tata nei. Neke atu i te 70% ki te 80% o te kaha whakaputa o te polyester hangarua ka whakahoutia mā te tikanga ā-tinana. Ko tōna miro he mea hanga mai i ngā pounamu wai kohuke para me ngā pounamu Coke. He tino rongonui i ngā whenua whakawhanake pērā i a Ūropi me te Hononga o Amerika nā te mea ka whakamahia anōtia mai i ngā para. Ka taea e te polyester hangarua te whakaiti i te whakamahinga o te hinu, ka taea e ia tana o te miro PET kua oti te penapena i te 6 tana o te hinu. Ka taea e ia te whai wāhi ki te whakaiti i te parahanga o te hau me te whakahaere i te pānga kati kōtuhi. Hei tauira: te hangarua i te pounamu kirihou he 600cc te rahinga = te whakaiti waro o te 25.2g = te penapena hinu o te 0.52cc = te penapena wai o te 88.6cc.
Nō reira, ko ngā rauemi kua whakahoutia/kua hangaruatia ka noho hei rauemi matua e rapuhia ana e te hapori ā muri ake nei. He maha ngā taonga e pā tata ana ki ō tātou oranga pērā i ngā kākahu, ngā hu me ngā tēpu he mea hanga ki ngā rauemi hangarua e pai ana ki te taiao. Ka nui haere te maioha o te marea ki tēnei rauemi.
