Ma muli o ka emi ʻana o nā kumuwaiwai o ka honua, ka hōʻino ʻana o ke kinoea ʻōmaʻomaʻo i ke kaiapuni a me nā hopena ʻē aʻe i ke ola kanaka, ke piʻi nei ka ʻike o ka poʻe i ka nohona ʻōmaʻomaʻo. I nā makahiki i hala iho nei, ua kaulana ka huaʻōlelo o "nā mea maka i hana hou ʻia/hana hou ʻia" i nā lole a me ka ʻoihana lole home. ʻO kekahi mau lama kaulana o ka honua e like me Adidas, Nike, Uniqlo a me nā ʻoihana ʻē aʻe nā mea kākoʻo o kēia neʻe ʻana.
He aha ka fiber cellulose i hana hou ʻia a me ka fiber polyester i hana hou ʻia? Nui ka poʻe i huikau e pili ana i kēia.
1. He aha ka fiber cellulose i hana hou ʻia？
ʻO ka mea maka o ka fiber cellulose i hana hou ʻia he cellulose kūlohelohe (ʻo ia hoʻi ka pulupulu, ka hemp, ka ʻohe, nā lāʻau, nā lāʻau liʻiliʻi). No ka hana ʻana i kahi hana maikaʻi o ka fiber cellulose i hana hou ʻia, pono mākou e hoʻololi i ke ʻano kino o ka cellulose kūlohelohe. ʻAʻole i loli kona ʻano kemika. I ka ʻōlelo maʻalahi, ua unuhi ʻia ka fiber cellulose i hana hou ʻia a ua ʻoki ʻia mai ka mea kūlohelohe maoli ma o ka ʻenehana hana. No ka fiber hana ia, akā he kūlohelohe ia a ʻokoʻa mai ka fiber polyester. ʻAʻole ia no ka fiber kemika!
ʻO ke olonā Tencel, i ʻike ʻia hoʻi ʻo "Lyocell", he olonā cellulose i hana hou ʻia ma ka mākeke. E kāwili i ka pulp lāʻau o ka lāʻau coniferous, ka wai a me nā mea hoʻoheheʻe a hoʻomehana a hiki i ka hoʻoheheʻe piha ʻana. Ma hope o ka hoʻohemo ʻana i ka haumia a me ka milo ʻana, ua pau ke kaʻina hana o ka mea "Lyocell". Ua like ke kumumanaʻo ulana o Modal lāua ʻo Tencel. Loaʻa kāna mau mea maka mai nā lāʻau kumu. Ua māhele ʻia ke olonā ʻohe i loko o ke olonā pulp ʻohe a me ke olonā ʻohe kumu. Hana ʻia ke olonā pulp ʻohe ma o ka hoʻohui ʻana i nā mea hoʻohui hana i ka pulp o ka ʻohe Moso a hana ʻia e ka milo pulu. ʻOiai ua unuhi ʻia ke olonā ʻohe kumu mai ka ʻohe Moso ma hope o ka mālama ʻana i nā mea olaola kūlohelohe.
2, He aha ka fiber polyester i hana hou ʻia/hana hou ʻia?
Wahi a ke kumumanaʻo o ka hana hou ʻana, hiki ke hoʻokaʻawale ʻia nā ʻano hana o ka fiber polyester i hana hou ʻia i ʻelua mau ʻāpana: kino a me ke kemika. ʻO ke ʻano kino ke ʻano o ka hoʻokaʻawale ʻana, ka hoʻomaʻemaʻe ʻana a me ka hoʻomaloʻo ʻana i nā mea polyester ʻōpala a laila hoʻoheheʻe pololei i ka wili ʻana. ʻOiai ʻo ke ʻano kemika e pili ana i ka depolymerizing o nā mea polyester ʻōpala i ka polymerization monomer a i ʻole nā mea waena polymerization ma o nā hopena kemika; polymerization hana hou ma hope o ka hoʻomaʻemaʻe ʻana a me nā ʻanuʻu hoʻokaʻawale a laila hoʻoheheʻe i ka wili ʻana.
Ma muli o ka ʻenehana hana maʻalahi, ke kaʻina hana maʻalahi a me ke kumukūʻai hana haʻahaʻa o ke ʻano kino, ʻo ia ke ʻano nui e hana hou ai i ka polyester i nā makahiki i hala iho nei. ʻOi aku ma mua o 70% a 80% o ka hiki ke hana o ka polyester hana hou ʻia e hana hou ʻia e ke ʻano kino. Hana ʻia kāna olonā mai nā ʻōmole wai mineral ʻōpala a me nā ʻōmole Coke. He mea kaulana loa ia ma nā ʻāina i hoʻomohala ʻia e like me ʻEulopa a me ʻAmelika Hui Pū ʻIa no ka mea ua hoʻohana hou ʻia i nā ʻōpala. Hiki i ka polyester hana hou ke hōʻemi i ka hoʻohana ʻana i ka ʻaila, hiki i kēlā me kēia tona o ka olonā PET i hoʻopau ʻia ke mālama i 6 tona o ka ʻaila. Hiki iā ia ke hāʻawi i ka hōʻemi ʻana i ka haumia o ka ea a kaohi i ka hopena ʻōmaʻomaʻo. No ka laʻana: hana hou i kahi ʻōmole plastik me ka nui o 600cc = ka hoʻemi ʻana o ke kalapona o 25.2g = ka mālama ʻana i ka ʻaila o 0.52cc = ka mālama ʻana i ka wai o 88.6cc.
No laila, ʻo nā mea i hana hou ʻia/hana hou ʻia nā mea nui e ʻimi ʻia e ke kaiāulu i ka wā e hiki mai ana. He nui nā mea e pili pono ana i ko kākou ola e like me nā lole, nā kāmaʻa a me nā papa ʻaina i hana ʻia me nā mea hana hou e pili ana i ke kaiapuni. E ʻoi aku ka mahalo ʻia e ka lehulehu.
