Me ka hoʻomau mau ʻana o ka ʻenehana hana textile, ʻoi aku ka nui o nā fibers hou i lilo i mea maka no ka textiles. I kēia lā, e hoʻolauna nui wau iā ʻoe i ka ʻenehana ʻike o ka fiber polyester recycled.
Ua hoʻomaopopo ʻia i ka wā ma mua, ma muli o ka nele o nā ʻano loiloi a me ka hiki ʻole o nā keʻena hoʻāʻo e hoʻopuka i nā hōʻike qualitative, ʻaʻole hiki i nā ʻoihana ke hauʻoli i nā kulekele pili aupuni, a i ka manawa like i hoʻohālikelike ai i ka hōʻailona ʻana i kekahi mau huahana polyester.
He aha ka fiber polyester recycled (PET)?
ʻO ia hoʻi, hoʻohana hou ʻia nā mea textile polyester (PET) a me nā mea textile ʻōpala (PET) a hana ʻia i ka fiber polyethylene terephthalate.
Ma ka ʻōlelo a ka poʻe kamaʻāina, ʻo ka fiber polyester recycled (i kapa ʻia ma hope nei he polyester recycled) e pili ana i ka polyester i hana hou ʻia (e like me ka ʻōmole flakes, foam, ʻōpala siliki, ʻōpala pulp, ʻōpala ʻōpala, etc.) i hana ʻia e nā kaʻina hana hou. ʻO ka fiber Ester.
Kumu o ka Identification
Ma muli o ka ʻokoʻa koʻikoʻi ma waena o ke kaʻina hana o ka polyester recycled a me ka polyester puʻupaʻa, e hopena i nā ʻano ʻano like ʻole, ua hana ʻia ka hāpana e like me nā kūlana i ʻōlelo ʻia a hoʻāʻo ʻia ma kahi chromatograph wai kiʻekiʻe. E like me ka ʻokoʻa i ka pili kiʻekiʻe o ka hāpana ma lalo o nā manawa paʻa like ʻole, E hoʻokō i ke kumu o ka ʻike qualitative.
Kaʻina ʻike
1. Methanolysis
2. Pehu-Hoʻokiʻoki
3. Kiʻekiʻe hana wai chromatography ike
ʻO nā wai lapaʻau i hana ʻia ma ka 1 a me 2 ma luna aʻe e kau ʻia i ka ʻike chromatography wai kiʻekiʻe.
4. Ka hana ʻikepili a me ka ʻike
Hoʻololi ka polyester i ka ʻike a me ka hāʻawi ʻana i nā loulou macromolecular heterogeneous chain a me nā oligomers i ka wā o ka hoʻomākaukau ʻana, hiki ke hoʻohana ʻia i kumu no ka ʻike ʻana i ka polyester recycled a me ka polyester puʻupaʻa.
Hōʻike ʻia ka ʻike kikoʻī kikoʻī a me ka ʻike piko ma ka papa ma lalo.

E nānā i ka wā e hiki mai ana
Me ka hoʻonui ʻana o ka hoʻohana ʻana i ka polyester a me ka ʻike o ka poʻe i ka mālama ʻana i ke kaiapuni, ʻoi aku ka nui o ka nānā ʻana i ka hana hou ʻana o ka ʻōpala polyester. ʻO ka hoʻohana ʻana i ka ʻōpala polyester no ka hana ʻana i ka fiber polyester recycled hiki ke hōʻemi i nā kumukūʻai, hoʻemi i ka hoʻohana ʻana i ka aila, a hoʻomaikaʻi i nā pono waiwai, he mea nui ia i ka hoʻomohala mau ʻana o ka ʻoihana fiber kemikal.
I ka manawa like, me ka hoʻonui ʻana i ka nui o ka polyester recycled, ʻo ka hoʻopuka ʻana o ka hoʻololi ʻana i ka polyester recycled a me ka polyester puʻupaʻa ua hoʻonui nui ʻia ka nānā ʻana mai ka ʻoihana. ʻO ke kumu kūʻai o nā mea ʻelua e hōʻike ana i kahi correlation maikaʻi, a ʻo ka ʻike ʻana i ka ʻokoʻa ma waena o nā ʻenehana ʻelua ke loaʻa nei ka nānā ʻana.
