Kiʻi poliester(polyethylene terephthalate) ua polymerized mai ka waikawa terephthalic i hoʻomaʻemaʻe ʻia (PTA) a me ka ethylene glycol.ʻO ka hiʻohiʻona he laiki granular, a he nui nā ʻano like (mālamalama āpau, hapalua kukui, kukui nui, cationic, kēia pau ʻana).
I loko o ka makeke quotation o polyester chips, 'ike pinepine oe i ka hua'ōlelo "malamalama nui", "semi-extinction" a me ka "kukui", i oleloia maanei no ka titanium dioxide (TiO2) maʻiʻo i ka polyester chips, hoʻohui i ka titanium dioxide (TiO2). i ka hehee ana e hoemi i ka luster o ka pulupulu."Malamalama nui" (ua kapa ʻia ʻo Yizheng chemical fiber "super light") ʻo ka ʻike o ka titanium dioxide i loko o nā ʻāpana polyester he zero;ʻO ka ʻike o ka titanium dioxide i loko o ka ʻāpana polyester "mālamalama" ma kahi o 0.1%;ʻO ka maʻiʻo o ka titanium dioxide i ka "semi-dull" polyester chip he (0.32±0.03) %;ʻO ka maʻiʻo titanium dioxide i loko o ka "full extinction" polyester chip he 2.4% a 2.5%.
Me ka hoʻonui nui ʻana o ka hoʻokele waiwai honua a me ka hoʻonui ʻana i ka nohona o nā kānaka, ua ulu wikiwiki ka ʻoihana lole a me nā lole.Ua hoʻohana nui ʻia ka puʻupuʻu polyester semi-dull no kona dyeability maikaʻi loa, ikaika kiʻekiʻe a me nā waiwai hoʻoponopono maikaʻi loa, a e hoʻonui ʻia ke kahua noi i kēlā me kēia lā, a lilo i kumu kumu no ka fiber textile, polyester industrial film, a me nā māla ʻē aʻe.
E like me ka hoʻohana ʻana i ka ʻāpana hiki ke hoʻokaʻawale ʻia i ka ʻāpana fiber grade polyester slice, ka ʻāpana polyester ʻāpana a me ka ʻāpana polyester kiʻiʻoniʻoni ʻekolu ʻāpana.
Hoʻohana ʻia nā ʻāpana fiber grade polyester e hana i ka polyester staple fiber a me ka filament polyester, ʻo ia nā mea maka no ka hoʻoponopono ʻana i nā fibers a me nā huahana pili o nā ʻoihana polyester fiber.Hoʻokaʻawale ʻia nā ʻāpana polyester pahu pahu i ʻelua mau ʻāpana o ka copolymerization a me ka homopolization, hiki ke hoʻokaʻawale ʻia i loko o nā hue wai mineral, nā hue inu carbonated, nā ipu meaʻai ʻē aʻe a me nā mea hoʻopihapiha e like me nā hoʻohana like ʻole.Mai ka hiki ʻana mai o ka kiʻiʻoniʻoni polyester i ka makahiki 1950, ma muli o kāna mau waiwai mechanical maikaʻi loa, ke kūpaʻa kemika a me ke kūpaʻa dimensional, ʻoiai ua hoʻomohala wikiwiki ʻia kahi kiʻi ʻoniʻoni uila a hoʻohana nui ʻia.Me ka hoʻomohala ʻana o ka ʻoihana mea hana home, ua piʻi wikiwiki ka hoʻohana ʻana i ke kiʻi polyester mānoanoa.I nā makahiki i hala iho nei, ua hoʻohana nui ʻia ka kiʻiʻoniʻoni polyester i nā mea hoʻopihapiha, nā mea paʻi, nā mea kūkulu hale, nā lako keʻena, nā mea magnetic a me nā mea kiʻi kiʻi a me nā ʻano kīwila ʻē aʻe e like me ka ʻokiʻoki a me nā ʻenehana kiʻekiʻe.
I kēia manawa, ʻo nā mea hana polyester nui he hana hoʻokahi, ʻaʻole hana hou ka PTA a me MEG polymerization i nā ʻāpana, akā e haʻalele i ka loulou waena e hana pololei i ka fiber a me ka filament.ʻO ka semi-extinction i loko o ka ʻāpana he 60%, akā ʻaʻohe mākeke, ʻaʻohe hoʻokūkū, a maopopo ka mākeke.ʻO ka hana ʻana o ka wai mineral a me nā ʻōmole inu ʻē aʻe me nā ʻāpana, ʻoi aku ka nui o ka hana o kēia manawa, ʻaʻole kūlike ka maikaʻi o nā mea hana.Hiki i hoʻokahi tona polyester ke hana ma mua o 33,000 mau hue.Eia kekahi, ʻo ka pepa i hana hou ʻia, ʻo ia hoʻi, ua hana hou ʻia nā ʻōmole ʻōpala i mea e hana ai i ka fiber staple, ke kumu kūʻai haʻahaʻa, ke kumu kūʻai haʻahaʻa, a me ka hoʻomaʻemaʻe ʻana i ke kaiapuni.Akā ʻoi aku ka koʻikoʻi o ka smuggling, hopohopo i ka wā e hoʻopaʻa ʻia ai ka wā e hiki mai ana e hoʻopau i ke kauoha mākeke.
