Iitshiphusi zepolyester(i-polyethylene terephthalate) i-polymerized ukusuka kwi-terephthalic acid ecocekileyo (PTA) kunye ne-ethylene glycol.Ukubonakala kwerayisi granular, kwaye kukho iintlobo ezininzi (konke ukukhanya, ukukhanya kwesiqingatha, ukukhanya okukhulu, i-cationic, oku kuphelelwa).
Kwikowuteshini yemarike yeetshiphusi zepolyester, udla ngokubona amagama athi "ukukhanya okukhulu", "ukutshabalala kwesiqingatha" kunye "nokukhanya", ezithethwa apha kumxholo wetitanium dioxide (TiO2) kwiitshiphusi zepolyester, ukongeza i-titanium dioxide (TiO2) kwinyibilika kukunciphisa ukukhazimla kwefiber."Ukukhanya okukhulu" (Yizheng ifayibha yemichiza ikwabizwa ngokuba "ukukhanya okuphezulu") umxholo we-titanium dioxide kwiitshiphu zepolyester ngu-zero;Umxholo we-titanium dioxide kwisilayi se-polyester "eqaqambileyo" malunga ne-0.1%;Umxholo we-titanium dioxide kwi-chip "semi-dull" ye-polyester yi-(0.32±0.03)%;Umxholo we-titanium dioxide kwi-chip ye-polyester "yokuphela ngokupheleleyo" yi-2.4% ukuya kwi-2.5%.
Ngokunyuka kophuhliso loqoqosho lwehlabathi kunye nokuphuculwa okunyukayo kwemigangatho yokuphila kwabantu, ishishini lempahla yengubo kunye nempahla liphuhliswe ngokukhawuleza.I-semi-buthe ye-polyester chip isetyenziselwe ngokubanzi ukudaya kwayo okugqwesileyo, ukomelela okuphezulu kunye neempawu ezibalaseleyo zokusetyenzwa, kwaye indawo yesicelo iya kwandiswa imihla ngemihla, kwaye ibe yeyona nto iphambili yezixhobo zefiber yelaphu, ifilimu yepolyester yoshishino, kunye nezinye iindawo.
Ngokutsho ukusetyenziswa isilayi inokohlulwa ibe ifayibha grade polyester isilayi, ibhotile grade polyester isilayi kunye film grade polyester isilayi iindidi ezintathu.
Iitshiphusi ze-Fiber grade polyester zisetyenziselwa ukwenza i-polyester staple filament kunye ne-polyester filament, eziyimathiriyeli ekrwada yokusetyenzwa kweentsinga kunye neemveliso ezinxulumene namashishini e-polyester fiber.Iitshiphusi ze-Bottle grade polyester zahlulwe zibe ziindidi ezimbini ze-copolymerization kunye ne-homopolization, ezinokuthi zohlulwe kwiibhotile zamanzi ezimbiwa, iibhotile zesiselo se-carbonated, ezinye izitya zokutya kunye nezinto zokupakisha ngokweendlela ezahlukeneyo zokusetyenziswa.Ukususela ekufikeni kwefilimu ye-polyester kwi-1950s, ngenxa yeempawu zayo ezintle kakhulu, ukuchasana kweekhemikhali kunye nokuzinza kwe-dimensional, njengoko ifilimu yokufakelwa kombane iphuhliswe ngokukhawuleza kwaye isetyenziswe ngokubanzi.Ngophuhliso loshishino lwezixhobo zasekhaya, ukusetyenziswa kwefilimu eshinyeneyo yepolyester kuye kwanda ngokukhawuleza.Kwiminyaka yakutshanje, ifilimu ye-polyester isetyenziswe ngokubanzi kwizinto zokupakisha, izinto zokuprinta, izixhobo zokwakha, izixhobo zeofisi, izixhobo zemagneti kunye nemathiriyeli yokufota kunye neminye imiba yoluntu kunye nokusika-umphetho kunye nobuchwepheshe obuphezulu.
Okwangoku, abavelisi abakhulu be-polyester yimveliso enenyathelo elinye, i-PTA kunye ne-MEG polymerization azisavelisi izilayi, kodwa zishiya ikhonkco eliphakathi ngqo zivelisa i-fiber esisiseko kunye ne-filament.I-semi-extinction kwi-akhawunti yesilayi i-60%, kodwa i-slicing spinning ayinayo imarike, akukho khuphiswano, kwaye imarike ibonakala.Ukuveliswa kwamanzi amaminerali kunye nezinye iibhotile zesiselo kunye namacwecwe, imveliso yangoku iye yagqithisa, umgangatho wabavelisi awufani.Itoni enye yepolyester inokwenza ngaphezulu kweebhotile ezingama-33,000.Ukongeza, iphepha elisetyenzisiweyo, oko kukuthi, iibhotile zeplastiki ezilahlwayo ziphinda zisetyenziswe ukuvelisa i-fiber esisiseko, ixabiso eliphantsi, ixabiso eliphantsi, kunye nokucoca okusingqongileyo.Kodwa ukurhweba ngokungekho mthethweni kubi kakhulu, unexhala lokuba xa ikamva elidwelisiweyo liya kuphazamisa ulungelelwaniso lwemarike.
