Ipolyesterlilaphu elenziweyo elidla ngokuthathwa kwipetroleum.Eli laphu lelinye lawona malaphu athandwayo ehlabathini, kwaye lisetyenziswa kumawaka eemveliso ezahlukeneyo zabathengi nakwimizi-mveliso.
I-Chemical, i-polyester i-polymer ngokuyinhloko iqulunqwe ngamacandelo ngaphakathi kweqela elisebenzayo le-ester.Uninzi lwemicu yepolyester esekwe kwisityalo eninzi yenziwe nge-ethylene, eyinxalenye yepetroleum enokuthi ithathwe kweminye imithombo.Ngelixa ezinye iindlela zepolyester zibola, uninzi lwazo azinjalo, kwaye ukuveliswa kwepolyester kunye nokusetyenziswa kunegalelo kungcoliseko kwihlabathi liphela.
Kwezinye izicelo, i-polyester inokuba yiyo yodwa imveliso yempahla, kodwa ixhaphake kakhulu ukuba i-polyester idityaniswe nekotoni okanye enye i-fiber yendalo.Ukusetyenziswa kwepolyester kwisinxibo kunciphisa iindleko zemveliso, kodwa kwakhona kunciphisa ukukhululeka kwempahla.
Xa idityaniswe nomqhaphu, ipolyester iphucula ukushwabana, ukuqina, kunye nokushwabana kweprofayili yale fayibha yendalo iveliswa ngokubanzi.Ilaphu lePolyester lichasene kakhulu neemeko zokusingqongileyo, nto leyo eyenza ukuba ilungele ukusetyenziswa kwexesha elide kwizicelo zangaphandle.
Ilaphu esilaziyo ngoku njengepolyester laqala ukunyuka lisiya kwindima yalo ebalulekileyo kuqoqosho lwangoku ngo-1926 njengeTerylene, eyathi yadityaniswa okokuqala yi-WH Carothers e-UK.Kuyo yonke iminyaka yee-1930 kunye nee-1940, izazinzulu zaseBritane zaqhubeka nokuphuhlisa iindlela ezingcono zelaphu le-ethylene, kwaye le migudu ekugqibeleni yafumana umdla wabatyali-mali baseMelika kunye nabaqambi.
Ifiber yePolyester yaphuhliselwa ukusetyenziswa ngobuninzi yiDuPont Corporation, ekwaphuhlise nezinye iintsinga zokwenziwa ezidumileyo njengenayiloni.Ngexesha leMfazwe yeHlabathi yesiBini, ama-Allied powers azifumana ekwimfuno eyongeziweyo yeefiber zeparachute kunye nezinye izixhobo zemfazwe, kwaye emva kwemfazwe, iDuPont kunye namanye amaqumrhu aseMelika bafumana intengiso entsha yabathengi kwizinto zabo zokwenziwa kumxholo woqoqosho lwasemva kwemfazwe.
Ekuqaleni, abathengi babenehlombe malunga neprofayili ephuculweyo yokuqina kwepolyester xa kuthelekiswa nemicu yendalo, kwaye ezi zibonelelo zisasebenza nanamhlanje.Kumashumi eminyaka akutshanje, nangona kunjalo, impembelelo enobungozi yokusingqongileyo yolu cwecwe lwenziwe yacaca ngokweenkcukacha ezinkulu, kwaye isimo sabathengi kwi-polyester sitshintshe kakhulu.
Nangona kunjalo, i-polyester isala enye yezona mpahla ziveliswa kakhulu kwihlabathi, kwaye kunzima ukufumana iimpahla zabathengi ezingenayo ipesenti ye-polyester fiber.Impahla equlethe i-polyester, nangona kunjalo, iya kunyibilika kubushushu obugqithisileyo, ngelixa uninzi lweefiber zendalo zitsha.Imicu enyibilikisiweyo inokubangela umonakalo ongenakulungiseka emzimbeni.
Thenga umgangatho ophezulu, ngexabiso eliphantsiilaphu lomandlalo wepolyesterApha.
