I-polyester, ngokwesayensi eyaziwa ngokuthi i-polyethylene terephthalate (PET), ingenye yezintambo zokwenziwa ezisetshenziswa kakhulu emhlabeni jikelele. Ukusebenza kwayo okuhle kakhulu kanye nokusebenza kwezindleko{1}}kuyenze yaba isisekelo esibalulekile embonini yendwangu. Eminyakeni yamuva, ngokuthuthukiswa kwezobuchwepheshe kanye nokukhuthazwa kwezinqubo ezithinta imvelo, izindwangu ze-polyester ziye zaqhubeka zibonisa ukuncintisana okuqinile emakethe yamazwe ngamazwe.
Ngokombono wokusebenza, izinzuzo ezivelele zendwangu ye-polyester ilele emandleni azo aphezulu kanye nokuqina. Isakhiwo sayo se-fiber fibre ehlangene sinikeza amandla e-tensile ngo-30%-50% ngaphezu kukakotini, futhi sinikeza ukumelana okuhle kakhulu nokuhuzuka, okuyenza ifanele{5}}izingubo ezisetshenziswa kakhulu, imithwalo, nezindwangu zasembonini. Ngaphezu kwalokho, i-polyester ibonisa ukuzinza kwe-dimensional enhle kakhulu, enezinga{7}}lokuwasha lokuwasha elingaphansi kuka-1%, okuyenza ifaneleke kahle{9}}izingubo ezidinga ukulingana okunembile. Ngokusebenza, ngokuguqulwa, i-polyester ingenziwa i-UV{10}}imelane, amanzi{11}} kanye{12}}nebala, futhi isheshe{13}}yome, isuse umswakama, ikwenze isetshenziswe kabanzi ezimpahleni zemidlalo nangaphandle.
Enye inzuzo ebalulekile yokuncintisana ye-polyester izindleko zayo-ezisebenza kahle nezici ezihambisana nemvelo. Yenziwe nge-petrochemical byproduct, i-polyester inomthombo wezinto ezingavuthiwe ozinzile futhi isebenzisa amandla amancane ukukhiqiza kunemicu yemvelo. Eminyakeni yamuva nje, imboni inciphise kakhulu ukukhishwa kwekhabhoni ngokuguqula amabhodlela epulasitiki asetshenzisiwe abe imicu ngokusebenzisa ubuchwepheshe be- “polyester obugaywe kabusha”. Ngaphezu kwalokho, ukuthuthukiswa{4}kwe-polyester esekelwe ku-bio kuqhubekisela phambili imfashini esimeme. Lezi zindlela ezintsha zinikeze i-polyester isikhundla esibalulekile emakethe yomhlaba, lapho imfashini esheshayo nokuvikelwa kwemvelo kubaluleke ngokulinganayo.
Izindwangu ze-polyester zithola ukuthambekela kokuhlukahluka ekusetshenzisweni kwazo. Ezimpahleni, i-polyester-imixube kakotini (isb, 65% i-polyester/35% kakotini) inikezela ngokuqina nokunethezeka, okubusa imakethe yokugqokwa okusemthethweni, njengamahembe namasudi. I-polyester ehlanzekile isetshenziswa ngokuyinhloko engutsheni esebenzayo, njengezikibha zezemidlalo-nezingubo zokubhukuda. Ezindwangu zasendlini, i-polyester isetshenziswa kakhulu kumakhethini nasezindwangu zosofa, futhi izakhiwo zayo eziqinile-ezimelana nokushwabana{10}ezingenayo imibimbi zifunwa kakhulu yimboni yamahhotela. Emkhakheni wezimboni, intambo ye-polyester yezimboni isetshenziswa{12}ezintweni ezinamandla njengezintambo zamasondo namabhande ezihlalo, okubonisa ukwethembeka{13}kwebanga lobunjiniyela.
Njengamanje, iShayina, umkhiqizi omkhulu we-polyester emhlabeni, yenza ngaphezu kwama-70% wamandla okukhiqiza emhlabeni wonke futhi ngokuqhubekayo ithuthukisa inani elengeziwe lemikhiqizo yayo ngokusungula izinto ezintsha zobuchwepheshe. Njengoba isidingo sabathengi bomhlaba jikelele{2}}sokusebenza okuphezulu, izindwangu ezisimeme ziyakhula, izindwangu ze-polyester ziqinisa nakakhulu isikhundla sazo semakethe ngokuphindaphinda kwezobuchwepheshe. Kubasebenzi bezohwebo bakwamanye amazwe, ukuqonda okujulile kwezimpawu ze-polyester namathrendi embonini kuzobasiza ukuba babambe ngokunembile amathuba ebhizinisi ale nto ewumgogodla.
