Polyesterke lesela la maiketsetso leo hangata le tsoang ho petroleum.Lesela lena ke le leng la masela a ratoang ka ho fetisisa lefatšeng, 'me le sebelisoa mekhoeng e likete e fapaneng ea bareki le ea indasteri.
Ka lik'hemik'hale, polyester ke polymer haholo-holo e entsoeng ka metsoako ka har'a sehlopha se sebetsang sa ester.Boholo ba likhoele tsa maiketsetso le tse ling tsa polyester tse thehiloeng limela li entsoe ka ethylene, e leng karolo ea petroleum eo le eona e ka nkiloeng mehloling e meng.Le hoja mefuta e meng ea polyester e ka senyeha, boholo ba eona ha e joalo, 'me tlhahiso le tšebeliso ea polyester li kenya letsoho tšilafalo lefatšeng ka bophara.
Lisebelisoa tse ling, polyester e ka 'na ea e-ba eona feela karolo ea lihlahisoa tsa liaparo, empa ho tloaelehile hore polyester e kopanngoe le k'hothone kapa fiber e' ngoe ea tlhaho.Tšebeliso ea polyester liaparong e fokotsa litšenyehelo tsa tlhahiso, empa hape e fokotsa boiketlo ba liaparo.
Ha e kopantsoe le k'hothone, polyester e ntlafatsa ho honyela, ho tšoarella, le boemo bo sosobaneng ba fiber ena ea tlhaho e hlahisoang haholo.Lesela la polyester le hanyetsana haholo le maemo a tikoloho, e leng se etsang hore e be se loketseng bakeng sa tšebeliso ea nako e telele lits'ebetsong tsa ka ntle.
