Polyester fiber, feem ntau hu ua" polyester" ;. Nws yog cov hluavtaws ua hluavtaws tau los ntawm kev txau polyester tau txais los ntawm polycondensation ntawm cov organic dibasic acid thiab diol, hu ua PET fiber, uas yog nyob rau ntawm cov polymer compound. Tsim tawm hauv xyoo 1941, nws yog thawj thawj qhov loj ntawm cov hluavtaws. Qhov loj tshaj qhov zoo tshaj ntawm polyester fiber yog hais tias nws muaj zoo wrinkle tsis kam thiab duab kom zoo, thiab muaj lub zog loj thiab elastic rov qab muaj peev xwm. Nws yog qhov ruaj thiab ruaj khov, tiv thaiv tawv nqaij, tsis-kuag plaub hau, tsis nplaum plaub hau.
Polyester fiber muaj cov khoom zoo heev, xws li lub siab tawg lub zog thiab elastic modulus, tiv taus hnyav, zoo heev thaum tshav kub kub cov nyhuv, zoo tiv tshav kub thiab lub teeb kuj. Polyester fiber ntau muaj qhov chaw yaj li ntawm 255 ° C thiab lub khob hloov kub txog li 70 ° C. Nws ruaj khov nyob rau hauv cov duab nyob rau hauv ntau hom ntawm xaus-siv tej yam kev mob. Cov ntaub yog ntxuav thiab hnav. Ib qho ntxiv, nws muaj qhov ua tau zoo (xws li kev tiv taus cov organic solvents thiab xab npum). , Tshuaj tua kabmob, tshuaj dawb, oxidant) thiab zoo corrosion kuj, ruaj khov rau cov acids qaug zog, alkalis, thiab lwm yam, yog li nws muaj ntau cov kev siv thiab kev siv kev lag luam.
Txoj kev loj hlob sai ntawm kev lag luam roj av kuj tau muab cov khoom lag luam nplua nuj thiab pheej yig dua rau kev tsim cov tshuaj polyester. Ntxiv nrog rau kev tsim cov thev naus laus zis xws li tshuaj lom neeg, tshuab, thiab hluav taws xob tsis siv neeg tswj tshuab hauv xyoo tsis ntev los, cov khoom siv raw ntau lawm, fiber ntau tsim thiab ua cov txheej txheem tau maj mam ua tiav cov tshuaj fiber ntau, tas mus li, siv tshuab thiab ua nrawm, polyester fiber ntau tau dhau los ua kev loj hlob sai tshaj plaws thiab zoo tshaj plaws tsim hluavtaws fiber ntau. Xyoo 2010, kev tsim cov tshuaj fiber ntau thoob ntiaj teb ncav cuag 37.3 lab tons, xam txog 74% ntawm lub ntiaj teb' s tag nrho cov tshuaj fiber ntau.
