Polyester yog cov khoom siv hluavtaws ua los ntawm cov khoom siv petrochemical, feem ntau muab los ntawm cov roj av. Nws belongs rau tsev neeg ntawm polymers, uas yog tsim los ntawm ntev chains ntawm molecules. Cov ntaub ntawv feem ntau ntawm polyester yog polyethylene terephthalate (PET), uas yog tsim los ntawm cov tshuaj tiv thaiv ntawm ethylene glycol thiab terephthalic acid.
Raws li cov ntaub, polyester paub txog nws lub zog, durability, thiab tsis kam rau shrinking, stretching, thiab wrinkling. Nws cov fibers yog inherently hydrophobic, txhais tau tias lawv tua cov dej, uas pab txhawb rau nws ceev-qhuav zog thiab tiv thaiv mildew. Polyester tuaj yeem tsim rau hauv cov ntaub ntawv sib txawv thiab ua tiav, xws li ntawm du thiab silky mus rau ntau qhov chaw textured. Nws yog feem ntau sib xyaw nrog ntuj fibers zoo li paj rwb los ua ke cov txiaj ntsig ntawm ob qho khoom siv, xws li softness thiab breathability nrog durability thiab wrinkle kuj.
Polyester yog dav siv nyob rau hauv ntau yam kev siv, xws li khaub ncaws, khoom vaj khoom tsev, industrial fabrics, thiab ntim. Nws muaj nuj nqis rau nws tus nqi pheej yig, ntau yam, thiab kev saib xyuas qis, ua rau nws mus rau cov khoom siv hauv ntau qhov kev lag luam. Tsis tas li ntawd, polyester tuaj yeem rov ua dua tshiab, uas tau ua rau muaj kev nce ntxiv hauv nws cov khoom siv hauv ib puag ncig, tshwj xeeb tshaj yog cov khoom siv polyester (rPET).
