Polyester anamva ndi zinthu zosunthika komanso zolimba zomwe zimagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana.Amapangidwa kuchokera ku ulusi wa polyester, womwe ndi ulusi wopangidwa womwe umapezeka kudzera munjira yotchedwa polyester spinning.Izi zimaphatikizapo polycondensation wa organic dibasic acid ndi dihydric mowa, zomwe zimapangitsa mapangidwe a polyethylene terephthalate (PET) fibers.

Chimodzi mwazabwino zazikulu za polyester amamva ndi kulekerera kwake kutentha kwambiri.Izi zimatha kupirira kutentha kwambiri popanda kutaya mawonekedwe ake kapena katundu.Amagwiritsidwa ntchito nthawi zambiri m'malo omwe kutentha kwambiri kumakhalapo, monga mu uvuni wamafakitale, ma injini zamagalimoto, ndi makina osefera.Kuthekera kwa polyester kukana kutentha kumapangitsa kukhala chisankho chabwino kwambiri pazogwiritsa ntchito izi, kuwonetsetsa kuti zimagwira ntchito kwanthawi yayitali ngakhale pamavuto.

Ubwino wina wa polyester umamveka ndikukana kwake kuvala ndi kuwala kwa dzuwa.Zinthuzi zimadziwika kuti zimakhala zolimba komanso zimatha kupirira kugwiritsidwa ntchito pafupipafupi popanda kuwonetsa zizindikiro za kuwonongeka.Kuphatikiza apo, polyester imamverera kuti imalimbana kwambiri ndi kuwonongeka kwa dzuwa.Izi zimapangitsa kukhala koyenera kwa ntchito zakunja komwe kukakhala padzuwa kwanthawi yayitali sikungapeweke.Polyester imamverera kuti ingagwiritsidwe ntchito pazinthu monga ma awnings, mipando yakunja, ndi zamkati zamagalimoto, zomwe zimateteza kwambiri kuti zisawonongeke komanso kuwonongeka chifukwa cha kuwala kwa dzuwa.

Polyester yomverera ndiyoyeneranso kugwiritsa ntchito kutentha kowuma.Mphamvu zake zolimbana ndi chinyezi zimapangitsa kukhala chisankho choyenera kwa malo omwe kutentha kowuma kumakhala kofala.Ikhoza kupirira bwino kutentha ndi chinyezi chochepa popanda kutaya kukhulupirika kwake.Izi zimapangitsa kuti poliyesitala ikhale yoyenera kugwiritsidwa ntchito m'mafakitale monga kupanga chitsulo ndi zitsulo, kupanga magalasi, ndi maziko.

Kuphatikiza pa kutentha kwake ndi kukana kuvala, polyester anamva ndi chinthu chabwino kwambiri chosonkhanitsira dothi.Kapangidwe kake kolimba komanso kamangidwe kake kokhomeredwa ndi singano kumapangitsa kuti igwire bwino fumbi, litsiro, ndi tinthu tina tambirimbiri.Izi zimapangitsa kukhala chisankho chodziwika bwino pantchito zotsuka, zamagalimoto, ndi zopanga.Zosefera za polyester nthawi zambiri zimagwiritsidwa ntchito muzosefera zafumbi, zoyeretsa mpweya, ndi matumba otsuka vacuum kuti zitsimikizire kusonkhanitsa ndi kusefa koyenera.

Ponseponse, polyester yomverera imapereka zabwino zambiri zomwe zimapangitsa kukhala chisankho chokondedwa m'mafakitale osiyanasiyana.Kulekerera kwake kutentha kwakukulu, kukana kuvala ndi kuwala kwa dzuwa, kuyenerera kwa ntchito zotentha zowuma, ndi zinthu zabwino kwambiri zosonkhanitsa dothi zimapangitsa kukhala chinthu chodalirika komanso chosunthika.Kaya imagwiritsidwa ntchito m'malo otentha kwambiri, panja, kapena kuti malo antchito azikhala aukhondo, poliyesitala imamveka ngati yankho lolimba komanso logwira ntchito.Ndi maubwino ake osiyanasiyana, sizodabwitsa kuti poliyesitala idakhalabe yotchuka m'mafakitale padziko lonse lapansi.
