Polyester chips(polyethylene terephthalate) yakasvibiswa kubva kunatswa terephthalic acid (PTA) uye ethylene glycol.Chitarisiko chiri mupunga granular, uye kune akawanda marudzi (ese akajeka, hafu yechiedza, mwenje mukuru, cationic, kupera uku).
Mumusika quotation yepolyester chips, iwe unowanzo kuona mazwi ekuti "chiedza chikuru", "semi-extinction" uye "chiedza", ayo anotaurwa pano nezve titanium dioxide (TiO2) zvirimo mumachipisi epolyester, achiwedzera titanium dioxide (TiO2) mukunyunguduka ndiko kuderedza kupenya kwefiber."Chiedza chikuru" (Yizheng chemical fiber inonziwo "super light") zviri mukati metitanium dioxide mupolyester chips ndeye zero;Zvinyorwa zvetitanium dioxide mu "bright" polyester slice inenge 0.1%;Zvirimo zvetitanium dioxide mu "semi-dull" polyester chip ndeye (0.32±0.03)%;Iyo titanium dioxide yemukati mu "full extinction" polyester chip ndeye 2.4% kusvika 2.5%.
Nekuwedzera kuri kuita hupfumi hwenyika pamwe nekuvandudzwa kwemararamiro evanhu, indasitiri yemachira nembatya yakasimukira nekukurumidza.Semi-dull polyester chip yakashandiswa zvakanyanya mukudhayiwa kwayo, kusimba kwepamusoro uye zvakanakisa kugadzirisa zvivakwa, uye munda wekushandisa unozowedzerwa zuva nezuva, uye uve iwo makuru ezvigadzirwa zvemachira fiber, polyester maindasitiri firimu, uye mamwe minda.
Zvinoenderana nekushandiswa kwechimedu chinogona kukamurwa kuita fiber giredhi polyester chidimbu, bhodhoro giredhi polyester chidimbu uye firimu giredhi polyester slice mapoka matatu.
Fiber giredhi repolyester machipisi anoshandiswa kugadzira polyester staple fiber uye polyester filament, ari mbishi zvinhu zvekugadzira fiber uye zvine hukama zvigadzirwa zvepolyester fiber mabhizinesi.Bhodhoro regiredhi repolyester machipisi akakamurwa kuita mapoka maviri ecopolymerization uye homopolization, ayo anogona kukamurwa kuita mabhodhoro emvura yemaminerari, mabhodhoro echinwiwa checarbonated, zvimwe midziyo yechikafu uye zvekurongedza zvinoenderana nekushandiswa kwakasiyana.Kubva pakatanga firimu repolyester muma1950s, nekuda kwemaitiro ayo emagetsi, kupikisa kwemakemikari uye kugadzikana kwedimensional, sefirimu rekuvhara magetsi rakagadzirwa nekukurumidza uye rakashandiswa zvakanyanya.Nekuvandudzwa kweindasitiri yemidziyo yemumba, kushandiswa kwefirimu repolyester gobvu kwakawedzera nekukurumidza.Mumakore achangopfuura, firimu repolyester rave richishandiswa zvakanyanya mukurongedza zvinhu, zvekudhinda, zvekuvakisa, zvemuhofisi, magineti uye mafoto zvinhu uye zvimwe zvinhu zvechivanhu pamwe nekucheka-kumucheto uye yakakwirira-tech minda.
Parizvino, iwo makuru ekugadzira polyester idanho rimwe kugadzirwa, PTA uye MEG polymerization haichabudisi zvimedu, asi inosiya yepakati chinongedzo inoburitsa staple fiber uye filament.Iyo semi-kupera kwechimedu inoverengera makumi matanhatu muzana, asi simendi inotenderera haina musika, haina kukwikwidza, uye musika uri pachena.Kugadzirwa kwemvura yemaminerari uye mamwe mabhodhoro ekunwa ane zvimedu, kugadzirwa kwemazuva ano kwave kwakanyanyisa, hutano hwevagadziri hauna kufanana.Toni imwe yepolyester inogona kugadzira anopfuura 33,000 mabhodhoro.Pamusoro pezvo, pepa rakadzokororwa, kureva kuti, mabhodhoro epurasitiki akaraswa anodzokororwa kuti abudise staple fiber, mutengo wakaderera, mutengo wakaderera, uye kuchenesa nharaunda.Asi kubira zvisiri pamutemo kwakanyanyisa, kutyira kuti kana ramangwana rakanyorwa richakanganisa kurongeka kwemusika.
