Kiliva polyester(polyethylene terephthalate) e polymerized mai le refined terephthalic acid (PTA) ma le ethylene glycol.O foliga vaaia o le araisa granular, ma e tele ituaiga (malamalama uma, afa malamalama, malamalama tele, cationic, lenei faʻaumatia).
I le maketi upusii o meataalo polyester, e masani ona e vaai i upu "malamalama tele", "semi-faaumatia" ma le "malamalama", lea o loo taʻua iinei mo le titanium dioxide (TiO2) mea i totonu o meataalo polyester, faaopoopo titanium dioxide (TiO2) i le liusuavai e faaitiitia ai le iila o le alava."Malamalama tele" (Yizheng chemical fiber e taʻua foi o le "super light") o mea o loʻo i totonu o le titanium dioxide i meataalo polyester e leai se mea;O le anotusi o le titanium dioxide i le fasi polyester "malamalama" e tusa ma le 0.1%;Ole mea ole titanium dioxide ile "semi-dull" polyester chip e (0.32±0.03)%;O le titanium dioxide i totonu o le pusa polyester "faʻaumatia atoa" e 2.4% i le 2.5%.
Faatasi ai ma le faʻatupulaia o le atinaʻeina o le tamaoaiga o le lalolagi ma le faʻateleina o le faʻaleleia o tulaga o le soifuaga o tagata, ua vave ona atiaʻe le pisinisi ie ma lavalava.Semi-dull polyester chip ua faʻaaogaina lautele mo lona lanu sili ona lelei, malosi maualuga ma mea e sili ona lelei le gaosiga, ma o le fanua talosaga o le a faʻalauteleina i lea aso ma lea aso, ma avea ma mea autu mo le filo ie, ata tifaga polyester, ma isi fanua.
E tusa ai ma le faʻaogaina o le fasi pepa e mafai ona vaevaeina i le fiber grade polyester fasi, fagu vasega polyester fasi ma ata tifaga vasega polyester fasi vaega e tolu.
Fiber grade polyester chips o lo'o fa'aogaina e gaosia ai le alava fa'atosina polyester ma le filament polyester, o mea mata'utia ia mo le fa'agaioia o alava ma oloa fa'atatau i pisinisi alava polyester.O pusa pusa polyester ua vaevaeina i ni vaega se lua o le copolymerization ma le homopolization, lea e mafai ona vaevaeina i fagu vai minerale, fagu inu carbonated, isi meaʻai ma mea faʻapipiʻi e tusa ai ma faʻaoga eseese.Talu mai le oʻo mai o le ata tifaga polyester i le 1950s, ona o le sili ona lelei o mea faʻainisinia, vailaʻau faʻamaʻi ma tulaga faʻamautu, ona o se ata eletise eletise ua vave ona atiaʻe ma faʻaaogaina lautele.Faatasi ai ma le atinaʻeina o fale gaosi oloa, o le faʻaogaina o le ata tifaga polyester ua faʻateleina vave.I tausaga talu ai nei, o le polyester film ua faʻaaogaina lautele i mea faʻapipiʻi, mea lomitusi, mea fau fale, mea faigaluega o le ofisa, mea maneta ma mea faʻataʻitaʻi ma isi tulaga lautele faʻapea foʻi ma fanua faʻatauvaʻa ma maualuga.
I le taimi nei, o le tele o polyester gaosi oloa e tasi le laasaga, PTA ma MEG polymerization e le o toe gaosia fasi fasi pepa, ae aveese le soʻotaga vavalalata e maua saʻo ai alava ma filament.O le semi-fa'aumatia i totonu o le fasi pepa e 60%, ae o le tipi e leai se maketi, leai se tauvaga, ma e manino le maketi.O le gaosiga o vai minerale ma isi fagu inu ma fasi pepa, o le gaosiga o loʻo i ai nei ua sili atu, o le lelei o le au gaosi e le tutusa.E tasi le tone o polyester e mafai ona sili atu i le 33,000 fagu.E le gata i lea, o le pepa toe faʻaaogaina, o lona uiga, o fagu palasitika otaota e toe faʻaaogaina ina ia maua ai le fiber, taugofie, taugofie, ma mama le siosiomaga.Ae o le fa'atauanaina e matua matuia tele, ma popole ina ne'i fa'aletonu le fa'atonuga o maketi.
