Dacron ndi mtundu wofunikira wa ulusi wopangira ndipo ndi dzina lamalonda la ulusi wa polyester ku China.Zimachokera ku oyengeka terephthalic acid (PTA) kapena dimethyl terephthalic acid (DMT) ndi ethylene glycol (MEG) monga zopangira, kupyolera mu esterification kapena transesterification ndi polycondensation reaction ndi kukonzekera polima - polyethylene terephthalate (PET), kupota ndi pambuyo- processing zopangidwa ndi fiber.Zomwe zimatchedwa polyester filament ndi kutalika kwa makilomita oposa makilomita a silika, ulusiwo umakhala mpira.Malinga ndi njira zosiyanasiyana zopangira, ulusi wa poliyesitala nthawi zambiri umagawidwa m'magulu atatu: ulusi woyamba, ulusi wotambasula ndi ulusi wopindika.
Makhalidwe a polyester filament
Mphamvu: Ulusi wa poliyesitala ndi wamphamvu kuwirikiza kawiri kuposa thonje komanso kuwirikiza katatu kuposa ubweya wa nkhosa, motero nsalu za poliyesitala zimakhala zolimba komanso zolimba.
Kutentha kukana: angagwiritsidwe ntchito mu -70 ℃ ~ 170 ℃, ndi yabwino kutentha kukana ndi bata matenthedwe ulusi kupanga.
Kutanuka: Kutanuka kwa poliyesitala kuli pafupi ndi ubweya, ndipo kukana kwa crease ndikwabwino kuposa ulusi wina.Nsaluyi ilibe makwinya ndipo imakhala ndi mawonekedwe abwino.
Kukana kuvala: Kukana kuvala kwa poliyesitala kumakhala kwachiwiri kwa nayiloni, m'malo achiwiri mu ulusi wopangira.
Mayamwidwe amadzi: Polyester imakhala ndi mayamwidwe ochepa amadzi komanso kuchuluka kwa chinyezi komanso magwiridwe antchito abwino.Komabe, chifukwa cha mayamwidwe amadzi otsika komanso magetsi osunthika kwambiri opangidwa ndi mikangano, mawonekedwe achilengedwe a utoto ndiwosauka.Chifukwa chake, poliyesitala nthawi zambiri imapakidwa utoto ndi kutentha kwambiri komanso utoto wambiri.
Kupaka utoto: Polyester palokha ilibe magulu a hydrophilic kapena magawo olandila utoto, kotero kuti utoto wa poliyesitala ndi woyipa, utha kupakidwa utoto wobalalika kapena utoto wosakhala wa ionic, koma mikhalidwe yopaka utoto ndi yovuta.
Kugwiritsa ntchito polyester filament
Polyester ngati chovala CHIKWANGWANI, nsalu yake pambuyo kutsuka kukwaniritsa zotsatira za sanali makwinya, sanali - ironing.Polyester nthawi zambiri imaphatikizidwa kapena kulumikizidwa ndi ulusi wosiyanasiyana, monga poliyesitala wa thonje, poliyesitala wa ubweya, ndi zina zotero, zomwe zimagwiritsidwa ntchito kwambiri muzovala zosiyanasiyana ndi zokongoletsera.Polyester angagwiritsidwe ntchito makampani conveyor lamba, hema, chinsalu, chingwe, ukonde nsomba, etc., makamaka tayala poliyesitala chingwe, amene ali pafupi nayiloni ntchito.Polyester angagwiritsidwenso ntchito zipangizo kutchinjiriza magetsi, asidi zosagwira fyuluta nsalu, mankhwala mafakitale nsalu, etc. Synthetic CHIKWANGWANI wakhala chimagwiritsidwa ntchito m'madera osiyanasiyana a chuma dziko chifukwa cha mphamvu zake mkulu, abrasion kukana, asidi kukana, alkali kukana, mkulu kukana kutentha, kulemera kopepuka, kutentha, kutchinjiriza kwamagetsi kwabwino komanso kukana mildew.
