Polyester npuag yog cov khoom siv hluavtaws ua los ntawm PTA, DMT, thiab MEG ua cov khoom siv raw, uas muaj qhov zoo ntawm kev ruaj khov, ruaj, elastic, thiab hnav-resistant. Nws yog dav siv hauv teb xws li khaub ncaws, kho kom zoo nkauj, thiab tsheb. Cov txheej txheem ntau lawm suav nrog spinning, winding, thiab tom qab ua tiav. Txawm hais tias nws muaj qhov tsis zoo xws li kev nqus dej tsis zoo thiab pilling yooj yim, nws qhov kev ua tau zoo txuas ntxiv los ntawm kev txhim kho cov txheej txheem thiab kev txhim kho cov khoom ntxiv.
Polyester ntaub, tseem hu ua polyester fiber, yog ib qho tseem ceeb ntawm ntau yam hluavtaws fibers nyob rau hauv lub ntiaj teb no niaj hnub no. Nws yog fiber ntau ua polymer ua los ntawm purified terephthalic acid (PTA) los yog dimethyl terephthalate (DMT) thiab ethylene glycol (MEG) los ntawm esterification los yog ester pauv thiab condensation tshwm sim, thiab ces spun thiab tom qab kho los tsim fibers.
Qhov zoo ntawm polyester ntaub yog ruaj khov thiab ruaj khov, tsis yooj yim deformed, hnav-tiv taus thiab ruaj khov, zoo ruaj khov, thiab zoo hluav taws xob rwb thaiv tsev kev ua tau zoo, nrog rau zoo tiv thaiv tshav ntuj thiab huab cua. Tsis tas li ntawd, qhov stretchiness, wrinkle tsis kam, zoo li qub, thiab hnav tsis kam ntawm polyester ntaub ua rau nws nyiam cov khoom siv los ua cov txiv neej thiab poj niam cov khaub ncaws, tshwj xeeb tshaj yog tsim rau cov ris tsho sab nrauv.
Muaj ntau hom polyester fabrics, uas tuaj yeem muab faib ua polyester fibers thiab rov siv dua fibers raws li raw cov ntaub ntawv. Polyester fibers kuj muaj xws li polyester filament thiab polyester staple, ntawm cov polyester filament xws li raw cov ntaub so ntswg, stretch silk, textured silk, thiab network silk, hos polyester staple muaj xws li paj rwb hom, ntaub plaub, thiab intermediate hom staple. Regenerated fibers yog fibers ua los ntawm polyester fwj, spinning khib nyiab, pulp, ntuj fibers, thiab lwm yam raw khoom tom qab ua. Cov khoom sib txawv ntawm polyester fabrics txhua tus muaj lawv tus yam ntxwv thiab siv.
Polyester npuag muaj ntau yam kev siv, tsis yog tsuas yog ua rau txiv neej thiab poj niam cov khaub ncaws, kho kom zoo nkauj sab hauv ntaub thiab ntaub pua plag, tab sis kuj siv dav hauv kev lag luam, kev kho mob, tub rog thiab lwm yam. Piv txwv li, polyester ntaub muaj ntau yam kev siv nyob rau hauv lub tshav pob ntawm cov khoom sab nraum zoov, xws li cov tsev pheebsuab, pw tsaug zog hnab, hiking khaub ncaws, thiab lwm yam, vim hais tias nws muaj zoo hnav tsis kam, wrinkle kuj, thiab yooj yim tu yam ntxwv. Tsis tas li ntawd, polyester fabrics kuj ua lub luag haujlwm tseem ceeb hauv kev lag luam automotive, xws li automotive seat fabrics, automotive interiors, etc. Nws zoo heev hnav tsis kam, muaj kuab paug tsis kam, thiab tu yooj yim ua rau nws xaiv rau cov khoom siv sab hauv tsheb.
Cov txheej txheem ntau lawm ntawm polyester ntaub muaj peb yam tseem ceeb: spinning, winding, thiab tom qab ua. Spinning yog cov txheej txheem txuas mus ntxiv thiab sib npaug xa cov polymerized polyester yaj mus rau lub thawv spinning los ntawm lub twj tso kua mis spinning, tom qab ntawd txau tawm ib qho zoo filament ntws los ntawm spinneret, thiab solidifying rau hauv filaments nyob rau hauv lub txias nyhuv ntawm sab tshuab cua. Coiling yog cov txheej txheem ntawm winding cov filaments uas tsim los ntawm cov txheej txheem spinning rau hauv cylindrical hlab ntawm ib tug tej yam zoo thiab muaj peev xwm rau cia, thauj, thiab tom qab ua. Tom qab kev ua tiav suav nrog cov txheej txheem xws li ncab, qhov chaw sov, thiab curling los txhim kho lub cev thiab cov tsos zoo ntawm polyester fabrics.
Kev ua tau zoo ntawm polyester fabrics yog cuam tshuam los ntawm cov yam xws li lawv cov qauv fiber ntau, fiber ntau morphology, thiab fiber ntau cross-sectional morphology. Piv txwv li, qhov siab dua qhov crystallinity thiab orientation ntawm polyester fibers, qhov zoo dua lawv cov khoom siv thiab thermal. Tsis tas li ntawd, kev nqus dej noo, ua pa, thiab dyeing zog ntawm polyester fabrics kuj tuaj yeem txhim kho los ntawm cov txheej txheem ntau lawm thiab cov khoom ntxiv.
Txawm li cas los xij, polyester fabrics kuj muaj qee qhov tsis zoo. Piv txwv li, nws muaj kev nqus dej tsis zoo, nws yooj yim rau hluav taws xob zoo li qub, nws yooj yim rau pilling, thiab nws yooj yim rau cov plua plav. Tsis tas li ntawd, polyester fabrics muaj cov cua sov tsis zoo thiab tsis haum rau kev siv mus ntev ntawm qhov kub thiab txias. Yog li ntawd, thaum siv polyester ntaub, nws yog ib qho tsim nyog yuav tau xyuam xim rau nws txoj kev tu thiab tu kom tsis txhob muaj cov teeb meem no.
Zuag qhia tag nrho, polyester ntaub yog ib qho kev ua tau zoo thiab ntau yam hluavtaws fiber ntau. Txawm hais tias nws muaj qee qhov tsis zoo, kev ua haujlwm ntawm polyester fabrics tau raug txhim kho tas li thiab ua tiav los ntawm kev txhim kho cov txheej txheem txuas ntxiv thiab kev tshawb fawb ntxiv thiab kev txhim kho. Nyob rau hauv lub neej yav tom ntej, nrog kev nce qib ntawm kev siv tshuab thiab tib neeg txoj kev nrhiav lub neej zoo, polyester fabrics yuav raug siv thiab tsim nyob rau hauv ntau qhov chaw.
