Dacron yog ib qho tseem ceeb ntawm cov hluavtaws fiber ntau thiab yog lub npe lag luam ntawm polyester fiber hauv Suav teb.Nws yog ua raws li refined terephthalic acid (PTA) los yog dimethyl terephthalic acid (DMT) thiab ethylene glycol (MEG) raws li raw cov ntaub ntawv, los ntawm esterification los yog transesterification thiab polycondensation cov tshuaj tiv thaiv thiab kev npaj ntawm polymer - polyethylene terephthalate (PET), spinning thiab post- ua los ntawm fiber ntau.Lub thiaj li hu ua polyester filament yog qhov ntev ntawm ntau tshaj li kilometers ntawm txhob lo lo ntxhuav, filament qhov txhab rau hauv ib lub pob.Raws li cov txheej txheem ntau lawm, polyester filament feem ntau muab faib ua peb pawg: thawj filament, stretch filament thiab deformation filament.
Cov yam ntxwv ntawm polyester filament
Lub zog: Polyester fibers yog ze li ob npaug ntawm cov paj rwb thiab peb zaug muaj zog li ntaub plaub, yog li polyester fabrics muaj zog thiab ruaj khov.
Thaum tshav kub kub tsis kam: tuaj yeem siv hauv -70 ℃ ~ 170 ℃, yog qhov zoo tshaj plaws tshav kub tsis kam thiab thermal stability ntawm hluavtaws fibers.
Elasticity: Lub elasticity ntawm polyester yog ze rau cov ntaub plaub, thiab lub crease kuj zoo dua lwm cov fibers.Cov ntaub yog wrinkle-dawb thiab muaj zoo zoo tuav.
Hnav tsis kam: Polyester hnav tsis kam yog qhov thib ob rau nylon, nyob rau hauv qhov chaw thib ob hauv cov khoom siv hluavtaws.
Kev nqus dej: Polyester muaj qhov nqus dej tsawg thiab noo noo rov qab tus nqi thiab kev ua haujlwm zoo rwb thaiv tsev.Txawm li cas los xij, vim tias qhov nqus dej tsawg thiab cov hluav taws xob zoo li qub uas tsim los ntawm kev sib txhuam, lub ntuj adsorption kev ua tau zoo ntawm cov xim tsis zoo.Yog li ntawd, polyester feem ntau yog dyed los ntawm kub kub thiab siab dyeing.
Dyeing: Polyester nws tus kheej tsis muaj cov pab pawg hydrophilic lossis dye acceptor qhov chaw, yog li cov dyeing ntawm polyester tsis zoo, tuaj yeem dyed nrog disperse dyes lossis non-ionic dyes, tab sis cov dyeing tej yam kev mob hnyav.
Kev siv cov polyester filament
Polyester ua cov khaub ncaws fiber ntau, nws cov ntaub tom qab ntxuav kom ua tiav cov nyhuv ntawm tsis-wrinkle, tsis-ironing.Polyester feem ntau yog sib xyaw lossis cuam tshuam nrog ntau yam fibers, xws li paj rwb polyester, ntaub plaub polyester, thiab lwm yam, dav siv ntau yam khoom siv khaub ncaws thiab cov ntaub ntawv zoo nkauj.Polyester tuaj yeem siv rau hauv kev lag luam rau conveyor siv, tsev pheebsuab, canvas, cable, nuv ntses net, thiab lwm yam, tshwj xeeb tshaj yog rau cov log tsheb polyester qaum, uas yog ze rau nylon hauv kev ua tau zoo.Polyester kuj tseem siv tau rau hauv cov khoom siv hluav taws xob rwb thaiv tsev, acid-resistant lim ntaub, cov ntaub ntawv kev lag luam tshuaj, thiab lwm yam. hluavtaws fiber ntau tau dav siv nyob rau hauv ntau yam kev lag luam hauv lub teb chaws vim nws lub zog siab, abrasion tsis kam, acid tsis kam, alkali tsis kam, siab. kub tsis kam, lub teeb yuag, sov so, zoo hluav taws xob rwb thaiv tsev thiab mildew kuj.
