Thaum lub khob yog cov khoom siv tseem ceeb hauv lub raj mis hauv xyoo pua dhau los, txij li xyoo 1980s, PET tau nyiam los ntawm cov tuam txhab thiab cov neeg siv khoom.Cov fwj "polyester" no muaj qhov tshwj xeeb zoo ntawm kev sib sib zog nqus thiab zoo li tsis tawg.Txawm li cas los xij, kev vam meej coj nrog nws cov kev cov nyom tshiab cuam tshuam nrog kev rov ua dua txhua xyoo ntawm ntau lab lub raj mis pov tseg.
Hloov cov fwj siv rau hauv cov khoom siv raw yuav tsum muaj cov txheej txheem ntev thiab nyuaj.Nws tag nrho pib nrog sau lub raj mis thiab nias rau hauv bales.Tom qab ntawd, cov bales yog qhib, sorted thiab crushed.Lub resulting flakes yog ntxuav (txias thiab kub) thiab sib cais los ntawm polyolefin los ntawm lub hau thiab liner.Tom qab ziab thiab sib cais cov hlau, cov flakes tuaj yeem ntim rau hauv silos lossis hnab loj.Lub voj voog tshiab pib.
Ib qho ntawm cov txheej txheem tseem ceeb rau kev tau txaisRecycled polyester yog spinning ntawm luv fibers,uas tuaj yeem siv tau, piv txwv li, hauv spinning, textile fillers lossis nonwovens.Cov ntawv thov no tau tsim tau zoo, nrog cov tsho woolen thiab shawls yog cov piv txwv tseem ceeb.
Tsis tas li ntawd, kev sau thiab rov ua dua tshiab ntawm lub raj mis yas yog nce thoob ntiaj teb vim muaj ntau yam.Yog li nws yog lub sijhawm los tshawb nrhiav cov kev xaiv siv kawg tshiab rau kev siv PET.
PET fibers muaj ntau yam zoo thaum siv hauv cov ntaub pua plag, nrog rau cov stain tsis kam, txawm tias zoo dua li tshuaj PA BCF.Tsis tas li ntawd, PET tuaj yeem molded undyed, thaum PP tsis tuaj yeem.Cov xov paj tsis muaj dyed tuaj yeem twisted, kub-teeb, dyed thiab stitched, los yog cov ntaub pua plag tiav tuaj yeem luam tawm.
Covkev tsim cov filaments tsis tu ncualos ntawm R-PET kuj tseem nyuaj dua li kev tsim cov fibers luv.Hauvfilament spinning, qhov zoo ntawm cov xov paj yog txiav txim siab los ntawm homogeneity ntawm cov khoom siv raw.Cov flakes rov qab los yog qhov tsis txaus ntseeg thiab qhov sib txawv me me hauv qhov zoo tuaj yeem ua rau muaj kev nce hauv cov xov hlau tawg lossis cov xov hlau tawg.Tsis tas li ntawd, qhov sib txawv ntawm flake zoo tuaj yeem cuam tshuam cov xim nqus ntawm cov yarns, uas ua rau streaks ntawm cov ntaub pua plag tiav.
Cov P-PET flakes ntxuav tau qhuav thiab ntxuav hauv lub reactor, melted nyob rau hauv ib tug extruder thiab ces dhau los ntawm ib tug loj cheeb tsam lim ntawm txawv fineness.Tom qab ntawd lub siab zoo yaj yog xa mus rau lub spinning system.High-quality spinning packs, double-hull rub rolls, HPc texturing systems, thiab plaub-log tsav winders tsim cov yarns thiab cua lawv mus rau spools.Raws li cov chaw tsim khoom, cov kab ntau lawm tau ua tiav hauv tebchaws Poland.
