RPET yog recycled polyethylene terephthalate, uas yog ib qho khoom zoo rau ib puag ncig.
Cov txheej txheem tsim khoom ntawm RPET yog tsim los ntawm cov khoom pov tseg polyester fibers, xws li cov hnab yas pov tseg. Ua ntej, ntxuav cov khib nyiab kom huv si thiab tshem tawm impurities. Tom qab ntawd zuaj thiab cua sov kom tig nws mus rau hauv cov khoom me me. Tom qab ntawd, cov khoom yog melted thiab regenerated, xim hmoov yog ntxiv, thiab stretched thiab refined los ntawm ib tug fiber spinning tshuab los tsim RPET fibers.
Kev tsim cov rPET T-shirts tuaj yeem muab faib ua plaub qhov txuas loj: cov khoom siv raw → fiber ntau → fabric weaving → npaj-rau-ua tiav.
1. Raw khoom rov qab thiab pretreatment
• Kev sau lub raj mis yas: Sau cov pov tseg PET lub raj mis los ntawm cov ntsiab lus rov ua dua hauv zej zog, lub khw muag khoom rov qab los yog cov chaw ua haujlwm rov ua dua tshiab (kwv yees li 14 lab tons ntawm PET lub raj mis tau tsim thoob ntiaj teb txhua xyoo, thiab tsuas yog 14% ntawm cov khoom siv rov ua dua tshiab).
• Ntxuav thiab crushing: Lub raj mis yas rov qab tau muab faib ua manually/mechanical (tshem cov impurities, tsis yog-PET cov ntaub ntawv), tshem tawm cov ntawv thiab lub kaus mom (feem ntau yog PE / PP cov ntaub ntawv), ntxuav thiab tshem tawm cov kua thiab stains, thiab ces crushed rau hauv 2-5cm fragments.
2. Fiber regeneration (RPET xov paj ntau lawm)
• Melt extrusion: Tom qab ziab, PET fragments yog rhuab mus rau 250-280 ℃ kom yaj, tsim ib tug viscous polymer yaj.
• Spinning molding: Lub yaj yog extruded rau hauv ib tug zoo kwj los ntawm cov tshuaj tsuag phaj, thiab tom qab txias thiab kho, nws ua ib tug recycled polyester luv fiber (los yog ncaj qha spun rau hauv ib tug nruam filament).
• Spinning: luv fibers yog tsim rau hauv RPET yarn los ntawm combing, striping, coarse yarn, fine yarn thiab lwm yam txheej txheem (zoo ib yam li tus thawj PET yarn txheej txheem, tab sis cov raw khoom yog recycled).
3. Npuag weaving thiab ua cov khaub ncaws
• Npuag weaving: RPET yarn yog ua los ntawm knitted ntaub los ntawm lub voj voog tshuab / transverse tshuab weaving (raws li tus txheej txheem ntawm cov ntaub polyester zoo tib yam), uas tuaj yeem ua rau ntau yam ntaub so ntswg xws li dawb, pique, ribbed, thiab lwm yam.
• Tom qab ua tiav thiab xaws: zoo ib yam li T-shirts zoo tib yam, nrog rau dyeing, txiav, luam ntawv, xaws (neckline rib / ntug), ironing thiab lwm yam, thiab thaum kawg ua RPET T-shirts.
RPET T-shirt yog ib yam khoom tsaws ntawm "kev lag luam yas rov ua dua tshiab". Los ntawm kev hloov cov yas pov tseg rau hauv khaub ncaws, nws yuav siv sij hawm rau hauv tus account ib puag ncig kev tiv thaiv kev xav tau thiab cov txiaj ntsig zoo.
