Vim lub ntiaj teb no depletion ntawm cov peev txheej, tsev xog paj puas tsuaj rau ib puag ncig thiab lwm yam cuam tshuam rau tib neeg lub neej, tib neeg txoj kev paub txog ntsuab nyob tau zoo thiab zoo dua.Nyob rau hauv xyoo tas los no lo lus ntawm "regenerated / recycled raw khoom" tau txais kev nyiam nyob rau hauv khaub ncaws thiab tsev textile kev lag luam.Qee lub npe nrov thoob ntiaj teb hnav xws li Adidas, Nike, Uniqlo thiab lwm lub tuam txhab yog cov neeg tawm tswv yim ntawm qhov kev txav no.
Dab tsi yog regenerated cellulose fiber thiab regenerated polyester fiber?Ntau tus neeg tsis meej pem txog qhov no.
1. Dab tsi yog regenerated cellulose fiber ntau?
Raw khoom ntawm regenerated cellulose fiber yog ntuj cellulose (xws li paj rwb, hemp, xyoob, ntoo, shrubs).Txhawm rau tsim kom muaj kev ua tau zoo dua ntawm cov cellulose fiber ntau, peb tsuas yog xav tau hloov lub cev qauv ntawm ntuj cellulose.Nws cov qauv tshuaj tseem tsis hloov pauv.Txhawm rau muab tso rau hauv ib txoj kev yooj yim, regenerated cellulose fiber yog muab rho tawm thiab spined los ntawm cov khoom qub qub los ntawm kev siv thev naus laus zis.Nws belongs rau cov khoom siv fiber ntau, tab sis nws yog ntuj thiab txawv ntawm polyester fiber.Nws tsis yog tshuaj fiber ntau!
Tencel fiber, tseem hu ua "Lyocell", yog ib qho kev tsim kho cellulose fiber ntau hauv khw.Sib tov ntoo pulp ntawm tsob ntoo coniferous, dej thiab cov kuab tshuaj thiab cua sov kom txog thaum tiav dissolution.Tom qab de-impurity thiab spinning txheej txheem ntawm "Lyocell" cov khoom tiav lawm.Txoj hauv kev weaving ntawm Modal thiab Tencel zoo ib yam.Nws cov ntaub ntawv raw yog muab los ntawm cov ntoo qub.Xyoob fiber ntau muab faib ua xyoob ntoo fiber ntau thiab thawj xyoob fiber ntau.Xyoob pulp fiber yog tsim los ntawm kev ntxiv cov khoom siv ntxiv rau cov ntaub so ntswg ntawm Moso xyoob thiab ua tiav los ntawm kev ntub dej.Thaum thawj xyoob fiber ntau tau muab rho tawm los ntawm Moso xyoob tom qab kev kho mob lom neeg.
2, Dab tsi yog regenerated / recycled polyester fiber?
Raws li lub hauv paus ntsiab lus ntawm kev tsim dua tshiab, cov txheej txheem ntawm kev tsim tawm polyester fiber ntau tuaj yeem muab faib ua ob pawg: lub cev thiab tshuaj.Txoj kev siv lub cev txhais tau tias kev txheeb xyuas, tu thiab ziab cov khoom pov tseg polyester thiab tom qab ntawd yaj cov spinning ncaj qha.Thaum cov txheej txheem tshuaj yog hais txog depolymerizing pov tseg cov ntaub ntawv polyester rau polymerization monomer lossis polymerization intermediates los ntawm cov tshuaj tiv thaiv;regeneration polymerization tom qab purification thiab sib cais cov kauj ruam thiab ces yaj spinning.
Vim hais tias ntawm cov cuab yeej tsim khoom yooj yim, cov txheej txheem yooj yim thiab cov nqi tsim khoom qis ntawm lub cev, nws yog txoj hauv kev tseem ceeb los siv polyester hauv xyoo tas los no.Ntau tshaj 70% mus rau 80% ntawm lub peev xwm ntawm cov khoom siv polyester yog regenerated los ntawm lub cev txoj kev.Nws cov xov paj yog tsim los ntawm cov dej ntxhia dej pov tseg thiab cov fwj Coke.Nws yog qhov nrov heev hauv cov teb chaws tsim kho xws li Europe thiab Tebchaws Meskas vim nws tau rov qab siv cov pov tseg.Recycled polyester tuaj yeem txo kev siv roj, txhua tuj ntawm cov xov paj PET tiav tuaj yeem txuag tau 6 tons roj.Nws tuaj yeem pab txhawb kom txo cov pa phem thiab tswj lub tsev cog khoom.Piv txwv li: rov ua dua lub raj mis yas nrog lub ntim ntawm 600cc = carbon txo ntawm 25.2g = roj txuag ntawm 0.52cc = dej txuag ntawm 88.6cc.
Yog li cov khoom siv rov ua dua tshiab / rov ua dua tshiab yuav yog cov ntaub ntawv tseem ceeb uas tau nrhiav los ntawm tib neeg yav tom ntej.Ntau yam khoom uas cuam tshuam nrog peb lub neej xws li khaub ncaws, khau thiab rooj yog ua los ntawm cov khoom siv zoo ib puag ncig.Nws yuav zoo siab txais tos cov pej xeem ntau dua.
