Kev loj hlob ntawm lub ntiaj teb nokev lag luam textilesaw tau nce ib tus neeg txhua xyoo textile noj los ntawm 7kg mus rau 13kg, nrog rau tag nrho cov ntim ntawm ntau tshaj 100 lab tons, thiab txhua xyoo cov khoom pov tseg textiles tau mus txog 40 lab tons. Xyoo 2020, thaj av loj hauv kuv lub tebchaws yuav rov ua dua 4.3 lab tons ntawm textiles, thiab cov khoom siv tshuaj fiber ntau yuav ntau dua 60 lab tons. Txawm hais tias tus naj npawb ntawm textile exports siab, tus nqi rov ua dua yog tsawg. Tseem muaj ntau dua 2/3 ntawm cov ntaub ntawv pov tseg hauv ntiaj teb uas tsis tuaj yeem hloov kho thiab rov ua dua tshiab.

Lub npe hu ua renewable textiles feem ntau suav hais tias yuav rov siv duatextilesuas tuaj yeem rov siv dua, thiab kev ua haujlwm ntawm cov khoom siv rov ua dua tshiab yog qhov qub, thiab txawm tias muaj txiaj ntsig ntau duaib cov ntaub. Rau biodegradable "tso pov tseg" cov khoom siv textile, uas tsis muaj kev lag luam muaj txiaj ntsig ntawm kev rov qab los sai, lawv tuaj yeem muab pov tseg. Ntxiv nrog rau lub tswv yim no ntawm kev lag luam ncig, kev lag luam thev naus laus zis faib rov ua dua ua ob hom: kev kho dua tshiab thiab kev txo qis.

Textile recycling txoj kev feem ntau muaj xws li mechanical, lub cev thiab tshuaj txoj kev. Cov txheej txheem siv tshuab yog ua cov ntaub ntawv rau hauv nyias strips los yog fibers rau re-spinning lossis hloov lub hom phiaj tseem ceeb ntawm textiles; lub cev txoj kev yog tsuas yog rau cov hluavtaws fibers, tshwj xeeb tshaj yog cov fibers tsim los ntawm yaj spinning, uas yog melted nyob rau hauv high kub los ua textiles yaj. Tom qab lim impurities, lawv tuaj yeem spun lossis siv rau lwm yam khoom. Qee cov khoom siv fiber ntau zoo tuaj yeem tshem tawm epoxy resin ntawm qhov kub thiab txias, rov ua dua lub xeev fiber ntau, thiab siv rau hauv cov khoom tsis yog textile los ntawm kev txiav thiab crushing; chemical txoj kev yog tsuas yog rau ntau yam textiles. Kev sib cais ntawm cov fibers yog rov ua dua tshiab, thiab ntau zaus yog siv los ntxuav cov khoom siv rov ua dua tshiab, tshem tawm cov impurities thiab dyes zoo dua, thiab siv kev txhim kho thiab rov tsim dua tshiab.

Xyoo 2020, kuv lub teb chaws cov khoom siv polyester fiber ntau yog 49.3575 lab tons, suav txog 72% ntawm tag nrho, paj rwb yog 8.6 lab tons, suav txog 12%, viscose yog 3.95 lab tons, suav txog 5.8%, nylon suav txog 5.6%. Cov fibers ntxiv ntxiv txog li 4%. Txhawm rau kom ntseeg tau cov khoom noj khoom haus, cov khoom tsim tawm ntawm cov fibers ntuj xws li paj rwb, linen, thiab ntaub plaub yog nyob rau hauv ib qho kev poob qis tag nrho. Nws yog lub tswv yim phased los hloov qee qhov ntuj fibers nrog hluavtaws fibers. Lub hauv paus ntawm cov khoom siv hluavtaws fiber ntau tuaj yeem xaiv cov khoom siv bio-based, thiab cov khoom siv rov ua dua tshiab yuav tsum tau siv los maj mam tshem tawm qhov kev cia siab ntau dhau ntawm cov peev txheej uas tsis yog txuas ntxiv dua tshiab. Qhov no tsis yog tsuas yog qhov tseem ceeb ntawm kev txuag cov peev txheej, tiv thaiv ib puag ncig thiab txo kev ua haujlwm ntawm cov av cog qoob loo, tab sis kuj tseem ceeb heev rau kev tsim kho thiab kev loj hlob ntawm kev lag luam ncig.
