Kev txhim kho ntawm lub ntiaj tebTextile Kev Lag Luam Textilechain has increased the per capita annual textile consumption from 7kg to 13kg, with a total volume of more than 100 million tons, and the annual production of waste textiles has reached 40 million tons. Hauv 2020, lub teb chaws tseem ceeb hauv kuv lub tebchaws yuav rov qab siv dua 4.3 lab tons ntawm textiles, thiab cov zis ntawm cov hmoov lom neeg yuav ntau dua 60 lab tons. Txawm hais tias tus naj npawb ntawm cov ntawv xa tawm yog qhov siab, tus nqi rov ua dua tshiab. Tseem tshuav ntau dua 2/3 ntawm cov khib nyiab textiles hauv lub ntiaj teb uas tsis tau hloov kho dua tshiab thiab rov ua dua tshiab.

Lub npe hu ua txuas ntxiv yog feem ntau suav tias yuav rov ua dua tshiabtsev luam ntawvuas tuaj yeem rov siv dua, thiab kev ua yeeb yam ntawm cov khoom lag luam Remanufactured yog qhov zoo ib yam, thiab txawm muaj nqi ntau duaIb LeegCov. Rau biodegradable "cov khoom siv tam sim" textile, uas tsis muaj tus nqi nyiaj txiag ntawm kev rov ua haujlwm sai, lawv tuaj yeem yog cov nplooj lwg av. Ntxiv nrog rau cov tswv yim no ntawm kev lag luam ncig, kev lag luam technology muaj kev ua dua tshiab ua ob hom: txhim kho thiab downgrading.

Textile recycling kev feem ntau suav nrog kev siv tshuab, kev siv lub cev thiab tshuaj lom neeg. Cov txheej txheem neeg ua haujlwm yog ua cov txheej txheem rau hauv nyias ib daim hlab lossis cov poj niam rau rov qab rov qab lossis hloov lub hom phiaj tseem ceeb; Lub cev nqaij daim tawv yog tsuas yog rau cov khoom siv hluavtaws, tshwj xeeb tshaj yog cov fibers tsim los ntawm Melt Spinning, uas tau melted ntawm qhov kub kom ua rau cov ntawv nyeem melt. Tom qab lim impurities, lawv tuaj yeem spun lossis siv nyob rau hauv lwm cov khoom. Qee cov khoom siv siab fiber ntau tuaj yeem tshem tawm epoxy resin ntawm qhov kub lub xeev, thiab siv rau cov khoom lag luam tsis los ntawm kev txiav thiab cov txheej txheem sib tsoo; Tshuaj lom neeg siv tshuaj yog feem ntau rau ntau yam ntawm textiles. Kev sib cais ntawm cov fibers yog siv cais, thiab ntau zaus siv los ua kom huv cov khoom siv ua rov ua dua, zoo dua cov impurities thiab dyes, thiab ua kev txhim kho thiab tsim dua tshiab.

Hauv 2020, kuv lub teb chaws cov lus tso zis fiber ntau yog 49.3575 lab tons, suav rau 7,6 lab yog 3.95 lab rau 5.8%, nylon nyiaj rau 5.6%. Cov seem uas tshuav ntxiv ntxiv txog li 4%. Txhawm rau kom ua tau zaub mov noj, cov zis tawm ntawm cov zaub mov ntuj xws li paj rwb, linen, thiab cov ntaub plaub yog nyob ntawm ib qho qis dua ib yam nkaus. Nws yog cov phased lub tswv yim los hloov qee cov khoom ntuj nrog cov khoom siv hluavtaws. Lub hauv hluavtaws fiber ntau cov ntaub ntawv tuaj yeem xaiv cov khoom siv xyoob ntoo muaj peev xwm xaiv cov khoom siv txuas ntxiv mus ntxiv rau cov chaw pabcuam ntau dhau ntawm cov khoom siv tsis-tshiab. Qhov no tsis yog ntawm kev ua tau zoo tseem ceeb rau kev txuag cov peev txheej, tab sis kuj tseem muaj qhov tseem ceeb rau kev tsim kho thiab kev txhim kho kev lag luam.
