Kev ua qias tuaj hauv kev lag luam textile
● Sun Ruizhe, tus thawj tswj hwm ntawm Tuam Tshoj National Textile and Apparel Council, tau hais ib zaug ntawm Climate Innovation and Fashion Summit hauv xyoo 2019 tias kev lag luam textile thiab garment tau dhau los ua kev lag luam ua qias tuaj thib ob hauv ntiaj teb, thib ob tsuas yog kev lag luam roj;
● Raws li cov ntaub ntawv los ntawm Tuam Tshoj Circular Economy Association, kwv yees li 26 lab tons ntawm cov khaub ncaws qub raug pov rau hauv cov thoob khib nyiab hauv kuv lub tebchaws txhua xyoo, thiab tus lej no yuav nce mus txog 50 lab tons tom qab xyoo 2030;
● Raws li kev kwv yees ntawm Tuam Tshoj National Textile thiab Apparel Council, kuv lub teb chaws pov tseg cov ntaub pov tseg txhua xyoo, sib npaug li 24 lab tons ntawm cov roj av nyoos. Tam sim no, feem ntau cov khaub ncaws qub tseem raug pov tseg los ntawm qhov chaw pov tseg lossis hlawv, ob qho tib si yuav ua rau muaj kuab paug rau ib puag ncig.
Kev daws teeb meem rau kev ua qias tuaj - cov fibers bio-based
Cov xov paj rwb hauv cov ntaub feem ntau yog ua los ntawm cov khoom siv roj av, xws li polyester fibers (polyester), polyamide fibers (nylon lossis nylon), polyacrylonitrile fibers (acrylic fibers), thiab lwm yam.
● Nrog rau qhov tsis txaus ntawm cov peev txheej roj thiab kev paub txog kev tiv thaiv ib puag ncig ntawm cov neeg. Tsoomfwv kuj tau pib siv ntau yam kev ntsuas los txo kev siv cov peev txheej roj thiab nrhiav cov peev txheej rov ua dua tshiab uas zoo rau ib puag ncig los hloov.
● Vim muaj roj tsawg thiab teeb meem ib puag ncig cuam tshuam, cov teb chaws tsim cov tshuaj fiber ib txwm muaj xws li Tebchaws Meskas, European Union, thiab Nyiv Pooj tau maj mam thim rov qab los ntawm kev tsim cov tshuaj fiber ib txwm muaj, thiab tau tig mus siv cov bio-based fibers uas muaj txiaj ntsig zoo dua thiab tsis tshua cuam tshuam los ntawm cov peev txheej lossis ib puag ncig.
Cov ntaub ntawv polyester bio-based (PET/PEF) siv tau rau hauv kev tsim cov fibers bio-based thiabtawv nqaij biobased.
Hauv daim ntawv tshaj tawm tshiab kawg ntawm "Textile Herald" ntawm "Kev Tshuaj Xyuas thiab Kev Cia Siab ntawm Kev Siv Tshuab Textile Thoob Ntiaj Teb", nws tau taw qhia tias:
● 100% bio-based PET tau ua tus thawj coj hauv kev nkag mus rau hauv kev lag luam khoom noj khoom haus, xws li Coca-Cola dej haus, Heinz zaub mov, thiab cov ntim khoom ntxuav, thiab kuj tau nkag mus rau hauv cov khoom fiber ntawm cov npe nrov kis las xws li Nike;
● Cov khoom lag luam PET uas yog bio-based 100% lossis bio-based PEF T-shirt tau pom muaj nyob rau hauv kev ua lag luam.
Thaum tib neeg txoj kev paub txog kev tiv thaiv ib puag ncig txuas ntxiv mus, cov khoom siv bio-based yuav muaj cov txiaj ntsig zoo hauv kev kho mob, khoom noj thiab cov khoom kho mob uas muaj feem cuam tshuam nrog tib neeg lub neej.
● kuv lub teb chaws "Txoj Kev Npaj Txhim Kho Kev Lag Luam Textile (2016-2020)" thiab "Kev Lag Luam Textile" Kaum Peb Tsib Xyoos Txoj Kev Npaj" Kev Tshawb Fawb thiab Kev Txhim Kho Kev Siv Tshuab tau qhia meej tias qhov kev taw qhia ua haujlwm tom ntej yog: tsim cov khoom siv fiber tshiab los hloov cov peev txheej roj av, los txhawb kev lag luam ntawm cov fibers bio-based marine.
Cov fiber bio-based yog dab tsi?
● Cov fibers uas ua los ntawm cov kab mob hauv lub cev yog cov fibers uas ua los ntawm cov tsiaj txhu uas muaj sia nyob lossis lawv cov extracts. Piv txwv li, polylactic acid fiber (PLA fiber) yog ua los ntawm cov khoom ua liaj ua teb uas muaj hmoov txhuv nplej siab xws li pob kws, nplej, thiab beet qab zib, thiab alginate fiber yog ua los ntawm algae xim av.
● Hom fiber no tsis yog tsuas yog ntsuab thiab zoo rau ib puag ncig xwb, tab sis kuj muaj kev ua tau zoo heev thiab muaj nqis ntxiv ntau dua. Piv txwv li, cov khoom siv kho tshuab, biodegradability, wearability, non-flammability, tawv nqaij-phooj ywg, antibacterial, thiab noo noo-wicking zog ntawm PLA fibers tsis qis dua cov ntawm cov fibers ib txwm muaj. Alginate fiber yog cov khoom siv raw zoo rau kev tsim cov ntaub qhwv kho mob hygroscopic heev, yog li nws muaj txiaj ntsig tshwj xeeb hauv kev kho mob thiab kev noj qab haus huv. xws li, peb muaj cov khoom siv tshiab hu uatawv nqaij biobased / tawv nqaij vegan.
Vim li cas ho sim cov khoom rau cov ntsiab lus biobased?
Raws li cov neeg siv khoom nyiam cov khoom lag luam uas zoo rau ib puag ncig, muaj kev nyab xeeb, thiab cov khoom siv los ntawm cov nroj tsuag. Qhov kev thov rau cov fibers bio-based hauv kev lag luam textile nce ntxiv txhua hnub, thiab nws yog qhov tseem ceeb heev uas yuav tsum tsim cov khoom uas siv cov khoom siv bio-based ntau kom tau txais txiaj ntsig zoo hauv kev ua lag luam. Cov khoom siv bio-based xav tau cov ntsiab lus bio-based ntawm cov khoom txawm tias nws nyob hauv kev tshawb fawb thiab kev txhim kho, kev tswj xyuas zoo lossis kev muag khoom. Kev sim bio-based tuaj yeem pab cov chaw tsim khoom, cov neeg faib khoom lossis cov neeg muag khoom:
● Kev Tshawb Fawb thiab Kev Txhim Kho Khoom: Kev sim tshuaj lom neeg yog ua tiav thaum lub sijhawm tsim khoom siv lom neeg, uas tuaj yeem ua kom meej cov ntsiab lus ntawm cov khoom siv lom neeg kom yooj yim txhim kho;
● Kev tswj xyuas zoo: Thaum lub sijhawm tsim cov khoom siv bio-based, kev sim bio-based tuaj yeem ua tiav rau cov khoom siv raw uas tau muab los tswj xyuas qhov zoo ntawm cov khoom siv raw;
● Kev Txhawb Nqa thiab Kev Lag Luam: Cov ntsiab lus bio-based yuav yog ib qho cuab yeej lag luam zoo heev, uas tuaj yeem pab cov khoom lag luam kom tau txais kev ntseeg siab ntawm cov neeg siv khoom thiab ntes cov cib fim ua lag luam.
Kuv yuav ua li cas thiaj paub cov ntsiab lus biobased hauv ib yam khoom? - Kev xeem Carbon 14
Kev kuaj Carbon-14 tuaj yeem sib txawv ntawm cov khoom siv bio-based thiab cov khoom siv petrochemical hauv ib yam khoom. Vim tias cov kab mob niaj hnub no muaj carbon 14 tib yam li cov carbon 14 hauv huab cua, thaum cov khoom siv petrochemical tsis muaj carbon 14.
Yog tias qhov tshwm sim ntawm kev sim bio-based ntawm cov khoom yog 100% bio-based carbon cov ntsiab lus, nws txhais tau tias cov khoom yog 100% bio-sourced; yog tias qhov tshwm sim ntawm kev sim ntawm cov khoom yog 0%, nws txhais tau tias cov khoom yog petrochemical tag nrho; yog tias qhov tshwm sim ntawm kev sim yog 50%, Nws txhais tau tias 50% ntawm cov khoom yog los ntawm biological thiab 50% ntawm cov pa roj carbon yog los ntawm petrochemical.
Cov qauv xeem rau cov ntaub suav nrog tus qauv Asmeskas ASTM D6866, tus qauv European EN 16640, thiab lwm yam.
