Ntau hom khoom siv rov siv dua cov khaub ncaws. Koj puas paub tias cov khaub ncaws rov qab mus rau qhov twg? Qee lub npe xaiv los hlawv cov khaub ncaws qub qub, thaum ntau lub khw muag khoom hauv tsev pub dawb rau cov cheeb tsam hauv Africa xav tau. Cov khaub ncaws hauv tsev tau zoo heev, nyob rau hauv txoj kab nrog kev zam, thiab ntawm tus nqi qis. Kev pub dawb yog sib npaug rau kev siv thib ob.
Tseem muaj kev pub dawb los ntawm Xianyu siv khaub ncaws hauv Xianyu App. Lawv yuav teev cov pawg thiab ntau npaum li cas uas yuav tsum tau ua rau cov haujlwm hauv cheeb tsam pub dawb, tab sis puas yog cov khaub ncaws tau mus rau cov neeg xav tau, lossis qhov kawg tshwm sim yog qhov ua tsis tau Tracked. Tsis tas li ntawd, muaj qee cov khaub ncaws rov ua dua tshiab hauv lub tebchaws uas tau muab pov tseg. Qee qhov, raws li kuv paub, tau rov ua dua thiab hloov pauv hauv cov khoom siv los ntawm qee cov tuam txhab pheej yig ntawm Pinduoduo. Ob leeg Levi's thiab Adidas tab tom txav mus rau lub hom phiaj ntawm 100% rov ua dua tshiab, tab sis tseem nyob rau theem kev sim. Tam sim no, kev lag luam rov ua dua tshiab tseem nyob rau theem uas cov ntaub ntawv tsis muaj pob tshab txaus.
Piv txwv li, H& M thov kom tau ua tiav 90% cov peev txheej rov qab los, tab sis nws yog qhov nyuaj rau cov neeg siv khoom kom paub txog txoj hmoo kawg ntawm cov khoom no.
Txhawm rau kom ua tiav cov ntaub ntawv pob tshab, peb yuav tsum siv thev naus laus zis blockchain los taug qab, tab sis nws tsis muaj txiaj ntsig los siv thev naus laus zis los taug qab cov khaub ncaws tsis zoo thiab pheej yig. Qhov tseeb tom qab qhov opacity no yog tias raws li kev txheeb cais, tsuas yog 1% ntawm cov khoom siv thiab cov khaub ncaws uas tau siv los tsim cov ntaub tshiab. Cov fibers uas twb muaj lawm yog qhov nyuaj rau kev ua tiav 100% rov ua dua tshiab, thiab cov fibers tshiab yuav tsum tau ntxiv los xyuas kom meej cov ntaub zoo. Nws tseem nyuaj heev rau rov siv cov ntaub qub qub rau hauv cov ntaub. Tshwj xeeb tshaj yog cov khoom siv ntuj tsim, xws li paj rwb, linen, tawv, ntaub plaub, thiab lwm yam. Yeej siv cov ntaub zoo nkauj, cov khoom siv rov ua dua tsuas yog 30-50%, thiab lwm qhov yog fiber ntau tshiab, thiaj li ua kom cov ntaub zoo.
Austrian npuag loj heev Lenzing npaj yuav nqis peev ntau dua 1 billion euros hauv ob peb xyoos tom ntej no txhawm rau nthuav tawm Lyocell (Lyocell, feem ntau hu ua" Tencel") fiber ntau. Lyocell yog ua los ntawm cov ntoo rov siv dua thiab siv cov paj rwb pov tseg. Cov ntaub tshiab no muaj qhov zoo ntawm ob cov ntaub ntawv no. Nws yog hnav-resistant, ruaj khov, xis thiab breathable, thiab muaj kev txhim kho degradation tus nqi kom tau raws li qhov xav tau ntawm kev txhim kho kom ruaj khov.
