Ndi kusintha kwa moyo ndi chitukuko cha sayansi ndi luso lamakono, zomwe anthu amafuna kuti akhale ndi moyo wabwino zikukwera, ndipo chidwi chowonjezereka chikuperekedwa ku chitetezo cha chilengedwe ndi moyo wathanzi.Ngakhale ulusi, chinthu chaching'ono kwambiri m'moyo, timayesetsanso kuteteza chilengedwe komanso kukhazikika.Choncho, padzakhala mankhwala mongamwachibadwa degradable PLA filament, zobiriwira zopangira thonje, etc.
Pali zikwizikwi za ulusi wosiyanasiyana pamsika.Ndiye mungadziwe bwanji kuti ndi mipira ya ulusi iti yomwe ili yabwino komanso yomwe imaipitsa dziko lathu?Lero tikambirana za kusankha kwa ulusi wokonda zachilengedwe.
1.Zingwe Zachilengedwe / Zomera Zomera
Lamulo loyamba logulira ulusi woluka wokonda zachilengedwe ndikupeza ulusi wotsatirawu.
- Ulusi wachilengedwe.Ulusi wopangidwa ndi anthu ndi wopangidwa ndi mafuta ndi mankhwala ambiri ndipo uyenera kupewedwa.
- Ndi biodegradable, kutanthauza kuti ngati itayikidwa mu mulu wa kompositi kapena mulu wa zinyalala, ulusiwo uwola kukhala manyowa.
- Kugula kwanuko.Ngati zingatheke, ndi bwino kugula ulusi kwanuko kuti muchepetse mpweya wowonjezera kutentha panthawi ya mayendedwe.
- Yang'anani ulusi wotsimikizika wa GOTs.GOTS imayimira Global Organic Textile Standard.
- Ulusi wobwezerezedwanso ukhoza kubwezeretsedwanso kuti ulusi wina wopangidwawo usatayike.
Kodi ulusi wonse wachilengedwe ndi wokhazikika?
Ulusi wachilengedwe umamveka bwino, koma kodi izi ndi zolondola nthawi zonse?Ayi, mwatsoka, sichoncho.Ulusi wachilengedwe ukhoza kuphimbidwa ndi pulasitiki kuti ukhale wofewa.
Ulusi wa zomera monga thonje ndi nsungwi nthawi zambiri zimamera ndi mankhwala ophera tizilombo omwe amawononga dziko lapansi, kuwononga magwero a madzi komanso kuvulaza nyama zakutchire ndi anthu.Thonje nthawi zambiri imachokera ku zomera zomwe zathandizidwa ndi GMO (transgenic organisms).
Ulusi wa zinyama ndi zomera zimatsukidwa ndi mankhwala ndi kuzipaka ndi mankhwala omwe angakhale ovulaza kwa ogwira ntchito ndi ogula.
Komabe, kufufuza100% ulusi wachilengedwendi chiyambi chabwino!
2. Ulusi Wowonongeka
Ngati ulusiwo uli ndi 100% ulusi wachilengedwe, uyenera kukhala wosawonongeka.Tsoka ilo, ulusi nthawi zambiri amachapidwa ndi kudayidwa ndi mankhwala, zomwe zimapangitsa kuti ulusiwo ukhale wosayenerera kupanga kompositi chifukwa mankhwalawo amatha kuwononga nthaka ndi madzi.
3. Ulusi Wobwezerezedwanso
Nthawi zonse ndikwabwino kusankha ulusi wobwezerezedwanso kuposa ulusi wopangidwa kuchokera pachimake.Imapulumutsa zida zopangira kuchokera kudzala lathu ndikuwapatsa moyo wachiwiri.
4. Ulusi Wopanga kapena Ulusi Wopanga
Kupanga ulusi wopangidwa kumagwiritsa ntchito mafuta ambiri.Chifukwa fiber imapangidwa ndi petrochemicals.Mafuta a petrochemical ndi mankhwala opangidwa kuchokera ku petroleum.Izi sizabwino konse chifukwa mafuta ndi gwero losasinthika komanso kupanga ulusi wopangira kumaipitsanso madzi ndi mpweya.
Ulusi wa semi-synthetic amapangidwa kuchokera ku ulusi wa cellulose wopangidwanso.Ulusi wa cellulose nthawi zambiri umachokera ku mitundu yosiyanasiyana ya nkhuni, ndipo panthawi ya chithandizo, iwo adzaipitsidwa ndi mankhwala opweteka, madzi oipitsa, mpweya, nthaka ndi ogwira ntchito opweteka.
Jiayialso amaperekaulusi wa khofindi ulusi wina wa nayiloni wogwira ntchito.Monga wopanga ulusi wa nayiloni, nthawi zonse timatenga malo oyamba pakupanga chitetezo cha chilengedwe.Takulandilani kudzayendera fakitale yathu ndikusankha ulusi wathu wapamwamba momwe mumafunira.
