Tanthauzo la nsalu zoteteza chilengedwendi yotakata kwambiri, zomwe zimachitikanso chifukwa cha tanthauzo lalikulu la nsalu. Kawirikawiri, nsalu zosamalira chilengedwe zimatha kuonedwa ngati zopanda mpweya wambiri, zosunga mphamvu, zopanda zinthu zovulaza mwachilengedwe, zosamalira chilengedwe komanso zobwezerezedwanso.
Nsalu zosawononga chilengedweZingagawidwe m'magulu awiri: nsalu zoteteza chilengedwe tsiku ndi tsiku ndi nsalu zoteteza chilengedwe m'mafakitale.
Nsalu zoteteza chilengedwe zopangidwa ndi mafakitale zimapangidwa ndi zinthu zopanda chitsulo komanso zitsulo monga PVC, ulusi wa polyester, ulusi wagalasi, ndi zina zotero, zomwe zingathandize kuteteza chilengedwe, kusunga mphamvu ndi kubwezeretsanso zinthu pogwiritsa ntchito zenizeni.
Mitundu yanji yansalu zabwino pa moyo Kodi alipo?
1. nsalu ya poliyesitala yobwezerezedwanso
Nsalu ya RPET ndi mtundu watsopano wa nsalu yobwezeretsedwanso komanso yosamalira chilengedwe. Dzina lake lonse ndi Recycled PET Fabric (nsalu ya polyester yobwezeretsedwanso). Zinthu zake zopangira ndi ulusi wa RPET wopangidwa kuchokera ku mabotolo a PET obwezeretsedwanso kudzera mu kuyang'anira bwino kusiyanitsa-kudula-kujambula, kuziziritsa ndi kusonkhanitsa. Yodziwika bwino kuti nsalu yoteteza chilengedwe ya mabotolo a Coke. Nsaluyi ikhoza kubwezeretsedwanso ndikugwiritsidwanso ntchito, zomwe zingasunge mphamvu, kugwiritsa ntchito mafuta ndikuchepetsa mpweya wa carbon dioxide. Paundi iliyonse ya nsalu ya RPET yobwezeretsedwanso imatha kusunga mphamvu ya 61,000 BTU, yomwe ndi yofanana ndi mapaundi 21 a carbon dioxide. Pambuyo popaka utoto wa chilengedwe, kuphimba chilengedwe ndi kalendala, nsaluyi imathanso kuzindikira MTL, SGS, ITS ndi miyezo ina yapadziko lonse lapansi, kuphatikiza phthalates (6P), formaldehyde, lead (Pb), polycyclic aromatic hydrocarbons, Nonkifen ndi zizindikiro zina zoteteza chilengedwe zafika pamiyezo yaposachedwa kwambiri yoteteza chilengedwe ku Europe komanso miyezo yaposachedwa kwambiri yoteteza chilengedwe ku America.
Thonje lachilengedwe limapangidwa mu ulimi pogwiritsa ntchito feteleza wachilengedwe, kulamulira tizilombo ndi matenda mwachilengedwe, komanso kusamalira ulimi mwachilengedwe. Mankhwala ophera tizilombo saloledwa. Kuyambira mbewu mpaka zinthu zaulimi, zonse ndi zachilengedwe ndipo sizikuipitsidwa. Ndipo ndi "Safety and Quality Standards for Agricultural Products" yolengezedwa ndi mayiko osiyanasiyana kapena WTO/FAO ngati muyeso, kuchuluka kwa zinthu zoopsa komanso zoopsa monga mankhwala ophera tizilombo, zitsulo zolemera, nitrates, tizilombo toopsa (kuphatikizapo tizilombo toyambitsa matenda, mazira a tizilombo toyambitsa matenda, ndi zina zotero) mu thonje kumayendetsedwa mkati mwa malire omwe atchulidwa mu muyezo womwe uli mkati, komanso thonje lovomerezeka la zinthu.
3. thonje la mtundu
Thonje la mtundu ndi mtundu watsopano wa thonje momwe ulusi wa thonje uli ndi mitundu yachilengedwe. Thonje la mtundu wachilengedwe ndi mtundu watsopano wa nsalu zomwe zimalimidwa ndi ukadaulo wamakono wa bioengineering, ndipo ulusiwo umakhala ndi mtundu wachilengedwe thonje likatsegulidwa. Poyerekeza ndi thonje wamba, ndi lofewa, lopumira, lotanuka, komanso lomasuka kuvala, kotero limatchedwanso kuti A level yapamwamba ya thonje lachilengedwe. Padziko lonse lapansi limadziwika kuti zero pollution (Zeropollution). Chifukwa thonje lachilengedwe liyenera kusunga mawonekedwe ake achilengedwe panthawi yobzala ndi kuluka, utoto womwe ulipo wopangidwa ndi mankhwala sungathe kuupaka utoto. Kupaka utoto wachilengedwe kokha ndi utoto wachilengedwe wa masamba onse. Thonje lachilengedwe lopakidwa utoto wachilengedwe lili ndi mitundu yambiri ndipo lingakwaniritse zosowa zambiri. Akatswiri amaneneratu kuti bulauni ndi wobiriwira zidzakhala mitundu yotchuka ya zovala kumayambiriro kwa zaka za m'ma 2000. Limayimira zachilengedwe, chilengedwe, zosangalatsa, mafashoni. Kuphatikiza pa zovala za thonje la bulauni ndi wobiriwira, mitundu ya zovala zabuluu, zofiirira, zofiira, zofiirira ndi zina zikupangidwa pang'onopang'ono.
4. ulusi wa nsungwi
Ulusi wa nsungwi ndi nsungwi, ndipo ulusi wofunikira wopangidwa ndi ulusi wa nsungwi ndi wobiriwira. Nsalu yolukidwa ndi zovala zopangidwa ndi ulusi wa thonje wopangidwa ndi zinthuzi zimakhala ndi mawonekedwe osiyana ndi ulusi wa cellulose wamtundu wa thonje ndi matabwa. Kalembedwe kake kapadera: kukana kukalamba, kusapakidwa, kuyamwa chinyezi kwambiri komanso kuumitsa mwachangu, kulola mpweya kulowa bwino, kupendekera bwino, kusalala komanso kokhuthala, kofewa ngati silika, bowa, njenjete ndi mabakiteriya, kozizira komanso komasuka kuvala, ndipo kumakhala ndi kukongola komanso kusamalira khungu. Kupaka utoto kwabwino kwambiri, kuwala kowala, mphamvu yabwino yachilengedwe yolimbana ndi mabakiteriya komanso kuteteza chilengedwe, kutsatira zomwe anthu amakono akuchita kuti akhale ndi thanzi labwino komanso chitonthozo.
Zachidziwikire, nsalu za ulusi wa nsungwi zilinso ndi zovuta zina. Nsalu iyi ya chomera ndi yofooka kuposa nsalu zina wamba, imakhala ndi chiwopsezo chachikulu cha kuwonongeka, ndipo chiwopsezo cha kuchepa kwake n'chovuta kuwongolera. Pofuna kuthana ndi zolakwika izi, ulusi wa nsungwi nthawi zambiri umasakanizidwa ndi ulusi wamba. Kusakaniza ulusi wa nsungwi ndi mitundu ina ya ulusi mu chiŵerengero china sikungowonetsa kokha mawonekedwe a ulusi wina komanso kumapereka mawonekedwe a ulusi wa nsungwi, zomwe zimapangitsa kuti nsalu zolukidwa zikhale zatsopano. Ulusi woyera wopota ndi wosakanikirana (wosakanikirana ndi Tencel, Modal, polyester yothira thukuta, polyester ya oxygen ion, ulusi wa chimanga, thonje, acrylic ndi ulusi wina mosiyanasiyana) ndi nsalu zomwe zimakondedwa kwambiri poluka nsalu zoyandikana. Mwanjira yamakono, zovala za masika ndi chilimwe zopangidwa ndi nsalu za ulusi wa nsungwi zimakhala zogwira mtima kwambiri.
