Ulusi wobwezerezedwanso ndi wopangidwanso

Chifukwa cha kuchepa kwa chuma padziko lonse lapansi, kuwonongeka kwa mpweya wowonjezera kutentha kwa chilengedwe ndi zovuta zina pa moyo wa anthu, kuzindikira kwa anthu za moyo wobiriwira kukukulirakulira.M'zaka zaposachedwa mawu oti "zatsopano / zosinthidwanso" ayamba kutchuka mumakampani opanga zovala ndi nsalu zapakhomo.Ena odziwika padziko lonse lapansi ovala zopangidwa monga Adidas, Nike, Uniqlo ndi makampani ena ndi omwe amalimbikitsa gululi.

Kodi ulusi wopangidwanso ndi cellulose ndi ulusi wopangidwanso ndi polyester ndi chiyani?Anthu ambiri amasokonezeka ndi izi.

1. Kodi ulusi wopangidwanso ndi cellulose ndi chiyani?

Zopangira za ulusi wopangidwanso ndi cellulose wachilengedwe (mwachitsanzo thonje, hemp, nsungwi, mitengo, zitsamba).Kuti apange magwiridwe antchito abwino a ulusi wopangidwanso wa cellulose timangofunika kusintha mawonekedwe a cellulose achilengedwe.Kapangidwe kake kamankhwala kamakhala kosasinthika.Kuti tifotokoze mophweka, ulusi wopangidwanso wa cellulose umachotsedwa ndikuzunguliridwa kuchokera kuzinthu zoyambira zachilengedwe kudzera muukadaulo wopanga.Ndi ya ulusi wopangira, koma ndi wachilengedwe komanso wosiyana ndi ulusi wa polyester.SALI m'gulu la ulusi wamankhwala!

Ulusi wa Tencel, womwe umadziwikanso kuti "Lyocell", ndiwofala kwambiri pamsika.Sakanizani nkhuni za mtengo wa coniferous, madzi ndi zosungunulira ndi kutentha mpaka kusungunuka kwathunthu.Pambuyo pochotsa chidetso ndikupota ntchito yopanga zinthu za "Lyocell" yatha.Mfundo yoluka ya Modal ndi Tencel ndiyofanana.Zida zake zopangira zimachokera kumitengo yoyambirira.Ulusi wa bamboo umagawidwa kukhala nsungwi zamkati ulusi ndi choyambirira nsungwi ulusi.Ulusi wa Bamboo pulp umapangidwa powonjezera zowonjezera pazake za nsungwi za Moso ndikukonzedwa ndi kupota konyowa.Pomwe nsungwi zoyambirira zimachotsedwa ku nsungwi ya Moso pambuyo pa chithandizo chachilengedwe chachilengedwe.

2, Kodi zosinthidwanso / zobwezerezedwanso poliyesitala CHIKWANGWANI?

Malinga ndi mfundo yosinthika njira zopangira ulusi wopangidwanso wa polyester zitha kugawidwa m'magulu awiri: thupi ndi mankhwala.Njira yakuthupi imatanthawuza kusanja, kuyeretsa ndi kuyanika zinyalala za polyester ndikusungunula mozungulira molunjika.Pamene mankhwala njira amatanthauza depolymerizing zinyalala poliyesitala zipangizo polymerization monoma kapena polymerization intermediates mwa zimachitikira mankhwala;kusinthika polymerization pambuyo kuyeretsedwa ndi kupatukana masitepe ndiyeno kusungunula kupota.

Chifukwa chaukadaulo wosavuta wopanga, njira yosavuta komanso mtengo wotsika wopanga njira yakuthupi, ndiyo njira yayikulu yobwezeretsanso poliyesitala m'zaka zaposachedwa.Zoposa 70% mpaka 80% za mphamvu yopangira polyester yobwezerezedwanso imapangidwanso ndi njira yakuthupi.Ulusi wake umapangidwa kuchokera ku mabotolo amadzi amchere amchere ndi mabotolo a Coke.Ndilo lotchuka kwambiri m’mayiko otukuka monga ku Ulaya ndi ku United States chifukwa limagwiritsidwanso ntchito m’zinyalala.Polyester yobwezerezedwanso imatha kuchepetsa kugwiritsa ntchito mafuta, tani iliyonse ya ulusi wa PET womalizidwa imatha kupulumutsa matani 6 amafuta.Ikhoza kuthandizira kuchepetsa kuipitsidwa kwa mpweya ndikuwongolera kutentha kwa mpweya.Mwachitsanzo: kukonzanso botolo lapulasitiki lokhala ndi voliyumu ya 600cc = kuchepetsa mpweya wa 25.2g = kupulumutsa mafuta kwa 0.52cc = kupulumutsa madzi kwa 88.6cc.

Chifukwa chake zida zopangidwanso / zobwezerezedwanso zidzakhala zida zotsatiridwa ndi anthu mtsogolo.Zinthu zambiri zokhudzana ndi moyo wathu monga zovala, nsapato ndi matebulo amapangidwa ndi zinthu zobwezerezedwanso ndi chilengedwe.Idzalandiridwa kwambiri ndi anthu.
