Ulusi wopangidwanso umapangidwa ndi ulusi wachilengedwe (zingwe za thonje, matabwa, nsungwi, hemp, bagasse, bango, ndi zina zotero) kudzera munjira inayake yamankhwala ndikuzungulira kuti apangenso mamolekyu a cellulose, omwe amadziwikanso kuti ulusi wopangidwa ndi anthu. Chifukwa kapangidwe ka mankhwala ndi kapangidwe kake kamakhala kosasinthika panthawi yokonza, kupanga ndi kupota zinthu zachilengedwe, amatchedwanso ulusi wopangidwanso.
Kuchokera pazofunikira pakukonza ndikuwonongeka kwachitetezo cha chilengedwe, zitha kugawidwa m'malo osagwirizana ndi chilengedwe (njira yosungunula thonje / nkhuni) ndi njira yotetezera chilengedwe (thonje / nkhuni zamkati molunjika njira). Njira yosateteza zachilengedwe (monga viscose yachikhalidwe Rayon) ndi sulfonate thonje / matabwa opangidwa ndi alkali ndi carbon disulfide ndi alkali cellulose kuti apange njira yozungulira yozungulira, ndipo pamapeto pake amagwiritsa ntchito kupota konyowa kuti apangenso Imapangidwa ndi cellulose. coagulation.
Ukadaulo woteteza zachilengedwe (monga lyocell) umagwiritsa ntchito njira yamadzi ya N-methylmorpholine oxide (NMMO) ngati chosungunulira kuti asungunule mwachindunji zamkati za cellulose mu njira yozungulira, kenako ndikuyipanga ndi kupota konyowa kapena kupota konyowa kopangidwa. Poyerekeza ndi kupanga njira wamba viscose CHIKWANGWANI, mwayi waukulu n'chakuti NMMO akhoza mwachindunji kupasuka mapadi zamkati, kupanga ndondomeko kupota dope akhoza kwambiri chosavuta, njira kuchira mlingo angafikire oposa 99%, ndi kupanga ndondomeko nkomwe kuipitsa. chilengedwe. Kapangidwe ka Tencel®, Richel®, Gracell®, Yingcell®, nsungwi fiber, ndi Macelle zonse ndizogwirizana ndi chilengedwe.
2.Kugawa ndi makhalidwe akuluakulu a thupi
Zizindikiro zazikulu monga modulus, mphamvu, ndi crystallinity (makamaka pansi pa madzi) ndizofunikira zomwe zimakhudza kutsetsereka kwa nsalu, kutsekemera kwa chinyezi, ndi kupukuta. Mwachitsanzo, viscose wamba imakhala ndi hygroscopicity yabwino komanso yosavuta yodaya, koma modulus ndi mphamvu zake ndizochepa, makamaka mphamvu yonyowa ndiyotsika. Ulusi wa Modal umapangitsa kuti zofooka zomwe tatchulazi za viscose fiber, komanso zimakhala ndi mphamvu zambiri komanso modulus m'malo onyowa, motero nthawi zambiri amatchedwa ulusi wonyowa wa modulus viscose. Mapangidwe a Modal ndi kuchuluka kwa polymerization ya cellulose mu molekyulu ndi apamwamba kuposa wamba wamba viscose CHIKWANGWANI ndi otsika kuposa Lyocell. Nsaluyo ndi yosalala, pamwamba pa nsaluyo ndi yowala komanso yonyezimira, ndipo kukongola kwake kuli bwino kuposa thonje, poliyesitala, ndi rayon. Ili ndi kuwala kofanana ndi silika ndikumverera, ndipo ndi nsalu yachilengedwe ya mercerized.
3.Malamulo a Mayina Amalonda a Zingwe Zosinthidwanso
Zobiriwira zobiriwira komanso zachilengedwe zokhala ndi chinyezi chambiri modulus zopangidwanso ndi cellulose zopangidwa m'dziko langa zimatsata malamulo ena okhudzana ndi mayina azinthu. Pofuna kuwongolera malonda apadziko lonse lapansi, nthawi zambiri amakhala ndi mayina achi China (kapena Chinese pinyin) ndi mayina achingerezi. Pali magulu awiri akuluakulu a mayina atsopano a viscose fiber:
Imodzi ndi Modal (Modal). Zingakhale mwangozi kuti "Mo" ya Chingerezi imatchulidwa mofanana ndi "nkhuni" ya ku China, kotero amalonda amagwiritsa ntchito izi kulengeza "Modal" kutsindika kuti ulusi umagwiritsa ntchito nkhuni zachilengedwe monga zopangira, zomwe kwenikweni ndi "Modal" . Mayiko akunja amagwiritsa ntchito matabwa apamwamba kwambiri, ndipo "Dyer" ndikumasulira kwa zilembo kuseri kwa chilankhulo cha Chingerezi. Kutengera izi, ulusi uliwonse wokhala ndi "Dyer" muzogulitsa zamakampani opanga ma fiber opangidwa mdziko lathu ndi wamtunduwu, womwe umatchedwa China Modal. : Monga Newdal (Newdal strong viscose fiber), Sadal (Sadal), Bamboodale, Thincell, etc.
Chachiwiri, mawu a Lyocell (Leocell) ndi Tencel® (Tencel) ndi olondola kwambiri. Dzina lachi China la Lyocell (lyocell) fiber yolembedwa m'dziko langa ndi kampani ya British Acordis ndi "Tencel®". Mu 1989, dzina la Lyocell (Lyocell) fiber linatchedwa BISFA (International Man-made Fiber and Synthetic Fiber Standards Bureau), ndipo ulusi wopangidwanso wa cellulose unatchedwa Lyocell. "Lyo" amachokera ku liwu lachi Greek "Lyein", lomwe limatanthauza kusungunula, ""selo" limachokera ku cellulose "Cellulose", awiriwo pamodzi ndi "Lyocell", ndipo dzina lachi China limatchedwa Lyocell. wa chikhalidwe cha ku China posankha dzina la malonda, dzina lake ndi Tencel® kapena "Tencel®".
