M'zaka zaposachedwa, ulusi wopangidwanso wa cellulose (monga viscose, modal, Tencel ndi ulusi wina) wakhala ukutuluka mosalekeza, zomwe sizimangokwaniritsa zosowa za anthu munthawi yake, komanso kuchepetsa pang'ono mavuto akusowa kwazinthu komanso kuwonongeka kwa chilengedwe.
Chifukwa ulusi wopangidwanso wa cellulose uli ndi ubwino wa ulusi wa cellulose wachilengedwe komanso ulusi wopangira, umagwiritsidwa ntchito kwambiri munsalu zomwe zimagwiritsidwa ntchito kwambiri kuposa kale.
01.Wamba viscose CHIKWANGWANI
Viscose fiber ndi dzina lonse la viscose fiber. Ndi fiber ya cellulose yomwe imapezeka pochotsa ndikukonzanso mamolekyu a fiber kuchokera ku cellulose yamatabwa achilengedwe okhala ndi "matabwa" ngati zopangira.
Njira yokonzekera: cellulose ya chomera imasinthidwa kukhala alkali cellulose, kenako imakhudzidwa ndi carbon disulfide kupanga cellulose xanthate. Yankho la viscous lomwe limapezeka posungunula mumadzi amchere limatchedwa viscose. Viscose amapangidwa mu viscose CHIKWANGWANI pambuyo chonyowa kupota ndi mndandanda wa ndondomeko processing
The sanali yunifolomu wa zovuta akamaumba ndondomeko wamba viscose CHIKWANGWANI adzapanga mtanda chigawo cha ochiritsira viscose CHIKWANGWANI kuoneka m'chiuno mozungulira kapena osasamba, ndi mabowo mkati ndi osasamba grooves mu malangizo kotenga nthawi. Viscose imakhala ndi mayamwidwe abwino kwambiri a chinyezi komanso utoto, koma modulus ndi mphamvu zake ndizochepa, makamaka mphamvu yake yonyowa ndiyotsika.
02.Modal fiber
Ulusi wa Modal ndi dzina lamalonda la ulusi wonyowa kwambiri wa modulus viscose. Kusiyanitsa pakati pa ulusi wa modal ndi wamba wa viscose ulusi ndikuti ulusi wa modal umapangitsa kuti pakhale zovuta zamphamvu zotsika komanso zotsika modulus wamba wamba wa viscose ulusi wonyowa, komanso amakhala ndi mphamvu yayikulu komanso modulus m'malo onyowa, motero nthawi zambiri amatchedwa mkulu wonyowa modulus viscose. fiber.
Zogulitsa zofananira za opanga ulusi wosiyanasiyana zilinso ndi mayina osiyanasiyana, monga Lenzing modal TM brand fiber, polynosic fiber, Fuqiang fiber, hukapok ndi newal brand name of lanzing company ku Austria.
Njira yokonzekera: Modulus yonyowa kwambiri imapezedwa ndi njira yapadera yopangira. Zosiyana ndi njira yopangira fiber viscose:
(1) Ma cellulose ayenera kukhala ndi digiri yapamwamba ya polymerization (pafupifupi 450).
(2) Njira yokonzekera yozungulira yozungulira imakhala ndi ndende yayikulu.
(3) The zikuchokera yoyenera coagulation kusamba (monga kuonjezera zili zinki sulfate mmenemo) zakonzedwa, ndi kutentha kwa coagulation kusamba yafupika kuchedwa kupanga liwiro, amene amathandiza kupeza ulusi ndi dongosolo yaying'ono ndi mkulu crystallinity. . Mapangidwe amkati ndi akunja a ulusi omwe amapezeka motere ndi ofanana. Mapangidwe apakati pakhungu pagawo la ulusi sawoneka bwino ngati ulusi wamba wa viscose. Mawonekedwe apakati amakhala ozungulira kapena ozungulira m'chiuno, ndipo kutalika kwautali kumakhala kosalala. Ulusiwu uli ndi mphamvu zambiri komanso modulus mumalo onyowa, ndipo zinthu zabwino kwambiri za hygroscopic ndizoyeneranso zovala zamkati.
Mapangidwe a zigawo zamkati ndi zakunja za ulusi ndizofanana. Mapangidwe a khungu lapakati pakhungu la ulusi wodutsa magawo sakuwonekeratu kuposa ulusi wamba wa viscose. Mawonekedwe apakati amakhala ozungulira kapena ozungulira m'chiuno, ndipo utali wozungulira umakhala wosalala. Ili ndi mphamvu zambiri komanso modulus m'malo onyowa komanso magwiridwe antchito abwino kwambiri amayamwidwe.
03.Lessel CHIKWANGWANI
Ulusi wa Lyocell ndi mtundu wa ulusi wa cellulose wopangidwa ndi polima wachilengedwe. Anapangidwa ndi kampani ya British kautor ndipo kenako anasamutsidwa ku kampani ya Swiss Lanjing. Dzina lamalonda ndi Tencel, ndipo dzina lake "Tiansi" limatengedwa ku China.
Kukonzekera njira: Lyocell ndi mtundu watsopano wa mapadi CHIKWANGWANI wokonzedwa mwachindunji Kusungunuka mapadi zamkati mu kupota njira ndi n-methylmoline okusayidi (NMMO) amadzimadzi njira monga zosungunulira, ndiye ntchito chonyowa kupota kapena youma chonyowa kupota njira, ntchito ndende inayake ya nmmo-h2o njira ngati coagulation kusamba kupanga CHIKWANGWANI, ndiyeno kutambasula, kutsuka, opaka mafuta ndi kuyanika spun pulayimale CHIKWANGWANI.
Poyerekeza ndi ochiritsira viscose CHIKWANGWANI kupanga njira, mwayi waukulu wa kupota njira imeneyi n'chakuti NMMO akhoza mwachindunji kupasuka mapadi zamkati, kupanga ndondomeko kupota katundu akhoza kwambiri chosavuta, ndi kuchira mlingo wa NMMO angafikire oposa 99%, ndi kupanga sikuyipitsa konse chilengedwe.
Kapangidwe ka morphological wa Lyocell ulusi ndi wosiyana kotheratu ndi viscose wamba. Mapangidwe apakati ndi ofanana, ozungulira, ndipo palibe khungu lapakati pa khungu. The longitudinal pamwamba ndi yosalala ndipo palibe poyambira. Imakhala ndi zida zamakina apamwamba kuposa ulusi wa viscose, kukhazikika kwabwino kwachabechabe (kutsika ndi 2%) komanso kuyamwa kwakukulu kwa chinyezi. Ili ndi kuwala kokongola, chogwirira chofewa, chokoka bwino komanso kukongola kwabwino.
Kusiyana pakati pa viscose, modal ndi lessel
(1)Chigawo cha Fiber
(2)Makhalidwe a CHIKWANGWANI
•Viscose fiber
• Imakhala ndi mayamwidwe abwino ndipo imakwaniritsa zofunikira za thupi la munthu. Nsaluyo ndi yofewa, yosalala, yopumira, yosakhala ndi magetsi osasunthika, osamva UV, omasuka kuvala, osavuta kupaka utoto, utoto wowala pambuyo popaka utoto, kuthamanga kwamtundu wabwino, komanso kupindika bwino. Modulus yonyowa ndi yotsika, kuchuluka kwa shrinkage ndikwambiri ndipo ndikosavuta kupunduka. Dzanja limakhala lolimba pambuyo poyambitsa, ndipo kusungunuka ndi kukana kuvala kumakhala kovutirapo.
• Ulusi wa Modal
• Ili ndi kukhudza kofewa, kowala ndi koyera, mtundu wowala komanso kufulumira kwamtundu wabwino. Nsaluyo imakhala yosalala kwambiri, pamwamba pa nsaluyo ndi yowala komanso yonyezimira, ndipo kukongola kwake kuli bwino kuposa ulusi wa thonje, poliyesitala ndi viscose. Lili ndi mphamvu ndi kulimba kwa ulusi wopangidwa, ndipo limakhala ndi kuwala ndi kumva kwa silika. Nsaluyo imakhala ndi kukana makwinya komanso kukana kusita, kuyamwa bwino kwamadzi komanso kutulutsa mpweya, koma nsaluyo ndi yosauka.
• Chingwe chochepa
• Ili ndi zinthu zambiri zabwino kwambiri za ulusi wachilengedwe ndi ulusi wopangidwa, kuwala kwachilengedwe, kumva kosalala, mphamvu yayikulu, kwenikweni palibe kutsika, kutsekemera kwabwino kwa chinyezi ndi permeability, zofewa, zofewa, zosalala komanso zoziziritsa kukhosi, zowoneka bwino, zokhazikika komanso zolimba.
(3)Kuchuluka kwa ntchito
• Viscose fiber
•Zingwe zazifupi zimatha kukhala zopota kapena kusakanikirana ndi ulusi wina wansalu, womwe ndi woyenera kupanga zovala zamkati, zovala zakunja ndi zokongoletsa zosiyanasiyana. Nsalu ya filament ndi yopepuka komanso yopyapyala, ndipo imatha kugwiritsidwa ntchito ngati quilt ndi nsalu zokongoletsera kuwonjezera pa zovala.
•Modal fiber
•Nsalu zoluka za Modale zimagwiritsidwa ntchito makamaka popanga zovala zamkati, komanso zamasewera, kuvala wamba, malaya, nsalu zopangidwa mwaluso, ndi zina zambiri. Kuphatikizana ndi ulusi wina kungapangitse kusawongoka kosauka kwa zinthu zoyera za modal.
•Lessel fiber
• Imakhudza mbali zonse za nsalu, kaya ndi thonje, ubweya, silika, hemp, kuluka kapena kuluka, imatha kupanga zinthu zapamwamba komanso zapamwamba.
