Modal ndi rayon onse ndi ulusi wobwezerezedwanso, koma zopangira za Modal ndi zamkati zamatabwa, pomwe zopangira za rayon ndi ulusi wachilengedwe.Kumbali ina yake, ulusi uŵiriwu ndi ulusi wobiriwira.Ponena za kumverera kwa manja ndi kalembedwe, ndizofanana kwambiri, koma mitengo yawo ili kutali.
Modali
Modal fiber ndi nsalu yopangidwa kumene m'zaka zaposachedwa, yomwe imatchedwa Modal mwachidule.Ndi ulusi wamakono womwe umaphatikiza mawonekedwe apamwamba a ulusi wachilengedwe ndi magwiridwe antchito a ulusi wopangira.Ili ndi kufewa kwa thonje, kunyezimira kwa silika, ndi kusalala kwa hemp.Komanso, kuyamwa kwake m'madzi ndi mpweya wake ndikwabwino kuposa thonje, ndipo imakhala ndi utoto wambiri.Mtundu wa nsalu ndi wowala komanso wodzaza.Ulusi wa Modal ukhoza kusakanikirana ndikuphatikizana ndi mitundu yosiyanasiyana ya ulusi, monga thonje, hemp, silika, ndi zina zotero, kuti nsaluzi zikhale zabwino kwambiri, kuti nsaluyo ikhale yofewa komanso yosalala, perekani kusewera kwa makhalidwe awo. ulusi, ndikukhala bwino kuvala zotsatira.
Rayon
Rayon ndi dzina lodziwika bwino la viscose fiber, lomwe limatchedwa rayon mwachidule.Ulusi wa viscose umachokera ku zinthu zopangidwa ndi cellulose monga nkhuni ndi chomera cha ligusticum α－ Cellulose, kapena ulusi wopangidwa ndi anthu wopangidwa kuchokera ku thonje la thonje, womwe umasinthidwa kukhala njira yozungulira yozungulira kenako yonyowa.Mwachidule, rayon ndi mtundu wa ulusi wopangidwanso.
Kusiyana pakati pa Modal ndi Rayon:
Modal ndi ulusi wopangidwanso ndi cellulose wa high wet modulus viscose fiber wopangidwa ndi Lenzing, Austria.Zopangira za ulusi umenewu ndi nkhuni za beech zochokera ku Ulaya.Amapangidwa koyamba kukhala matabwa, kenako amasinthidwa kukhala ulusi kudzera mu njira yapadera yopota.Zopangira za mankhwalawa ndizinthu zonse zachilengedwe, zomwe zilibe vuto kwa thupi la munthu, zimatha kuwonongeka mwachilengedwe, ndipo sizowopsa kwa chilengedwe.Ulusi wa Modal ndi mtundu wa ulusi wa cellulose, womwe umapangidwa kuchokera ku shrubbery yomwe imapangidwa ku Europe ndipo imapangidwa ndi matabwa slurry kudzera njira yapadera yopota.Ndi ulusi woyera wachilengedwe, womwe uli m'gulu lofanana ndi thonje.
Zogulitsa za Modal zimakhala ndi kufewa kwabwino komanso kuyamwa bwino kwa chinyezi, koma nsalu zawo zimakhala ndi zolimba zosalimba.Tsopano amagwiritsidwa ntchito kwambiri popanga zovala zamkati.Nsalu zoluka za Modal zimagwiritsidwa ntchito makamaka popanga zovala zamkati.Koma Modal ali ndi siliva woyera wonyezimira, utoto wabwino kwambiri komanso utoto wowala pambuyo popaka utoto, womwe ndi wokwanira kuti ugwiritse ntchito ngati malaya.Chifukwa cha izi, Modal yakula kwambiri kukhala malaya ndi nsalu zokongoletsera.Pofuna kukonza kuuma kosawuka kwa zinthu zoyera za Modal, Modal imatha kuphatikizidwa ndi ulusi wina kuti mupeze zotsatira zabwino.JM/C (50/50) akhoza kuthetsa vutoli.Nsalu yosakanikirana yopangidwa ndi ulusi umenewu imapangitsa kuti ulusi wa thonje ukhale wosasinthasintha komanso umapangitsa kuti nsaluyo iwoneke bwino.Modal imathanso kuwonetsa kuluka kwake poluka nsalu zoluka, komanso imatha kulumikizidwa ndi ulusi wina wa ulusi kuluka nsalu zosiyanasiyana.Zogulitsa za Modal zili ndi chiyembekezo chachikulu chakukula kwa zovala zamakono.
Rayon ndi ulusi wa viscose, ulusi wosiyanasiyana wopangidwa ndi anthu.Ma cellulose amchere amapangidwa kuchokera ku cellulose yachilengedwe kudzera mu alkalization, kenako amakumana ndi carbon disulfide kupanga cellulose xanthate.Yankho la viscous lomwe limapezeka poyisungunula mu njira ya alkali yosungunuka imatchedwa viscose.Viscose CHIKWANGWANI amapangidwa pambuyo chonyowa kupota ndi mndandanda wa njira mankhwala.Mfundo zikuchokera kuti mtanda gawo la mapadi (C6H10O5) palibe wamba viscose CHIKWANGWANI ndi zigzag khungu pachimake dongosolo, molunjika mu utali malangizo ndi grooved mu njira yopingasa.Chingwe chokhala ndi fiber coreless chimakhala ndi gawo lozungulira.
Viscose CHIKWANGWANI chimayamwa bwino chinyezi, ndipo chinyezi chimayambanso pafupifupi 13% mumlengalenga.Pambuyo pa kuyamwa kwa chinyezi, chimakula kwambiri, ndipo m'mimba mwake ukuwonjezeka ndi 50%, kotero kuti nsaluyo imakhala yovuta ndipo imakhala ndi chiwerengero chachikulu cha kuchepa pambuyo poyikidwa m'madzi.
Mphamvu yosweka ya ulusi wa viscose wamba ndi wotsika kuposa thonje, pafupifupi 1.6 ~ 2.7 cN/dtex;Elongation panthawi yopuma ndi 16% ~ 22% kuposa thonje;Mphamvu yonyowa imachepa kwambiri, pafupifupi 50% yamphamvu yowuma, ndipo kutalika kwamadzi kumawonjezeka pafupifupi 50%.Modulus yake ndi yocheperapo kuposa ya thonje, ndipo ndiyosavuta kupunduka pansi pa katundu wocheperako, pomwe magwiridwe ake amatsitsimutsidwa ndi osauka, kotero kuti nsaluyo ndi yosavuta kukulitsa komanso imakhala yosakhazikika bwino.Mphamvu ya ulusi wolemera, makamaka mphamvu yonyowa, ndiyokwera kuposa ya viscose wamba, kutalika kwa nthawi yopuma kumakhala kocheperako, ndipo kukhazikika kwa mawonekedwe ndikwabwino.Kukana kwa abrasion kwa viscose wamba kumakhala koyipa, pomwe ulusi wolemera umakhala wabwino.
Kapangidwe kake ka viscose fiber ndi kofanana ndi thonje, motero imakhala yolimbana ndi alkali kuposa asidi, koma kukana kwake kwa alkali ndi asidi ndikoyipa kuposa thonje.Unyinji wolemera uli ndi kukana kwa alkali wabwino komanso kukana kwa asidi.Momwemonso, utoto wa ulusi wa viscose ndi wofanana ndi wa thonje, wokhala ndi chromatography yathunthu yodaya ndi katundu wabwino wodaya.Kuonjezera apo, kutentha kwa viscose fiber ndizofanana ndi thonje, ndi kachulukidwe ka 1.50 ~ 1.52g / cm3 pafupi ndi thonje.
Ulusi wamba wa viscose uli ndi hygroscopicity yabwino, ndi yosavuta kuyika utoto, siyosavuta kupanga magetsi osasunthika, ndipo imakhala ndi kusinthasintha kwabwino.Ulusi waufupi ukhoza kukhala wopota kapena wosakanizidwa ndi ulusi wina wa nsalu.Nsaluyo ndi yofewa, yosalala, yopuma, yomasuka kuvala, mtundu wowala komanso kuthamanga kwamtundu wabwino pambuyo popaka utoto.Ndizoyenera kupanga zovala zamkati, zovala zakunja ndi zolemba zosiyanasiyana zokongoletsera.Nsalu za ulusi ndi zopepuka komanso zoonda, ndipo zimatha kugwiritsidwa ntchito popanga zophimba za quilt ndi nsalu zokongoletsera kuwonjezera pa zovala.Zoyipa zamtundu uwu wa viscose fiber ndi kusathamanga bwino, kunyowa modulus, kutsika kwambiri, kupunduka kosavuta, kusakhazikika bwino komanso kukana kuvala.
Chidule:
Monga onse a rayon ndi Modal ali ndi ulusi wobwezerezedwanso, ma electrostatic reaction transaction amachitika.Serious static magetsi kuphatikiza kukangana kumatulutsa moto wotseguka.M'dzinja ndi m'nyengo yozizira, ma electrostatic reaction transactions ansalu amapangitsanso kugwedezeka kwa nsalu ndi kupukuta.Tsopano amalonda ochulukirachulukira akuwonjezera kumaliza kwa antistatic kumapeto kwa ulusi.Izi sizingangowonjezera kuvala chitonthozo cha nsalu, komanso kuteteza nsalu kuti zisagwedezeke ndi pilling, komanso kusintha maonekedwe ndi kukongola kwa nsalu.Mwachitsanzo, ZJ-Z09H non-ionic antistatic wothandizira amatha kusintha bwino mayamwidwe a chinyezi ndi ma conductivity a nsalu, komanso anti fouling ndi fumbi-umboni katundu, komanso akhoza kusintha odana pilling wa nsalu ndi oposa 0,5 mlingo. .
