1.Classified los ntawm kev siv tshuab
Regenerated fibers yog tsim los ntawm ntuj fibers (paj rwb linters, ntoo, xyoob, hemp, bagasse, reed, thiab lwm yam) los ntawm ib tug tej yam txheej txheem tshuaj thiab spinning rau reshape lub cellulose molecules, kuj hu ua man-made fibers. Vim hais tias cov tshuaj muaj pes tsawg leeg thiab cov qauv tshuaj tseem tsis hloov thaum lub sij hawm ua, tsim thiab spinning ntawm cov ntaub ntawv ntuj, nws tseem hu ua regenerated fiber.
Los ntawm qhov yuav tsum tau ua ntawm cov txheej txheem ua thiab regression degradation ib puag ncig kev tiv thaiv qauv, nws tuaj yeem muab faib ua kev tiv thaiv ib puag ncig (cotton / wood pulp indirect dissolution method) thiab txheej txheem tiv thaiv ib puag ncig (paj rwb / ntoo pulp ncaj qha dissolution method). Cov txheej txheem kev tiv thaiv tsis yog ib puag ncig (xws li cov tsoos viscose Rayon) yog sulfonate cov alkali-kho paj rwb / ntoo pulp nrog carbon disulfide thiab alkali cellulose los ua cov tshuaj spinning stock, thiab thaum kawg siv ntub spinning rau regenerate Nws yog ua los ntawm cellulose. coagulation.
Kev tiv thaiv ib puag ncig technology (xws li lyocell) siv N-methylmorpholine oxide (NMMO) aqueous tov raws li cov kuab tshuaj mus ncaj qha yaj cellulose pulp rau hauv cov tshuaj spinning, thiab ces ua nws los ntawm ntub spinning los yog qhuav-ntub spinning ua. Piv nrog rau txoj kev tsim khoom ntawm cov viscose fiber ntau, qhov zoo tshaj plaws yog tias NMMO tuaj yeem ncaj qha yaj cellulose pulp, cov txheej txheem ntawm spinning dope tuaj yeem ua kom yooj yim heev, cov tshuaj rov qab tuaj yeem ncav cuag ntau dua 99%, thiab cov txheej txheem tsim khoom tsis tshua muaj kuab paug. ib puag ncig. Cov txheej txheem ntau lawm ntawm Tencel®, Richel®, Gracell®, Yingcell®, xyoob fiber ntau, thiab Macelle yog tag nrho cov txheej txheem ib puag ncig.
2.Classification los ntawm cov yam ntxwv tseem ceeb ntawm lub cev
Cov cim tseem ceeb xws li modulus, lub zog, thiab crystallinity (tshwj xeeb yog nyob rau hauv cov dej ntub dej) yog qhov tseem ceeb uas cuam tshuam rau cov ntaub slipperiness, noo noo permeability, thiab drape. Piv txwv li, viscose zoo tib yam muaj hygroscopicity zoo heev thiab yooj yim dyeing cuab yeej, tab sis nws cov modulus thiab lub zog yog tsawg, tshwj xeeb tshaj yog lub zog ntub dej yog tsawg. Modal fiber txhim kho qhov tsis zoo ntawm cov lus hais saum toj no ntawm viscose fiber ntau, thiab tseem muaj lub zog siab thiab modulus hauv lub xeev ntub, yog li nws feem ntau hu ua siab ntub modulus viscose fiber. Cov qauv ntawm Modal thiab cov degree ntawm polymerization ntawm cellulose nyob rau hauv lub molecule yog siab tshaj li ntawm cov viscose fiber zoo tib yam thiab qis dua li ntawm Lyocell. Cov ntaub yog du, qhov saum npoo ntawm cov ntaub yog ci thiab ci, thiab cov drapability zoo dua li cov paj rwb uas twb muaj lawm, polyester, thiab rayon. Nws muaj cov ntaub zoo li silk thiab zoo li, thiab yog cov ntaub mercerized ntuj.
3.Rules of Trade Names for Regenerated Fibers
Cov ntsuab thiab ib puag ncig tus phooj ywg high-humidity modulus regenerated cellulose khoom tsim nyob rau hauv kuv lub teb chaws ua raws li tej kev cai nyob rau hauv cov nqe lus ntawm cov khoom npe. Txhawm rau pab txhawb kev lag luam thoob ntiaj teb, lawv feem ntau muaj cov npe Suav (lossis Suav pinyin) thiab cov npe Askiv. Muaj ob pawg tseem ceeb ntawm cov khoom tshiab ntsuab viscose fiber ntau lub npe:
Ib qho yog Modal (Modal). Tej zaum nws yuav yog ib qho xwm txheej uas cov lus Askiv "Mo" muaj tib lub suab zoo li Suav "ntoo", yog li cov tub lag luam siv qhov no los tshaj tawm "Modal" los qhia tias cov fiber ntau siv ntoo ua raw khoom, uas yog "Modal" tiag tiag. . Cov teb chaws txawv teb chaws feem ntau siv cov ntoo ntoo zoo nkauj, thiab "Dyer" yog kev txhais cov ntawv tom qab lus Askiv. Raws li qhov no, ib qho fiber ntau nrog "Dyer" nyob rau hauv cov khoom ntawm peb lub teb chaws cov hluavtaws fiber ntau raug tuam txhab uas muag belongs rau hom khoom, uas yog hu ua Tuam Tshoj Modal. : Xws li Newdal (Newdal muaj zog viscose fiber), Sadal (Sadal), Bamboodale, Thincell, thiab lwm yam.
Qhov thib ob, cov lus qhia ntawm Lyocell (Leocell) thiab Tencel® (Tencel) yog qhov tseeb dua. Suav lub npe ntawm Lyocell (lyocell) fiber ntau sau npe hauv kuv lub tebchaws los ntawm lub tuam txhab British Acordis yog "Tencel®". Xyoo 1989, lub npe ntawm Lyocell (Lyocell) fiber ntau tau raug npe los ntawm BISFA (International Man-made Fiber and Synthetic Fiber Standards Bureau), thiab cov cellulose fiber ntau tau muab npe hu ua Lyocell. "Lyo" los ntawm Greek lo lus "Lyein", uas txhais tau tias yaj, ""cell" yog muab los ntawm cellulose "Cellulose", ob leeg ua ke yog "Lyocell", thiab Suav homonym hu ua Lyocell. Cov neeg txawv teb chaws muaj kev nkag siab zoo. ntawm Suav kab lis kev cai thaum xaiv cov khoom npe Lyocell, nws cov khoom npe yog Tencel® lossis "Tencel®".
