1.Kuhlukaniswa ngobuchwepheshe bokucubungula
I-fiber evuselelwe yenziwa ngemicu yemvelo (ama-linter kakotini, ukhuni, uqalo, i-hemp, i-bagasse, umhlanga, njll.) ngokusebenzisa inqubo ethile yamakhemikhali nokuphotha ukuze kulungiswe kabusha ama-molecule e-cellulose, awaziwa nangokuthi imicu eyenziwe umuntu. Ngenxa yokuthi ukwakheka kwamakhemikhali kanye nesakhiwo samakhemikhali kuhlala kungashintshile ngesikhathi sokucutshungulwa, ukukhiqizwa nokuphothwa kwezinto zemvelo, kubizwa nangokuthi i-fiber evuselelwe.
Kusukela ezidingweni zenqubo yokucutshungulwa kanye nokuhlehla kokucekelwa phansi kokuvikelwa kwemvelo, ingahlukaniswa ibe ukuvikela okungezona ezemvelo (indlela yokuhlakazeka kukakotini/ukhuni ngokungaqondile) kanye nenqubo yokuvikela indawo ezungezile (indlela yokuhlakazwa kukakotini/ukhuni ngokuqondile). Inqubo yokuvikela okungezona ezemvelo (njenge-viscose yendabuko iRayon) iwukuba i-sulfonate ukotini/ukhuni olufakwe nge-alkali nge-carbon disulfide ne-alkali cellulose ukwenza isixazululo sesitoko esiphothayo, bese ekugcineni sisebenzise ukuphotha okumanzi ukuze kuvuselelwe Yenziwe nge-cellulose. i-coagulation.
Ubuchwepheshe bokuvikela imvelo (obufana ne-lyocell) busebenzisa isixazululo samanzi se-N-methylmorpholine (NMMO) njengesixazululi ukuze kuncibilike ngokuqondile i-cellulose pulp esixazululweni sokuphotha, bese sisebenzisa ukuphotha okumanzi noma ukuphotha okumanzi okomile okwenziwe. Uma kuqhathaniswa nendlela yokukhiqiza ye-viscose fiber evamile, inzuzo enkulu ukuthi i-NMMO ingahlakaza ngokuqondile u-cellulose pulp, inqubo yokukhiqiza i-dope yokuphotha ingenziwa ibe lula kakhulu, izinga lokubuyisela isisombululo lingafinyelela ngaphezu kwama-99%, futhi inqubo yokukhiqiza ayingcolisi neze. imvelo. Izinqubo zokukhiqiza ze-Tencel®, i-Richel®, i-Gracell®, i-Yingcell®, i-bamboo fiber, ne-Macelle zonke ziyizinqubo ezihambisana nemvelo.
2.Ukuhlukaniswa ngezici zomzimba eziyinhloko
Izinkomba ezibalulekile ezifana ne-modulus, amandla, kanye ne-crystallinity (ikakhulukazi ngaphansi kwezimo ezimanzi) yizici ezibalulekile ezithinta ukushelela kwendwangu, ukufinyeleleka komswakama, nokudonsa. Isibonelo, i-viscose evamile ine-hygroscopicity enhle kakhulu kanye nempahla yokudaya kalula, kodwa i-modulus namandla ayo aphansi, ikakhulukazi amandla amanzi aphansi. I-Modal fiber ithuthukisa ukushiyeka okukhulunywe ngakho ngenhla kwe-viscose fiber, futhi inamandla aphezulu kanye ne-modulus esimweni esimanzi, ngakho-ke ngokuvamile ibizwa ngokuthi i-high wet modulus viscose fiber. Ukwakheka kwe-Modal kanye nezinga le-polymerization ye-cellulose ku-molecule kuphakeme kunaleyo ye-viscose fiber evamile futhi iphansi kune-Lyocell. Indwangu ibushelelezi, ingaphezulu lendwangu liyakhanya futhi liyacwebezela, futhi ukudonseka kungcono kunokotini okhona, i-polyester, ne-rayon. Inokukhanya okufana nosilika nokuzwakala, futhi iyindwangu yemvelo eyenziwe nge-mercerized.
3.Imithetho Yamagama Ohwebo Yemicu Evuselelwe
Imikhiqizo ye-cellulose eluhlaza futhi evumelana nemvelo evuselelwe kabusha ye-cellulose eyenziwe ezweni lami ilandela imithetho ethile ngokwamagama empahla. Ukuze kube lula ukuhwebelana kwamazwe ngamazwe, ngokuvamile banamagama wesiShayina (noma i-pinyin yesiShayina) namagama esiNgisi. Kunezigaba ezimbili eziyinhloko zamagama amasha omkhiqizo we-viscose fiber:
Enye i-Modal (Modal). Kungase kube ukuqondana nje ukuthi igama lesiNgisi elithi "Mo" linendlela efanayo yokubiza "ukhuni" lwesiShayina, ngakho abathengisi basebenzisa lokhu ukuze bakhangise i-"Modal" ukuze bagcizelele ukuthi i-fiber isebenzisa izinkuni zemvelo njengento eluhlaza, empeleni "Modal" . Amazwe angaphandle ikakhulukazi asebenzisa i-pulp yokhuni yekhwalithi ephezulu, futhi elithi "Dyer" liwukuhunyushwa kwezinhlamvu ezingemuva kolimi lwesiNgisi. Ngokusekelwe kulokhu, noma iyiphi i-fiber ene- "Dyer" emikhiqizweni yezinkampani zokwenziwa ze-fiber zokwenziwa zezwe lethu ingeyalolu hlobo lomkhiqizo, olubizwa nge-China Modal. : Okufana ne-Newdal (i-Newdal viscose fiber enamandla), i-Sadal (Sadal), i-Bamboodale, i-Thincell, njll.
Okwesibili, izinkulumo zikaLyocell (Leocell) kanye neTencel® (Tencel) zinembe kakhulu. Igama lesiShayina le-Lyocell (lyocell) fiber ebhaliswe ezweni lami yinkampani yaseBrithani i-Acordis ithi "Tencel®". Ngo-1989, igama le-Lyocell (Lyocell) fiber laqanjwa yi-BISFA (I-International Man-made Fiber and Synthetic Fiber Standards Bureau), futhi i-cellulose fiber evuselelwe yaqanjwa ngokuthi i-Lyocell. Igama elithi "Lyo" livela egameni lesiGreki elithi "Lyein", elisho ukuncibilika, ""iseli" lithathwe ku-cellulose "Cellulose", kokubili ndawonye "Lyocell", kanye ne-homonym yesiShayina ibizwa ngokuthi i-Lyocell. Abezinye izizwe banokuqonda okuhle yesiko lamaShayina lapho ukhetha igama lomkhiqizo, igama lomkhiqizo walo yi-Tencel® noma "Tencel®".
