Hauv kev lag luam textile, viscose fiber ntau yog tus txiv neej-ua fiber ntau uas tau nyiam ntau. Nws nyob ib qho chaw ntawm ntau ntau yam nrog nws cov khoom tshwj xeeb. To taub lub ntsiab ntawm viscose fiber ntau yog qhov tseem ceeb tseem ceeb rau kev nkag siab tob ntawm nws cov yam ntxwv thiab kev thov dav.
Lub ntsiab tivthaiv ntawm viscose fiber ntau yog cellulose, lossis ntau dua cellulose tau los ntawm cellulose tshuaj lom neeg thiab kev kho tshuab ua kev siv ntawm lub ntuj cellulose. Nws cov ntaub ntawv raw tsuas yog los ntawm cov nroj tsuag nplua nuj nyob rau hauv xwm, xws li cov kab hlau ntev, muab cov tshuaj txhuam hniav ntau rau cov pob txha taub hau yooj yim rau cov viscose fiber ntau.
Nyob rau hauv cov txheej txheem ua viscose fiber, feem ntau cellulose yuav tsum xub alkalized, yog li ntawd qee cov cellulose hloov nrog alkali los ua alkali cellulose. Tom qab ntawd, Alkali cellulose reacts nrog carbon disulfide, thiab tom qab cov txheej txheem sib xyaw ua ke, cov tshuaj vis discose yog thaum kawg tsim. Txoj kev daws teeb meem no yog li extruded los ntawm cov spinneret, mob siab rau hauv chav da dej sib xyaw, thiab cov viscose yog solidified thiab tsim. Tom qab kos duab thiab tom qab ua, viscose fiber yog thaum kawg tau txais.
Lub cellulose tivthaiv hauv viscose fiber muab nws ntau cov khoom zoo heev. Piv txwv li, nws muaj cov pa dej noo zoo thiab ua tsis taus pa, yog qhov yooj yim hnav, thiab tuaj yeem sib chwv nrog daim tawv; Nws tseem muaj qee yam muaj zog thiab elasticity, uas tuaj yeem ua tau raws li cov kev xav tau ntawm kev ua tiav txhua hnub.
Los ntawm kev pom kev ua lag luam, cov fiber ntau muaj ntau cov kev siv hauv cov khaub ncaws, cov ntawv sau tsev thiab lwm thaj chaw vim nws cov khoom xyaw tseem ceeb thiab cov khoom. Nkag siab nws muaj pes tsawg leeg tuaj yeem pab cov neeg siv khoom zoo dua xaiv cov tuam txhab texties zoo dua siv cov khoom lag luam uas tau txais kev lag luam zoo dua qub, thiab txhawb nqa txoj kev loj hlob ntawm kev lag luam.
