Cia mus rau lub khw niaj hnub "Npuag" - peb ob lub qhov muag khiav dav, peb ua tsis taus pa raug tshem tawm hauv kev qhuas ntawm qhov peb pom. Yog li yuav ua li cas kom nkag siab qhov ntau xim ntawm cov ntaub ntawm cov khoom sib txawv? Qhov deb, qhov nyuaj dua nws ua kom paub qhov txawv ntawm cov khoom siv dag zog thiab ntuj tsim los ntawm kev kov, saib daim ntawv lo, thiab muaj ntau thiab ntau cov lus txawv teb chaws: modal, spun, tencel, polynosic, cupro, rayon.
Cov ntaub ntawm cov fibers no yog dag. Tab sis nyob rau hauv kev ncaj ncees, nws yuav tsum tau muab sau tseg hais tias tej yam ntuj tso khoom xws li cellulose yog siv rau nws siv.
Rayon yog ib daim ntaub uas tau hais tseg hauv xyoo 1664 los ntawm tus kws tshaj lij Hooke los ntawm Askiv. Nyob rau hauv tus txheej txheem ntawm kev ua rayon, lub ntuj technology ntawm tig mulberry cellulose rau nyias nyias xov los ntawm ib tug silkworm yog rov ua dua.
Nws feem ntau lees paub tias lo lus no tau tshwm sim thaum ntxov li xyoo 1924 hauv Tebchaws Meskas, thiab ua ntej nws hu ua rayon. Nco ntsoov tias lub npe los ntawm lus Askiv lo lus ray - ib txoj kab hluav taws xob, zoo li hinting ntawm cov xim ci ntawm viscose thiab xaus ntawm lo lus ntawm - los ntawm cov tsiaj ntawv kawg hauv lo lus paj rwb, qhia txog nws qhov zoo ib yam li paj rwb.
Thiab tsis ntev los no ntawm daim ntawv lotau sau xyoob, qhia tias cov khoom siv raw rau kev tsim cov ntaub no yog xyoob. Tom qab ntawd US Tsoom Fwv Teb Chaws Trade Commission tau ceeb toom tias txawm tias xyoob yog cov khoom siv raw rau kev tsim cov rayon, txawm li cas los xij, thaum lub sij hawm ua tshuaj, cov ntaub tsis muaj dab tsi ua nrog nws.
Thaum ua cov ntoo ntoo, cov fiber ntau tshaj plaws los ntawm cov khoom siv dag zog uas twb muaj lawm - qhov no yog rayon. Cov ntaub, uas muaj cov khoom ntawm viscose, yog qhov tsim nyog rau cov neeg uas xav hnav khaub ncaws zoo. Xws li cov kev xav tau muaj xws li hygroscopicity, zoo breathability, softness. Ib qho tseem ceeb ntawm cov ntaub yog tias nws yog anti-static, txhais tau tias nws tsis tuaj yeem tsim hluav taws xob zoo li qub.
Ua tsaug rau qhov no, cov khaub ncaws ua los ntawm viscose fiber ntau qab ntxiag rau lub cev thiab nyiam hnav. Zoo-dyed viscose yeej ib txwm muaj xim nplua nuj thiab ci. 95% viscose thiab 5% lycra nrog rau qhov sib txawv ntawm ib qho kev coj los yog lwm qhov - qhov no yog qhov feem ntau lees txais cov khoom ntawm knitted viscose ntaub, ua tsaug rau cov khaub ncaws tsis ncab lossis deform. Cov ntaub knitted no yog siv los xaws ntau hom khaub ncaws - los ntawm lub teeb blouses thiab T-shirts rau trousers thiab capri ris, Yog hais tias viscose muaj nyob rau hauv muaj pes tsawg leeg ntawm paj rwb, cov yam ntxwv ntawm xws li ntaub, uas yog, noo noo absorbing ntsuas, yuav ntau dua li cov paj rwb ntshiab.
Qhov tsis zoo ntawm rayon tuaj yeem txiav txim siab tias kev ntxuav cov khoom ntawm cov ntaub no yuav tsum tau ua tib zoo ua tib zoo nrog cov tshuaj detergents, nyiam dua los ntawm tes. Zoo tsis twistlawv nyob rau hauv ib lub centrifuge, thiab nyem lawv tawm, qhwv lawv nyob rau hauv ib tug phuam los yog tsis ntau nrog koj txhais tes, qhuav lawv, kis lawv tawm ntawm ib tug tiaj tus. Tsis tas li ntawd, thaum xaws khaub ncaws los ntawm rayon, yuav muaj ntau ntxiv ntawm cov npoo ntawm cov ntaub.
Rayon yog cov ntaub (viscose silk) ua los ntawm cov ntoo pulp. American labeling yuav siv lo lus rayon, thaum European labeling yuav siv viscose. Yog li ntawd, thaum koj pom cov ntawv sau zoo li no, koj tuaj yeem paub tseeb ntawm qhov zoo thiab ib puag ncig tus phooj ywg ntawm cov ntaub, uas ntau tus neeg tsim qauv hauv ntiaj teb nto moo ua haujlwm nrog.
