Hauv kev lag luam textile, polyester (polyester fiber) thiab viscose (txiv neej {{} Lawv txawv rau lawv cov khoom siv raw, cov khoom siv lub cev, thiab cov ntawv thov.
Cov Khoom Siv Raw thiab Cov Txheej Txheem Ntau Lawm
Polyester yog cov khoom siv hauv qab ntawm cov petrochemical kev lag luam. Nws yog tsim los ntawm polymerizing terephthalic acid thiab glycolic acid thiab cov duab puab polyester, uas yog ces yaj- spun. Nws yog ib qho hluavtaws hluavtaws tag nrho. Viscose, ntawm qhov tod tes, yog tsim los ntawm cov vaj tse ntawm cov pob zeb ntuj zoo li ntoo thiab cov paj rwb. Tom qab cov tshuaj kho mob xws li xws li alkalization, sulfonation, nws yog yaj thiab spun rau hauv cov khoom siv cellulose fiber ntau, khaws qee qhov ntawm cov khoom ntawm ntuj.
Cov Cuab Yeej Hluav Taws Xob
Polyester cov yam ntxwv zoo tshaj plaws yog lub zog siab, puas puas, thiab wrinkle tiv taus. Nws lub zog tuab tiv thaiv kev deformation, thiab nws muab tshuaj lom neeg ruaj khov, tsis kam rau cov acids, alkalis, thiab hnub ci. Txawm li cas los xij, Polyester muaj kev nqus dej tsis zoo (ib qho noo noo rov qab muaj kwv yees li ntawm 0.4%), yog qhov muaj hluav taws xob 0.4%, thiab muaj kev nplij siab tsawg. Hauv kev sib piv, Viscose tau nqus tau zoo heev noo noo ntawm 13% -15%), zoo li ib qho muag muag, thiab zoo li xav tau, ua rau nws haum rau kev ua kom zoo nkauj. Txawm li cas los xij, viscose muaj lub zog ntub dej, yooj yim shrinks thiab deforms tom qab tau siv nyob rau hauv dej, thiab tsis muaj kev txom nyem tsis kam, ua rau nws tsis tuaj yeem ruaj khov tshaj polyester.
Cov haujlwm thiab cov ntawv thov
Vim nws cov kev saib xyuas durability thiab yooj yim, polyester tau siv nyob rau hauv cov kev ua yeeb yam, xws li cov ntaub ntawv thiab rooj tog raj (xws li cov log tsheb). Viscose, ntawm qhov tod tes, feem ntau siv nyob rau hauv cov khaub ncaws zoo xws li tsho, hnav ris tsho, thiab ris tsho tiab, thiab ris tsho hauv qab. Nws tseem feem ntau sib xyaw nrog cov paj rwb thiab linen txhawm rau txhim kho cov ntaub zoo li. Tsis tas li ntawd, Viscose muaj cov xim zas xim zoo nkauj, ua rau cov xim sib zog dua li polyester.
Ib puag ncig thiab tus nqi sib txawv
Los ntawm cov kev xav tau ruaj khov, txawm hais tias Viscose yog muab tau los ntawm cov cellulose ntuj, nws tsim cov tshuaj lom neeg, uas tuaj yeem ua rau muaj kuab paug. Thaum Polyester yog cov khoom petrochemical, nws tau rov ua dua tshiab, thiab niaj hnub cov txheej txheem tau nce zuj zus hluav taws xob siv hluav taws xob. Nyob rau hauv cov nqe lus ntawm tus nqi, polyester yog feem ntau pheej yig dua Viscose vim nws ruaj khov raw khoom.
Hauv cov ntsiab lus, polyester thiab viscose txhua tus muaj lawv cov txiaj ntsig, thiab kev xaiv yuav tsum tau ua raws li cov kev xav tau, kev ua tau zoo, thiab siv cov xwm txheej, thiab siv scenarios.
