Muaj ntau tus oxidants muaj. Kev daws lub npuag rau hauv cov tshuaj hydrogen peroxide alkaline nrog rau 3 mus rau 5 g / L thiab tom qab ntawd muab cub li 2 mus rau 3 feeb tuaj yeem txhawb kev ua kom tsis zoo ntawm cov hmoov txhuv nplej siab thiab polyvinyl cawv thiab muaj qee yam tshuaj dawb rau ntawm daim ntaub. Thaum tsim nyog nrog sodium hyposulfite, cov ntaub npuag nrog paddled nrog sodium hyposulfite tov nrog pH ntawm 9.5 rau 10.5 thiab qhov ua tau zoo ntawm 0.5 txog 1.5 W, thiab stacked nyob rau hauv chav tsev kub rau txog 20 feeb los tiv thaiv methyl fiber. Cov ntaub sizing nrog lub tiaj, cov hmoov txhuv nplej siab lossis polyvinyl cawv muaj qhov kev xav zoo zoo. Hyaluronic acid persulfate ntsev los yog ntsev ntsev kuj muaj cov txiaj ntsig zoo, tab sis nws yooj yim kom ua rau cov cellulose fiber ntau txhuam.
1. Lub Neej Ntshaw
Kev tsim lub siab yog txheej txheem tseem ceeb ua ntej ua qauv ua kom tawv nqaij thiab txau tawv. Nws tuaj yeem tsis tsuas yog tshem tawm sizing ntawm cov ntaub, tab sis kuj tshem tawm qee qhov tsis huv los ntawm paj rwb ntaub. Desizing yuav tsum tau xaiv raws li cov qauv sib xyaw thiab cov yam ntxwv ntawm cov ntaub ntawm cov ntaub los txhim kho cov nyhuv desizing. Tom qab cov ntaub yog qhov tseem ceeb, nws yog feem ntau yuav tsum tau tias qhov kev ua kom zoo siab tau siab dua 80%, lossis tus nqi ntawm cov pliaj ntawm cov npuag tsawg dua 1%.
2. Kev Raug Txom Nyem
Kev rho tawm tuaj yeem tshem tawm cov kab mob ntawm cottonseed hull thiab cellulose thiab cov nplaim ntu ntawm daim ntaub, kom cov ntaub paj rwb tuaj yeem tau txais cov tsos zoo thiab nqus dej, thiaj li pab txhawb kev ua haujlwm tom qab. Viscous fiber ntau thiab cov nplua nuj fiber ntau muaj tsawg impurities vim lub caustic sis dej qab zib thiab tshuaj dawb hauv cov txheej txheem kev tsim khoom, feem ntau tsuas yog xav tau kev ntshaw thiab tshuaj dawb thaum ua cov txheej txheem kom tshem tawm sizing thiab stains ntawm cov ntaub los txhim kho ntxiv kom dawb, Tsis tas yuav xyaum. Vinylon, polyester thiab wax fiber tsis tas yuav tsum tau smelted. Lawv tsis tas yuav tsum tau smelted nrog viscose, fiber ntau-blended ntaub los yog polyester-siv quav ciab cov ntaub, tab sis cov ntaub ua ke nrog paj rwb yuav tsum tau ua kom tiav vim tias muaj ntau cov xov paj rwb xyaum ua. Txawm li cas los xij, vinylon muaj xim daj thiab ua tawv tawv tom qab kev kho mob ntev ntev hauv qab qhov kev txiav txim siab ntawm qhov kub siab tshaj tawm alkali; polyester fiber yuav yauv sib txawv qib ntawm etching ntawm lub fiber ntau hauv qhov kub siab concentrated alkali. Tom qab pleev txhuam, cov paj rwb uas ntim tshuab ib nrab yuav tsum muaj cov nyhuv capillary siab tshaj 8 cm / 30min.
3. Tshuaj dawb
Tom qab muab nplawm, Mianzhi feem ntau nyob hauv cov xim ntuj thiab qee qhov kev ua kom tsis muaj zog, uas cuam tshuam rau lub ntsej muag dawb thiab vividness ntawm cov khoom tiav. Yog li, tsuas yog qee cov khoom lag luam tsaus nti, tshuaj dawb yuav tsum. Kev lim tsis tuaj yeem tsis tsuas yog tshem tawm cov pigments, tab sis kuj tshem tawm impurities xws li cottonseed hulls thiab cov pa nitrogenous kom sib txawv qib. Cov neeg dawb ntawm cov khoom tiav ib nrab tom qab tshuaj dawb yog feem ntau xav tau kom mus txog
Ntau dua 85% (100% nrog BaSO4).
