Qhov nrov tshaj plaws Direct Sky Blue 5B Rau Dyeing Ntawv

Cov yam ntxwv tseem ceeb ntawm Direct Sky Blue 5B suav nrog:
A.Blue hmoov, soluble nyob rau hauv dej, liab xiav kua, siab dyeing, yooj yim rau kev khiav lag luam, siab ncaj qha mus rau cellulose, tsis tas yuav siv tshuaj colouring, insoluble nyob rau hauv organic solvents.
B.Thaum dyes dye cellulose fibers, ntsev ua raws li ib tug accelerator.Lub dyeing txhawb mechanism yog tias cov dyeing ncaj qha dissociated rau pigment anion nyob rau hauv cov kev daws rau dye cellulose fiber, cellulose fiber kuj tsis zoo nqi nyob rau hauv dej, muaj ib tug nqi repulsion ntawm cov dye thiab fiber, ntxiv ntsev nyob rau hauv lub dyeing tov, tuaj yeem txo tus nqi repulsion, txhim kho tus nqi dyeing thiab dyeing feem pua.Cov nyhuv ntawm cov xim dye ncaj qha txawv txawv.Cov nyhuv ntsev ntawm cov dyes ncaj qha uas muaj ntau pawg sulfonic acid nyob rau hauv cov molecules yog qhov tseem ceeb, yog li cov ntsev yuav tsum tau ntxiv rau hauv cov khoom siv kom ntseeg tau tias cov xim zoo sib xws.Direct dyes nrog qis feem pua ​​​​ntawm cov dye xav tau ntsev ntau dua, thiab cov nyiaj tshwj xeeb tuaj yeem txiav txim siab raws li qhov ntau thiab tsawg dyeing qhov tob.Tus nqi ntsev yuav tsum raug txo kom tsim nyog rau cov khoom siv xim xim uas muaj qhov sib npaug siab, kom tsis txhob muaj qhov tsis sib xws hauv zos thiab xim tsis xws luag.
C. Nws yog tsuas yog siv rau dyeing cellulose fibers xws li paj rwb thiab viscose.Nws kuj tseem siv tau rau dyeing ntawv thiab biology nrog rau xim xim zaj duab xis.Nws kuj tseem siv tau los ua tus cwj mem.Direct Sky Blue 5B yog ib qho tseem ceeb xiav dyes siv tam sim no, thiab nws yog siv rau dyeing thiab luam ntawv hauv viscose ntaub.Ntxiv rau kev siv ib leeg, feem ntau nrog ncaj qha ntsuab B, tsaus ntsuab B, jujube GB, tsaus xim av M thiab tooj liab xiav 2R ncaj qha dye xim ua ke.
