Thaum huab cua hloov txias, cov ntaub ntaub woolen tau muag kub dua. Tab sis thaum nws los txog rau kev luam ntaub ntaub, ntau daim ntaub yuav tsum muaj mob taub hau, vim rau daim ntaub woolen, tsoos digital cov tshuaj tiv thaiv tuaj yeem ua' tsis noj xim kiag li. Feem ntau, lawv tau txuas rau saum npoo thiab yooj yim rau ntog tawm. Yog li ntawd, cov kua qaub kua qaub xav tau rau kev luam ntaub. Vim tias tsis muaj ntau lub tsev tsim khoom rau kua qaub digital luam ntawv tam sim no, tus nqi ntawm cov kua qaub digital luam ntawv feem ntau kim.
Qhov feem ntawm cov kua qaub zas xim yog me me, kwv yees li 7%, uas yog siv rau luam ntawv ntaub plaub, nylon thiab lwm yam ntaub. Cov kua qaub yog ib hom dej-soluble zas nrog cov kua qaub hauv cov qauv, uas yog dyed hauv cov kua qaub nruab nrab. Cov kua qaub feem ntau muaj sodium sulfonate, uas yog yaj hauv dej thiab muaj xim ci thiab ua tiav chromatogram. Nws feem ntau yog siv rau zas plaub hau, txhob lo lo ntxhuav thiab nylon, ntxiv rau tawv, ntawv thiab kua mem. Nws tsis muaj lub zog xim rau cellulose fiber.
Coob leej neeg hauv khw xav tias cov kua qaub digital printing number case yog xeb, tab sis qhov tseeb, nws tsis yog txhua yam. Acid number case yog tus number case siv nyob rau hauv cov kua qaub, tsis yog tus nqi pH ntawm tus number case nws tus kheej yog acidic. Nws tuaj yeem muaj kev ruaj ntseg ntau dua li siv cov luam ntawv digital, vim tias cov kua qaub kua qaub tsis muaj teeb meem hydrolysis. Tus nqi pH ntawm cov kua qaub digital luam ntawv tus lej tuaj yeem hloov kho kom haum rau micro alkaline uas tsim nyog tshaj plaws rau lub taub hau, thaum lub tshuab hydrolysis nrawm ntawm cov tshuab luam ntawv digital nquag yuav ua kom nrawm dua nyob rau qhov xwm txheej alkaline.
Txawm li cas los xij, xim nrawm thiab ua haujlwm ntawm cov kua qaub zas xim yog qhov sib txawv heev, thiab kua qaub kua xab so ntawm qhov kub siab yog qhov hnyav heev. Acid digital luam ntaub ntaub ntxuav qhov kub tsis tuaj yeem siab dhau, txhob lo lo ntxhuav thiab ntaub plaub txog li 50 degrees, nylon txog 80 degrees. Muaj npe nrov hais hauv kev lag luam: acidity tuaj yeem' tsis piv nrog kev ua haujlwm nrawm, thaum kev ua haujlwm tuaj yeem' tsis piv nrog acidity hauv qhov ci
