Lub kaum tsis zoo ntawm reactive dyeing muaj xws li: dyeing yam ntxwv S, E, R, F qhov tseem ceeb.Migration Performance index MI tus nqi, qib dyeing factor LDF tus nqi, yooj yim ntxhua khaub ncaws WF tus nqi, nqa lub zog Performance index BDI tus nqi / inorganic tus nqi, organic nqi (I / O) thiab solubility, kaum loj tsis rau lub ntsiab kev ua tau zoo ntawm reactive dyes xws li;Dye uptake, directness, reactivity, fixation rate, levelness, reproducibility, compatibility ntawm blended dyes thiab xim ceev ceev yog cov lus qhia tseem ceeb.
1. Kev ncaj ncees
S sawv cev rau qhov ncaj qha ntawm cov xim rau cov fiber ntau, uas yog tus cwj pwm los ntawm tus nqi adsorption thaum nws yog adsorbed rau 30 feeb ua ntej ntxiv alkali.
2. Reactivity
R sawv cev rau qhov reactivity ntawm cov xim, uas yog tus cwj pwm los ntawm fixation tus nqi tom qab 5 feeb ntawm alkali ntxiv.
3. Dye exhaustion npaum li cas
E sawv cev rau qhov qaug zog ntawm dyeing, uas yog tus cwj pwm los ntawm qhov kawg xim qhov tob thiab ntau npaum li cas.
Reactive Dyeing
Plaub, fixation tus nqi
F yog tus nqi fixation ntawm cov dye, uas yog fixation tus nqi ntawm cov dye ntsuas tom qab dyeing yog ntxuav tawm cov xim floating.Tus nqi fixation yog ib txwm qis dua tus nqi qaug zog.
S thiab R qhov tseem ceeb tuaj yeem piav qhia txog qhov dyeing tus nqi thiab cov tshuaj tiv thaiv ntawm cov dyes reactive.Lawv muaj feem xyuam rau cov xim migration thiab leveling zog.E thiab F muaj feem xyuam rau kev siv cov xim, yooj yim ntxuav thiab ceev ceev.
5. Kev tsiv teb tsaws chaw
MI: MI = C / B * 100%, qhov twg B sawv cev rau cov xim seem ntawm cov ntaub dyed tom qab kev kuaj kev tsiv teb tsaws, thiab C yog cov xim ntawm cov ntaub dawb tom qab kuaj kev tsiv teb tsaws.Qhov siab dua tus nqi MI, qhov zoo dua qib.MI tus nqi ntau dua 90% yog cov xim zas xim nrog qib zoo dyeing zog.
Rau, compatibility
LDF: LDF = MI × S / ELDF tus nqi ntau dua 70 qhia tias qib dyeing zoo dua.
RCM: Reactive dye compatibility factor, uas muaj 4 yam, S, MI, LDF thiab ib nrab dye time T ntawm reactive dye nyob rau hauv lub xub ntiag ntawm alkali.
Txhawm rau kom ua tiav qhov ua tiav thawj zaug, tus nqi RCM feem ntau txiav txim siab hauv cov kab hauv qab no, S = 70-80% hauv nruab nrab electrolyte, MI ntau dua 90%, LDF ntau dua 70%, thiab ib nrab dyeing lub sij hawm ntau dua. tshaj 10 feeb.
Xya, yooj yim ntxuav
WF: WF = 1 / S (EF), feem ntau cov fixation tus nqi ntawm reactive dyes yog tsawg dua 70%, (EF) yog ntau tshaj 15%, thiab thaum S yog ntau tshaj 75%, muaj ntau floating xim thiab nyuaj rau. tshem tawm, yog li lawv tsis tuaj yeem siv los ua cov xim sib sib zog nqus.dyeing.
8. Lub zog nqa
BDI: Lifting zog Performance index, tseem hu ua dyeing saturation tus nqi.Yog tias koj xav kom qhov tob, qhov ntau npaum li cas ntawm cov dye feem ntau nce, tab sis cov dye nrog lub zog nqa tsis zoo tsis nce qhov tob vim tias cov xim dye nce mus rau qee yam.Kev sim txoj kev: raws li qhov pom tseeb xim tawm los ntawm cov ntaub dyed ntsuas raws li tus qauv chromaticity (xws li 2% raws li tus qauv), cov xim pom tseeb ntawm dyed fabrics ntawm txhua chromaticity thiab tus qauv chromaticity nrog nce nqi ntawm dye Qhov piv ntawm saib rau xim kom muaj nuj nqis.
Cuaj, I/O tus nqi
Tus nqi I/O: Tib neeg hu ua hydrophobic (tsis yog-polar) ib feem ntawm cov organic tshuaj organic puag, thiab qhov hydrophilic (polar) yog hu ua inorganic tseem ceeb hauv paus.Tom qab ntxiv cov txiaj ntsig ntawm pawg sib txawv Tom qab ntawd faib cov lej ntawm pawg polar thiab pawg tsis-polar kom tau txais tus nqi.Tus nqi I/O sawv cev rau kev faib cov dye nyob rau hauv fiber ntau thiab dye cawv.Qhov no kuj yog ib qho tseem ceeb heev qhia txog yuav ua li cas xaiv peb lub ntsiab xim.
10. Solubility
Qhov zoo dua qhov solubility ntawm cov xim, qhov dav ntawm daim ntawv thov ntau.Muaj ob txoj hauv kev los txhim kho solubility: ib qho yog ntxiv qee cov tshuaj ntub dej nrog cov qauv tshwj xeeb kom cov dyes ntub dej sai sai hauv dej, thiab tom qab ntawd los ntawm alkyl naphthalene sulfonic acid formaldehyde condensate series dispersants los ua kom cov molecules cuam tshuam ntawm cov dye tsim ib zaug. molecule.Qhov thib ob txoj kev yog muab cov isomers ntawm reactive dyes.
Peb yog cov chaw muag khoom Reactive Dyeing, yog tias koj txaus siab rau peb cov khoom, thov koj xav tiv tauj peb.
