Acid dye chromatography ua tiav, nrog cov xim ci, thiab kev ceev ntawm lub hnub ci thiab kev kho ntub dej sib txawv heev nrog ntau hom dyes. Piv nrog rau cov dyes ncaj qha, cov kua qaub dyes muaj cov qauv yooj yim thiab tsis muaj ob daim ntawv cog lus ntev dua thiab cov qauv coplanar, yog li lawv tsis muaj kev ncaj qha rau cov cellulose fibers thiab tsis tuaj yeem siv rau dyeing cellulose fibers. Ntau hom kua qaub dyes muaj cov khoom sib txawv dyeing thiab ntau txoj kev dyeing vim lawv cov qauv molecular sib txawv.
Acid dyes tau muab faib ua cov kua qaub uas muaj zog, tsis muaj zog acidic, acidic mordant, thiab acidic complex dyes raws li lawv cov qauv tshuaj thiab cov xwm txheej dyeing.
Tsis muaj zog acidic dyes tuaj yeem tsim los ntawm kev nce lawv qhov hnyav molecular, qhia cov pab pawg xws li arylsulfone pawg, lossis qhia cov hlua ntev ntev hauv cov kua qaub dyes. Cov qauv molecular yog complex, thiab affinity rau wool yog ntau dua. Nws tuaj yeem dye wool hauv qhov nruab nrab tsis muaj zog acid, tsis muaj kev puas tsuaj rau cov ntaub plaub. Lub teeb xim yog tsaus dua, thiab qhov nrawm nrawm dua, tab sis tsis yog qib dyeing. Xws li tsis muaj zog acidic ci ntsa iab xiav RAW (piv txwv li CI acidic xiav 80).
Cov kua qaub dye uas tsim cov hlau complexes ntawm cov ntaub tom qab raug kho nrog qee cov ntsev ntsev (xws li chromium ntsev, tooj liab ntsev, thiab lwm yam) xws li mordant. Cov txheej txheem rau mordant dyeing yog qhov nyuaj heev, tab sis cov khoom siv dyeing nrog cov khoom zoo xws li lub teeb tsis kam, ntxuav tsis kam, thiab rub nrawm tuaj yeem tau txais, xws li acidic mordant dub T (ie CI mordant dub 11).\
Nws yog tsim los ntawm complexation ntawm tej yam acidic dyes nrog hlau xws li chromium thiab cobalt. Soluble hauv dej, nws cov khoom dyeing yog lub hnub tiv thaiv thiab muaj lub teeb pom kev zoo. Nws cov xim matrix zoo ib yam li acidic mordant dyes, tab sis hlau atoms tau nkag mus rau hauv azo dye molecules thaum npaj cov dyes. Qhov piv ntawm cov hlau atoms rau cov xim molecules yog 1: 1, yog li nws tseem hu ua 1: 1 hlau complex dyes. Mordant tsis xav tau rau dyeing. Zoo li acidic complex daj GR (ie CI acidic daj 99).
Lwm hom acidic complex dye molecule tsis muaj sulfonic pawg, tab sis muaj hydrophilic pawg xws li sulfonyl amino pawg. Qhov piv ntawm hlau atoms rau dye molecules nyob rau hauv lub molecule yog 1: 2, yog li nws tseem hu ua 1: 2 hlau complex dyes. Nws dyes nyob rau hauv nruab nrab los yog tsis muaj zog acidic media, li no nws yog hu ua ib tug nruab nrab dye. Piv txwv li, nruab nrab grey 2BL (ie CI acidic dub 60).
Acid dyes muaj xws li azo type, anthraquinone type, triarylmethane type, thiab lwm yam, tab sis feem ntau ntawm lawv yog azo dyes. Kev tsim cov acidic complex dyes zoo ib yam li cov dyes, tab sis cov txheej txheem ntawm cov hlau complexion yuav tsum tau ntxiv, xws li nruab nrab grey 2BL, uas yog thawj diazotized los ntawm 2-aminophenol 4-sulfonamide, ua ke nrog {{ 3}}acetylamino 7-naphthol, thiab tom qab ntawd complex nrog sodium chromium salicylate.
