1. Acid dyes
Acid dyes yog ib hom dej-soluble dyes nrog cov qauv acidic pawg uas dye hauv acidic media. Feem ntau cov kua qaub dyes muaj sodium sulfonate, uas yog soluble hauv dej thiab tsim cov xim ci nrog cov xim tiav. Acid dyes muaj cov xim ua tiav thiab cov xim ci, thiab lawv lub teeb nrawm nrawm thiab ntub dej nrawm nrawm sib txawv heev nyob ntawm hom dye. Piv nrog rau cov dyes ncaj qha, cov kua qaub dyes muaj cov qauv yooj yim thiab tsis muaj cov khoom sib txuas ntev ntev thiab cov qauv isohedral. Yog li ntawd, lawv tsis muaj kev ncaj qha rau cellulose fibers thiab tsis tuaj yeem siv rau dyeing cellulose fibers. Ntau hom kua qaub dyes muaj qhov sib txawv dyeing zog vim lawv cov qauv molecular sib txawv, thiab cov txheej txheem dyeing siv txawv.
Kev Siv: Feem ntau yog siv rau dyeing wool, txhob lo lo ntxhuav thiab nylon, nrog rau tawv, ntawv, number case, thiab lwm yam. Feem ntau, tsis muaj xim quab yuam yog exerted ntawm cellulosic fibers.
2. Basic dyes
Basic dyes kuj hu ua ntsev-raws li dyes. Cov dyes uas tsim cov cationic dyes tuaj yeem sib cais hauv cov tshuaj aqueous thiab raug cais raws li cationic dyes. Nws yog tus cwj pwm los ntawm cov xim ci, muaj zog fluorescence (feem ntau yog sawv, daj, txiv kab ntxwv, thiab lwm yam), muaj zog tinting zog, me me xim, thiab xim nplua nuj. Nws muaj cov xim tsis zoo thiab lub teeb nrawm, tab sis nws muaj qhov nrawm nrawm rau acrylic fiber (polyene fiber). Basic dyes tsis xim cellulose fibers
Kev Siv: Vim yog cov xim tsis zoo thiab xim ceev ntawm fibers dyed nrog alkaline dyes, nws tsis tshua muaj siv rau dyeing fabrics. Nws yog tsuas yog siv rau hauv cov xim thiab kev tsim cov ntawv sau thiab ntawv.
