Qee cov dyes (ncaj, kua qaub, acidic nruab nrab, reactive, thiab lwm yam) yog complex nrog hlau ions (tooj liab, cobalt, chromium, nickel ions) los tsim ib chav kawm ntawm dyes.Nws yog soluble nyob rau hauv dej thiab nws cov khoom dyeing yog ntau resistant rau tshav ntuj los yog ntxuav.Piv txwv li, ncaj qha tshav ntuj resistant emerald xiav GL (Lionolblue GS) thiab acid complex xiav GGN (Acid Complex Blue GGN), thiab lwm yam.
1: 2 Hlau complex dyes muaj ntau yam kev siv, uas tuaj yeem muab faib ua hauv qab no:
a) Kev siv hauv cov txheej txheem (inks, xim).Piv txwv li, xim ntoo, luam ntawv number case, hlau nto xim, thiab lwm yam.
b) Daim ntawv thov hauv cov yas, feem ntau yog siv los ua pob tshab (fluorescent) xim rau cov yas
c) cov ntawv tshwj xeeb, xws li cov ntawv siv quav ciab lossis cov khoom siv tswm ciab xim, khau polish xim, tawv xim pleev xim, tshuaj pleev ib ce thiab lwm yam xim.
1: 2 Hlau complex dyes yog dyes uas yog soluble nyob rau hauv cov organic solvents xws li aromatics, esters, styrene, methylmethopropionate, thiab lwm yam.Cov organic solvents tau hais los saum toj no yuav luag insoluble hauv dej.
Cov xim tseem ceeb ntawm 1: 2 Hlau complex dyes yog: daj, txiv kab ntxwv, liab, xiav, dub, thiab fluorescent liab (peach).Kuj muaj hlau complex dye hu ua 'China Red' nyob rau hauv kev ua lag luam nrog cov xim ci heev.Nws tseem yog lub npe hu ua National Flag Red.
