Hlau Complex Dyes

Hlau complex dye yog ib tsev neeg ntawm dyes uas muaj hlau sib koom ua ke rau cov organic feem.Ntau azo dyes, tshwj xeeb tshaj yog cov muab los ntawm naphthols, tsim hlau complexes los ntawm complexation ntawm ib tug ntawm cov azo nitrogen chaw.Hlau complex dyes yog premetallised dyes uas qhia zoo affinity rau protein fibers.Nyob rau hauv no dye ib los yog ob dye molecules yog sib koom tes nrog ib tug hlau ion.Cov dye molecule feem ntau yog cov qauv monoazo uas muaj cov pab pawg ntxiv xws li hydroxyl, carboxyl lossis amino, uas muaj peev xwm ua kom muaj zog sib koom ua ke nrog kev hloov pauv hlau ions xws li chromium, cobalt, nickel thiab tooj liab.

Hlau complex dyes belongs rau ntau daim ntawv thov cov chav kawm ntawm dyes.Piv txwv li, lawv muaj nyob rau hauv cov tshuaj ncaj qha, acid, thiab reactive dyes.Thaum siv rau hauv cov txheej txheem dyeing, hlau-complex dyes yog siv nyob rau hauv pH tej yam kev mob uas yog tswj los ntawm cov neeg siv cov chav kawm ntawv thiab hom fiber ntau (wool, polyamide, thiab lwm yam).
