  • Solvent dyes

    Solvent dyes

    Ib qho hnyav dye yog ib qho xim uas yog soluble hauv cov kuab tshuaj organic thiab nquag siv los ua cov tshuaj hauv cov kuab tshuaj.Cov dyes no yog siv rau cov khoom siv xim xws li cov khoom siv quav ciab, roj nplaum, cov yas, thiab lwm yam khoom siv hydrocarbon-based nonpolar.Piv txwv li, txhua yam dyes siv hauv cov roj, piv txwv li, yuav raug suav tias yog cov kuab tshuaj dyes thiab lawv tsis soluble hauv dej.

  • Disperse dyes

    Disperse dyes

    Disperse dye yog ib hom organic uas tsis muaj ionizing pawg.Nws yog tsawg soluble hauv dej thiab siv rau dyeing hluavtaws textile cov ntaub ntawv.Disperse dyes ua tiav lawv cov txiaj ntsig zoo tshaj plaws thaum cov txheej txheem tuag tshwm sim ntawm qhov kub thiab txias.Tshwj xeeb, cov kev daws teeb meem nyob ib puag ncig 120 ° C txog 130 ° C ua kom cov dyes disperse ua tau zoo ntawm lawv cov qib siab.

    Hermeta muab cov dyes disperse nrog ntau cov tswv yim rau xim hluavtaws xws li polyester, nylon, cellulose acetate, vilene, hluavtaws velvets thiab PVC.Lawv cov nyhuv tsis tshua muaj zog ntawm polyester, vim yog cov qauv molecular, tso cai tsuas yog pastel mus rau nruab nrab ntxoov ntxoo, tab sis tag nrho cov xim tuaj yeem ua tiav thaum tshav kub hloov luam ntawv nrog disperse dyes.Disperse dyes kuj yog siv rau sublimation luam ntawv ntawm hluavtaws fibers thiab yog colorants siv nyob rau hauv lub tsim ntawm "hlau-on" hloov crayons thiab inks.Lawv kuj tuaj yeem siv rau hauv cov resins thiab yas rau saum npoo thiab siv xim dav dav.

  • Metal Complex Dyes

    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 qho 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.
