Iimpawu kunye neeNzuzo
- Uzinzo olugqwesileyo kunye nokusabalalisa.Inokusetyenziswa njenge-colloid ekhuselayo kwinkqubo yokudaya.
- Izinzile kwi-asidi, i-alkali, i-electrolyte kunye namanzi anzima.
- Inyibilika ngokulula emanzini.Igwebu eliphantsi.
- Kulula ukuyisebenzisa.

Imigaqo yokudaya
Injongo yokudaya kukuvelisa umbala ofanayo we-substrate ngokuqhelekileyo ukuhambelana nombala okhethwe kwangaphambili.Umbala kufuneka ube yinto efanayo kuyo yonke i-substrate kwaye ube ngumthunzi oqinileyo ngaphandle kokungahambi kakuhle okanye utshintsho kumthunzi phezu kwe-substrate yonke.Kukho izinto ezininzi eziza kuba nefuthe ekubonakaleni komthunzi wokugqibela, kubandakanywa: ukuthungwa kwe-substrate, ukwakhiwa kwe-substrate (zombini iikhemikhali kunye nezomzimba), unyango lwangaphambili lusetyenziswe kwi-substrate ngaphambi kokudaya kunye nokunyangwa emva kokusetyenziswa emva kokudaya. inkqubo.Ukusetyenziswa kombala kunokufezekiswa ngeendlela ezininzi, kodwa iindlela ezintathu eziqhelekileyo ziyi-exhaust dyeing (i-batch), eqhubekayo (i-padding) kunye nokushicilela.
Idayi zeVat
Ezi dayi ngokwesiseko azinakunyibilika emanzini kwaye ziqulathe ubuncinci amaqela amabini e-carbonyl (C=O) enza ukuba idayi iguqulwe ngendlela yokunciphisa phantsi kweemeko zealkaline ibe yi-'leuco compound' edibeneyo yamanzi.Kukule fomu ukuba idayi ifunnwe yi-cellulose;Ukulandela i-oxidation elandelayo ikhompawundi ye-leuco iphinda ivelise imo yomzali, idayi yevat enganyibilikiyo, ngaphakathi kwifiber.
Idayi yevat yendalo ebaluleke kakhulu yi-Indigo okanye i-Indigotin efunyenwe njengeglucoside yayo, i-Indican, kwiindidi ezahlukeneyo ze-indigo plant indigofera.Idayi zeVat zisetyenziswa apho ukukhanya okuphezulu kakhulu kunye nokukhawuleza kweempawu ezimanzi kufuneka.
Izinto eziphuma kwi-indigo, ubukhulu becala i-halogenated (ingakumbi i-bromo substituents) zibonelela ngezinye iindidi zedayi ye-vat eziquka: i-indigoid kunye ne-thioindigoid, i-anthraquinone (i-indathrone, i-flavanthrone, i-pyranthone, i-acylaminoanthraquinone, i-anthramide, i-dibenzathrone kunye ne-carbazole).
