Cov ntsiab lus ntawm dyeing
Lub hom phiaj ntawm dyeing yog los tsim cov xim sib xws ntawm cov substrate feem ntau kom phim cov xim uas tau xaiv ua ntej.Cov xim yuav tsum zoo ib yam thoob plaws hauv lub substrate thiab yog ib qho ntxoov ntxoo uas tsis muaj unlevelness los yog hloov nyob rau hauv ntxoov ntxoo ntawm tag nrho cov substrate.Muaj ntau yam uas yuav cuam tshuam rau qhov zoo nkauj ntawm qhov ntxoov ntxoo kawg, suav nrog: kev ntxhib los mos ntawm lub substrate, kev tsim kho ntawm lub substrate (ob qho tib si tshuaj thiab lub cev), kev kho mob ua ntej siv rau lub substrate ua ntej dyeing thiab tom qab kev kho mob thov tom qab dyeing. txheej txheem.Daim ntawv thov ntawm cov xim tuaj yeem ua tiav los ntawm ntau txoj hauv kev, tab sis feem ntau peb txoj kev yog dyeing (batch), nruam (padding) thiab luam ntawv.
Vat dyes
Cov dyes yog cov dej-insoluble tseem ceeb thiab muaj tsawg kawg yog ob pawg carbonyl (C = O) uas tso cai rau cov dyes hloov los ntawm kev txo qis hauv alkaline tej yam kev mob rau hauv cov dej-soluble 'leuco compound'.Nws yog nyob rau hauv daim ntawv no uas cov xim yog absorbed los ntawm cellulose;Tom qab oxidation tom qab lub leuco compound regenerates niam txiv daim ntawv, insoluble vat dye, nyob rau hauv lub fiber.
Qhov tseem ceeb tshaj plaws ntuj vat dye yog Indigo los yog Indigotin pom raws li nws cov glucoside, Indican, nyob rau hauv ntau hom ntawm indigo cog indigofera.Vat dyes yog siv qhov chaw siab heev- thiab ntub-ceev ceev yuav tsum muaj.
Derivatives ntawm indigo, feem ntau halogenated (tshwj xeeb tshaj yog bromo substituents) muab lwm yam vat dye chav kawm xws li: indigoid thiab thioindigoid, anthraquinone (indanthrone, flavanthrone, pyranthone, acylaminoanthraquinone, anthrimide, dibenzathrone).
