Reactive Dye Yam ntxwv

Reactive dyes lwm tus neeg los qhia cov yam ntxwv ntawm Reactive dyes rau koj

1. Solubility

Reactive dyes muaj cov dej zoo solubility.Qhov solubility thiab cov concentration ntawm cov dye npaj muaj feem xyuam rau tus da dej piv, tus nqi ntawm electrolytes ntxiv, dyeing kub thiab tus nqi ntawm urea siv.Qhov solubility ntawm reactive dyes yog txawv, siv nyob rau hauv printing. los yog ncoo dyeing reactive dyes, yuav tsum tau xaiv nyob rau hauv lub solubility ntawm txog 100 g / l ntau yam, qhov yuav tsum tau ntawm tag nrho cov dye dissolution, tsis muaj turbidity, tsis muaj xim point. Cov dej kub tuaj yeem ua rau kom tawg, urea muaj cov nyhuv solubilizing, ntsev, xws li Raws li sodium, sodium hmoov electrolytes yuav txo cov solubility ntawm dyes.Alkali yuav tsum tsis txhob ntxiv nyob rau tib lub sij hawm thaum lub reactive dye yog yaj los tiv thaiv hydrolysis ntawm cov dye.

2. Diffusivity

Diffusivity yog hais txog lub peev xwm ntawm cov dye mus rau hauv fiber ntau, thiab qhov kub thiab txias yog conducive rau diffusion ntawm dye molecules.Cov dye nrog loj diffusion coefficient muaj siab cov tshuaj tiv thaiv tus nqi thiab cov xim fixation efficiency, thiab cov degree ntawm evenness thiab nkag mus rau hauv lub zoo. .Qhov diffusivity nyob ntawm tus qauv thiab qhov loj ntawm cov dye.Ntawm cov fiber ntau affinity ntawm cov dye los ntawm fiber ntau adsorption quab yuam yog muaj zog, diffusion yog ib qho nyuaj, feem ntau yog los ntawm qhov kub thiab txias kom ceev cov dye diffusion.Qhov diffusion coefficient ntawm dye txo thaum electrolyte yog ntxiv rau hauv cov tshuaj zas xim.

3. Kev ncaj ncees

Directness yog hais txog lub peev xwm ntawm reactive dyes kom absorbed los ntawm fibers nyob rau hauv cov tshuaj dye.Qhov solubility ntawm reactive dyes feem ntau tsis tshua muaj ncaj, nruam ncoo dyeing thiab luam ntawv yuav tsum tau xaiv tsawg direct ntau yam.Rau dyeing khoom nrog loj da dej piv, xws li Txoj hlua zoo li dyeing thiab Hank dyeing, high directness dyes yuav tsum nyiam dua.Rolling yob (txias dov) dyeing txoj kev, cov dyeing yog pauv mus rau fiber ntau los ntawm dip dov, kuj nrog ib tug me ntsis qis directness ntawm cov dye yog ib qho yooj yim kom sib npaug. dyed, ua ntej thiab tom qab xim sib txawv yog tsawg, hydrolysis dye yog yooj yim los ntxuav.

4. Reactivity

Lub reactivity ntawm reactive dyeing feem ntau yog hais txog cov dyeing thiab cellulose hydroxy cov tshuaj tiv thaiv muaj peev xwm muaj zog thiab tsis muaj zog, muaj zog Reactive dye nyob rau hauv chav tsev kub, nyob rau hauv lub tsis muaj zog puag xws li fixation yuav ua tau, tab sis cov tshuaj tiv thaiv ntawm dye stability kuj tsis zoo, yooj yim rau hydrolysis plam Dyeing peev xwm.Reactive dyes yuav tsum tau khi nrog cellulose ntawm qhov kub thiab txias, los yog siv lub zog alkali los qhib cov hydroxyl pawg ntawm cov xov paj fiber ntau, kom cov tshuaj tiv thaiv dye yog tsau rau fiber ntau.

Kev loj hlob ntawm dyes

Yuav kom ua tau raws li qhov xav tau ntawm dyeing, dyes tshiab tau tshwm sim tas li nyob rau hauv xyoo tas los no.Txoj kev loj hlob ntawm cov dyes tshiab yog tsuas yog ua kom tau raws li cov hauv qab no:

(1) hloov cov xim tha xim thiab tsim cov xim zoo nkauj;

(2) hloov mus rau qhov xav tau ntawm cov fibers tshiab thiab ntau cov khoom siv dyeing;

(3) hloov mus rau cov kev xav tau ntawm cov cuab yeej tshiab thiab cov khoom siv tshiab ua tiav;

(4) kom ua tau raws li qhov xav tau ntawm kev ua haujlwm zoo, txuag dej thiab txuag hluav taws xob.

Txoj kev loj hlob ntawm reactive dyes suav nrog cov chromophores tshiab, pawg reactive thiab lawv cov kev sib txuas hauv cov molecules, thiab kev sib xyaw ntawm ligands thiab cov xim sib txawv.Tsis tas li ntawd, tom qab ua tiav ntawm kev lag luam dyes tau zoo heev.Kev ua tau zoo ntawm cov dyes tshiab reactive yog pom nyob rau hauv:

(1) siab xim, siab ncaj thiab fixation;

(2) ceev ceev, nrog rau ceev ceev rau lub hnub, kev sib txhuam, hws, chlorine thiab xab npum, thiab lwm yam.;

(3) tsawg ntsev, tsawg alkali los yog nruab nrab staining thiab fixation;

(4) ib puag ncig tus phooj ywg, tsis muaj teeb meem tshuaj tsw qab amines, hnyav hlau, formaldehyde thiab lwm yam khoom;

(5) zoo levelness, reproducibility thiab compatibility.
