Disperse Dyeing txheej txheem

Thaum dyeing ntawm qhov kub thiab txias.Disperse dyeing txheej txheem ntawm polyester fiber.

Muab faib ua plaub theem

1. Disperse dyes migrate los ntawm cov tshuaj dye mus rau fiber ntau nto vim qhov txawv ntawm concentration:

2. Disperse dyes yog adsorbed rau fiber ntau nto:

3. Disperse dye penetrates rau hauv fiber ntau:

4. Disperse dyes migrate hauv fiber ntau.

Yog li kom ua tiav cov txiaj ntsig zoo qib thiab hauv cov txheej txheem ntawm plaub theem no.

Daim ntawv ntawm disperse dyes ntawm dye cawv thiab fiber

Nws tau dhau los ua ntau yam kev hloov pauv:

Ua ntej, disperse dyes yog dispersed nyob rau hauv ib tug aqueous tov nyob rau hauv daim ntawv ntawm hais (ntau ib tug crystal dye molecules) los ntawm ib tug dispersant.Tsim ib qho system dispersed.Qhov thib ob, raws li qhov kub thiab txias, qhov thermal txav ntawm cov xim molecules intensifies thiab maj mam sib txawv rau hauv ib lub xeev crystal.Thaum kawg, cov xim disperse nyob rau hauv ib lub xeev siv lead ua nkag mus rau hauv cov fiber ntau, hloov mus rau hauv cov fiber ntau thiab mus txog qhov sib npaug.Cov dye molecules nyob rau hauv cov dye cawv tsis tu ncua nkag mus rau hauv fiber, thiab ib qho kev faib ua feem ntawm disperse dye nyob rau hauv lub fiber yog kis los ntawm fiber mus rau dye cawv.

Dyeing yog sib npaug ntawm txhua theem ntawm cov txheej txheem dyeing ntawm disperse dyes.Yuav ib txwm muaj ib qho crystal disperse dyes thaum lawv tau txais lub zog txaus kom tshem tawm cov kev txwv ntawm cov dispersant thiab ua ke nrog lwm cov crystal disperse dyes los tsim cov muaju loj (los yog recrystallization), ib zaug cov crystals recrystallized loj txaus.Dye me ntsis los yog stains yuav raug tsim, uas tuaj yeem txhim kho qib ntawm plasticization ntawm fiber ntau, uas yuav pab kom cov txheej txheem dyeing kom tiav sai li sai tau.Tsis tas li ntawd, solubility ntawm disperse dyes nyob rau hauv dej yog tsawg heev, thiab cov dyes nyob rau hauv lub dyeing cawv yuav tsum tau dispersed nyob rau hauv lub dyeing da dej raws li ib tug ncua kev kawm ntawv los ntawm ib tug loj npaum li cas ntawm dispersant thaum dyeing polyester fibers.Txhawm rau kom ua tiav cov nyhuv dyeing zoo dua, qee qhov nyiaj dyeing auxiliary feem ntau yog ntxiv.

Lub luag haujlwm ntawm dyeing auxiliaries hauv cov txheej txheem dyeing

a.Ua kom zoo dua cov solubility ntawm disperse dyes:

b.Txhawb cov adsorption ntawm disperse dyes ntawm fiber ntau nto:

c.Plasticize cov fiber ntau los yog nce qib ntawm o.Ua kom lub diffusion ceev ntawm disperse dye hauv fiber ntau:

d.Txhim kho qhov dispersion stability ntawm cov xim.

Feem ntau, cov auxiliaries siv nyob rau hauv high-temperature thiab high-pressure dyeing ntawm polyester fibers muaj ib tug cab kuj uas plasticizes lub fiber, ib tug nto active tus neeg sawv cev uas solubilizes disperse dyes los yog stabilizes lub dye suspension, thiab lwm yam dyeing auxiliaries muaj ib tug tseem ceeb heev nyhuv ntawm lub dyeing ntawm polyester fibers.
