Cov kuab tshuaj dyes thiab disperse dyes yog ob qho tib si siv rau xim ntau yam ntaub ntawv, tab sis lawv txawv ntawm lawv cov tshuaj muaj pes tsawg leeg, cov khoom, thiab cov khoom siv uas lawv tsim nyog. Nov yog qhov sib txawv tseem ceeb ntawm cov kuab tshuaj dyes thiab disperse dyes:
1, Tshuaj muaj pes tsawg leeg:
Solvent Dyes: Cov dyes feem ntau yog soluble hauv cov kuab tshuaj organic, xws li cawv, acetone, thiab hydrocarbons. Lawv tau tsim los ua kom yaj hauv cov kuab tshuaj no, tsim cov tshuaj uas tuaj yeem siv rau xim ntau yam ntaub ntawv, suav nrog plastics, waxes, thiab qee cov hluavtaws fibers.
Disperse Dyes: Disperse dyes, ntawm qhov tod tes, yog tshwj xeeb tsim los rau dispersed hauv dej, thiab lawv yog insoluble hauv organic solvents. Lawv xav tau kev siv cov tshuaj tua kab mob thiab cov cua sov kom sib cais sib npaug hauv dej thiab cov khoom siv hluavtaws xws li polyester, acetate, thiab nylon.
2, Lub Hom Phiaj Khoom:
Solvent Dyes: Cov dyes feem ntau yog siv rau cov khoom siv xim uas yog soluble lossis tuaj yeem yaj hauv cov kuab tshuaj organic, xws li yas resins, waxes, thiab qee hom hluavtaws fibers xws li acetate. Lawv tsis haum rau dyeing ntuj fibers lossis cov ntaub ntawv uas tsis yooj yim yaj hauv cov kuab tshuaj organic.
Disperse Dyes: Disperse dyes yog tsim tshwj xeeb rau dyeing hluavtaws lossis hydrophobic (water-repellent) fibers, nrog rau polyester, acetate, thiab nylon. Lawv tsis zoo rau dyeing ntuj fibers xws li paj rwb los yog ntaub plaub.
3, Daim Ntawv Thov:
Solvent Dyes: Cov xim dyes feem ntau yog siv rau hauv daim ntawv daws teeb meem, xws li cov kua dye tov los yog ua cov tshuaj pleev xim rau hauv cov kuab tshuaj. Lawv tuaj yeem siv los ntawm txoj hauv kev xws li dip dyeing, txau, lossis immersion hauv qhov hnyav da dej.
Disperse Dyes: Disperse dyes yog siv rau hauv dyeing thiab luam ntawv ntawm hluavtaws fibers. Lawv xav tau cov txheej txheem cua sov kom nkag mus thiab ua raws li cov fibers zoo. Cov txheej txheem siv rau kev siv cov dyes disperse muaj xws li kub kub dyeing thiab sublimation luam ntawv.
4, Xim ceev:
Solvent Dyes: Solvent dyes paub txog lawv cov xim ceev ceev, uas txhais tau hais tias lawv tswj lawv cov xim thaum lub sij hawm thiab tiv thaiv fading, txawm tias thaum raug lub teeb thiab ib puag ncig yam.
Disperse Dyes: Disperse dyes kuj muab cov xim zoo nrawm ntawm cov hluavtaws fibers, ua rau lawv haum rau cov ntawv thov uas khaws xim yog qhov tseem ceeb, xws li hauv kev lag luam textile thiab khaub ncaws.
Hauv cov ntsiab lus, qhov sib txawv tseem ceeb ntawm cov kuab tshuaj dyes thiab disperse dyes nyob rau hauv lawv cov khoom solubility thiab hom ntawm cov ntaub ntawv uas lawv tau tsim los xim. Cov kuab tshuaj dyes yog soluble nyob rau hauv cov kuab tshuaj organic thiab yog siv rau ntau yam ntaub ntawv, nrog rau tej yam hluavtaws fibers, thaum disperse dyes yog tsim los siv dej thiab yog tshwj xeeb yog npaj rau coloring hluavtaws, hydrophobic fibers.
