Kev cuam tshuam ntawm leveling tus neeg sawv cev ntawm dyeing affinity.

Dyeing affinity nyob ntawm cov qauv thiab cov khoom ntawm dyes thiab fibers. Thaum cov qauv thiab cov khoom ntawm dyes thiab fibers nyob ze rau ib leeg, ob qho yooj yim rau yaj thiab dyeing affinity siab dua. Qhov thib ob, nws muaj feem xyuam rau cov txheej txheem dyeing, tshwj xeeb tshaj yog kub. Dyeing kub nce, dyeing saturation tus nqi nce, thaum adsorption isotherm nqes hav txo, uas yog, affinity txo nrog qhov nce ntawm kub. Yog vim li cas yog qhov solubility ntawm disperse dyes nyob rau hauv dej nce sai nrog qhov kub thiab txias dua nyob rau hauv fibers. Cov dyeing saturation tus nqi ntawm disperse dyes kuj txawv nrog cov thermal chaw ua ntej dyeing.
Tsis tas li ntawd, affinity kuj cuam tshuam los ntawm lwm yam khoom siv hauv chav da dej, xws li dispersants, levellers thiab cov nqa khoom. Yog hais tias cov auxiliaries no nce lub solubility ntawm dyes nyob rau hauv cov tshuaj dye, qhov kev faib coefficient yuav txo thiab affinity ntawm dyes rau fibers yuav txo. Qhov tseeb, feem ntau pom tau tias cov adsorption isotherm ntawm disperse dyes tsis yog ib txoj kab ncaj nraim, uas tej zaum yuav yog vim lub xeev complex ntawm dyes nyob rau hauv kev daws. Lub xeev thiab qhov tseeb dissolution ntawm dyes nyob rau hauv lub amorphous cheeb tsam ntawm lub fiber kuj txawv: lawv yuav undergo localization adsorption, thiab kev sib cuam tshuam ntawm cov xim molecules yuav ua rau lawv aggregate nyob rau hauv lub void ntawm fiber, uas ua rau lub adsorption isotherm deviating los ntawm cov linear. yam ntxwv.
