Studies on the Stabilities of Dyes in One Bath Dyeing Systems of Polyester/cotton Blends with Disperse Dyes/Reactive Dyes (I) -Dispersibility and Dyeability of Disperse Dyes -

폴리에스테르/면 혼방품-분산염료/반응염료 1욕 염색계에서의 염료의 안정성에 관한 연구(I) -분산염료의 분산성과 염착성-

Particle size distribution of disperse dyes in the solution of disperse-reactive dye mixture solution was studied. Particle size of dyes in the dye mixture solution was generally bigger than that in the solution containing single dye. The presence of salt in low temperature disperse dyebath increased aggregation of the dye and this tendency became greater as the hydrophobic property of the dye increased. However, with the increase of dyebath temperature, the presence of salt made disperse dyes more soluble into the micelles.
