  • Is the solubility of disperse dyes important for the dyeability of PES in supercritical CO2?
    Tušek, Lidija ; Golob, Vera, 1954-2005 ; Knez, Željko
    Dyeing in supercritical carbon dioxide without the use of auxiliaries is one of the newest dyeing techniques. In this paper the influence of the solubility of disperse dyes on the PES dyeing results ... in supercritical CO2 is investigated. The results show that although there is no direct correlation between the solubility of disperse dyes and the dyeability of PES fibres in supercritical CO2, the solubility of dyes makes the dyeing in supercritical CO2 possible. As in aqueous dyeing the dissolution of the dyes in supercritical CO2 is not the slowest and thus not the crucial phase of dyeing.
