Abstract

Temporarily solubilized azo disperse dyes containing ${\beta}$ -sulfatoethylsufonyl group were applied to acetate fabric and the feasibility of dispersant-free dyeing was investigated. The color yields of the dyes on acetate fabric were found to be dependent on dye bath pH as well as dyeing temperature. The optimum results were obtained at pH 6 and $80^{\circ}C$ . The dyes showed good exhaustion and levelling properties. Vinylsulfone derivatives of the dyes were prepared and applied to acetate with dispersant. Dyeing properties of the temporarily solubilized disperse dyes were similar to or better than those of the vinylsulfone dyes. The dyes showed moderate to good fastness properties on acetate.
