Evaluation of Some Reactive Disperse Dyes for Sublimation Transfer Printing on Wool

The transfer printing of wool by the sublimationmethod using a number of low-molecular-weight dyes containing chloro- and bromo- acetyl, chloroacetamido, chloro- and bromo-propionamido, 2- bromoacryloyl, 2-chloroethylamino and epoxy groups has been examined. To achieve build-up of the dyes to heavy depths, it was necessary to pretreat the wool with a polymer of surfactant and to steam the prints after transfer of the designs. Several dyes exhibited good fastness properties on pure wool and on a wool-polyester blend fabric
