This study investigates the influence of different finishing conditions on the amount of thermal migration and the wet fastness properties of selected red disperse dyes on polylactic acid fabrics. A comparison was made with a correspondingly finished polyethyleneterephthalate fabric, with a specific objective being to identify the conditions that would give optimum wet fastness to the polylactic acid fabric. A greater thermal migration of dye was observed on the polylactic acid compared with polyethyleneterephthalate fabric under the same heat treatment conditions, resulting in a lower level of wet fastness. The lowering in wet fastness of dyed polylactic acid fabric on processing occurs mainly as a result of thermal migration of disperse dyes during the drying stage at 110 °C.
