New antisetting agents are proposed for wool fabrics during dyeing at the boil, viz., dithiodipropanoic acid (DTDPA) and dithiosalicylic acid (DTSA). DTDPA was found to be better than DTSA in the protection of wool during dyeing. The effect of the addition of these reagents to the dyeing bath of wool on some of its inherent mechanical properties was assessed. A proposed mechanism of reaction between the aforementioned dithiols and wool keratin is reported.
