An initial study has been undertaken to determine the viability of using S-thiosulphato (Bunte salt) terminated polyethers as pigment binders. Three such polymers of different molecular mass and functionality were investigated. Two substrates were employed: wool fabric as prepared for dyeing and cotton fabric modified with a cationic polyamine. Pigments dispersed in anionic surfactants show high substantivity for the latter substrate and as a result these dispersions can be successfully applied to appropriately treated fibre by exhaust methods. In all cases high standards of washfastness were achieved without affecting the fibre handle. On cotton, each binder showed relatively low fastness to rubbing. On wool a good all-round fastness was acheived with one of the Bunte salt polyethers. The polymers also displayed excellent properties for use as dispersing, wetting and shrink-resist agents.
