A quantitative study has been made of the effect on dye transfer in wool printing of adding solvents to the print paste. Experimental procedures have been devised for ( a ) producing the printed mark, ( b ) transferring dye from paste to substrate, ( c ) removing “unfixed” dye, and ( d ) estimating dye “fixed” on the fibre, under standardised and reproducible conditions. Addition of benzyl alcohol to print pastes containing Carbolan Brilliant Blue 2R (C.I. Acid Blue 140) and a 2: 1 dye‐metal complex dye greatly increased the rate of dye fixation, but the effect was very much less marked with the highly sulphonated dye Wool Blue RL (C.I. Acid Blue 92). The experimental results suggest that the underlying mechanism is the same as that in solvent‐assisted dyeing processes.
