1 Adsorption isotherms of two neutral dyeing 1:2 chromium complex dyes without ionized substituents on wool, acetylated wool and silk have been determined. 2 In principle, the dyeing mechanism of these dyes on these fibres shows the same characteristics as on polyamides investigated in former papers:two processes, namely salt formation with basic groups of the fibre and a solution mechanism, procecd simultaneously. On wool, the solution mechanism is of minor importance. 3 The affinity of one of these dyes for wool via the salt binding mechanism has been calculated. It is lower than its affinity for nylon 66.
