The distribution of surfactants in the different regions of the wool fibre has been studied by applying several novel fluorescent surfactants to wool under various conditions and studying sections of the treated fibres under the fluorescence microscope. The intercellular and cell remnant regions appear to be the preferred locations for these surfactants in the wool fibre, but various distributions can be obtained, depending on the length of the hydrocarbon chain of the surfactant and the conditions under which it is applied. The similarities in surface activity, sorption and extraction behaviour of the more typical surfactant sodium dodecyl sulphate and some of the fluorescent surfactants suggest that the former surfactant may have a similar distribution between the different regions of wool.
