to find appropriate systems to solubilize mothproofing agents and to promote their total exhaustion on wool fibres is essential from the environmental point of view. since the predominant mechanism for the uptake of a water-insoluble mothproofing agent by the wool fibre is analogous to that of a disperse dyestuff, a permethrin-based mothproofing agent was applied to wool fibres under the same experimental conditions as those previously found suitable for non-ionic disperse agents. a sodium sulphite/ or sodium bisulphite/cationic-surfactant aqueous medium is a suitable system to solubilize and to promote the exhaustion of a permethrin-based mothproofing agent on wool fibres. this treatment system also confers shrink-resist properties on wool fabrics.
