The new pyrethroid, permethrin, previously shown to have high activity against textile pests, was successfully applied to wool from a conventional dye bath. The stability of permethrin to boiling aqueous conditions and to some textile testing regimes was shown to be satisfactory, although some loss on prolonged boiling did occur. Industrial trials made on both wool and wool/nylon blends are described.
