Abstract: The invention provides a method for preparing an insecticidally treated textile having improved properties. A novel combination of an insecticide and certain polymeric binder(s) or dye fixatives is used to coat and/or impregnate fabric via a combination of application methods used in the textile industry. The insecticide-binder or insecticide-dye fixative combination and the method by which it is applied to the textile yield a coated fabric and, ultimately, finished goods with improved wash durability of the insecticide over several launderings and prolonged insecticidal efficacy.
