ABSTRACT OF THE DISCLOSURE: A process for imparting antibacterial activity to cellulosic textiles is disclosed in which the textile is treated with an aqueous solution containing 1%-35% by weight of zirconyl acetate, 0.3%-35% of acetic acid and 1%-25% of an inorganic peroxide, followed by heat drying of the textile to convert the water-soluble agents to insoluble peroxide complexes of zirconyl acetate. As the inorganic peroxides required for this one-bath treating process, hydrogen peroxide and alkali metal perborates are suitable and effective. Alternatively, the cellulosic textile may be treated with a 1%-40% solution of zirconyl acetate in water, followed by heat drying of the textile and subsequent treatment with a 1%-30% aqueous solution of an inorganic peroxide, followed by heat drying of the textile. Inorganic peroxides which are suitable for this two-bath treating process are hydrogen peroxide, alkali metal perborates, and alkali metal peroxydiphosphates. These new treatments inhibit the growth and spreading of odor- and infection- producing bacteria on cellulosic textiles, and the antibacterial activity imparted to the textile is durable to repeated laundering.
