The preparation of bacteriostatic, water-insoluble peroxide-containing complexes of zinc acetate by reaction, of zinc acetate with hydrogen peroxide in the presence of acetic acid, is disclosed. A process for in situ formation and deposition of these complexes on cellulosic and polyester textiles is described. The textile finishes so produced inhibit the growth and spreading of odor- and infectionproducing gram-positive and gram-negative bacteria on the treated textiles. The antibacterial activity of the finished textiles is durable to repeated launderings.
