ABSTRACT:
A non-woven fabric treated with a biocidal composition including at least one halogenated phenolic biocide; a water soluble, film forming polymer which is a polyvinylpyrrolidone polymer or copolymer; and at least one surfactant, wherein a complex is formed between the halogenated phenolic biocide and the polyvinylpyrrolidone polymer or copolymer so that, after treatment of the non-woven fabric therewith and drying, no cloudy residue remains on the non-woven fabric. A method of impregnating a fabric to prevent rot includes contacting a non-woven fabric with a liquid biocidal composition containing at least one halogenated phenolic biocide, a water soluble, film forming polymer, which is a polyvinylpyrrolidone polymer or copolymer; and at least one surfactant, wherein a complex is formed between the halogenated phenolic biocide and the polyvinylpyrrolidone polymer or copolymer so that, after contacting the non-woven fabric with the liquid biocidal composition and drying, no cloudy residue remains on the non-woven fabric.
