Abstract

1449239 Coated products MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 6 Nov 1973 [9 Nov 1972 (3) 14 Feb 1973] 51518/73 Heading B2E [Also in Division C1] A bactericidal membrane for a water purifier comprises a porous sheet of a water-insoluble non-woven cloth having coatings of a silver halide formed such that the surface of each fibre of the cloth in a surface layer on each side of the sheet is covered with the halide. The product may be obtained by immersing the sheet in an aqueous solution of a water-soluble silver salt, immersing the sheet further in an aqueous solution of a halide to convert the silver salt into the silver halide, washing the coated and impregnated sheet and drying. Alternatively the coatings may be formed by immersing the sheet in aqueous ammonia containing silver chloride as the ammine complex and drying. The preferred halide is the chloride. The substrate may be a canvas, non-woven cloth, asbestos cloth, glass fibre cloth and Japanese paper. A preferred non-woven cloth is formed from a synthetic fibre such as nylon, rayon, acetate, polyethylene terephthalate or other polyester, polypropylene, partially acetalformed polyvinyl alcohol and mixtures of these.
