Abstract: A method of durably rendering a polymeric fabric, e.g., a polyolefin fabric, wettable and resistant to protein adsorption. The method involves providing a polymeric fabric having a surface, applying to the surface of the polymeric fabric a composition which includes water and a surfactant adapted to durably render the polymeric fabric resistant to protein adsorption, and drying the polymeric fabric. The surfactant has a solubility in water at 20.degree. C. no greater than about 5 percent by weight, based on the weight of the water, and is present on the polymeric fabric in an amount of the surfactant sufficient to reduce the adsorption of the protein by the fabric. The coated fabric not only exhibits durable reduced adsorption of protein but also has durable wettability by aqueous liquids.

Abstract: A method of reducing the adsorption of protein by a polymeric fabric; e.g., a polyolefin fabric, which involves providing a polymeric fabric having a surface, applying to the surface of the polymeric fabric a composition including water and a surfactant adapted to reduce the adsorption of protein by the polymeric fabric, and treating the fabric to which a surfactant has been applied by air corona discharge at a corona energy density of from about 10 to about 280 kilojoules per square meter. The surfactant is present on the fabric in an amount sufficient to reduce the adsorption of protein by the fabric. The coated fabric is especially suited for incorporation in such disposable absorbent articles as diapers; feminine care products, such as sanitary napkins and tampons; incontinent care products; training pants; and wipes.

Abstract: A high surface area oxidative catalyst smoke suppressive composition, smoke suppressive articles, and method of making such compositions and articles are disclosed. The smoke suppressive composition is a solid solution comprising a mixture of iron (Fe) and magnesium (Mg) that promotes efficient combustion, articles treated with such compositions, and methods for making such smoke suppressive compositions and articles. The smoke suppressive composition is made by co-precipitating Fe and Mg from an aqueous solution in the presence of a base. The iron-magnesium composition demonstrates high surface area and efficient combustion for embodiments having iron in an amount from approximately 3 mol % to approximately 30 mol % and magnesium in an amount from approximately 97 mol % to approximately 70 mol %. The compositions provide superior smoke suppression for items such as cigarettes and smoke suppressive articles.
