Abstract of the Disclosure A polymeric fabric having enhanced wettability, a method for producing such wettable polymeric fabric. and a composition for use in the method. The polymeric fabric is preferably a nonwoven. In one embodiment, the fabric includes a sorbitol succinate surfactant substantially uniformly distributed on the surface of the fabric. The sorbitol succinate surfactant is applied with a co-wetting aid which reduces the surface tension of the surfactant composition. In another embodiment, the polymeric fabric comprises multiple surfactants on the surface of the polymeric fabric. The first surfactant has a cloud point less than 50°C and a low solubility in water and is dispersible in water. The second surfactant comprises a sorbitol succinate surfactant. The first and second surfactants are applied to the fabric in an aqueous solution preferably with a co-wetting aid such as a primary or secondary alcohol. The co-wetting aid wets the polymeric fabric with the composition during application of the composition to the polymeric fabric and then evaporates.
