Abstract
A nonwoven web material of polymeric fibers having at least one internal surfactant and at least one topical surfactant. The internal surfactant is an organosilicon compound. The topical surfactant is at least one of an ethoxylated hydrogenated fatty oil, a monosaccharide, a monosaccharide derivative, a polysaccharide, and a polysaccharide derivative. The nonwoven web material treated with internal and external surfactants has improved durability and processability over conventional materials treated with only internal or topical surfactants.
