ABSTRACT OF THE DISCLOSURE Nonwoven, hydrophobic fibrous substrates uniformly coated with a wetting agent are disclosed which have improved tensile strength properties over conventional coated, nonwoven substrates. Also disclosed is a process for applying a high solids content wetting agent to a substrate in a manner which results in low wet pick-up and eliminates drying requirements. The low wet pick-up reduces degradation of the tensile strength of the material normally resulting from with the wetting and drying of nonwoven substrates. In one embodiment the untreated side remains hydrophobic producing a "one-way valve" effect.
