The fibrous nonwoven web is made from a plurality of fibers heat bonded to one another to form a nonwoven web having a basis weight of at least 20 grams per square meter, a void volume of between about 40 and about 60 centimeters per gram of web while under a pressure of 689 dynes per square centimeter, a permeability of about 5,000 to about 8,000 darcy, a porosity of about 97.2 percent to about 98.8 percent and a surface area per void of about 24 to about 49 square centimeters per cubic centimeter. The fibrous nonwoven web will have a saturation capacity of between about 30 and about 50 grams of 0.9 percent saline solution per gram of web and a compression resilience in both the wet and dry state of at least about 60 percent.
