Abstract
Disclosed herein is a compressively resistant and resilient fibrous nonwoven web which is suitable for a wide variety of uses including, but not limited to, a portion of a personal care absorbent product which is located on the side of the absorbent core of the product which faces the wearer. The nonwoven web can include bicomponent fiber and has a thickness of 2.5 mm or greater at a pressure of 68.9 pascal, a specific volume of 14 cc/g or greater at a pressure of 6,895 pascal, and a Frazier air permeability of 100 cubic meters per square meter per minute or greater.
Claims31
