Abstract
A method for forming a fibrous three dimensional structure comprises providing a first fibrous layer, wherein the first fibrous layer is aligned in the machine direction. At least one additional fibrous layer is superposed with the first fibrous layer, wherein the direction of alignment of the at least one additional fibrous layer is at an acute angle to the machine direction. The first fibrous layer and the at least one additional fibrous layer are needled together at a needle density of greater than approximately 55 needle punches per square centimeter, forming a first combined fibrous mat. The combined fibrous mat is superposed with at least one additional combined fibrous mat and needled at a needle density of less than approximately 60 needle punches per square centimeter, forming a fibrous three dimensional structure.
