Absorbent core for disposable absorbent article

A method of making an absorbent core for use in an absorbent article, said method comprising the steps of:

• a. providing a first airlaid absorbent fibrous web material;
• b. providing a second airlaid absorbent fibrous web material, the first and second airlaid absorbent fibrous web materials, if combined into a web prior to deforming portions of the first and second airlaid absorbent fibrous web materials, forming a combined web having an initial permeability and an initial capillary pressure;
• c. providing a pair of rolls forming a nip through which said first and second absorbent fibrous web materials can be processed, said pair of rolls being selected from the processes consisting of, ring rolling, SELF, micro-SELF, and rotary knife aperturing;
• d. deforming portions of said first airlaid absorbent fibrous web by processing through said pair of rolls;
• e. deforming portions of said second airlaid absorbent fibrous web material by processing through said pair of rolls;
• f. after deforming each of the first and second airlaid absorbent fibrous web materials, combining said first and second deformed absorbent fibrous web materials to form said absorbent core, the absorbent core having a permeability higher than the initial permeability and a capillary pressure substantially equal to the initial capillary pressure.

A method of making an absorbent article, said method comprising the steps of:

• a. providing a topsheet material;
• b. providing a backsheet material;
• c. providing a first absorbent fibrous web material;
• d. providing a second absorbent fibrous web material, the first and second absorbent fibrous web materials, if combined into a web prior to deforming each of the first and second absorbent fibrous web materials, forming a combined web having an initial permeability and an initial capillary pressure;
• e. providing a pair of rolls forming a nip through which said first and second absorbent fibrous web materials can be processed, said pair of rolls being selected from the processes consisting of, ring rolling, SELF, micro-SELF, and rotary knife aperturing;
• f. deforming portions of said first absorbent fibrous web material by processing through said pair of rolls;
• g. deforming portions of said second absorbent fibrous web material by processing through said pair of rolls;
• h. after deforming each of the first and second absorbent fibrous web materials, combining said first and second deformed absorbent fibrous web materials in a layered relationship to form a 2-layer absorbent core, the 2-layer absorbent core having a permeability higher than the initial permeability and a capillary pressure substantially equal to the initial capillary pressure;
• and
• i. placing said 2-layer absorbent core between said topsheet and said backsheet and joining said layers in a layered relationship to form said absorbent article.
