Method for determining and/or visualizing airflow through absorbent cores and absorbent articles exhibiting enhanced airflow

A method for comparing liquid distribution between two or more different absorbent article cores, said method comprising the steps of:

• providing a first absorbent core adapted to be sandwiched between a liquid permeable topsheet and a liquid impermeable backsheet of an absorbent article;
• providing a second absorbent core adapted to be sandwiched between a liquid permeable topsheet and a liquid impermeable backsheet of an absorbent article;
• providing a thermal imaging camera;
• loading the first and second absorbent cores with an equal and predetermined amount of warm liquid, wherein said warm liquid has a temperature of greater than 30° C.;
• visually recording said absorbent core with said thermal imaging camera;
• and
• comparing an image of the first absorbent core with an image of the second absorbent core taken no more than 60 seconds from complete loading of said absorbent cores.
