Abstract
The absorbent in accordance with the present invention is limited in at least two of the following requirements: ventilation resistance, absorbency under no load and/or under load, weight mean particle diameter, and water-soluble components. The absorbent exhibits a 24 g/g or more absorbency under a 2.0 kPa load and a 50 kPa·sec/m or less ventilation resistance under a 4.9 kPa load in a wet state. The absorbing product in accordance with the present invention is based on this absorbent and therefore exhibits improved ventilating properties when worn and relatively little wet back of water-based liquids, providing a further improved sense of comfort to users wearing the absorbing product.
