Patent ID: 7175910

Claim:
An absorbent core for collection of bodily liquids, such as urine, said core comprising: a super absorbent gelling material, said super absorbent gelling material being in the form of particles, wherein: said particles have a longest and a smallest dimension with a particulate ratio of longest to smallest particle dimension in the range of 1–5; said particles are provided with a surface cross-linking in order to provide said particles with an individual particle stability such that said AGM super absorbent gelling material has a measured SFC of at least 30 units; said particles further have a substantially non-covalently bonded surface coating with a partially hydrolysable cationic polymer, such that said super absorbent gelling material has a measured BBS of more than 80 grams of force after 30 minutes and a BBS after 16 hours of at least 50% of the BBS after 30 minutes; said coating is present on said particles in an amount of less than 10% by weight of said particles; and said super absorbent gelling material is present in said core in a concentration of 60% by weight or more.
