PCT No. PCT/US95/08379 Sec. 371 Date Jan. 6, 1997 Sec. 102(e) Date Jan. 6, 1997 PCT Filed Jul. 3, 1995 PCT Pub. No. WO96/01657 PCT Pub. Date Jan. 25, 1996The invention relates to an absorbent gelling material comprising a dry mixture of at least a first type of hydrogel-forming particles and a second type of hydrogel-forming particles. The absorbent gelling material in accordance with the invention is characterized in that the first type of hydrogel-forming particles has an Absorption Against Pressure value which is higher than the Absorption Against Pressure value of the second type of hydrogel-forming particles, the weight of the second type of hydrogel-forming particles forming at least 10% of the combined weight of the first and second type of hydrogel forming particles. The invention also relates to a method for making such material. |
