Abstract
The blood absorbence properties, e.g., free swell blood absorbence capacity and after load blood absorbence capacity of superabsorbent materials is enhanced by combining the superabsorbent materials with enhancing agents which serve to enhance the blood absorbent properties thereof. The enhancing agents can be applied to the superabsorbent materials or they can be provided on a fibrous material to be combined with the superabsorbent materials. The enhancing agents are selected from materials that include functionalities that allow them to hydrogen bond to the superabsorbent material when the enhancing agent is applied directly thereto or combined with materials to which the enhancing agents have been applied.
Claims25
A method for enhancing the blood absorbence properties of superabsorbent material having a hydrogen bond forming functionality comprising the steps:
- selecting an enhancing agent from the group consisting of non-polymeric organic enhancing agents and combinations thereof nonreactive with each other, the enhancing agents comprising enhancing agent molecules, the enhancing agent molecules having at least one functional group capable of forming a hydrogen bond with the superabsorbent material;
- and
- applying the enhancing agent in liquid or solution form onto the superabsorbent material, the enhancing agent being present on the superabsorbent material in an amount ranging from about 0.01 to about 10 percent of the weight of the superabsorbent material.
