Absorbent structures that form superabsorbent polymers in situ. The structures include an absorbent material and a fibrous material containing an activating agent. The fibrous material releases the activating agent upon stimulation with an activator, which causes the polymer to become a superabsorbent polymer. The absorbent component is desirably a water-swellable, water-insoluble polymer. The absorbent structures form a superabsorbent composition in situ. Methods of making the activating agent containing fibrous material are provided.

Methods of making permanently wettable superabsorbent material are provided. The permanently wettable superabsorbent materials made by the method have a floating time less than 30 seconds and cause a reduction in surface tension of saline less than about 30%. The methods involve treating the superabsorbent material with a surfactant solution. A surfactant is used that has at least one functional group that is reactive with the superabsorbent material and at least one non-reactive and hydrophilic functional group. The surfactant is applied to the superabsorbent material when the functional groups on the surface of the superabsorbent material are activated. Permanently wettable superabsorbent materials, such as fibers, made by the method and disposable absorbent products comprising the permanently wettable superabsorbent material are also provided.

The present invention is directed to absorbent composites having enhanced intake properties. The absorbent composites of the present invention have a Composite Permeability (CP) value at full swelling of greater than about 100 ×10cm. Further, the absorbent composites, of the present invention have a Composite Permeability/3Insult Fluid Intake Flowback Evaluation (FIFE) intake relationship, which results in enhanced intake properties. The present invention is also directed to a method of making absorbent composites having enhanced intake properties. The present invention is further directed to absorbent composites and their applicability in disposable personal care products.

Absorbent articles including an absorbent core having multiple absorbent layers. The absorbent layers interact in a manner which desirably locates absorbed liquid in an appointed, high saturation wicking layer. The localization of the liquid within this wicking layer increases the potential of this layer to move liquid through capillary action due to the higher saturation level and increased amount of liquid available. The intake capability of the absorbent system is maintained or improved over current systems by keeping a second layer of the absorbent system at low saturation levels through as many insults of the absorbent article as possible, while providing enhanced intake performance through appropriate control of the composite properties.
