摘要： Disclosed is an absorbent composition comprising each of an acidic and a basic material, wherein the absorbent composition exhibits desirable absorbent properties. Specifically, the present invention relates to an absorbent composition comprising either an acidic water-swellable, water-insoluble polymer having a pKa between about 2 to about 12 or a basic water-swellable, water-insoluble polymer having a pKb between about 2 to about 12 and either a basic or an acidic second material. The absorbent composition has the ability to slowly absorb a large quantity of liquid, particularly while under an external pressure. The absorbent composition is useful in disposable absorbent products, such as those disposable absorbent products that are used to absorb bodily liquids.

摘要： A stretchable absorbent composite having a Composite Permeability of about 10 Darcy or more, or about 15 Darcy or more, and Composite Stretchability of about 30% or more, or about 50% or more, or about 100% or more, and a method of making such a stretchable absorbent composite. The stretchable absorbent composite includes a superabsorbent material, an elastomeric material, and, optionally, pulp fibers. More particularly, the stretchable absorbent composite may include between about 30% and about 85% by weight superabsorbent material, between about 5% and about 25% by weight elastomeric material, and between about 10% and about 70% by weight pulp fibers.

摘要： Superabsorbent material treated to resist damage when subjected to an Absorbent Product Processing Simulation Test, which simulates the mechanical damage that occurs during current commercial diaper manufacturing processes. The treated superabsorbent material has a centrifuge retention capacity of about 15 grams or greater of 0.9 weight percent sodium chloride per gram of the superabsorbent material and a gel bed permeability (GBP) at 0 psi swell pressure on pre-screened particles of about 200 (×10−9 cm2) or greater. After subjecting the treated superabsorbent material to the Absorbent Product Processing Simulation Test, the treated superabsorbent may exhibit minimal reduction in GBP of pre-screened or un-screened particles at 0 psi or at 0.3 psi swell pressure, as well as possibly exhibiting minimal reduction in average particle size diameter (PSD). The superabsorbent material can be treated by adding an aqueous solution of a hydrophilic soft polymer to the superabsorbent material, mixing the superabsorbent material with the aqueous solution, and drying the superabsorbent material.

摘要： 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.

摘要： Certain antimicrobial agents, particularly chitosan- or chitin-based polymers, exhibit increased antimicrobial activity when coated onto the surface of a hydrophobic material such as polypropylene. When applied to the surface of a polypropylene nonwoven fabric, for example, the resulting material can be used for diaper liners to reduce odors and promote skin wellness.
