A personal care absorbent article, such as a sanitary pad or napkin, wound dressing, and the like having an absorbent material treated with a fluid treatment agent, which fluid treatment agent causes red blood cells in a blood-containing fluid to agglomerate or lyse as the fluid passes into and/or through the absorbent article. In accordance with one preferred embodiment, the absorbent material is a porous nonwoven web material.

Absorbent article with fluid treatment agent

There is provided an intake/retention/transfer material for personal care products like feminine hygiene products, which is a heterogeneous composite containing between 5 and 25 weight percent of a superabsorbent or gelling material and having a density less than 0.17 g/cc. A more particular embodiment contains less than 20 weight percent and a still more particular embodiment contains 15 weight percent or less of a superabsorbent or gelling material. Also provided are absorbent articles which contain the class of intake/transfer materials mentioned above along with additional absorbent layers such that the absorption of a menses simulant provides fluid partitioning of less than 72% of fluid in the intake/transfer/retention composite. Additionally said composite should have retention capacity values greater than 2.7 g/g.

Personal care product with fluid partitioning

A wet-formed composite defining latent voids and macro-cavities, the wet-formed composite having a basis weight greater than about 100 grams per square meter and a density of about 0.06 grams per cubic centimeter or more. The wet-formed composite comprises fibers and superabsorbent material, with the superabsorbent material present in an amount of about 10 dry weight percent or less, specifically about 5 dry weight percent or less, and particularly about 2 dry weight percent or less, but more than 0, based on the total dry weight of fibers and superabsorbent material present in the wet-formed composite. By virtue of the superabsorbent material having been allowed to swell and then shrink during the making of the wet-formed composite, macro-cavities are created. Densification compresses the macro-cavities. The resulting composite expands upon wetting and exhibits good absorbency properties.

An absorbent article includes a vapor permeable backsheet, a liquid permeable topsheet positioned in facing relation with the backsheet; and an absorbent body located between the backsheet and the topsheet. The absorbent body may include multiple zones of high air permeability or may include materials which provide improved air exchange after being wetted. The absorbent article may also include a ventilation layer between the absorbent body and the backsheet and a surge management layer between the absorbent body and the topsheet. The article exhibits improved air exchange within the article during use. As a result, the article exhibits substantially reduced levels of hydration of the wearer's skin when in use which renders the skin less susceptible to the viability of microorganisms.
