Filed:

Oct 30, 1998

Appl. No.:

09/183170

Assignee:

Kimberly-Clark Worldwide, Inc. - Neenah WI

International Classification:

B32B 2704

US Classification:

442123, 442 59

Abstract:

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.

International Classification:

B29B 904

US Classification:

264113, 264115

Abstract:

A method of incorporating a density modulator into an absorbent composite includes the steps of applying a density modulator solution to a pulp sheet, fiberizing the pulp sheet, and incorporating the fiberized pulp sheet into an absorbent composite. The density modulator can be applied by slot coating or by using a flooded nip. Once the density modulator is incorporated into the absorbent composite, the absorbent composite is highly wettable and, upon contact with blood-containing bodily fluids, undergoes a decrease in density, thereby increasing the absorbent capacity of the absorbent composite.

Abstract:

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.

International Classification:

A61F013/15

US Classification:

604367, 442121, 442123, 442327, 442381, 442417, 502400, 502405, 502526

Abstract:

A personal care absorbent article, such as a sanitary pad or napkin, wound dressing, and the like having one or more layers of absorbent material treated with a red blood cell lysing agent and a gelling agent. The effect of combining a lysing agent that thins menses or other blood-containing bodily fluids with a gelling agent that thickens menses or other blood-containing bodily fluids is enhanced agglomeration and increased viscosity of the blood-containing bodily fluids that come in contact with the treated material.

Abstract:

The present disclosure relates to personal care products such as diapers, training pants, feminine care articles, incontinence articles, bandages, and the like, that have been treated to enhance liquid intake and distribution performance characteristics and reduce leakage. Advantageously, the treated personal care products described herein not only reduce the viscosity and elasticity of viscoelastic fluids that come in contact with the treated product, but also reduce the fouling effect of such fluids.

International Classification:

B32B003/00

US Classification:

428/195100

Abstract:

A striped material and a stripe focusing plate for making striped material. The stripe focusing plate includes a number of grooves extending through the plate, each groove having a transverse width l. The stripe focusing plate also includes a number of triangular prisms, each adjacent a groove and having a slope between about 70 and about 85 degrees. Particles distributed onto the plate fall through the grooves onto a substrate positioned below the plate to form stripes on the substrate. Each of the stripes has a half-height width L, and a sharpness coefficient L/l of less than 1. The resulting striped material is particularly suitable for use in disposable absorbent articles.
