  • Patent number: 6635799
    Abstract: A body-contacting surface or topsheet for absorbent articles or devices that is comfortable when it is placed in contact with hydrous body tissues is disclosed. In one non-limiting embodiment, the topsheet is a non-absorbent, moderately hydrophilic to substantially hydrophobic nonwoven web. The topsheet can have a critical surface tension of less than or equal to about 45 dynes/cm. In one embodiment, the nonwoven web has been mechanically modified so that it is extensible in an amount greater than equal to about 30% under a force of 50 grams, and undergoes a caliper change of greater than or equal to about 30% under a pressure of 1,000 Pa after being subjected to a pressure of 250 Pa. The topsheet is placed on absorbent devices such as sanitary napkins, tampons, pantiliners, interlabial devices, incontinence devices, bandages, and other types of articles.

  • Patent number: 6103952
    Abstract: An absorbent article especially adapted for users ranging from walking infants to adults in a predominantly laying-down position includes a layer of absorbent material, wherein the average basis capacity of absorbent material located in a back half section of the layer is higher than the average basis capacity of absorbent material located in the front half section of the layer. A liquid barrier means is located between a transverse centerline of the layer and the waist edge of a back sheet to prevent liquids from leaking to the back waist edge.
