摘要: A through-air bonded nonwoven fabric comprises a first surface and a second surface and a visually discernible pattern of three-dimensional features on one of the first or second surfaces. Each of the three-dimensional features define a microzone comprising a first region and a second region. The first and second regions have a difference in values for an intensive property, wherein in at least one of the microzones, the first region exhibits a Contact Angle of greater than 90 degrees, as measured by the Contact Angle Test Method, and wherein the second region exhibits a Time to Wick of less than 10 seconds, as measured by the Time to Wick Test Method.

摘要: A nonwoven fabric. The nonwoven fabric can include a first surface and a second surface and a visually discernible pattern of three-dimensional features on one of the first or second surface. Each of the three-dimensional features can define a microzone comprising a first region and a second region. The first and second regions can have a difference in values for an intensive property, and wherein in at least one of the microzones, the first region is hydrophobic and the second region is hydrophilic.

摘要: A web having a first surface and a second surface, a plurality of apertures extending through the web from the first surface to the second surface, wherein at least a portion of the plurality of apertures are treated with a composition and at least a portion of the apertures are untreated is disclosed. The treated apertures form a plurality of treated aperture zones, and the untreated apertures form a plurality of untreated aperture zones. Each of the plurality of treated aperture zones has one or more apertures, and each of the plurality of untreated aperture zones has one or more apertures. The plurality of treated aperture zones includes between about 25 percent to about 75 percent of the plurality of apertures.

摘要: An absorbent article having a longitudinal centerline, a lateral centerline, a machine direction (MD) generally oriented parallel to the longitudinal centerline and a cross direction (CD) generally oriented parallel to the lateral centerline is described. The absorbent article includes a topsheet, a backsheet, and an absorbent core disposed therebetween. A plurality of composition elements is disposed on the topsheet, wherein each of the composition elements comprise an element width and an element spacing between adjacent elements, and wherein a ratio of element spacing to element width is between about 0.5 to about 8, as measured by the Composition Pattern Analysis.
