Abstract
The present invention relates to a three-dimensional nonwoven comprising a first side, a second side, a protruded first area comprising an upper portion formed in the first side and a lower portion formed in the second side, and a second area comprising a plurality of deformations, wherein the upper portion has a shape memory index higher than a shape memory index of the lower portion, an absorbent article comprising the three-dimensional nonwoven, and a process for producing the three-dimensional nonwoven.
Claims21
An absorbent article comprising a skin-facing surface, a garment-facing surface, a liquid permeable topsheet, a liquid impermeable backsheet, an absorbent structure disposed between the topsheet and the backsheet, and a three-dimensional nonwoven,
- wherein the three-dimensional nonwoven comprises:

- wherein an edge to edge space is no greater than about 3 mm between the at least one deformation and each of the at least three adjacent deformations,
- wherein the upper portion comprises an upper portion height,
- wherein the lower portion comprises a lower portion height,
- wherein the lower portion height is less than the upper portion height as measured according to Height Test,
- wherein a shape memory index of the upper portion is higher than a shape memory index of the lower portion, and
- wherein the first area is filled with fibers.
