A topsheet for absorbent articles having absorbing performance for smoothly transferring liquid body waste, e.g., menstrual blood or urine, to an underlying absorbent member and surface characteristics such that the surface thereof in contact with wearer's skin is soft enough not to cause skin irritation. The topsheetcomprises a first layerdisposed on the side of a wearer and a second layerdisposed on the side of an absorbent member, the first layer and the second layer being partly joined together, and having protrusions and depressions on the side of a wearer, wherein the first and second layers each comprise a fiber aggregate, the first layer has fusion-bonded fiber intersections, the first layer has an apparent thickness (t) of 0.1 to 5 mm, the second layer has an apparent thickness (t) of 0.2 to 3 mm, the apparent thickness ratio of the first layer to the second layer (t/t) is 0.5 to 8, the first layer has a fiber density (d) of 0.001 to 0.05 g/cm, the second layer has a fiber density (d) of 0.03 to 0.2 g/cm, and the fiber density (d) of the second layer is higher than that (d) of the first layer.

Topsheet for absorbent article

A topsheet for absorbent articles is disclosed. The topsheet is used on the side of an absorbent article to be brought into contact with a wearer's body. The topsheet has an air permeability of 10 ml/cm&#xb7;sec or more in the horizontal direction under a pressure of 10 cN/cm. The topsheet also has an air permeability of 10 to 500 ml/cm&#xb7;sec in the horizontal direction under a pressure of 50 cN/cm.

A topsheet for an absorbent article which has an uneven profile formed on a surface thereof to be brought into contact with a wearer's skin, the uneven profile being flexibly deformable in conformity to the contour of the wearer's body and to the wearer's movement, and depressions of the uneven profile being capable of trapping high-viscosity excreta thereby separating the high-viscosity excreta from the wearer's skin while an absorbent article having the topsheet is worn.

A topsheetfor an absorbent article comprising a first fiber layerdisposed on the side of a wearer and a second fiber layerdisposed on the side of an absorbent member, the first fiber layerand the second fiber layerbeing partially bonded together at jointsin a prescribed pattern, the first fiber layerhaving protrusionson the wearer's side in portions other than the joints, and the second fiber layerbeing a fiber aggregate containing heat shrinkable fiber and having heat shrunken partsthat have shrunken and densified partsthat have been inhibited from heat shrinkage.
