Abstract

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 topsheet 1 comprises a first layer 11 disposed on the side of a wearer and a second layer 12 disposed 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 (t1) of 0.1 to 5 mm, the second layer has an apparent thickness (t2) of 0.2 to 3 mm, the apparent thickness ratio of the first layer to the second layer (t1 / t2) is 0.5 to 8, the first layer has a fiber density (d1) of 0.001 to 0.05 g / cm<3>, the second layer has a fiber density (d2) of 0.03 to 0.2 g / cm<3>, and the fiber density (d2) of the second layer is higher than that (d1) of the first layer.

Description

technical field

[0001] The present invention relates to absorbent articles, such as sanitary napkins, panty liners, incontinence pads and disposable diapers, and to sheets for absorbent articles as topsheets that contact the wearer's body. Background technique

[0002] Topsheets for absorbent articles, such as sanitary napkins, are required not only to have absorbent properties that allow smooth transfer of liquid body waste, such as menstrual blood or urine, to the underlying absorbent member, but also to have a surface that is compatible with the wearer's skin. The contact surface is soft enough not to irritate the skin.

[0003] Top sheets of absorbent articles currently used include nonwoven fabrics produced by various methods, porous nonwoven fabrics, and porous films of synthetic resins such as polyethylene, but none of them can sufficiently satisfy the above-mentioned requirements. Requirements for absorbent properties and surface properties. ...
