A topsheet 10 for an absorbent article comprising a first fiber layer 1 disposed on the side of a wearer and a second fiber layer 2 disposed on the side of an absorbent member, the first fiber layer 1 and the second fiber layer 2 being partially bonded together at joints 3 in a prescribed pattern, the first fiber layer 1 having protrusions 4 on the wearer's side in portions other than the joints 3, and the second fiber layer 2 being a fiber aggregate containing heat shrinkable fiber and having heat shrunken parts 5 that have shrunken and densified parts 6 that have been inhibited from heat shrinkage.
A topsheet for an absorbent article comprising a first fiber layer disposed on the side of a wearer and a second fiber layer disposed on the side of an absorbent member, said first fiber layer and said second fiber layer being partially bonded together at joints in a prescribed pattern, said first fiber layer having protrusions on the side of a wearer in portions other than the joints, and said second fiber layer being a fiber aggregate containing a heat shrinkable fiber and having heat shrunken parts that have shrunken and densified parts that have been inhibited from heat shrinkage.
A process of producing a topsheet for an absorbent article comprising a first fiber layer disposed on the side of a wearer and a second fiber layer disposed on the side of an absorbent member, said first fiber layer and said second fiber layer being partially bonded together at joints in a prescribed pattern, said first fiber layer having protrusions on the side of a wearer in portions other than the joints, and said second fiber layer being a fiber aggregate containing a heat shrinkable fiber and having heat shrunken parts that have shrunken and densified parts that have been inhibited from heat shrinkage, the process comprising heat embossing a fiber aggregate containing the heat shrinkable fiber to form a second fiber layer-forming material having densified parts, superposing a fiber aggregate as a first fiber layer-forming material on one side of said second fiber layer-forming material, partially bonding together said first fiber layer-forming material and said second fiber layer-forming material, and shrinking said second fiber layer-forming material by heat treatment.
