Abstract
There is disclosed an absorbent article including an absorbent layer and a liquid-permeable surface sheet placed on a liquid-receiving side of the absorbent layer for introducing excreted liquid from the human body to the absorbent layer. The surface sheet is of a corrugated configuration to have valleys and peaks extending in a longitudinal direction of the article and alternately arranged in a transverse direction perpendicular to the longitudinal direction. Each valley has a connecting part raised to connect between two adjacent peaks.

An absorbent article comprising an absorbent layer and a liquid-permeable surface sheet placed on a liquid-receiving side of the absorbent layer for introducing excreted liquid from the human body to the absorbent layer, wherein
- the surface sheet is of a corrugated configuration to have valleys and peaks extending in a longitudinal direction of the article and alternately arranged in a transverse direction perpendicular to the longitudinal direction, and wherein
- each valley has a connecting part raised to connect between two adjacent peaks.
A process for manufacturing an absorbent article, comprising the steps of:
- (a) pressing a nonwoven fabric, which is supplied in a predetermined direction, between a first shaping means and a second shaping means to form a surface sheet, and
- (b) placing and fixing the surface sheet on a liquid-receiving side of an absorbent layer, wherein
- the first shaping means has ribs and grooves extending in the supplying direction of nonwoven fabric and alternately arranged in a transverse direction perpendicular to the supplying direction;
- the second shaping means has ribs and grooves extending in the supplying direction and alternately arranged in the transverse direction, each rib of which has a plurality of recesses formed at intervals in the supplying direction;
- and
- the surface sheet formed in the step (a) has peaks each compressed between the rib of the first shaping means and the groove of the second shaping means, valleys each compressed between the groove of the first shaping means and the rib of the second shaping means, and connecting parts raised from the valleys to connect between two adjacent peaks at the part corresponding to the recesses of the second shaping means.
