Abstract
An absorbent article having a compressed region formed by a compressing process in an absorption layer on a side facing to the backsheet; and a plurality of pressed grooves are formed by a pressing process in the absorption layer on a side facing to the topsheet, within a region opposed to the compressed region.
Claims6
An absorbent article comprising:
- a liquid-permeable topsheet;
- a liquid-impermeable backsheet;
- and
- an absorption layer arranged between the topsheet and the backsheet, wherein:
- a compressed region is formed by a compressing process in the absorption layer on a side facing to the backsheet;
- a plurality of pressed grooves are formed by a pressing process in the absorption layer on a side facing to the topsheet, within a region opposed to the compressed region;
- a bottom face of the compressed region is formed so as to be closer to the topsheet near outer edges of the compressed region;
- and
- a fiber density of the absorption layer increases near said outer edges of the compressed region.

A method of manufacturing an absorbent article including a liquid-permeable topsheet, a liquid-impermeable backsheet, and an absorption layer arranged between the topsheet and the backsheet, the method comprising:
- a step of forming a compressed region in the absorption layer by performing a compressing process to the absorbent article from a side facing to the backsheet;
- and
- a step of forming a plurality of pressed grooves within a region opposed to the compressed region in the absorption layer, by performing a pressing process to the absorbent article from a side facing to the topsheet, wherein
- a bottom face of the compressed region is formed so as to be closer to the topsheet near outer edges of the compressed region;
- and
- a fiber density of the absorption layer increases near said outer edge of the compressed region.
