ABSORBENT ARTICLE

摘要

The present invention addresses the problem of, in an absorbent article, maintaining at a certain level or lower the difference between the dry flexural rigidity and wet flexural rigidity [(dry flexural rigidity)−(wet flexural rigidity)] at a bonding part. To solve this problem, provided is a sanitary napkin which comprises a top sheet, a back sheet, an absorbent body that is interposed between the top sheet and the back sheet and a compressed part that unites the top sheet and the absorbent body in the thickness direction, wherein: the absorbent body contains a cellulose-based water absorbing fiber and a thermoplastic resin fiber, said thermoplastic resin fiber containing as a monomer component an unsaturated carboxylic acid, an unsaturated carboxylic acid anhydride or a mixture thereof; and the difference between the dry Gurley stiffness and wet Gurley stiffness of the compressed part is maintained at 2.5 mN/12.5 mm or lower.

1. An absorbent article comprising a liquid-permeable layer, a liquid-impermeable layer, an absorbent body provided between the liquid-permeable layer and the liquid-impermeable layer, and a joining section that joins the liquid-permeable layer and the absorbent body,
wherein the absorbent body contains, as constituent fibers, cellulose-based water-absorbent fibers, and thermoplastic resin fibers that include an unsaturated carboxylic acid, an unsaturated carboxylic anhydride or a mixture thereof as the monomer component, and the difference between the dry Gurley bending resistance and the wet Gurley bending resistance of the joining section is 2.5 mN/12.5 mm or less.
