Absorbent article including nonwoven sheet for absorbent body, and method for producing nonwoven sheet used for absorbent article

摘要

The present invention provides: an absorbent article containing a non-woven fabric sheet for an absorbent, wherein the non-woven fabric sheet is produced without employing a strength-imparting means such as post-coating of an adhesive agent that can deteriorate a liquid diffusion property of the non-woven fabric sheet and therefore the non-woven fabric sheet has an excellent liquid diffusion property; and a method for producing the non-woven fabric sheet that can be used in the absorbent article. The absorbent article (1) according to the present invention comprises a liquid-permeable surface sheet (2), a liquid-impermeable back sheet (3), an absorbent (4) arranged between the surface sheet (2) and the back sheet (3), and a non-woven fabric sheet (8) for the absorbent (4), wherein the non-woven fabric sheet (8) contains pulp and comprises a pulp fiber layer (81) having a first surface and a second surface, a first-surface-side fiber layer (82) which is arranged on the first surface side of the pulp fiber layer (81) and is mainly composed of hydrophilic fibers having an average fiber length of 25 to 64 mm, and a second-surface-side fiber layer (83) which is arranged on the second surface side of the pulp fiber layer (81) and is mainly composed of hydrophilic fibers having an average fiber length of 25 to 64 mm.
