摘要： An absorbent article contains a non-woven fabric sheet for an absorbent. 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. The absorbent article includes a liquid-permeable surface sheet, a liquid-impermeable back sheet, an absorbent arranged therebetween, and the non-woven fabric sheet for the absorbent. The non-woven fabric sheet contains pulp, a pulp fiber layer, a first-surface-side fiber layer arranged on a first surface of the pulp fiber layer and mainly composed of hydrophilic fibers having an average fiber length of 25 to 64 mm, and a second-surface-side fiber layer arranged on a second surface of the pulp fiber layer and mainly composed of hydrophilic fibers having an average fiber length of 25 to 64 mm.

摘要： An absorbent body for an absorbent article includes: an absorbent core comprising a polymer absorbing agent; and core wraps. The core wraps include: (i) a first hydrophilic fiber-containing layer that is adjacent to the absorbent core and contains first hydrophilic fibers having an average fiber length of 25 mm to 75 mm; (ii) a pulp fiber-containing layer that is adjacent to the first hydrophilic fiber-containing layer and contains pulp fibers and (iii) a second hydrophilic fiber-containing layer that is adjacent to the pulp fiber-containing layer and contains second hydrophilic fibers having an average fiber length of 25 mm to 75 mm. Some of the pulp fibers pass through the first hydrophilic fiber-containing layer and are in contact with the absorbent core.
