  • Absorbent article and wearable article including absorbent article
    Patent number: 10646384
    Abstract: As absorbent article for absorbing urine includes a topsheet which is a nonwoven fabric that has a skin-side surface having projections formed thereon. The content by percentage of fibers oriented in the thickness direction in each projection of the nonwoven fabric is greater than the content by percentage of fibers oriented in the thickness direction in sections of the nonwoven fabric other than the projections. The thickness of the nonwoven fabric when wet is greater than or equal to 85% the thickness of the nonwoven fabric when dry. The nonwoven fabric includes a first fiber layer and a second fiber layer. The first fiber layer is constituted by durable hydrophilic fibers, and the second fiber layer is constituted by durable hydrophilic fibers and non-durable hydrophilic fibers.
