(57) Abstract:
(EN): This absorbent article 100 is provided with an absorbent body 10. The absorbent body 10 contains water-absorbent resin particles 10a, the water-absorbent resin particles 10a have a packed bulk density of 0.500 g/cm3 or more, and the amount of change in the packed bulk density when moisture is absorbed for one hour at a temperature of 30ºC and a relative humidity of 80% is 0.020 g/cm3 or more.
(FR): Selon l'invention, un article absorbant (100) de l'invention est équipé d'un corps absorbant (10). Le corps absorbant (10) comprend des particules de résine absorbantes (10a). Dans les particules de résine absorbantes (10a), la densité apparente compactée est supérieure ou égale à 0,500g/cm, et la quantité de variation de la densité apparente compactée après absorption de l'humidité pendant une heure à une température de 30°C et une humidité relative de 80%, est supérieure ou égale à 0,020g/cm.
(JA): 吸収性物品100は、吸収体10を備え、吸収体10は、吸水性樹脂粒子10aを含有し、吸水性樹脂粒子10aにおいて、固めかさ密度が0.500g/cm3以上であり、温度30℃、相対湿度80%で1時間吸湿させたときの固めかさ密度の変化量が0.020g/cm3以上である。
