An absorbent articleincludes an absorber, the absorbercontains water-absorbent resin particlecomposed of a deodorant composition, and the deodorant composition contains silver zeolite, an organic antimicrobial, and a water-absorbent resin.

Deodorizer composition, absorbing body, and absorbent article

Disclosed is a method for improving a water absorption amount under load by water absorbent resin particles, the method including shaking a powder containing a plurality of water absorbent resin particles contained in a container. An amount of powder corresponding to a theoretical filling rate of less than 100% may be contained in the container.

Method for increasing amount of water absorbed under load by water absorbent resin particles, and method for producing water absorbent resin particles

An absorbent articleincludes an absorber, the absorbercontains water-absorbent resin particlecomposed of a deodorant composition, and the deodorant composition contains silver zeolite, a sulfur compound, and a water-absorbent resin.

Deodorant composition, absorbent, and absorbent article

Disclosed is water-absorbent resin particles, in which a value of non-pressurization DW after 3 minutes is 14 ml/g or more, and a value of liquid suction power after 3 minutes measured by the following method is 11 ml/g or more. A liquid suction power measurement method: 0.3 g of the water-absorbent resin particles is uniformly dispersed in a cylindrical container having a mesh-like bottom and having an inner diameter of 26 mm; the cylindrical container is placed in a container containing 40 g of a physiological saline solution, the water-absorbent resin particles are caused to absorb the physiological saline solution for 30 minutes from the bottom of the cylindrical container, and thereby a swollen gel is obtained; and non-pressurization DW, which is measured in a state where another 0.3 g of the water-absorbent resin particles is uniformly dispersed on the swollen gel in the cylindrical container, is defined as liquid suction power.

Water absorbent resin particles, absorbent, absorbent article and liquid suction power measurement method

Disclosed is a method for improving a water absorption amount under load by a powder, the method including shaking a powder containing a plurality of water absorbent resin particles while applying a load to the powder. A maximum value of an acceleration received by the powder to be shaken may be 0.050 to 4.0 G.
