Title:
WATER-ABSORBING RESIN COMPOSITION, ABSORBER, ABSORBENT ARTICLE, AND METHOD FOR SEPARATION PROCESSING OF WATER-ABSORBING RESIN PARTICLES FROM ABSORBENT ARTICLE
Document Type and Number:
WIPO Patent Application WO/2023/074861
Kind Code:
A1
Abstract:
Provided is a water-absorbing resin composition containing water-absorbing resin particles and activated carbon. When the water-absorbing resin composition is used in an absorbent article, gel absorbed by the water-absorbing resin composition is stable in an environment during ordinary usage (wearing) of the absorbent article. After the absorbent article is used, the gel strength can be adjusted to a suitable strength for disposal (gel separation operation) by processing for a long time under high-temperature conditions. The water-absorbing resin composition contains the water-absorbing resin particles and activated carbon disposed on the surface of the water-absorbing resin particles. The water-absorbing resin particles are subjected to a surface-crosslinking process, and the physiological saline solution absorption amount of the water-absorbing resin particles is 30 to 80 g/g.
