A method for producing water-absorbent resin particles, an absorbent article, a water-absorbent resin particle, and a method for suppressing liquid leakage of the absorbent article.

摘要

Formula: When the liquid permeation ratio A calculated by the liquid permeation ratio A [%] = (water absorption amount B [g / g] / water absorption amount C [g / g]) × 100 is more than 0% and 60% or less. Certain, water-absorbent resin particles are disclosed. When the physiological saline supplied through the spunbonded non-woven fabric is absorbed by the water-absorbent resin particles of 1.00 g by the DW method under no pressure, the water-absorbent resin particles absorb the water-absorbent amount B. It is the mass of physiological saline per 1 g of water-absorbent resin particles that is absorbed within 5 minutes after the start of. The water absorption amount C is the mass of the physiological saline solution per 1 g of the water-absorbent resin particles, which is absorbed when 2.0 g of the water-absorbent resin particles swell in 500 g of the physiological saline solution over 60 minutes.
