摘要： Provided are: a water-absorbing agent achieving, in a balanced manner, both good physical properties and a decrease in speed of coloration with lapse of time even if the water-absorbing agent has a high moisture absorbing speed due to having a large specific surface area; and an absorbent body having a low ratio of pulp and achieving, in a balanced manner, both good physical properties suitable for a thin disposable diaper and a decrease in speed of coloration with lapse of time. The absorbent body contains a hydrophilic base material and a water-absorbing agent which contains: surface-crosslinked water-absorbing resin particles having a non-uniformly pulverized shape; α-hydroxycarboxylic acid (salt); and an aminocarboxylic acid-based chelating agent and/or a phosphorus-based chelating agent, a point plotted along an x-axis that represents an amount (x1 mol %) of α-hydroxycarboxylic acid (salt) extracted from the water-absorbing agent and along a y-axis that represents an amount (y1 mmol %) of an aminocarboxylic acid-based chelating agent and/or a phosphorus-based chelating agent extracted from the water-absorbing agent being within a range that satisfies a specific relational formula of x1 and y1, the water-absorbing agent having a moisture absorbing speed of 120 mg/g/hr or more at a temperature of 40±1° C. at a relative humidity of 75±1% RH.

摘要： [Problem] In an embodiment involving addition of a chelating agent in an upstream process of the process for production, such as the polymerization step, the residual ratio of the chelating agent in the final product, a particulate water-absorbing agent, is improved.
[Solution] A particulate water-absorbing agent having a poly(meth)acrylic acid (salt)-based water-absorbing resin as a main component, containing a chelating agent having a nitrogen atom and an inorganic reducing agent having a sulfur atom, wherein the particulate water-absorbing agent has a chelating agent ratio of 0.8 to 1.8, as calculated by the following procedures (a) to (c): (a) subjecting the particulate water-absorbing agent to a predetermined impact test; (b) sieving the particulate water-absorbing agent subjected to the impact test into a particle group 1 with a particle size of less than 300 μm and a particle group 2 with a particle size of 300 μm or more and less than 850 μm using a JIS standard sieve; and (c) quantifying a content C1 of the chelating agent present in the particle group 1 and a content C2 of the chelating agent present in the particle group 2, and then dividing the C1 by the C2.-

摘要： A nozzle includes: a flow path allowing gas to flow; tip opening portion(s) formed on a tip side of the flow path; a base end opening portion formed on a base end side of the flow path; and side hole(s) which is formed on the base end side from the tip opening portion and allows a part of the gas flowing through the flow path to be discharged toward the base end side. The tip opening portion(s) is formed in a direction of the flow path. The side hole(s) is formed along a circumferential direction of the flow path. When the gas is supplied from the base end opening portion, a ratio (Q1a/Q1b) of a flow rate (Q1a) of the gas discharged from the tip opening portion(s) and a flow rate (Q1b) of the gas discharged from the side hole(s) is 0.05 to 0.7.
