摘要： The purpose of the present disclosure is to provide a method which is for producing a secondarily dehydrated highly-water-absorbent polymer for a highly-water-absorbent recycled polymer, and by which a highly-water-absorbent recycled polymer having a small residual amount of waste can be simply formed. The production method according to the present disclosure has the following feature.
A method for producing a secondarily dehydrated highly-water-absorbent polymer for a highly-water-absorbent recycled polymer is characterized by comprising: a preparation step for preparing a primarily dehydrated highly-water-absorbent polymer which is obtained by immersing a sanitary article-forming material, which forms a sanitary article, in an acid-containing aqueous solution that contains an acid to form the primarily dehydrated highly-water-absorbent polymer, and separating the primarily dehydrated highly-water-absorbent polymer from the sanitary article-forming material; and a secondary dehydration step for forming a secondarily dehydrated highly-water-absorbent polymer by bringing the primarily dehydrated highly-water-absorbent polymer into contact with a polyvalent metal ion supply source that can supply polyvalent metal ions to further dehydrate the primarily dehydrated highly-water-absorbent polymer.-

摘要： A pet diaper according to an aspect extends in a lateral direction to be disposed along a waist of a pet and in a longitudinal direction orthogonal to the lateral direction and connecting a ventral side of the pet to a dorsal side of the pet. The pet diaper has a main body including an absorbent core. A tail hole allowing feces of the pet to pass therethrough is formed in the main body. The pet diaper further comprises an elastic member attached to the main body in a state of being stretched in the longitudinal direction, the elastic member extending between at least an edge of the tail hole on the ventral side and an edge of the absorbent core on the dorsal side in the longitudinal direction.

摘要： The present invention provides a method for recovering a plastic material from a used nonwoven fabric product said method being capable of suppressing impurities contained in the recovered plastic material. This method comprises: a primary separation step (S2) wherein a highly water absorbent polymer and pulp fibers are separated from a mixture of a plastic material the highly water absorbent polymer and the pulp fibers said mixture being obtained by decomposing a used nonwoven fabric product in an aqueous inactivation solution; and a secondary separation step (S3) wherein the plastic material is recovered by separating the highly water absorbent polymer and the pulp fibers still remaining after the primary separation step from the plastic material by applying a physical impact to the mixture while spraying an aqueous oxidant solution into the mixture in the air.
