Title: ABSORBER, METHOD FOR MANUFACTURING SAME, AND ABSORBENT ARTICLE
Abstract:
Provided is an absorber (100) comprising: an absorbent core (110) that includes hydrophilic fibers and particulate superabsorbent polymer; and a core wrap (120) that covers the absorbent core. The absorber (100) has: a length direction, a width direction, and a thickness direction, and a skin side surface and a non-skin side surface; and at least one region which has a superabsorbent polymer content of 40 to 85 mass% and an average density of 0.15 g/cm3 or more, and which has, on one or both of the skin side surface and the non-skin side surface, a plurality of interspersed recesses and projections positioned between the plurality of recesses. For two arbitrary adjacent recesses in the length direction of the absorber when the absorber is viewed in plan view and the portion of the projection positioned between the two arbitrary adjacent recesses, the average value of basis weight of the superabsorbent polymer of the two arbitrary adjacent recesses is less than the basis weight of the superabsorbent polymer of the portion of the projection. Also provided are an absorbent article comprising the absorber and a method for manufacturing the absorber.
