Absorbent materials and absorbent articles

Abstract

To provide an absorbent article applying an absorption performance according to a part, suppressing leakage of SAP, deviation and gel blocking, and comprising an absorber with preferable absorption performance and wearing feeling.SOLUTION: An absorber 10 includes no fluff pulp, and comprises: a high absorbent sheet 15; a plurality of bag bodies 60 including a high absorbent polymer; and a hydrophilic sheet 20 wrapping the high absorbent sheet 15 and the bag bodies 60. The high absorbent sheet 15 comprises: a substrate non woven fabric 11 including a raised surface 11a facing a top sheet 25; and a high absorbent polymer 12 fastened and carried between raised fibers 11x of the raised surface 11a. The bag bodies 60 include a bag body main body formed of a hydrophilic nonwoven fabric, and a high absorbent polymer sealed in the bag body main body. In the absorber 10, the plurality of bag bodies 60 is fastened to the raised surface of the high absorbent sheet 15. An absorbent article 50 includes the absorber.SELECTED DRAWING: Figure 2

Claims
