  • Absorbent member and method of producing the same
    Patent number: 8373016
    Abstract: An absorbent member (10) of the invention has a hydrophilic continuous fiber web (12) and lumpy particles of an absorbent polymer (13) held in the web (12). The absorbent polymer (13) is localized in part in a planar or thickness direction of the absorbent member (10). The continuous fibers in a region (M) in a planar direction of the web (12) where the absorbent polymer is distributed are in a state cut into a large number of staple fibers (122). A method of producing an absorbent member includes the step of spreading lumpy particles of an absorbent polymer (13) on a continuous fiber web (12) and pressing the continuous fibers in part of the web (12) onto the absorbent polymer (13) to cut the continuous fibers.
