  • Absorbent article
    Patent number: 7884259
    Abstract: An absorbent article including a fiber aggregate formed by opening the tow, a super absorbent polymer particle, and a sheet covering these components. The super absorbent polymer particle are bonded to the sheet with an adhesive that is applied in a continuous plane to the entire surface or the substantially entire surface at least at the portion to be provided with the super absorbent polymer particle in this sheet.
    Type: Grant
