Title:
ABSORBENT SHEET, ABSORBENT ARTICLE, AND ABSORBENT-SHEET MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2021/132338
Kind Code:
A1
Abstract:
An absorbent sheet (1) includes a first fiber sheet (11), a second fiber sheet (12), and water-absorbent polymers (13) disposed between the fiber sheets (11, 12). The fiber sheets (11, 12) are joined by an adhesive (15). The absorbent sheet (1) is disposed in such a manner that a gap in which the water-absorbent polymers (13) can be macroscopically visible is not observed in an area where the water-absorbent polymers (13) are disposed. In the area, the fiber sheets (11, 12) have regions (17) in which the fiber sheets are directly joined only by the adhesive (15) and not via the water-absorbent polymers (13).
