WIPO Patent Application WO/2021/200436
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a nonwoven fabric sheet with which it is possible to make an excreted liquid returned from an absorber of an absorbent article mildly acidic while maintaining a water absorption property thereof, the nonwoven fabric sheet having a limited influence on the skin and contributing to suppresion of rusting of metal portions of a manufacturing facility during a manufacturing process, thus facilitating maintenance of the manufacturing facility and enabling efficient manufacturing. Provided is a nonwoven fabric sheet in which a plurality of layers are laminated and integrated with each other, wherein a pH adjuster is not added to a surface of the laminated nonwoven fabric but is added on the inside of the laminated nonwoven fabric. Further, when a liquid having a pH of 7.0 or more passes through the nonwoven fabric sheet, the pH of the liquid after passing through the nonwoven fabric sheet becomes lower than the pH of the liquid before passing through the nonwoven fabric sheet.
