Document Type and Number:
WIPO Patent Application WO/2015/182784
Kind Code:
A1
Abstract:
Provided is a fiber sheet that has a bulky feel and flexibility. The fiber sheet (1) is provided with a surface sheet layer (5) and a flexibility-imparting layer (6). The fiber sheet (1) is embossed and has a binder applied thereto. The flexibility-imparting layer (6) comprises a large number of fibers, and said fibers are configured so as to be densely present in a compressed state in a boundary surface area between the surface sheet layer (5) and the flexibility-imparting layer (6). The surface sheet layer (5) is a paper material that is formed from pulp paper or a material that comprises pulp as a main raw material. The flexibility-imparting layer (6) is formed from pulverized pulp or a material that comprises pulverized pulp as a main raw material. In addition, the surface sheet layer (5) is produced by a papermaking process and the flexibility-imparting layer (6) is layered on the surface of the surface sheet such that the pulverized pulp thereof follows the flow of airflow. Furthermore, the binder is applied after a recessed section is formed by embossing.
