Abstract:
A fiber sheet having both a bulky feel and softness is provided. A fiber sheet (1) is provided with a surface sheet layer (5) and a softness imparting layer (6). The fiber sheet (1) is subjected to embossing and a binder is applied to the fiber sheet (1). The softness imparting layer (6) is constituted by a plurality of fibers; and the fibers exist densely in a compressed state in a region of a boundary face between the surface sheet layer (5) and the softness imparting layer (6). Additionally, the surface sheet layer (5) is a paper material formed from pulp paper or a material including pulp as a principal raw material; and the softness imparting layer (6) is formed from crushed pulp or a material including crushed pulp as a principal raw material. Furthermore, the surface sheet layer (5) is manufactured by a paper making process; and the softness imparting layer (6) is formed by laminating crushed pulp along a flow of an airflow on a surface of the surface sheet. Moreover, depressions are formed via the embossing and, thereafter, the binder is applied.
