摘要:
Provided is a sheet of nonwoven fabric which has surface irregularities and is for use as the surface sheet or absorbent of, for example, a paper diaper, the shape of the surface irregularities being less apt to be changed by external pressure, etc. The sheet of nonwoven fabric has a machine direction (MD), a cross direction (CD), a thickness direction (TD) which are perpendicular to one another, and has an upper surface (A) and a lower surface (B) in the thickness direction. The upper surface has a plurality of protrusions (2) continuously extending, in parallel, in the cross direction and further has a plurality of recesses (3) that are located between the adjacent protrusions and extend in the cross direction. The sheet of nonwoven fabric comprises a first fibrous layer (4) and a second fibrous layer (5), the first and second layers being located on the upper-surface side and the lower-surface side, respectively. The first fibrous layer comprises heat-fusible fibers, and the second fibrous layer comprises coil-shaped three-dimensional crimp fibers. The coil-shaped three-dimensional crimp fibers of the second fibrous layer have been oriented mainly in the machine direction and have formed a network due to entanglement thereof without having been fused at the sites where the crimp fibers cross one another.
