摘要:
A nonwoven sheet for use in absorbent articles such as disposable diapers which is capable of reducing the range of surface diffusion of, and reducing re-adhesion to the skin of, highly viscous fluid excretion. The nonwoven sheet has mutually perpendicular longitudinal, transverse and thickness directions, and has in the aforementioned thickness direction a front surface and a back surface opposite thereof. Ridges and grooves are formed alternately so as to extend in parallel in the aforementioned longitudinal direction and so as to form repeated undulations in the aforementioned transverse direction. The nonwoven sheet has a bottom surface which, when the aforementioned nonwoven sheet is placed on a horizontal surface with the back surface (opposite of the front surface in contact with the skin of the wearer) down, is the surface that contacts the aforementioned horizontal surface. On the back surface of the aforementioned grooves are formed in the aforementioned longitudinal direction alternately areas where the height from the bottom surface is relatively high and parts corresponding to the bottom surface. Openings are formed at least in the areas where the height from the bottom surface is relatively high, and a space is provided below said openings.

A sheet of nonwoven fabric for use in absorbent articles such as disposal diapers, sanitary napkins, wipes, etc., the sheet of nonwoven fabric being suitable for holding high-viscosity excreta such as soft feces. The sheet of nonwoven fabric has, formed in a first surface thereof, a plurality of ridges and grooves which extend in the machine direction. The sheet comprises a first fibrous layer and a second fibrous layer, the first fibrous layer being located on the first-surface side and the second fibrous layer being located on the second-surface side, which is on the reverse side from the first surface. The second fibrous layer comprises fibers having the ability to be crimped, and the first fibrous layer comprises heat-fusible fibers which are not crimped at the crimping initiation temperature of the fibers having the ability to be crimped. In a plan view from the first-surface side, the peripheries of the ridges have a shape which is composed of repeated meanders.
