摘要： Short fibers of thermoplastic synthetic resin are fusion bonded to one another to form a nonwoven fabric. The nonwoven fabric is formed on its upper surface with crests and troughs extending in parallel to one another. The crests include first crests having a uniform height dimension from a lower surface of the nonwoven fabric and second crests having a uniform height dimension from a lower surface of the nonwoven fabric which is smaller than the height dimension of the first crests. Density of the nonwoven fabric gradually increases in the order of the first crests, the second crests and the troughs. The first crests are formed so that the density of the first crests remains lower than the density of the second crests even when the first crests are compressed toward the lower surface until the first crests becomes flush with the level of the second crests.

In a cut surface of the nonwoven fabric extending in parallel to a first direction, the composite fibers extend in the first direction with repetitive curvatures in a thickness direction of the nonwoven fabric. In a cut surface of the nonwoven fabric extending in a second direction, the composite fibers 2 extend in the thickness direction TD at an average fiber angle of 75° or less. The individual composite fibers intersect one another and fused together at respective intersection points by fusion of the low fusion point resin forming the sheath component.

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.
