摘要： Provided is a liquid-permeable nonwoven fabric having improved in air permeability in the thickness direction thereof, formed on its surface with ridges and troughs extending in parallel to each other in one direction. A nonwoven fabric formed of thermoplastic synthetic short fibers fused together is formed on its upper surface with ridges and troughs extending in parallel to each other in a longitudinal direction. In a cross section of each ridge taken in the transverse direction, the ridge includes opposite lateral regions in which the short fibers are densely distributed and a central region defined between the opposite lateral regions and in which the short fibers are sparsely distributed. The short fibers in the central region include short fibers in a crest of the ridge adapted to connect the opposite lateral regions to each other. This invention also discloses a method for manufacturing of the nonwoven fabric.

摘要： A nonwoven-fabric sheet having a high liquid permeation rate and a process for producing the sheet. The nonwoven-fabric sheet comprises two layers, a first layer and a second layer, and is characterized in that the first layer has a plurality of ridges and grooves which extend in parallel in the lengthwise direction, that the first layer comprises heat-fusible fibers and the second layer comprises crimped fibers, and that the sheet has an average fiber angle of 70 or less in a cross-section parallel to the lengthwise direction. The nonwoven-fabric sheet can be produced by stacking a web comprising fibers having latent crimping properties and a web comprising heat-fusible fibers, ejecting a fluid from a plurality of nozzles arranged in the width direction, while conveying the stack, to form ridges and grooves, heating the stack using a means that reduces resistance against the crimping properties of the fibers having latent crimping properties, thereby crimping the fibers having latent crimping properties, and then fusion-bonding the heat-fusible fibers.

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.
