The method is characterized in that a first region and a second region are formed on the surface of the substrate sheet with a convex-and-concave pattern wherein the first region have the coating layer in thicker thickness and the second region have the coating layer in thinner thickness or does not scarcely have the coating layer, by means of positioning the rotating pattern roll over the substrate sheet via the cover film, of supplying the dispersion slurry between the substrate sheet and the cover film while rotating the rotating pattern roll, and of pushing the coating layer with the rotating pattern roll via the cover film, when the coating layer of the dispersion slurry is formed.

Abstract: The present invention has an object to provide an absorbent product capable of preventing the absorbing rate from significantly lowering with the elapse of time, from the start of use to a final stage when the absorbing capacity of the product reaches a limit, and having a very small re-wet amount. The above-mentioned object may be attained by an absorbent product with a liquid-impermeable surface sheet positioned on the upper side, a liquid-impermeable back sheet positioned on the lower side, and an absorber containing super absorbent polymer to absorb discharged liquid positioned between the surface sheet and the back sheet, wherein a flow passage is provided to allow a part or all of the discharged liquid supplied to the surface sheet to move to a side of the back sheet.

Abstract: A disposable absorbent article includes a topsheet, a backsheet and an absorbent core disposed therebetween. One or more of the backsheet, topsheet, and absorbent core is constructed of an absorbent composite that includes an absorbent layer of hydratable fine fibers in the form of microfibril obtained from cellulose or a derivative thereof and super absorbent polymer (SAP) particles bonded together by the hydratable fibers, and a nonwoven substrate supporting the absorbent layer such as SMS. The absorbent layer is coated over the surface of the nonwoven substrate. The core may include one uniform layer of the absorbent composite or a composite having one layer of the nonwoven substrate and a plurality of segmented absorbent layers applied thereon. In the latter design, the absorbent layers are spaced apart from one another to expose surface sections of the substrate. These non-coated surface sections provide wicking zones which allow room for the absorbent layers to expand and prevent gel blocking.
