  • Patent number: 9163355
    Abstract: A composite structure mainly composed of hydratable fine fibers in the form of microfibril and a water swellable solid body, the fibers being obtained from cellulose or derivatives thereof, and at least part of the surface of the solid body is covered with the fine fibers. The absorbent composite can be formed in various form of, for example, particle, pellet, sheet and the like, especially of a sheet type with a supporting sheet of a non-woven fabric. The present invention further provides a method of making the composite structure.

  • Publication number: 20140083889
    Abstract: Diaper packaging having a reduced manufacturing cost may be created by bagging stacks of diapers and bundling the bags. Bands may be applied circumscribing the bundled bags of diapers. One band may be applied along a first direction perpendicular with the length of the stacked diapers. A second band may applied in a second direction parallel with the length of the stacked diapers. The bags of diapers may include several stacks of diapers, and the bundles may include several bags of diapers. For certain bundle configurations of packaged diapers, additional bands may be placed circumscribing the bundles for improved stability. Packaging by banding bundles of diapers may also be used to package other personal care articles and absorbent articles.

  • Patent number: 8445068
    Abstract: A method for coating a dispersion slurry containing a solid SAP dispersed in a dispersion medium on a surface of a substrate sheet are provided. 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.
