  • Patent number: 10195095
    Abstract: Absorbent article suppressing occurrence of malodor after use while preventing a rash on a wearer's skin. The absorbent article includes an absorbent body, and a fumaric acid-supported sheet disposed on a skin surface side of the absorbent body. The fumaric acid-supported sheet is a sheet which supports fumaric acid particles having an average particle diameter of 30 ?m or less, and/or a sheet in which at least a part of constituent fibers is coated with fumaric acid. When being in contact with the body fluid or the like, fumaric acid is not immediately but slowly dissolved so that alkalization at the area around fumaric acid can be prevented over a long period of time. In addition, fumaric acid has an action of inhibiting proliferation of putrefactive bacteria and, therefore, can prevent occurrence of malodor from the absorbent article having absorbed the body fluid or the like.

    Abstract: A film that is both biodegradable and flushable, and yet can still act as a barrier to water or other fluids during use, is provided. More particularly, the film contains a water-dispersible core layer that helps the film to lose its integrity after being flushed, as well as a water-barrier skin layer that helps maintain the integrity of the film during use. The nature and relative concentration of the components in the water-barrier layer are selectively controlled to achieve a combination of different functions. That is, the majority of the polymers employed in the water-barrier layer are biodegradable polymers that can be degraded by microorganisms while in an aqueous environment (e.g., septic tank, water treatment facility, etc.). To even further enhance the overall renewability of the layer, a relatively high amount of the biodegradable polymers are starch polymers, which are also renewable.

    Abstract: A biodegradable and flushable film is generally provided. The film can be a multi-layer film including a water-dispersible core layer that comprises a water-soluble polymer; and a water-barrier skin layer positioned adjacent to the water-dispersible core layer. The water-dispersible core layer constitutes from about 50 wt. % to about 99 wt. % of the film, while the water-barrier skin layer constitutes from about 1 wt. % to about 50 wt. % of the film. The biodegradable polymers of the water-barrier skin layer can constitute from about 80 wt. % to 100 wt. % of the polymer content in the water-barrier skin layer, with from about 10 wt. % to about 90 wt. % of the biodegradable polymers being polyalkylene carbonate and from about 10 wt. % to about 90 wt. % of the biodegradable polymers being biodegradable polyesters. The film may be used as a packaging film or as a backsheet of an absorbent article.

  • Patent number: 8329978
    Abstract: An absorbent product has a top sheet, an absorbent core and a back sheet. The absorbent core includes 40% by weight or more of high absorbent resin powder and it is possible to slim down the absorbent core while keeping a sufficient amount of absorption to thereby achieve slimming down of the absorbent product. A top sheet lower part contacting the high absorbent resin powder in the absorbent core includes hydrophilic fibers having water retention characteristics, and moisture is temporarily retained in the top sheet lower part before reaching the absorbent core and rapidly disperses in a range facing the absorbent core of the top sheet lower part. As a result, it is possible to reliably absorb the moisture of excrement in the absorbent core and to simplify a structure of the absorbent product.
