  • Publication number: 20240180757
    Abstract: The present disclosure relates to absorbent hygiene articles having a substantially continuous channel (4) and a wetness indicator (5) which can indicate the presence of a liquid bodily exudate in the article. The continuously extending wetness indicator (5), as seen from the garment-facing side of the article, is coincident with the longitudinal center line (LCL) of the article and comprises an overlapping portion (51) superposed with at least part of the longitudinally extending channel central section (41), and an exposed portion (52) superposed with absorbent material at least partially surrounded by channel sections (42,43) closer to the front transverse edge (3) of the article. Such a combination of channel and wetness indicator may offer an easy-to-manufacture absorbent article able to indicate a sequence of wetting events and to give an accurate indication of how full the article is.

  • Publication number: 20230149224
    Abstract: The present invention relates to an absorbent core (1) for an absorbent article, comprising absorbent material and a continuous channel (4) substantially free of said absorbent material. Said channel (4) comprises at least (i) one longitudinally extending central section (41) coincident with the longitudinal center line (LCL), (ii) four longitudinally extending lateral sections (42), (iii) four diagonally extending diagonal sections (43), and (iv) one transversally extending ending section (44, 44?). A continuous channel made of at least these essential channel sections provides fast absorption, good liquid distribution throughout the entire core, improved fit and comfort and minimizes the risk of leakage.

  • Publication number: 20220160553
    Abstract: The present invention relates to absorbent cores for use in absorbent articles, preferably of the disposable personal hygiene type. It discloses absorbent cores comprising a foam layer incorporating a nonwoven fabric and having a top surface and a bottom surface, said foam layer top surface comprising one or more indented compressed portions and one or more raised non-compressed portions. The foam layer has openings extending through the foam and the nonwoven fabric. The absorbent core further comprises, joined to the bottom surface of the foam layer, a nonwoven comprising superabsorbent polymers. Absorbent cores of the present invention provide a fast acquisition of body exudates and a good liquid retention capacity. This is further achieved in a simple and cost-effective way without complex and considerable foam formulation and processing requirements.
