  • Bacteria trapping fibrous material
    Patent number: 7947292
    Abstract: The invention concerns the use of a fiber modified with functions capable of interacting with microbial cell wall proteins for immobilizing micro-organisms in hygiene products. Those functions are particularly capable of interacting with anionic groups and amine groups, and are especially cationic groups and aldehydes, respectively. The fibers may be synthetic or cellulosic. Also hygiene products containing these fibers are described.
    Type: Grant

  • Alkali-neutralising superabsorbent products
    Patent number: 7491862
    Abstract: A superabsorbent article of the invention having improved odour control and microbial control, comprises a liquid-impervious back layer, a liquid-absorbing intermediate layer containing a partially neutralized, acidic hydrophilic polymer, especially a surface-crosslinked polyacrylate, and a liquid-pervious, non-absorbing top layer, and is characterised by comprising an alkali-neutralising agent which is evenly distributed in said absorbing intermediate layer.
