  • Liquid absorbing thermoplastic materials and the utilization thereof in absorbent articles
    Publication number: 20080039811
    Abstract: The present invention relates to improved liquid absorbing thermoplastic materials useful for example as absorbent materials for disposable absorbent articles. The liquid absorbing thermoplastic materials comprise A) thermoplastic compositions comprising thermoplastic polymers and suitable compatible plasticisers and B) superabsorbent particles dispersed in the thermoplastic compositions. Such liquid absorbing thermoplastic material, preferably in form of hot melt compositions, can be utilised in the absorbent cores of disposable absorbent articles, such as sanitary napkins, panty liners, disposable diapers, nursing pads and the like for completely or partially substituting said absorbent cores.

  • Disposable, moisture vapour permeable, liquid impermeable covering sheet having odour reduction properties
    Publication number: 20030172458
    Abstract: The present invention relates to a disposable covering sheet which is moisture vapour permeable and liquid impermeable and has odour control properties and, if desired, also active agent releasing properties. The disposable covering sheet comprises at least a moisture vapour permeable layer and a liquid impermeable but moisture vapour permeable film layer of thermoplastic compositions. The disposable covering sheet such as, for example, a mattress cover or a pillow cover gives a better comfort to the user by providing odour control properties and, if desired, also active agent releasing properties. The disposable covering sheet of the present invention can find a variety of applications wherein moisture vapour permeability and liquid imperviousness combined with specific odour control properties and preferably also active agent releasing properties are desirable.
