  • 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.

  • Publication number: 20040180998
    Abstract: The present invention relates to hydrophilic polymeric compositions for making a liquid impermeable moisture vapour permeable structure, for example by forming the composition into a layer or coating onto a suitable substrate for example a microporous film and to composite structures comprising the compositions. The hydrophilic polymeric compositions of the present invention do not solidify at room temperature, but remain viscous or “creamy”. This prevents layers made from the hydrophilic polymeric composition of the present invention from settling as a film so that delamination of a composite structure comprising the hydrophilic polymeric composition coated into a layer onto a suitable substrate is avoided. The hydrophilic polymeric compositions of he present invention can find a variety of applications wherein liquid imperviousness and moisture vapour permeability are desirable.

  • Publication number: 20030121101
    Abstract: Disposable covering sheet for bedding articles that is moisture vapour permeable and liquid impermeable and comprises at least a moisture vapour permeable fibrous layer and a liquid impermeable but moisture vapour permeable film layer of preferred thermoplastic compositions. Use of the disposable covering sheet as, for example, a mattress or pillow cover provides increased comfort to the user. The disposable covering sheet disclosed herein can be used in a variety of applications, particularly when the benefits of moisture vapour permeability, liquid imperviousness, disposability and increased in-use comfort are desired.
