ABSORBENT ARTICLES HAVING LIQUID SHRINKABLE BREATHABLE BACKSHEETS

摘要

The present invention relates to absorbent articles such as sanitary napkins and panty liners which are breathable by the incorporation of a breathable backsheet and have a reduced tendency to exhibit garment wet through. The backsheet comprises at least one vapour permeable, apertured layer comprising a non soluble, liquid shrinkable material such as polyvinyl alcohol. Upon contact with the fluid discharge the material shrinks thereby causing the apertures of the layer to close and hence prevent the passage of liquid through the backsheet onto the garment of the wearer.
