ABSTRACT:
Surface-hydrophilic perforated sheets comprise a fluid-permeable hydrophobic sheet having a multiplicity of holes for fluid passage. The sheets are coated with a rubber-like material insoluble in aqueous fluid but having surface-hydrophilic properties, whereby the surface of the sheet is rendered hydrophilic. The sheets are particularly useful as cover sheets for absorbent structures such as diapers, bandages, and catamenials.
