Topsheet for Use in Disposable Body Fluid Absorptive Goods |
摘要 |
A topsheet for use in body fluid absorptive goods comprises an upper sheet 7 having a skin-contacting area 14 and liquid passages 13 and a lower sheet 8 underlying the upper sheet 7 and defining cavities 20 therewith. The lower sheet 8 is welded to the upper sheet 7 around lower openings 12 of the respective liquid passages 13 so as to restrict deformation of these passages which would otherwise possibly occur. The lower sheet 8 is of melt-blown fibres and the upper sheet 7 may comprise two layers of melt-blown fibres or may be of thermoplastic film. <IMAGE> |
