An absorbent article is disclosed which exhibits improved fluid management. The article includes an absorbent having first and second oppositely aligned surfaces and a longitudinally extending central axis. A bicomponent cover is positioned over the first surface of the absorbent and includes a first and a second material. The first material has openings formed therein and is aligned along the longitudinally extending central axis of the absorbent. The second material is nonapertured and is secured to, or positioned adjacent to, the outer periphery of the first material. The first and second materials cooperate to enclose the absorbent. Positioned between the first material and the first surface of the absorbent is a separation means. The separation means directs fluid from the body downward, in the z direction, away from the bicomponent cover, and outward in the x and y directions to provide a more efficient use of the absorbent material. The absorbent article further contains a liquid-impermeable baffle which is positioned adjacent to the second surface of the absorbent.

The invention relates to a system for fastening refastenable garment such as diaper or incontinent garment in which a tape and polymer backing material for the garment are provided such that tape may be removed after refastening to the diaper without tearing of the polymer material. The system of the invention utilizes a polypropylene tape material that is embossed on the outer surface and smooth on the adhesive-carrying surface. The adhesive on the tape is a semihard adhesive that provides high adhesion values to the polymer that nevertheless may be peeled free for removal of the tape and subsequent refastening. The polymer forming the outer backing if the diaper is a relatively thick, embossed polymer sheet. In the refastenable system of the invention the strength and adherence of the tape to the strong, embossed polymer backing sheet is controlled so as to achieve secure fastening with release of the adhesive from the embossed sheet without tearing.

An aqueous adhesive composition containing a graft copolymerized product of low amylose starch and acrylamide with rheological and remoistening adhesive properties suitable for coating low basis weight kraft paper on transfer roll coating equipment to make remoistenable sealing tapes. The desired properties of the adhesive composition are obtained by a controlled graft copolymerization together with a simultaneous gelatinization of the starch at temperatures below 210.degree. F. and with the essential addition of cupric or ferric ions before initiating the reaction. The resulting coatable adhesive has a comparatively low viscosity as required for transfer roll coating while retaining the improved adhesion properties of the acrylamide.
