ABSORBENT ARTICLE COMPRISING POLYMERIC FOAM WITH SUPERABSORBENT AND INTERMEDIATES |
摘要 |
Absorbent articles are described comprising an absorbent composite. The absorbent composite comprises a first absorbent layer comprising a polymeric foam having an average cell size of at least 100 microns and discrete pieces of superabsorbent polymer dispersed within the polymeric foam; and a second absorbent layer in fluid communication with the first absorbent layer. Favored articles include disposable diapers, feminine hygiene articles, and adult incontinence articles. Also described is a polyurethane foam is described having an average cell size of at least 100 microns. The polyurethane foam is the reaction product of a polyether polyol having polyethylene oxide units and at least one polymeric polyisocyanate that lacks urethane linkages. The polyureth ane foam comprises at least 5 wt-% of discrete pieces of superabsorbent polymer. Also described are various composites comprising the polyurethane foam described herein in combination with another substrate such as a second absorbent layer, a fluid impervious backsheet, and/or a fluid pervious topsheet. |
