Abstract
A smooth-textured non-woven, superabsorbent particle-impregnated fibrous structure is disclosed. The web exhibits an improved smooth surface texture. The structure contains from 50% to 80% of ion sensitive SAP having a particle size of less than 200 microns, wood pulp fibers and cellulose acetate fibers, each in preferred specified amounts indicated herein. The superabsorbent, ion sensitive polymer particle-impregnated fibrous structure is made from an aqueous, wet-lay process in which an aqueous furnish comprises solids of fibers and superabsorbent, ion sensitive polymer and dissolved salt, such as preferably, Na.sub.2 SO.sub.4. The furnish is passed over a moving foraminous support, such as a Fourdrinier wire, and a wet web structure is formed, followed by drying.
