Abstract:
A wet-laid, superabsorbent, ion sensitive polymer particle-impregnated structure comprising 50% to about 80% water insoluble, water swellable ion sensitive polymer particles and 20% to 50% fibers, said structure prepared by a process comprising:(a) preparing a fiber and water insoluble, water-swellable, superabsorbent, ion sensitive polymer particle containing slurry, essentially all of said particles, before use, have a particle size of less than 250 microns,(b) combining said slurry with a water solution containing a salt to form a furnish,(c) forming a wet web from said furmish on a moving foraminous support,(d) washing said wet web in-line with water, and(e) drying said web,wherein the residual salt content of the dried web is from less than 40%, and wherein said web has an absorbency under load (AUL) of greater than or equal to 13 g/g.
