<p>A process for preparing an absorbent material in dry form using guar gum, as an exemplification of cis-1,2-diol polysaccharides, which is first hydrated then thickened by cross-linking with borax and finally drying preferably to powder in flake form, preferably by freeze-drying. The resulting particles can absorb up to 100 times their weight or more of aqueous fluids such as urine. Absorbent articles, such as disposable diapers, bandages, and the like are formed with the borax cross-linked guar gum as absorbent In a preferred diaper the dry absorbent particles of the borax cross-linked guar gum are placed in the cells of a cellular or bubble-type substrate.</p> |
