An absorbent mixture, as made from fibers formed into a fibrous web and a polymerizable, cross-linkable material, in a liquid carrier. The material, when polymerized and cross-linked, results in a superabsorbent polymer. The material, in the liquid carrier, is dispersed within the fibrous web, as dispersed inclusions, and is polymerized and cross-linked in situ, within the fibrous web, so as to form a composite web comprising the fibrous web and the superabsorbent polymer, as dispersed particles, at least some of which are bound to fibers from the fibrous web. The composite web is ground, so as to cause some of the superabsorbent polymers to become particulate while fragments of the superabsorbent polymer remain bound to fibers from the fibrous web. Before the composite web is ground, it may be provided with a fibrous layer or fibrous layers in intimate contact therewith, and also compressed.

An absorbent mixture formed from a fibrous body including polymerized, cross-linked material having absorbent properties, at least some of which is bound to fibers of said fibrous body, said mixture comprising (a) first particles, each comprised of said polymerized, cross-linked material, and (b) second, two-phase particles, each having a fibrous phase comprised of particles of said fibers and a polymerized, cross-linked phase comprised of fragments of said cross-linked material bound to the particles of fibers of the fibrous phase, wherein at least some of the first particles and at least some of the fragments are broken from larger particles of said cross-linked material after said cross-linked material is bound to the fibers from which said particles of fibers of said fibrous phase are formed, said first particles being loosely distributed within said second particles.
