The method may alternatively, or additionally, include the steps of spray drying a wood pulp fiber slurry and/or a slurry of a hydrophilic material, and flash drying the spray dried wood pulp fiber slurry and/or slurry of hydrophilic material.

Abstract: A process for making an absorbent material involves flash-drying a superabsorbent polymer precursor composition. The process may be used to make a superabsorbent-fiber material without the necessity of mixing conventional superabsorbent solid particles with pulp fluff is provided. The synthesis (i.e., polymerization) of the superabsorbent is completely integrated into the process for forming the absorbent material. One or more streams of superabsorbent polymer precursor composition are provided, to which a plurality of individual fibers may be added. The resulting in-situ polymerized superabsorbent-fiber material is then flash-dried and can subsequently be formed into a superabsorbent-fiber composite. The flash-drying is relatively inexpensive and requires little drying time compared to conventional drying methods.

Abstract: A process for making a multifunctional superabsorbent polymer, and for making an absorbent structure containing superabsorbent polymer. The synthesis (i.e., polymerization) of the superabsorbent is completely integrated into the process for forming the multifunctional superabsorbent polymer and/or absorbent structure. More particularly, a monomer solution containing an oxidizing agent, a monomer solution containing a reducing agent, and at least one functional additive are combined to form the multifunctional superabsorbent polymer. A valve can be used to control the liquid drop sizes of the monomer solutions as well as of the oxidizing agent, reducing agent, and functional additive(s). The droplets can be collected on a substrate, resulting in the formation of an absorbent structure.
