摘要： A process for forming an absorbent fibrous web composite includes the initial step of forming a fibrous web fromhydrophilic fibers and, optionally, thermoplastic fibers. Then, a superabsorbent polymer is completely formed in situ on or in the fibrous web by adding one or more superabsorbent polymer precursor compositions to the fibrous web using a non-contact process, and performing the polymerization reaction(s) completely on or in the web.

摘要： A process for making an absorbent composite including absorbent fibers, superabsorbent polymer and, optionally, thermoplastic fibers and other ingredients is provided. The synthesis (i.e., polymerization) of the superabsorbent is completely integrated into the process for forming the absorbent composite. Specifically, the polymerization of superabsorbent is initiated from within a plurality of absorbent and/or thermoplastic fibers, which are then formed into a web. The integrated process eliminates the need for separate manufacture of superabsorbent polymer prior to the fiber forming and web forming processes. Also, the superabsorbent polymerthus formed tends to disperse better and remain adhered to the absorbent and/or thermoplastic fibers, providing a stable and uniform absorbent composite for various end use applications.

摘要： A process for making an absorbent fibrous web composite including a stable, controllable dispersion of superabsorbent polymer is provided. A pre-formed web, desirably including cellulose fibers and, optionally, thermoplastic fibers is provided. First and second superabsorbent polymer precursor compositions are added to the fibrous web using separate streams. The first and second superabsorbent polymer precursor compositions combine with each other and chemically react on or in the fibrous web, to form a superabsorbent polymer which sticks to the surface of the fibrous web.
