PROCESS FOR ADDING SUPERABSORBENT TO A PRE-FORMED FIBROUS WEB VIA IN SITU POLYMERIZATION

摘要

A process for forming an absorbent fibrous web composite includes the initial step of forming a fibrous web from hydrophilic 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.
