Abstract

An absorbent composite material may be manufactured by applying a flexible absorbent binder polymer (FAB), also referred to herein as a flexible superabsorbent, during the creping step of conventional tissue manufacturing. As such, the costly process of applying FAB to a substrate by spraying or printing followed by drying may be eliminated. The creping step has the additional advantage of improving the flexibility and softness of the FAB treated fibrous web.
