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.

A process for producing a creped sheet product comprising:
- a. applying an additive composition comprising a flexible superabsorbent and a film forming component to a moving creping surface;
- b. pressing a base sheet against the creping surface after the additive composition has been applied, the additive composition adhering the base sheet to the creping surface;
- and
- c. removing the base sheet from the creping surface with a creping blade, wherein the base sheet comprises, by weight, from about 0.1% to about 3% additive composition.
