ABSTRACT:
Flexible absorbent laminates made from crushed films of lightly crosslinked or water-swellable hydrophilic polymers with layers of wicking substrates are disclosed. The crushed laminates are made by drying the laminates to less than 8% moisture and crushing them preferably between a yieldable roller and an enbossed roller. The crushed laminates have a tissue-like feel at low relative humidities with rapid absorption and are useful to make baby diapers or adult diapers.
