Abstract
A densified web of cellulose fibers has a high absorbent capacity and good wet strength. The web is produced by combining cellulose fibers with a bonding agent, activating the bonding agent, allowing it to contact the cellulose fibers, and thereafter deactivating the bonding agent. The web is thereafter compressed in a cooled state to form a densified web. The web exhibits an absorbent capacity superior to that of prior densified and bonded webs.
