ABSTRACT:
A wet-laid absorbent sheet includes a mixture of pulp-derived papermaking fibers and synthetic polymer fibers, a strength agent selected from carboxymethylcellulose and anionic starch as well as an epihalohydrin/amine functional wet strength resin. Also included is an anionic olefin copolymer resin effective to increase the wet/dry tensile ratio of the sheet.
