ABSTRACT:
Wet wipes having improved wet strength, wet thickness and wet toughness are provided by incorporating a wet strength agent in the fibrous web containing pulp fibers and at least five percent by weight man-made fibers and hydraulically entangling the web. No post-formation bonding treatment is employed and the fiber dispersion includes only about 1% by weight of the wet strength additive. The hydroentanglement coupled with the low amount of additive provides unexpected synergistic strength and absorbency characteristics. The wet wipe retains its strength characteristics despite packaging and prolonged storage in a wet condition.
