Abstract
The present invention provides a pre-expanded tampon pledget formed from cellulosic absorbent fibers. The fibers are not tightly compressed, thus, the pledget has a reduced fiber density. As a result, a softer, more pliable pledget is formed that not only increases user comfort during use, but also affords a user with comparable and/or increased leakage protection over conventional tampons or tampon pledgets.
