Abstract
A catamenial tampon is disclosed for absorbing menstrual fluid. The tampon includes a compressed pledget having a major and a minor radius of curvature. Zones of different density fibers are arranged adjacent to each radius of curvature and the zones can extend substantially the entire length of the pledget. The pledget is constructed of absorbent fibers which are enclosed by a cover. A withdrawal string is attached to the pledget and facilitates removal of the tampon from a woman's vagina. The absorbent is compressed into an elongated, generally cylindrically shaped pledget having a zone of high density fibers and a zone of low density fibers. After compression, the low density fibers will expand and form a curved tampon.
