Abstract

A highly compressed catamenial tampon, the side surfaces of which comprise loosened fiber ends and the method of producing the same by relative rolling motion of the tampon on a multiplicity of wirelike prongs which penetrate the tampon to a depth of from about one one-hundred twenty-eighth to about onesixteenth inch.

Claims

1. A catamenial tampon comprising an elongated blank of absorbent fibers compressed to useable size, the interior of said tampon being highly compressed and having a density of at least about 0.4 grams per cubic centimeter, the longitudinally extending exterior of said tampon comprising a low-density surface of disturbed fiber ends which are loosened and separated from one another. CM,2Atamenial tampon of claim 1 in which the fiber ends are disturbed to a depth of from between about one sixty-fourth to about five sixty-fourths inch.

3. The catamenial tampon of claim 1 in which said fibers are oriented in a direction generally transverse the longitudinal dimension of the tampon and in which said longitudinally extending exterior contains at least two circumferentially extending slits having a depth of between about one thirty-second to about three thirty-seconds inch.

4. The catamenial tampon of claim 1 which is pierced in a diametrical direction in a multiplicity of locations by an elongated sharp object having cross section dimensions of between about one thirty-second to about three thirty-seconds inch.
