Abstract
A tampon comprising an absorbent formed by compression molding of fibers having (A) a dry strength of at least 4.0 g/d (grams/denier), (B) a wet strength of at least 3.0 g/d, (C) a wet strength at a 5% elongation of at least 1.0 g/d, and (D) a wet elongation lower than 3.0% under a load of 0.5 g/d.
Claims6
In a tampon comprising an absorbent material composed of compression molded fibers, the improvement which comprises:
- said fibers consist essentially of polynosic rayon fibers having a dry strength of at least 4.0 g/denier, a wet strength of at least 3.0 g/denier, a wet strength at a 5% elongation of at least 1.0 g/denier and a wet elongation of not more than 3.0% under a load of 0.5 g/denier.
