Abstract

A tampon having a series of parallelly aligned fibers is fused to a withdrawal string positioned transversely near one end of the fibers. The aligned fibers are then rolled in a jelly roll configuration in a manner which allows the free end of the withdrawal string to be centrally positioned at the bottom of the tampon at the inner end of the jelly roll.

Claims

1. A tampon comprising in combination an absorbent matrix of parallelly aligned, closely packed fibers and a withdrawal string a portion of which is fusibly attached near one end of said fibers, said fibers having ends substantially equidistant from said withdrawal string near the points of attachment with said fibers also being transversely rolled to form a jelly roll configured cylindroidal fibrous mass.

2. A tampon according to claim 1 wherein the absorbent matrix contains fusible fibers.

3. A tampon according to claims 1 or 2 wherein the withdrawal string is fusible.

4. The tampon according to claim 1 wherein at least 10% of the fibers are between 3 and 4 inches long.

5. The tampon according to claim 1 wherein the pledget is a spiral of increasing length towards the center of the pledget after rolling.

6. The tampon according to claims 1, 2 or 4 wherein the fibers include superabsorbent.

7. The tampon according to claims 1, 2 or 4 wherein a solid, dispersible lubricant is coated over the outside of the pledget.

8. A process for making a tampon comprising:

(a) positioning a plurality of fibers so that they are essentially aligned at one end and essentially parallel to each other;

(b) positioning a withdrawal string transversely across a point essentially equidistant from the aligned end of the fibers;

(c) fusing a portion of the withdrawal string to at least some of said fibers leaving an unattached portion of said string extending beyond an end of the aligned fibers; and

(d) rolling said aligned fibers along their direction of alignment to form a jelly roll configuration thereby positioning the unattached end of the withdrawal string centrally in the fibrous cylindroidal mass.
