Abstract

A method of making a resilient tampon includes the steps of providing binder fibers having an average fiber length of at least 35 mm; combining the binder fibers to form a loose fleece; activating the binder fibers; and compressing a portion of the loose fleece into a pledget after activating the binder fibers. A resilient tampon includes 70 wt % to 95 wt % absorbent fibers and 5 wt % to 30 wt % bicomponent binder fibers. The binder fibers have an average fiber length greater than 35 mm.

Claims (20)

1. A resilient tampon comprising:

a. 70 wt % to 95 wt % absorbent fibers; and

b. 5 wt % to 30 wt % binder fibers, wherein the binder fibers have an average fiber length of greater than 35 mm;

wherein the absorbent fibers and the binder fibers are substantially aligned.

2. The resilient tampon of claim 1 wherein the absorbent fibers are viscose rayon.

3. The resilient tampon of claim 2 wherein the absorbent fibers comprise 80 wt % to 90 wt %.

4. The resilient tampon of claim 1 wherein the absorbent fibers are trilobal viscose rayon.

5. The resilient tampon of claim 4 wherein the absorbent fibers comprise 80 wt % to 90 wt %.

6. The resilient tampon of claim 1 wherein the binder fibers are bicomponent fibers.

7. The resilient tampon of claim 6 wherein the bicomponent fibers comprise 10 wt % to 20 wt %.

8. The resilient tampon of claim 6 wherein the bicomponent fibers have a core made of polypropylene and a sheath made of modified polyethylene wherein the sheath surrounds the core.

9. A resilient tampon comprising,

a. 70 wt % to 95 wt % absorbent fibers; and

b. 5 wt % to 30 wt % bicomponent binder fibers, wherein the binder fibers have an average fiber length greater than 35 mm;

wherein the absorbent fibers and the bicomponent binder fibers are substantially aligned.

10. The resilient tampon of claim 9 wherein the absorbent fibers are viscose rayon and comprise 85 wt % to 90 wt %.

11. The resilient tampon of claim 9 wherein the bicomponent binder fibers comprise 10 wt % to 15 wt % and have a core made of polypropylene and a sheath made of modified polyethylene wherein the sheath surrounds the core.

12. The resilient tampon of claim 9 wherein

a. the absorbent fibers are trilobal viscose rayon and comprise 80 wt % to 90 wt %; and

the bicomponent fibers comprise 10 wt % to 20 wt % and have a core made of polypropylene and a sheath made of modified polyethylene wherein the sheath surrounds the core.
