Abstract

Sanitary tissue products that exhibit novel free fiber numbers compared to known sanitary tissue products as measured according to the Free Fiber Test Method described herein, and methods for making same, are provided.

Claims (21)

1. A sanitary tissue product comprising a 3D patterned fibrous structure ply comprising a plurality of pulp fibers, wherein the sanitary tissue product exhibits a Free Fiber number of greater than 26 as measured according to the Free Fiber Test Method.

2. The sanitary tissue product according to claim 1 wherein the sanitary tissue product exhibits a lint of less than 15 as measured according to the Lint Test Method.

3. The sanitary tissue product according to claim 1 wherein the pulp fibers comprise wood pulp fibers.

4. The sanitary tissue product according to claim 1 wherein the pulp fibers comprise non-wood pulp fibers.

5. The sanitary tissue product according to claim 1 wherein the 3D patterned fibrous structure ply comprises an embossed 3D patterned fibrous structure ply.

6. The sanitary tissue product according to claim 1 wherein the 3D patterned fibrous structure ply comprises a through-air-dried fibrous structure ply.

7. The sanitary tissue product according to claim 1 wherein the 3D patterned fibrous structure ply is a creped through-air-dried fibrous structure ply.

8. The sanitary tissue product according to claim 1 wherein the 3D patterned fibrous structure ply is an uncreped through-air-dried fibrous structure ply.

9. The sanitary tissue product according to claim 1 wherein the 3D patterned fibrous structure ply is a fabric creped fibrous structure ply.

10. The sanitary tissue product according to claim 1 wherein the 3D patterned fibrous structure ply is a belt creped fibrous structure ply.

11. The sanitary tissue product according to claim 1 wherein the sanitary tissue product comprises a conventional wet-pressed fibrous structure ply.

12. The sanitary tissue product according to claim 1 wherein the sanitary tissue product comprises a consumer user side that exhibits the Free Fiber number.

13. The sanitary tissue product according to claim 1 wherein the sanitary tissue product exhibits a Free Fiber number of 27 or greater as measured according to the Free Fiber Test Method.

14. The sanitary tissue product according to claim 1 wherein the sanitary tissue product exhibits a Free Fiber number of 29 or greater as measured according to the Free Fiber Test Method.

15. The sanitary tissue product according to claim 1 wherein the sanitary tissue product exhibits a Free Fiber number of 30 or greater as measured according to the Free Fiber Test Method.

16. The sanitary tissue product according to claim 1 wherein the sanitary tissue product exhibits a Free Fiber number of 35 or greater as measured according to the Free Fiber Test Method.

17. The sanitary tissue product according to claim 1 wherein the sanitary tissue product exhibits a lint of less than 10 as measured according to the Lint Test Method.

18. The sanitary tissue product according to claim 1 wherein the sanitary tissue product exhibits a lint of less than 9 as measured according to the Lint Test Method.

19. A method for making a single- or multi-ply sanitary tissue product, the method comprising the steps of:

a. contacting a patterned molding member with a fibrous structure comprising a plurality of pulp fibers such that a 3D patterned fibrous structure ply that exhibits a Free Fiber number of greater than 26 as measured according to the Free Fiber Test Method is formed; and

b. making a single- or multi-ply sanitary tissue product according to the present invention comprising the 3D patterned fibrous structure ply.
