Abstract
Sanitary tissue products employing fibrous structures that exhibit novel tear alone or in combination with tensile properties and methods for making same.
Claims14
A creped sanitary tissue product comprising a through-air-dried fibrous structure comprising a plurality of pulp fibers, wherein the creped sanitary tissue product is void of permanent wet strength, wherein the creped sanitary tissue product exhibits a GM Tear Value as measured according to the Tear Strength Test Method and a GM Tensile Value as measured according to the Dry Tensile Test Method such that the creped sanitary tissue product falls above a line having the following equation:
- y=0.0328x+12.794 graphed on a plot of GM Tear Value (y-axis) to GM Tensile Value (x-axis).
6-9. (canceled)
A dispersible, creped sanitary tissue product comprising a through-air-dried fibrous structure comprising a plurality of pulp fibers, wherein the dispersible, creped sanitary tissue product exhibits a GM Tear Value as measured according to the Tear Strength Test Method and a GM Tensile Value as measured according to the Dry Tensile Test Method such that the dispersible, creped sanitary tissue product falls above a line having the following equation:
- y=0.0328x+12.794 graphed on a plot of GM Tear Value (y-axis) to GM Tensile Value (x-axis).
15-18. (canceled)
A creped, multi-ply sanitary tissue product comprising a through-air-dried fibrous structure comprising a plurality of pulp fibers, wherein the creped, multi-ply sanitary tissue product exhibits a GM Tensile Value of less than 700 g/in as measured according to the Dry Tensile Test Method and wherein the creped, multi-ply sanitary tissue product exhibits a GM Tear Value as measured according to the Tear Test Method and a GM Tensile Value as measured according to the Dry Tensile Test Method such that the creped, multi-ply sanitary tissue product falls above a line having the following equation:
- y=0.0328x+12.794 graphed on a plot of GM Tear Value (y-axis) to GM Tensile Value (x-axis).
A method for making a single- or multi-ply sanitary tissue product 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 is formed;
- and
- b. making a single- or multi-ply sanitary tissue product comprising the 3D patterned fibrous structure ply.
