Abstract

Fibrous structures that exhibit a Tensile Ratio of less than 1.75 and/or less than 1.49 as measured according to the Tensile Strength Test Method described herein and a Geometric Mean Modulus (GM Modulus) of less than 1402.4 g/cm at 15 g/cm and/or a Machine Direction Modulus (MD Modulus) of less than 1253.4 g/cm at 15 g/cm and/or a Cross Machine Direction Modulus (CD Modulus) of less than 1569.2 g/cm at 15 g/cm, are provided.

Claims (20)

1. An embossed single ply through-air-dried fibrous structure that exhibits a Tensile Ratio of greater than 1.2 as measured according to the Tensile Strength Test Method and a GM Tangent Modulus of greater than 0 g/cm to less than 1077 g/cm at 15 g/cm as measured according to the Modulus Test Method.

2. The embossed single ply through-air-dried fibrous structure according to claim 1 wherein the embossed single ply through-air-dried fibrous structure comprises cellulosic pulp fibers.

3. The embossed single ply through-air-dried fibrous structure according to claim 1 wherein the embossed single ply through-air-dried fibrous structure is a creped, embossed through-air-dried fibrous structure.
