Abstract

Articles, such as sanitary tissue products, including fibrous structures, and more particularly articles including fibrous structures having a plurality of fibrous elements wherein the article exhibits differential cellulose content throughout the thickness of the article and methods for making same are provided.

First claim

What is claimed is:

1. An article comprising:
a. a first ply comprising a first plurality of wood pulp fibers and a plurality of spun polyvinyl alcohol filaments, wherein a first portion of the first plurality of wood pulp fibers are in the form of a first wet laid fibrous structure and a second portion of the first plurality of wood pulp fibers are commingled together with at least a portion of the plurality of spun polyvinyl alcohol filaments in the form of a coform fibrous structure, wherein the portion of the plurality of spun polyvinyl alcohol filaments;
b. a second ply comprising a second wet laid fibrous structure comprising a second plurality of wood pulp fibers, wherein the second wet laid fibrous structure is bonded to the first wet laid fibrous structure; and
wherein the article is void of a hydroentangled fibrous web.

2. The article according to claim 1 wherein at least one the first and second plurality of wood pulp fibers are selected from the group consisting of: northern softwood kraft pulp fibers, southern softwood kraft pulp fibers, northern hardwood pulp fibers, tropical hardwood pulp fibers, and mixtures thereof.
