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. A multi-ply fibrous structure comprising:
a. a first ply comprising: a plurality of wood pulp fibers and a plurality of meltblown filaments selected from the group consisting of polyester meltblown filaments, nylon meltblown filaments, polyolefin meltblown filaments, biodegradable meltblown filaments, compostable meltblown filaments, and mixtures thereof, wherein the plurality of meltblown filaments exhibit a length of greater than or equal to 5.08 cm, wherein the first ply comprises a coform layer, wherein a first portion of the plurality of wood pulp fibers are in the form of a first wet laid fibrous structure and a second portion of the plurality of wood pulp fibers are commingled with a portion of the plurality of meltblown filaments in the form of a coform structure, wherein the plurality of meltblown filaments are spun from a die and directly laid on top of the first wet laid fibrous structure; and
b. a second ply comprising a second wet laid fibrous structure comprising a plurality of wood pulp fibers associated with the first ply such that the multi-ply fibrous structure exhibits a Low Load Wet Resiliency of greater than 0.95 as measured according to the Wet and Dry Compressive Modulus Test Methods and a Bending Modulus of less than 10.00 [(mg*cm·g)/mils 3 ] as measured according to the Bending Modulus Test Method.

2. The multi-ply fibrous structure according to claim 1 wherein at least one of the plurality of meltblown filaments is selected from the group consisting of polyolefin meltblown filaments, polylactic acid meltblown filaments, polyhydroxyalkanoate meltblown filaments, polyesteramide meltblown filaments, polycaprolactone meltblown filaments, and mixtures thereof.

3. The multi-ply fibrous structure according to claim 2 wherein the thermoplastic polymer is a polyolefin selected from the group consisting of: polypropylene, polyethylene, and mixtures thereof.

4. The multi-ply fibrous structure according to claim 1 wherein the multi-ply fibrous structure further exhibits a TS7 of less than 17.0 dB V 2 rms as measured according to the Emtec Test Method.

5. The multi-ply fibrous structure according to claim 1 wherein at least one of the plurality of meltblown filaments is selected from the group consisting of biodegradable meltblown filaments, compostable meltblown filaments and mixtures thereof.

6. The multi-ply fibrous structure according to claim 1 wherein at least one of the plurality of meltblown filaments is selected from the group consisting of polylactic acid meltblown filaments, polyhydroxyalkanoate meltblown filaments, polyesteramide meltblown filaments, polycaprolactone meltblown filaments, and mixtures thereof.

7. The multi-ply fibrous structure according to claim 1 wherein at least one of the plurality of meltblown filaments is a polylactic acid meltblown filament.

8. The multi-ply fibrous structure according to claim 1 wherein at least one of the plurality of meltblown filaments is a polyhydroxyalkanoate meltblown filament.

9. A multi-ply sanitary tissue product comprising a multi-ply fibrous structure according to claim 1 .
