Differential Cellulose Content Articles

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.

What is claimed is: 
     
         1 . A fibrous structure comprising a plurality of fibrous elements, wherein the fibrous structure exhibits a thickness and wherein the fibrous structure exhibits a cellulose content that varies throughout the thickness of the fibrous structure such that the cellulose content of a first portion of the fibrous structure is from 0% to less than 40% by weight of the fibrous elements in the first portion, the cellulose content of a second portion of the fibrous structure different from the first portion is from 40% to less than 95% by weight of the fibrous elements in the second portion, and the cellulose content of a third portion of the fibrous structure different from the first and second portions is 95% to 100% by weight of the fibrous elements in the third portion, and wherein at least the second portion comprises a mixture of filaments and fibers. 
     
     
         2 . The fibrous structure according to  claim 1  wherein the first, second, and third portions are visually discernible from each other. 
     
     
         3 . The fibrous structure according to  claim 1  wherein the fibers and filaments of the second portion are commingled together. 
     
     
         4 . The fibrous structure according to  claim 1  wherein the fibers of the second portion comprise pulp fibers. 
     
     
         5 . The fibrous structure according to  claim 1  wherein the filaments of the second portion comprises a thermoplastic polymer. 
     
     
         6 . The fibrous structure according to  claim 5  wherein the thermoplastic polymer comprises a polyolefin. 
     
     
         7 . The fibrous structure according to  claim 1  wherein the second portion comprises a co-formed fibrous structure. 
     
     
         8 . The fibrous structure according to  claim 1  wherein the first portion comprises a meltblown fibrous structure. 
     
     
         9 . The fibrous structure according to  claim 8  wherein the meltblown fibrous structure comprises a plurality of meltblown filaments. 
     
     
         10 . The fibrous structure according to  claim 9  wherein at least one of the meltblown filaments comprises a thermoplastic polymer. 
     
     
         11 . The fibrous structure according to  claim 10  wherein the thermoplastic polymer comprises a polyolefin. 
     
     
         12 . The fibrous structure according to  claim 11  wherein the polyolefin comprises polypropylene. 
     
     
         13 . The fibrous structure according to  claim 1  wherein the third portion comprises a wet-laid fibrous structure. 
     
     
         14 . The fibrous structure according to  claim 13  wherein the wet-laid fibrous structure comprises a textured wet-laid fibrous structure. 
     
     
         15 . The fibrous structure according to  claim 14  wherein the textured wet-laid fibrous structure comprises a three-dimensional patterned wet-laid fibrous structure. 
     
     
         16 . The fibrous structure according to  claim 13  wherein the wet-laid fibrous structure comprises a through-aid-dried fibrous structure. 
     
     
         17 . The fibrous structure according to  claim 16  wherein the through-air-dried fibrous structure comprises a creped through-air-dried fibrous structure. 
     
     
         18 . The fibrous structure according to claim  16 wherein the through-air-dried fibrous structure comprises an uncreped through-air-dried fibrous structure. 
     
     
         19 . The fibrous structure according to  claim 13  wherein the wet-laid fibrous structure comprises a fabric-creped fibrous structure. 
     
     
         20 . The fibrous structure according to  claim 13  wherein the wet-laid fibrous structure comprises a belt-creped fibrous structure.
