Strong fibrous structures
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.
1. A multi-ply fibrous structure comprising:
a. a first ply comprising: a plurality of wood pulp fibers and a plurality of thermoplastic meltblown filaments selected from the group consisting of polyester thermoplastic meltblown filaments, nylon thermoplastic meltblown filaments, polyolefin thermoplastic meltblown filaments, biodegradable thermoplastic meltblown filaments, compostable thermoplastic meltblown filaments, and mixtures thereof, wherein the plurality of thermoplastic meltblown filaments exhibit a length of greater than or equal to 5.08 cm, 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 together with a portion of the thermoplastic meltblown filaments in the form of a coform fibrous structure; and
b. a second ply comprising a second wet laid fibrous structure comprising a plurality of wood pulp fibers, wherein the portion of the thermoplastic meltblown filaments in the form of the coform fibrous structure of the first ply are spun from a die and directly laid on top of the second wet laid fibrous structure such that the multi-ply fibrous structure exhibits a Wet/Dry CD TEA of at least 1.300 as measured according to the Wet and Dry Tensile Strength Test Methods.
