Sanitary tissue products employing 3D patterned fibrous structure plies having a surface comprising a novel three-dimensional (3D) pattern and which exhibit novel cushiness as evidenced by compressibility of the fibrous structures and/or sanitary tissue products, novel flexibility as evidenced by plate stiffness of the fibrous structures and/or sanitary tissue products, and/or surface smoothness as evidenced by slip stick coefficient of friction of the fibrous structures and/or sanitary tissue products, and methods for making same, are provided. The sanitary tissue product may comprise a 3D patterned fibrous structure ply having a surface comprising a 3D pattern comprising a first series of line elements that are oriented at an angle of less than 200 with respect to the cross-machine direction of the 3D patterned fibrous structure ply. The sanitary tissue product may exhibit a Compressibility of greater than 36 mils/(log(g/in2)) as measured according to the Stack Compressibility Test Method. L'invention concerne des produits de papier hygiénique utilisant des feuilles de structure fibreuse présentant des dessins en 3D présentant une surface comprenant des dessins en trois dimensions (3D) innovants de sorte que les structures fibreuses présentant des dessins en 3D et/ou des produits de papier hygiénique utilisant les structures fibreuses présentent un moelleux innovant grâce à la compressibilité des structures fibreuses et/ou des produits de papier hygiénique, une flexibilité innovante grâce à la rigidité à plat des structures fibreuses et/ou des produits de papier hygiénique et/ou un aspect lisse de surface grâce au coefficient de friction d'adhérence/de glissement des structures fibreuses et/ou des produits de papier hygiénique, et des procédés de fabrication associés.
