A differential density fibrous structure comprising a structural aspect ratio of greater than 1.5 wherein the fibrous structure exhibits a modulus to tensile strength ratio as defined below: Formula (I), wherein ARD90M is the modulus measured perpendicular to the direction the structural aspect ratio is measured; and ARD90T is the tensile strength measured perpendicular to the direction the structural aspect ratio is measured. Said fibrous structures exhibiting improved softness and single- or multi-ply sanitary tissue products comprising such fibrous structures are provided by the present invention. The first step in calculating structural aspect ratio is selection of a repeating pattern, e.g. two adjacent regions of dispersed within a continuous, high density field C.

La présente invention concerne des structures fibreuses d'une plus grande douceur ainsi que des articles hygiéniques mono- ou multicouches contenant de telles fibres.
