FIBROUS STRUCTURES WITH IMPROVED SOFTNESS

摘要

A differential density fibrous structure comprising a structural aspect rati o 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 produc ts comprising such fibrous structures are provided by the present invention. Th e first step in calculating structural aspect ratio is selection of a repeatin g pattern, e.g. two adjacent regions of dispersed within a continuous, high density field C.
