摘要:
A nonwoven substrate. The nonwoven substrate can have a first surface defining a plane of the first surface and a plurality of three-dimensional features extending outwardly from the plane of the first surface. The plurality of three-dimensional features can have a first three-dimensional feature having a first intensive property having a first value and a second three-dimensional feature having the first intensive property having a second value different from the first value. The nonwoven substrate can have an MD Fuzz Value of less than 0.25 mg/cm2 when tested according to the Fuzz Level Test herein.
