摘要:
A forming belt for use in making a nonwoven substrate. The forming belt includes a first surface defining a plane of the first surface and an axis parallel to a longitudinal direction corresponding to a machine direction when in use. A plurality of discrete belt patterns can be ordered in sequential relationship with respect to the longitudinal direction. At least a majority of the plurality of discrete belt patterns can include a discrete belt pattern overall area, a first forming zone having a first pattern of three-dimensional raised elements extending outwardly from the plane of the first surface and a second forming zone having a second pattern of three-dimensional raised elements extending outwardly from the plane of the first surface. The first forming zone can have a first air permeability value and the second forming zone can have a second air permeability value. The first air permeability value can be different from the second air permeability value.
