Abstract:
A process for making a necked nonwoven material having improved cross-directional uniformity, comprising the steps of:providing a nonwoven web having a central region and two edge regions; passing the nonwoven web through a first nip having a first average surface velocity, and a second nip having a second average surface velocity higher than the first average surface velocity; necking the nonwoven web between the first and second nips; and selectively increasing the necking in the central region of the nonwoven web relative to the two edge regions; wherein the step of selectively increasing the necking in the central region comprises the step of reducing necking resistance in the central region relative to the two edge regions.
