Abstract

See full text

Necked nonwoven webs having improved cross-directional uniformity are made by a process which includes the step (prior to neck stretching) of corrugating the nonwoven web to reduce its width from an initial width A to a reduced corrugated width B. The cross-directional uniformity is optimized as the corrugated width B approaches the ultimate width C of the necked nonwoven web.
