ABSTRACT:
A neckable nonwoven web is provided with a central region and two edge regions, the central region being selectively easier to neck than the two edge regions. The nonwoven fibers in the central region have a polymer composition and/or physical properties which differ from the nonwoven fibers in the two edge regions. The selectively easier necking in the central region causes the central region to neck to about the same extent as the two edge regions, which otherwise would experience greater necking than the central region if the starting nonwoven web were completely uniform. Necked nonwoven webs and neck-bonded laminates made using the improved neckable nonwoven web, are also provided.
