Abstract (en)

[origin: WO9937839A1] The present invention provides a method for making a strong and soft nonwoven web. A neckable nonwoven web is fed in a first direction. A tensioning force is applied to the neckable nonwoven web to neck the nonwoven web. Optionally, the necked nonwoven web may be subjected to mechanical stabilization after necking to provide a stabilized extensible necked nonwoven web. The nonwoven web is then subjected to incremental stretching in a direction perpendicular to the first direction to provide a strong and soft nonwoven web.
