ABSTRACT:
A thermoplastic nonwoven web is softened by stretching the web in the cross-machine direction, stretching the web in the machine direction, and shearing the surfaces of the web relative to each other. The resulting web has increased flexibility and increased surface nap which correlates with increased perceived softness.
