Abstract
Nonwoven webs prepared from a blend of polymer and a migrating internal additive are heat treated only in selected regions to cause surface migration of the additive in those regions. The nonwoven webs have a desired property attributed to the additive in the selective regions. Regions surrounding the selected regions are not heat treated, and are either devoid of the desired property, or manifest the property to a lesser extent than in the heat treated regions.
