A method and associated apparatus for melt extruding a nonwoven web includes providing a plurality of fibers from an extrusion device. The fibers are conveyed through a diverging profile portion of a fiber drawing unit (FDU) that causes the fibers to spread and expand in the machine direction within the FDU. The fibers are then conveyed through a diverging diffusion chamber spaced from the outlet of the FDU to reduce the velocity of the fibers and further spread the fibers in the machine direction. The fibers may be subjected to an applied electrostatic charge in either the diffusion chamber or the FDU. From the outlet of the diffusion chamber, the fibers are laid onto a forming surface as a nonwoven web.

An elastic laminate capable of being rolled for storage and unwound from a roll when needed for use, includes an elastic layer of an array of continuous filament strands with meltblown deposited on the continuous filament strands, and a facing layer bonded to only one side of the elastic layer. The meltblown layer may include an elastic polyolefin-based meltblown polymer having a degree of crystallinity between about 3% and about 40%. The laminate suitably has an inter-layer peel strength of less than about 70 grams per 3 inches cross-directional width at a strain rate of 300 mm/min. Alternatively or additionally, the continuous filament strands and/or the facing layer may include an elastic polyolefin-based meltblown polymer having a degree of crystallinity between about 3% and about 40%. In certain embodiments, the elastic laminate may include an extensible facing layer bonded to an elastic or semi-elastic film layer having a basis weight of about 50 gsm or less, wherein the facing layer includes an elastic polyolefin-based polymer having a degree of crystallinity between about 3% and about 40%.
