Abstract: A machine for producing a nonwoven feeds continuous filaments onto two surfaces that form a convergent passage. At least one of the surfaces is moving to drive the continuous filaments through the passage to form the nonwoven web. The continuous filaments have filament portions that are respectively received on the two surfaces to form spaced lateral web parts joined by a central web part formed by the continuous filament portions bridging the convergent passage. A vacuum is applied through the surfaces to assist placement of the filament portions and to direct the web as it emerges from the passage onto a horizontal take-up conveyor.

Abstract: An elastic material for use in an absorbent article is provided. The elastic material contains a crosslinked network formed from a branched block copolymer having a monoalkenyl aromatic midblock positioned between conjugated diene endblocks (e.g., butadiene-styrene-butadiene (“B-S-B”) triblock copolymer). Prior to crosslinking, the branched block copolymers have a relatively low viscosity and thus may be readily formed into a precursor elastic material (e.g., film, strands, web, etc.) that is subsequently crosslinked to achieve the desired elastic and mechanical properties. Crosslinking is typically achieved through the formation of free radicals (unpaired electrons) that link together to form a plurality of carbon-carbon covalent bonds at the conjugated diene endblocks.
