Fine multicomponent fiber webs and laminates thereof

A nonwoven laminate comprising:

• a first layer having a first side and a second side, said first layer comprising a nonwoven web of multicomponent meltblown fibers having a first polymeric component and a second polymeric component in distinct zones across the cross-section of the fibers which extend substantially continuously along the length of the fibers, said multicomponent meltblown fibers having an average fiber diameter less than about 7 micrometers;
• a second layer proximate the first side of said first layer, said second layer comprising a nonwoven web of continuous bicomponent spunbond fibers having an average fiber diameter greater than about 10 micrometers,
• a third layer proximate the second side of said first layer, said third layer comprising a nonwoven web of continuous bicomponent spunbond fibers having an average fiber diameter greater tan about 10 micrometers;
• and
• wherein said second and third spunbond layers are extensible and further wherein the first polymeric component of said multicomponent meltblown fiber web comprises an elastic polyolefin and wherein said second component of the multicomponent meltblown fiber web comprises an elastic polymer and wherein said layers are bonded together to form a multilayer laminate.
