Document Type and Number:
WIPO Patent Application WO2000037723
Kind Code:
A3
Abstract:
The present invention provides multicomponent fine fiber webs and multilayer laminates thereof having an average fiber diameter less than about 7 micrometers and comprising a first olefin polymer component and a second distinct polymer component such as an amorphous polyolefin or polyamide. Multilayer laminates incorporating the fine multicomponent fiber webs are also provided such as, for example, spunbond/meltblown/spunbond laminates or spunbond/meltblown/meltblown/spunbond laminates. The fine multicomponent fiber webs and laminates thereof provide laminates having excellent softness, peel strength and/or controlled permeability.
