| Zusammenfassung: | The present invention relates to meltblown fiber webs and, in particular, to multicomponent meltblown fiber webs and laminates thereof.
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. |
