Zusammenfassung:Multilayer meltblown composites, articles made therefrom, and methods for making same. One method can include meltblowing a first material to form a first meltblown layer; meltblowing a second material to form a second meltblown layer; and meltblowing a third material to form a third meltblown layer, wherein each material is the same or different, each material includes at least one resin having a MFR of about 2,000 dg/min or less, as measured by ASTM D1238, 2.16 kg, 230°C, and at least one of the first, second, and third materials comprises an elastomer having a recovery of at least 70% after 100% deformation, as determined by ASTM D412.
