Patent ID: 7491770

Claim:
An extensible nonwoven material comprising: a plurality of fibers, the fibers including a polymeric blend, wherein the polymeric blend comprises (a) a first metallocene polypropylene having an average melt temperature T M1 and a melt flow rate MFR 1 ; and (b) a second polypropylene having an average melt temperature T M2 and a melt flow rate MFR 2 ; wherein the weight ratio of the first metallocene polypropylene to the second polypropylene is from about 1:4 to about 4:1 and wherein the polymeric blend has an average melt temperature T Mb of from about 125° C. to about 160° C., a melt flow rate MFR b of from about 15 g/10 minutes to about 35 g/10 minutes wherein: T M1 <T Mb <T M2 , MFR 1 <MFR b <MFR 2 , and MFR 2 /MFR 1 ≧2.0.
