摘要:
Disclosed is a multilayer fabric and a method of forming a multilayer fabric comprising one or more facing layers and one or more elastic layers adjacent to or sandwiched there between, the one or more facing layers comprising a polypropylene; and a propylene-α-olefin elastomer having and an MFR of less than 80 dg/min; wherein the facing layer is extensible and non-elastic and has a Handle-O-Meter value of less than 60 g and a 1% Secant Flexural Modulus of less than 1000 MPa. In certain embodiments, polyethylenes are absent from the facing layer(s).
