Abstract

The present invention provides a composite nonwoven fabric with a superior combination of extensibility, tensile properties and abrasion resistance. The composite nonwoven fabric (10) comprises at least one layer containing multipolymer fibers, with a plurality of bonds bonding the fibers together to form a coherent extensible nonwoven web (11). This coherent extensible nonwoven web (11) has a Taber surface abrasion value (rubber wheel) of greater than 10 cycles and an elongation at peak load in at least one of the machine direction or the cross-machine direction of at least 70%. A second extensible layer (12) is laminated to this coherent extensible nonwoven web (11).
