Patent ID: 10062371

Abstract:
A nonwoven composite containing a first nonwoven layer having a plurality of primary fibers and optionally binder fibers, a thermoplastic film comprising a thermoplastic polymer having an elongation at break greater than 300% and a max softening point (thermomechanical analysis end point) between 150° C. and 200° C. as tested according to ASTM E2347-04 and containing a plurality of holes and an air flow resistance great than 1,500 Rayls. A second nonwoven layer having a plurality of bulking fibers and optionally binder fibers. The thermoplastic film is adjacent the bottom surface of the first nonwoven layer and the top surface of the second nonwoven layer and sandwiched between the first and second nonwoven layers. At least a portion of the primary fibers from the first nonwoven layer are located in the holes of the thermoplastic film and within the second nonwoven layer.
