ABSTRACT:
Self-bonded, balanced nonwoven fibrous fabrics having fibers uniaxially oriented and junction points of biaxially oriented film tissue and fibers in the plane of the fabric, the fibers being primarily oriented in the machine direction with the biaxially oriented film tissue being oriented in the cross direction. The nonwoven fabrics are produced by extruding a molten polymer radially from a circular die, quenching and then drawing the extrudate.
