ABSTRACT:
A method of making a flat cloth-like composite laminate is produced. The method includes the steps of inserting a scrim coated with a thermoplastic binder between two nonwoven layers each of the nonwoven layers being formed of three-dimensional cellulosic fibers bound with a latex adhesive; heating the scrim and the two nonwoven layers to a temperature sufficient to activate the thermoplastic binder while maintaining equal tension on the scrim and the two nonwoven layers; and pressing the scrim and the two nonwoven layers together to form a flat cloth-like composite laminate having the nonwoven layers of cellulosic fibers adhered to opposite sides of the scrim. The surface of each nonwoven layer is planar and interrupted by the scrim.
