A method of making a cloth-like composite laminate is provided. The method includes the steps of air laying a continuous layer of three-dimensional cellulosic fibers one side of a layer of nonwoven material; applying to the continuous layer of three-dimensional cellulosic fibers and the nonwoven material layer a latex adhesive containing a wetting agent; and drying the latex adhesive and wetting agent to bind the layer of cellulosic fibers to the nonwoven material layer to form a cloth-like composite laminate having a continuous layer of three-dimensional cellulosic fibers bound to one side of the nonwoven material layer.
