发明名称 METHOD FOR FORMING LAMINATE NONWOVEN FABRIC
摘要 A method for creating a nonwoven laminate fabric with three laminated layers, with top and bottom layers of thin veneer and a center layer of pulp, resulting in a laminate fabric with particular utility as a flushable wipe. Figure 1 illustrates a hydroentangled nonwoven layer (20) provided on a moving support (22). A second nonwoven layer (24) is overlaid on top of first layer (20) and a third nonwoven layer (26) overlaid on top of second layer (24). Support (22) with the three layers thereon is then conveyed under manifold (28). For the utility in making flushable wipes, unentangled regions (52) between lines of entanglement (50) result in a laminate fabric that has a sufficient wet strength and can disentangle under normal shear stresses present in a sewer system so as to be flushable.
