发明名称 Needlepunched nonwoven with centrally-located binder
摘要 The present invention concerns a process for forming a wearable and functional fabric from a composite material comprising a nonwoven face layer containing a plurality of fibers, and at least one thermoplastic binder layer disposed underneath. The fibers are initially arranged in a generally planar web and subsequently needlepunched through at least one binder layer. The fiber layers can also be placed on both sides of one or more centrally-located binder layers, and further reinforced with scrims. In an innovative aspect of the invention, the composite is heated under low and uniform pressure to remove thermal stresses, resulting in at a least one relatively smooth face that can be coated to form a wearable fabric, e.g., artificial leather, odor absorbing fabric, and the like.
