Abstract:
Thermal compression moldable nonwoven multilayered fibrous batts having substantially uniform density are provided, which are useful, for example, for fabrication of multi-density molded parts, such as multi-density molded vehicle liners. The nonwoven multilayered fibrous batts of uniform density comprising needle-punched first and second (and optionally third and/or fourth) fibrous batt layers formed with different fiber blends, wherein the multilayered batt can be molded into acoustical parts having multi-densities.
