Abstract
A nonwoven textile fiber panel, useful, for instance, in manufacturing car truck liners, in which synthetic thermoplastic fibers that vary in fiber length, diameter, denier, and/or density are needle-punched to produce a carpeting material, which can then be directly utilized, or thermoformed to retain a desired shape. The fibers that one desires to show up on the face side of the final product are preferentially driven by the needle barbs of a needle loom through the precursor batt material. This preferential needling can also be enhanced through selection of various needle lengths, needle diameters, and barb spacing configurations.
