of the Invention, A nonwoven textile fiber panel useful, for instance, in, manufacturing car trunk 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.
