The invention claimed is: 1. A method of making an automotive headliner, door panel or interior trim part, comprising: selecting a fiber yarn, bundle, or roving of natural fiber selected from a group consisting of kenaf, jute, sisal, hemp and mixtures thereof; feeding said fiber yarn, bundle, or roving into a chopping device; chopping said fiber yarn, bundle, or roving into fiber segments having a length of about 0.1 inch to about 10 inches; texturizing said fiber segments by passing said fiber segments through a texturizing gun at a rate of about 1 to about 15 meters/minute and injecting a fluid at a pressure of about 0.1 to about 7.0 bar; simultaneously introducing said fiber segments at a weight percentage of about 35 to about 85 percent and a binder at a weight percentage of about 15 to about 65 percent into a mold; and molding said fiber segments and binder into an automotive headliner, door panel or interior trim part. 2. The method of claim 1, wherein said binder is a thermoset resin. 3. The method of claim 1, wherein said binder is a thermoplastic resin. 4. The method of claim 1, further including selecting said binder from a group consisting of solid resin powders, solid resin fibers, liquid resin, foamable resin and mixtures thereof. 5. The method of claim 1, further including selecting said binder from a group of resinous materials consisting of acrylic, urethane, epoxy, vinyl acetate, epoxy-acrylic hybrids, and any mixtures thereof. 6.
