Zusammenfassung:	Provided are extrusion dies having entrance, orientation, merging (205), and exit (211) sections, which dies may be used to produce fibers having, e.g., oriented reinforcement materials (e.g., PTFE) dispersed within. The dies provide fibers having enhanced mechanical and processing properties. The orientation section comprises orientation channels (203) wherein a ratio of a cross-sectional area having of the channel inlet to a cross-sectional area of the channel outlet is between 2 and 45.
