Beschreibung
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. 提供了具有入口、定向、合并(205)、和出口(211)区段的挤出模具，该模具可用于生产具有例如分散在其中的定向增强材料(例如，PTFE)的纤维。模具提供具有增强的机械性质和加工性质的纤维。定向区段包括定向通道(203)，其中具有通道进口部的横截面积与通道出口部的横截面积的比在2和45之间。
