Abstract
High twist fibers are produced in a spin/quench/twist process directly from a modified spinneret. The spinneret consists of capillaries that are installed in highly elongated inserts which are surrounded by heat deflecting shields surrounded by an annular concentric orifice supplied with a fluid (air or steam preferred) that simultaneously quenches and twists the emerging filaments as they exit the capillary quench/torque jet.
