The effect of drawing speed on several properties of acrylic fibers has been examined. The acrylic fibers were prepared by the wet‐spinning process. The coagulation bath contained 30–70% DMF and was held at a temperature varying from 10–45°C. From x‐ray diffraction measurement, the orientation of finished fibers increased with an increase in drawing speed, and became constant when the drawing speed exceeded 40–50 m/min. The tenacity and stability to repetitive deformation also increased to a drawing speed of 40–50 m/min, but then decreased. The spinning conditions (spin‐bath composition and temperature) influenced the most attainable properties of the finished fibers. The results are discussed from the point of view of structural changes in fibers during drawing.
