抄録

The fiber with gradually changing diameter was fabricated by changing the draw ratio continuously, that is, by changing the take-up speed of melt spinning, laser drawing, and heater drawing processes. The diameter profiles of resultant fibers were monitored and compared each other. As the results, the laser drawing shows the best diameter responsiveness among the three. For the case, the diameter changing rate increased with the increase of fiber acceleration rate up to 6.0 m/s2. Moreover, it can make the fiber whose diameter gradually changed about 40% within 8 cm range for the minimum case. The diameter profile was determinded by not only the draw ratio profile but also the start/end draw ratios. The lower drawing stress change tends to improve the responsiveness, and the minimum response length for laser drawing was obtained for the draw ratio decreasing case.
