Analysis of Fiber Drawing in Wet Spinning for Surface Roughness

The drawing process behavior was investigated with focus on fiber stretching speed (spinning acceleration) to improve luster quality of fibers. Wet spinning method has a limitation low at high speed. It determined that (1) could be evaluated by arithmetic average ( RΔa ) fibers, which indicated the roughness, and (2) roughness related acceleration through analysis . Spinning measured chasing markers were used tie Regardless length bath, fibers mainly stretched during first stage. Therefore, multistep used. In case where ratio 220% one-step, 10.1°; however multi-step (1 st 2 nd ratios 148.3%), decreased 8.3°. enabled reduction in preventing sudden change stress. addition, temperatures improved roughness. At temperatures, despite because easier stretch than temperatures.
