This study proposes a visualization technique with image analyzing system in order to quantitatively analyze the migration behaviour of staple fibers in yarn. The 3-D plots of constituent fibers were obtained and rotational frequencies of the fibers along the yarn axis were measured using the fast fourier transformation (FFT). The results were experimentally identified by the accumulation of the rotational angles of fibers. As migration parameters, the mean fiber position, root mean square (rms) deviation, migration intensity and migration frequency, were calculated from experimental measurements and compared with those of the idealized yarn structure.
