The fibrils of three levels,Which were macrofibrils of several tens micron in diameter,fibrils feW micron and microfibrils about 0.3 micron,were observed simultaneously with banded texture usingpolarized microscope.After annealing,fibrils in different levels relaxed to differentmorphology.Macrofibrils still oriented along shear direction,but fibrils relaxed to helical form,and microfibrils relaxed to waveform therefore the banded texture canbe seen.The smaller the diameter of fibrils was,the more easily the fibrils relaxed.Ori the other hand,the banded texture decoration of annealed unoriented filmsrevealed directly the distribution of directors within and out of domains and thevariation of directors on boundaries.
