A method for preparing profiled fibers with low lousiness rate by a polyester FDY process is provided, when preparing profiled fibers by the FDY process, during the operation of a yarn path, the horizontal and longitudinal positions of wire guide ceramic pieces on the pre-entangling wire guide frame are adjusted to maintain vertical alignment of the filament bundle in the pre-entangling device and achieve optimal jitter effect, to prepare profiled fibers with a low lousiness rate; when the profiled fibers are triangular profiled fibers, the lousiness rate is 0.35-0.65%; when the profiled fibers are trilobal profiled fibers, the lousiness rate is 0.85-1.25%; when the profiled fibers are flat profiled fibers, the lousiness rate is 0.5-0.85%.
