PROBLEM TO BE SOLVED: To provide an aramid filament fiber structure with excellent dye-affinity, which is dyeable by piece-dyeing which is capable of various color development by using ordinary dyeing facilities, particularly provide an aramide filament fiber structure with excellent dye-affinity even when the aramide filament fiber is para-aramide filament fibers. SOLUTION: There is provided the method for dyeing the aramide filament fiber structure containing aramide filament fibers subjected to a fluid processing. Para-aramide filament fibers are preferred as aramide filament fibers. The fluid processing of the aramide filament fibers is preferably carried out by flowing aramide filament fibers with a single yarn fineness of 0.1-10 dtex, a total fineness of 10-7,000 dtex, and a twist factor of 0-10,000 in a fluid injection nozzle with an over feeding ratio of 0-15% while feeding fluid with a feed pressure of 0.29-1 MPa to the fluid injection nozzle.
