PROBLEM TO BE SOLVED: To obtain combined nylon filament yarns for carpets, excellent in bulkiness, having favorable feed and gloss, and affording colored patterns with clear-cut contrast. SOLUTION: The combined nylon filament yarns for carpets are such ones as to be interlaced with three kinds of triangular cross-section bulky nylon filaments comprising acid dye-dyeable nylon filaments, basic dye-dyeable nylon filaments and nylon filaments sparingly dyeable with both acid dye and basic dye, wherein at least one of the above three kinds of triangular cross-section bulky nylon filaments is wet-spun nylon filaments with scaled morphological surface.
