Zusammenfassung:	PURPOSE:To enable a stable operation and efficiently obtain a fine denier filament yarn of high quality due to the stable operation by using the mirror- finished first roller and the second roller in which mirror surface areas and stain surface areas are alternately arranged in the axial direction and carrying out direct spinning and drawing at a high speed. CONSTITUTION:The objective direct spinning and drawing of a synthetic fiber is carried out by carrying out drawing using the mirrorfinished first roller 2 and the second roller 4 in which mirror surface areas 6 and stain surface areas 7 are alternately arranged in the axial direction and subsequently winding multiseparated single filaments at >=4000m/min. In addition, mirror finish is carried out, e.g. by hard chrome plating and the stain surface areas 7 are formed, e.g. by sandblasting the part to be processed and then carrying out hard chrome plating. In addition thereto, a polyester is preferably used as the synthetic fiber.
