The invention relates to a ring spinning frame for producing chemical fiber filament core-spun cotton yarn. The ring spinning frame comprises a machine frame. A vertical rough yarn barrel is movably connected with the lower portion of a rough yarn frame. A traction device is arranged at the portion, below the rough yarn barrel, of the machine frame. A pipe barrel and a twisting device are arranged at the portion, below the traction device, of the machine frame. A pipe barrel filament guide hook is arranged at the portion, between the traction device and the pipe barrel, of the machine frame. A vertical fiber filament frame is arranged at the portion, above the rough yarn frame, of the machine frame. A horizontal fiber filament barrel is movably connected with the fiber filament frame. A support connected with the rough yarn frame is arranged in front of the fiber filament barrel. A first fiber filament guide ring is arranged at the position, above the rough yarn frame and corresponding to the fiber filament barrel, of the support. A second fiber filament guide ring is arranged at the portion, below the first fiber filament guide ring, of the support. A fiber filament guide hook is arranged on a rocker arm of the traction device. A fiber filament guide wheel is arranged above an upper front roller of the traction device. The ring spinning frame is reasonable in structural design, convenient to use and capable of making chemical fiber filaments combined with short cotton fibers.
