The polypropylene FDY spinning machine launched by Changzhou Fubon Chemical Fiber Machinery Factory Technical is based on the core design concept of melt spinning. It integrates functions such as extrusion, spinning, cooling, stretching, and winding to form a continuous production line. The equipment uses polypropylene pellets as raw materials, which are dried and then enter a long-length screw extruder. Through zone heating and shear action, the solid pellets are transformed into uniformly flowing molten material. Combined with a high-precision melt filter, it can effectively remove impurities, providing a basic condition for stable spinning. 

From a technical perspective, the equipment mainly relies on controllable melting, precise measurement, uniform cooling, and multi-stage stretching as its core technologies. By adjusting parameters, it can produce polypropylene filament yarns of different counts and different strength grades. Whether it is for civilian sewing thread, yarn wrapping, or web materials, or for industrial use such as geotextiles, ropes, and safety protection threads, all can achieve stable production by adjusting the process. The precise control of cooling and stretching parameters helps enhance the mechanical properties of the fibers, making the finished products have features such as light weight, resistance to acids and alkalis, and good elasticity, thereby expanding the downstream application scenarios. 

In the cooling and forming process, the equipment is equipped with a uniform and stable side blowing air system. By adjusting the wind speed and temperature, the molten stream can be uniformly cooled, reducing the unevenness of the yarn. The cooled and solidified filament then enters the drawing zone, where it is stretched and thermally shaped through the cooperation of multiple drawing rollers to ensure the stability of the internal structure of the fiber.
