The polypropylene FDY spinning machine is a specialized equipment specifically designed for the production of polypropylene fully oriented drawn filament (FDY), and it holds an important position in the textile industry. This equipment processes polypropylene chips into long filament fibers with excellent physical properties through melt spinning technology, and is widely used in multiple fields such as clothing, industrial fabrics, and decorative materials.

Equipment structure and working principle

The polypropylene FDY spinning machine is mainly composed of core components such as the automatic feeding system, screw extruder, spinning box, metering pump, side blowing device, drawing hot roller, network device, and winding system. The equipment adopts an integrated design, achieving continuous production from raw material input to finished product winding. The screw extruder melts polypropylene chips into a melt, which is precisely measured by a metering pump and then enters the spinning assembly. It is extruded through the spinneret to form primary fibers. Subsequently, the fibers are cooled and solidified by side-blowing air, then stretched and oriented through multi-stage drawing hot rollers. Finally, they are interwoven by a network device and wound into a tube.

Technical features and performance advantages

The polypropylene FDY spinning machine has multiple technical advantages. The equipment adopts high-frequency hot roller heating technology, which features low energy consumption and uniform temperature control. The temperature of the hot roller can be precisely controlled within the range of 80-160℃. The side-blowing air system has a uniform and stable wind speed, ensuring the consistency of the fiber cooling process. The equipment operates stably and reliably with a low failure rate and is easy to operate and maintain. The spinning process speed can reach 2800m/min, with high production efficiency. In addition, the equipment also has a network function, which can produce network filament products, improving the bundling property and processing performance of the fibers.

Product specifications and application fields

The polypropylene FDY spinning machine machine can produce polypropylene filament of different specifications ranging from 100D to 2000D. The products feature high strength, good wear resistance and strong chemical corrosion resistance. Fine denier polypropylene FDY has a soft hand feel and good luster, and is suitable for making sportswear, underwear and other clothing fabrics. Medium and coarse denier products are mainly used in decorative materials such as curtain fabric and sofa fabric. High-strength polypropylene FDY is widely used in industrial fields, such as safety belts, safety nets, industrial sewing threads, fire hoses, etc. The density of polypropylene fiber is only 0.91g/cm, which is the lightest among all chemical fibers. The products made from it are light and comfortable.
