Polypropylene FDY spinning machine is specially used for the production of polypropylene FDY (Fully Drawn Yarn, fully drawn yarn) chemical fiber spinning equipment. Polypropylene FDY products produced by polypropylene FDY spinning machine have excellent physical and chemical properties, and are widely used in clothing, home textiles, industrial textiles and other fields. Using advanced spinning process and technology, by precisely controlling the temperature, pressure, speed and other parameters in the spinning process, the polypropylene raw material melt or colloidal solution is pressed out through the fine hole of the spinneret to form continuous chemical fiber strands. These strands then go through the subsequent drafting, shaping, winding and other processes, and finally get the polypropylene FDY products that meet the quality requirements.

The process flow of polypropylene FDY spinning machine mainly includes raw material preparation, spinning, drawing, shaping, winding and packaging processes. The specific process is as follows:

Raw material preparation: polypropylene raw materials (such as granules, powders, etc.) are mixed, weighed, stirred, etc., to ensure the uniformity and stability of raw materials.

Spinning: The treated raw material melt or colloidal solution is extruded through the screw extruder and pressed out through the fine hole of the spinneret to form a continuous filament bundle.

Drafting: The tow through one or more drafting machine for drafting treatment, so that the strength and elongation of the tow is improved.

Stereotyping: The drawn tow is stereotyped at high temperature so that the macromolecular structure of the fiber is completely oriented and stable.

Winding: the shaped tow is wound to form a polypropylene FDY product that meets the requirements.

Packing: Packaging the wound polypropylene FDY product for convenient transportation and storage.
