The excellent properties of polypropylene high strength yarns are inseparable from the mature production process. With the continuous development of chemical fiber technology, the production process has been continuously optimized, and the product quality has been continuously improved. At the same time, it has been upgraded towards a greener and more efficient direction. Currently, the mainstream production processes of polypropylene high-strength fibers include one-step spinning process and one-step spinning and stretching process. Among them, the one-step spinning process can directly produce products of various colors ranging from 300D to 3000D, with a simple process and high efficiency. 

The typical preparation process mainly includes steps such as raw material mixing, melt spinning, stretching and shaping, and sizing treatment. Firstly, polypropylene pellets are used as the base material and are mixed with nano-scale reinforcing materials in a certain proportion. After adding nucleating agents, they are heated to the molten state and spun to obtain ultra-fine fibers; then, the ultra-fine fibers are twisted using a vortex airflow, and are subsequently sized alternately with various sizing agents and subjected to corona treatment. Finally, they undergo heat setting to obtain high-strength polypropylene filament.
