Why is the structure of polypropylene high strength yarn stable? Mainly due to the following factors:

The structural stability of polypropylene high-strength filament is mainly due to its stable chemical structure, excellent physical properties, optimized production process and wide application environment adaptability. These factors work together to make polypropylene high-strength yarn maintain its stability and durability in various occasions.

1. Stable chemical structure

Polypropylene is the trade name of polypropylene fiber. Isotactic polypropylene with high relative molecular weight is obtained by directional polymerization reaction as spinning raw material.

The chemical structure of polypropylene is stable, the molecular chain is long, and the internal molecular bonding force is strong. This stable chemical structure makes polypropylene fiber able to withstand high temperature and external force, and is not easy to thermal decomposition and oxidation reaction, thus ensuring the structural stability of polypropylene high-strength filament.

Second, excellent physical properties

Polypropylene high strength yarn has high strength and elongation, which makes it able to maintain good morphological stability and mechanical properties when subjected to external forces.

The corrosion resistance of polypropylene is also strong, which can resist a variety of chemical substances and environmental erosion, further enhancing its structural stability.

Third, production process optimization

The production process of polypropylene high strength yarn includes raw material pretreatment, melting rotation, cooling lubrication, stretching and other links.

The raw material pretreatment process improves the quality of the fiber, removes impurities, ensures the color and gloss of the fiber, and improves the strength and elongation.

The melting rotation link makes the fibers uniformly cool and solidify to form filament strips, ensuring the uniformity and consistency of the fibers.

The cooling and lubrication link reduces the surface tension of the filament, reduces the breaking rate, and improves the continuity and stability of the fiber.

The stretching and setting links make the fiber form a certain strength and fineness, which further enhances the structural stability of the polypropylene high-strength yarn.
