After the development in recent years, the production capacity of polypropylene industrial yarn geotextiles has made rapid development. The equipment level, technology and product quality have basically followed the international standards.

Polypropylene is determined by its structural properties. Under the conditions of using advanced equipment and technology, after several drafting, it can obtain the structure-grade and excellent performance of spinning grade fiber. Through the laying of net, acupuncture consolidation processing of polypropylene industrial yarn geotextiles, fabric uniformity, strength, etc. are improved, all indicators are better than polyester geotextiles, especially in the 100g / m2 gram weight or more (industrial With geotextile mostly in 200g / m2 or more), the advantage is more obvious.

In the case of consolidation by acupuncture, the polypropylene industrial yarn can form a close three-dimensional structure after needling, and its strength and evenness are obviously better than that of the polyester filament. On the other hand, geotextiles are generally not exposed to the sun and air and do not require too high sun-resistance of the material, even though they are subject to long-term exposure to UV radiation. Instead, they are resistant to corrosion Sexual, anti-aging put forward higher requirements. Polypropylene industrial yarn has a very strong acid and alkali resistance, superior to polyester in this regard, it can be used in various geological conditions and the environment, such as landfill anti-leakage, anti-corrosion treatment.
