Glass Fiber Yarn, due to its unique properties, is widely used in indoor and outdoor optical cables (optical cables). As a non-metallic reinforcing material, it has gradually become an important choice in the industry. Before its advent, the flexible non-metallic reinforcing parts of optical cables were mainly Aramid Yarn. Aramid, as a high-performance material, not only has significant applications in the field of optical cables but is also widely used in high-end fields such as national defense and aerospace. However, aramid yarn is relatively expensive, while glass fiber reinforced yarn can to some extent replace aramid, providing a more cost-effective solution for optical cable production.
The manufacturing process of glass fiber reinforced yarn involves using alkali-free glass fiber (E-glass) as the main body, uniformly coating polymer and subjecting it to heating treatment. Compared with the easily dispersible glass fiber raw yarn, the coated glass fiber reinforced yarn has better processing performance and comprehensive performance. It not only has certain strength and modulus, but also has softness and lightness. Its temperature resistance, corrosion resistance and anti-aging performance enable it to adapt to the complex and changeable optical cable usage environment, making it a non-metallic strength member with both performance and economy.
In terms of application, glass fiber reinforced yarn, as an excellent flexible optical cable bearing element, is often placed in parallel in the production of indoor fiber optic cables. The process is simple and can well protect the optical fiber. In the production of outdoor fiber optic cables, the use of glass fiber reinforcing yarn is even greater. It is usually spun and wrapped over the core of the cable by twisting the cage, and the tension is strictly controlled to ensure the overall mechanical properties of the cable. Water-blocking glass yarn can also play a dual role of tensile resistance and water blocking in optical cables at the same time. Its unique puncture property can also effectively prevent rats (rodent protection), further enhancing the service life and stability of optical cables.
With its comprehensive advantages such as moderate strength, good flexibility, light weight and low price, it has become an indispensable important material in the manufacture of optical fibers and cables, and has also been gradually applied more in power cables (power cables).
