Manufacturing technology and application of glass fiber reinforced yarns

Manufacturing Technology and Application of Glass Fiber Reinforced Yarns
Glass fiber reinforcing yarn can be used as a non-metallic reinforcing material for fiber optic cables due to its unique properties and is widely used in indoor and outdoor fiber optic cables.
Glass fiber reinforcing yarn is a flexible non-metallic reinforcing material different from aramid yarn. Before the emergence of glass fiber reinforcing yarns, aramid yarns were mainly used as flexible non-metallic reinforcing materials for fiber optic cables. Aramid is not only an important reinforcing material in the field of fiber optic cables, but also a valuable material in the fields of defense, military and aerospace.
Glass fiber reinforcing yarn has certain strength and modulus, flexibility and portability, and the price is lower than that of aramid yarn, which can be used as a substitute for aramid yarn in many aspects.

Manufacturing technology of glass fiber yarn
Glass fiber reinforced yarn is also structurally a composite material, which is made of alkali-free glass fiber (e glass fiber) as the main material, uniformly coated with polymer and heated. Although the glass fiber reinforcing yarns are derived from the original glass fiber yarns, they have better processing technology and comprehensive performance than the original glass fiber yarns. The original glass fiber yarn is a very fine and easily dispersed bundle, which is very inconvenient to use. It is very easy to use when evenly coated with polymer.
Applications of Glass Fiber Reinforced Yarns
Glass fiber reinforcing yarn is a good flexible fiber optic cable carrying element, widely used in indoor and outdoor fiber optic cable structures. Water-resistant glass fiber reinforcing yarn has a dual function, both play a tensile function of the fiber optic cable, but also bear the water-blocking function of the fiber optic cable in fact, there is a role, that is, there is a rodent-proof role. It uses the unique puncture characteristics of glass fiber, so that rats are reluctant to bite the fiber optic cable.
In the production of indoor fiber optic cables, because the outer diameter of the cable is relatively small, so most of the glass fiber reinforcing yarns are placed in parallel in the cable to protect the optical fiber in the cable. It should be said that the process is relatively simple
Outdoor fiber optic cable production, a large number of glass fiber reinforcing yarn, usually armored. The cable is usually released with a cage equipped with multiple fiber yarns, which rotate to wrap the glass fiber reinforcing yarns around the core of the fiber optic cable. The tension of the glass yarns needs to be controlled to ensure that the unwinding tension is uniform for each yarn.
