Which of the following types of ropes is NOT considered a synthetic fiber rope?

Wire is not considered a synthetic fiber rope because it is made from metal, typically steel or another type of metallic material. While synthetic fiber ropes are made from polymers and designed to be lightweight, strong, and resistant to various environmental factors, wire ropes utilize a completely different material composition and structure.

Nylon, polypropylene, and polyester are all types of synthetic fibers. Nylon is known for its high tensile strength and elasticity, making it ideal for various applications. Polypropylene is lightweight and resistant to moisture, while polyester offers high strength and excellent resistance to UV degradation. These characteristics make synthetic fiber ropes suitable for rigging and other applications where flexibility, weight, and resistance to the elements are essential. In contrast, wire ropes, while strong and durable, do not fall under the category of synthetic fiber due to their metallic nature.
