Synthetic rope is made from specialized fibers. There are several different fibers used in the creation of these ropes, but Kevlar, Technora and Vectran, Specta, and Dyneema are the most popular synthetics used in the winch rope creation. You will find some of the ropes crafted from nylon.
These materials are used because they do not stretch as easily as natural fibers like cotton. They are resistant to damages from the sun, heat, and water. They also have strength that is surprising from such lightweight items.
All synthetic ropes are made from twelve pieces of the material and then those pieces are braided together to make one strong rope.
