The rope is reinforced by twisting or knitting to form a certain length of fiber. It has good tensile strength but no compressive strength, and can be used as a tool for connection and traction. In 2800 BC, the ancient Chinese had mastered the technology of creating hemp rope and began to use hemp fiber to make rope. By the beginning of the A.D., hemp fiber had become the main rope making material in most parts of the world. In 1775, British inventor Marceau invented the rope making machine, ending the era of manual rope making. Ropes have been made from man-made fibers since 1950.

Ropes can be classified in a variety of ways. Flax rope and Gastrodia rope belong to natural fiber rope, while Kevlar rope and Vectran rope belong to chemical fiber rope; According to the classification of manufacturing technology, it can be divided into twisted rope, braided rope and parallel fiber rope; According to the diameter of rope, it can be divided into rope, rope and cable; It can be divided into marine rope, agricultural rope and so on; It can be divided into military rope and civil rope according to the use background.
