In the past, steel, hemp or cotton ropes were commonly used; since the appearance of synthetic fibers, the synthetic fibers are mostly made of chinlon, polypropylene fiber, vinylon, terylene and the like. The synthetic fiber cable has the advantages of light specific gravity, high strength, good impact resistance and wear resistance, corrosion resistance, mildew and rot resistance, insect damage resistance and the like. For example, the strength and the wear resistance fastness of the nylon mooring rope exceed the strength and the wear resistance fastness of hemp and cotton mooring ropes by a plurality of times, the specific gravity of the polypropylene mooring rope is smaller than that of water, and the nylon mooring rope can float on the water surface, so that the operation is convenient and safe. The chemical fiber cable is divided into two types of 3 strands or multi-strand twisted cables and 8 strands or multi-strand braided cables according to the processing structure. The common diameter of 3 stranded hawsers is 4 ~ 50 millimeters, and the common diameter of 8 stranded hawsers is 35 ~ 120 millimeters. The chemical fiber mooring rope is widely used in the fields of transportation, industry, mines, sports, fishery and the like besides being used for ship mooring ropes. According to the requirements of special purposes, metal materials can be further woven in the cable core.

Cables are used in many places because the cables are relatively strong, the existing cables have impact resistance and wear resistance, but the impact resistance and wear resistance are far from sufficient, and the existing cables have no fire resistance, thereby resulting in a short service life of the cables. And need to be replaced frequently.
