Climbing rope is the most important equipment in mountaineering both in history and today. Various climbing techniques such as ascent, descent and protection are all developed around climbing rope. Iron locks, seat belts, and many other mountaineering supplies can only function when they are connected with climbing rope. The early climbing rope was made of cotton, and then developed to use hemp. After the 1950s, it was changed to nylon fiber with excellent performance in many aspects such as tensile strength, durability, and abrasion resistance.
Modern climbing rope is designed and produced according to the requirements of modern mountaineering. Climbing ropes are all woven ropes with a layer of outer net on the outside of several twisted woven ropes instead of ordinary nylon ropes. According to the different requirements of use, there are mainly two kinds of wear resistance and friction. The outer net of climbing rope is also divided into two kinds of single weaving or double weaving. Generally speaking, climbing ropes with single-woven outer nets have lower friction and are more wear-resistant. There are many colors of climbing rope. Generally speaking, the ropes used by different members of the same climbing team are best to be separated in color so that no items will be lost during technical operations.
