Processed into women's stockings, nylon made a public career worldwide. However, the first completely synthetically produced synthetic fibre was first used in the general public, namely as toothbrush bristles . With the entry of the USA into the Second World War, however, the importance of nylon also increased as a material important for defence. The military recognised the benefits of this extremely light but highly robust synthetic fibre and used it to manufacture parachutes, tents or camouflage nets. However, it was not only the military who were convinced by the property profile of polyamide: what had proven itself in security-relevant areas during the war quickly found use under civilian conditions as well.
It was therefore only a matter of time before nylon fibres were also used in the world of high alpine sports and high-altitude rescue. Since their introduction, i.e. that of climbing and mountaineering ropes made of nylon fibres, the number of fatal falls in the mountains due to rope breaks has decreased significantly. Nevertheless, it sounds almost paradoxical, "if climbers are connected by a rope, the risk of falling can increase drastically", Holger Kreitling quotes a training manager at the German Alpine Association in his Welt article "Die falsche Sicherheit der Seilschaft" . However, the author provides an important argument for this thesis: without fixed points that can actually withstand the load, the rope "conveys a false sense of security", Kreitling writes. It is not only the material and its property profile and quality that matter, but also, in a very special way, the person and his or her specific skills and experience in handling and dealing with the material .
