A rope (English: rope) is a type of cordage [1]. Generally, ropes and cords are considered ropes. In Japanese, it is translated as "saku" (索) [2]. There are fiber ropes (textile ropes, fiber ropes) made by twisting natural or synthetic fibers together, and wire ropes (steel ropes) using steel wires [3]. There is no clear definition or distinction between strings, ropes, and cords made by twisting fibers together [1]. Generally, they become thicker in the order of thread, string, rope, and cord. In English, there are rope, cord, and twine as terms for cordage [1]. A yarn is a thread made by twisting a specified number of yarns together [1]. Generally, twine increases its diameter by thickening the constituent yarns [4]. On the other hand, ropes and cords increase their diameter by increasing the number of constituent yarns [4]. However, in the case of ropes, the thickness of the yarn also changes to some extent depending on the thickness of the rope [4]. The manufacturing process of a rope can be broadly divided into three stages: yarn, strand, and rope [1]. In addition, those used for mountaineering are often called "zairu," which is the German word for "rope" and is synonymous with the English word "rope."
