The breaking strength of the rope will be lost after light. Although other properties such as abrasion resistance and flexibility will also be affected, it is not as significant as the breaking strength. The impact of light on the rope mainly depends on the light and time light intensity. The light intensity at low latitudes…
In actual use, the rope will be affected by various environmental loads such as light, humidity, temperature and chemicals. When the conditions of use, environmental conditions and duration of use change, important properties such as the breaking capacity and elongation of the rope will also change. 1. The influence of light on the rope The…
Macrame Rope: What is the difference between three-strand cotton rope and cored yarn? 1. The difference in appearance: Three-strand cotton rope: The delicate yarn is divided into three strands and twisted in the same direction. The tail of the three-strand thread can be divided into three strands, or all can be combed and scattered into…
Processing technology: ordinary thread and wax thread Normal line: the line without post-processing Wax thread: After the thread is made, it is processed at high temperature or soaked in wax. Common wire name The combination of these different angles will form a common wire on the market. Commonly used strands: 3 strands, 6 strands, 9…
When you start learning to knit, you will definitely be dizzy with various threads. Let’s take a look at the types of threads used for knitting. First classify them from different perspectives: Weaving process: strand and braid Strand: A thread formed by twisting two or more single yarns together. Braided thread: multiple single yarns or…
Check the climbing rope after each use. The best inspection tool is your hand. They can sensitively detect abnormalities on the climbing rope, such as a sudden flattening of a place, a feeling different in thickness from other places, or a particularly loose section. The rope must not pass directly through bolts, fixing points, umbrella straps,…
Do not step on the rope whether you are wearing socks or barefoot. Stepping on it will allow some invisible sand particles to penetrate into the rope, and slowly cut the rope skin or rope core fiber as it is used. In addition, you must be very careful not to step on the rope when…
Maintenance of climbing ropes A climbing rope that suits you must be carefully selected and cared for. After daily outdoor climbing, remember to take good care of it to better extend the life of the climbing rope. Maintenance points: Try not to lend your rope to others unless you want to climb with him. Don’t…
Several knotting methods of climbing rope 1. Backed-up Square knot half knot plus double fishing knot. This method is the best choice for connecting two ropes, because it is easier to untie after bearing the weight. 2.Double fisherman’s knot Double fisherman’s knot. It is most suitable for connecting rope loops (runner) or rope that is…
For the safety of climbers, UIAA stipulates that the ductility of the power rope should be less than 8%, otherwise the climbing rope will be turned into a bungee rope, causing climbers to bump up and down on the rock wall, which is very dangerous. There is also a type called static rope. The ductility…
The climbing ropes can be selected in the following order: A. The ropes are divided into power ropes and static ropes: in projects with the possibility of a dynamic fall, you must use a power rope: rock climbing, mountaineering, descent, bungee jumping. At this time, the extension of the rope is used to absorb energy.…
The average climber always thinks that the pulling force of the climbing rope is an important technical parameter. In fact, for climbing ropes, the maximum pulling force is generally not marked, but the impact force, ductility and the number of drops of the International Board parameter. Here we must first explain the requirements of climbing…
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…
Waterproof alimbing rope is what we often call dry rope. The outer net of this kind of rope is generally treated with TEFLON waterproofing. The strength of the rope will decrease by more than 20% after being soaked in water. In mountain climbing, the strength of non-waterproof ropes will be greatly reduced after being soaked…
Anti-cutting index The sharp angle will have fatal consequences for the horizontal cutting of the rope. When the rope is bearing the weight, the rope can be easily cut with a sharp object. In UIAA’s standard anti-cutting test, it is required to drop an 80 kg weight from a height of 5 meters, and the…
