CUT PROTECT
New braiding process enables increased cut resistance.
BRAIDING PROCESS CUT PROTECT
Give Sharp Edges the Cold Shoulder
The development of a new braiding process and the combination of high-strength aramid and polyamide fibers allow us to produce ropes with a high cut resistance.
While problems such as acid contact and friction burns can be excluded as far as possible through proper application and storage, edge loads are still a problem.. The edge does not even have to be particularly sharp.
It becomes particularly problematic when there is a pendulum movement over an edge (e.g. when abseiling or lowering). Then, in addition to the edge load, a cutting load occurs, which can have fatal consequences. The rope is cut through, so to speak. How can we mitigate these risks?
At EDELRID we have tackled the problem and developed a rope that has a particularly high cut resistance. This is made possible by the new "Cut Protect" rope technology. This means high-strength aramid fibers are braided into the rope sheath during the braiding process. Compared to polyamide, aramid has a significantly higher cut resistance.
The crux:
aramid is a particularly static material. Compared to polyamide, it has virtually no dynamic properties. However, in the event of a fall, it is necessary to absorb the resulting energy and thus reduce the impact force to a tolerable level.
Since the current standard for dynamic mountain ropes does not include a test procedure for assessing the cut resistance, at EDELRID we have developed a special machine that simulates this load under laboratory conditions. The internal comparison of the Swift Pro Dry and the Swift Protect Pro Dry shows that ropes with Cut Protect technology have
almost twice as much cut resistance as conventional mountain ropes.
