We apply complex finishing treatments to make our ropes durably water- and dirt-resistant. This prolongs their service life and gives them their tried and tested EDELRID handling and flexibility.
Untreated ropes can absorb up to 50 % of their own weight in water. When wet, such ropes become extremely heavy, difficult to handle and may freeze in cold conditions. Moreover, their safety reserves are compromised. This is why dry treated ropes are used for activities where ropes are more likely to get wet, such as ice climbing or mountaineering. Pro Dry is a new finishing process, which provides a solution to this problem. First the core yarns are infused. Then, once braiding is completed, the finished rope (core and sheath) is infused again. In a final stage, the dry treatment is thermally fixed. The result is a rope that is durably water repellent and dirt resistant. Pro Dry ropes are particularly quick drying, absorb virtually no water and are resistant to freezing in cold temperatures. Due to their minimal water absorption (1–2 %) in accordance with the UIAA water-repellent test, Pro Dry ropes hardly increase in weight. As such, they continue to perform well and provide high safety reserves even in wet conditions.
In the UIAA Water-repellent test, Pro Dry ropes have water absorption of just 1–2 %
The UIAA water-repellent test is a new standard and test developed by the UIAA to measure the water repellency of ropes. During the test, a rope sample is first subjected to mechanical surface abrasion over its entire length. This simulates the wear a rope is exposed to in practice on rock and ice. In a standardized procedure, the rope sample is then fixed to a slanted table and undergoes a defined water flow (2 l/min) for 15 minutes. The rope sample is weighed before and after the water flow. Finally the difference between these two values is calculated and expressed as a percentage. The amount of absorbed water must not be greater than 5 % of the rope sample's weight. Ropes that meet these requirements may be labeled as UIAA Water Repellent.
