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.
The UIAA Water Repellent Test makes the water-repellent properties of ropes measurable. The test samples are first subjected to a mechanical abrasion test, as occurs in practice in the use in rock and ice. Subsequently, the test sample is watered according to a standardized method in a defined time and with a defined amount of water. The proportion of absorbed water must not be more than 5 % of the self-weight of the rope. Ropes meeting these requirements may be designated as "UIAA water epellent".
