Can Weather Exposure Weaken Cordage Over Time?

Material Degradation

Weather exposure accelerates the degradation of cordage materials, including plant fibers, animal sinew, and synthetic materials. Prolonged exposure to sunlight, moisture, and extreme temperatures can break down the molecular structure of these materials, reducing their tensile strength and overall durability. For instance, a well-made cordage made from plant fibers may lose up to 50% of its tensile strength after just 30 days of exposure to direct sunlight.

Reverse Wrap Technique

To mitigate the effects of weather exposure on cordage, it’s essential to employ proper storage and maintenance techniques. One effective method is the reverse wrap technique, where the cordage is wrapped in the opposite direction of its natural twist. This helps to prevent the fibers from rubbing against each other, reducing friction and wear. When reversing the wrap, it’s crucial to maintain an even tension to avoid creating creases or kinks that can further weaken the cordage.

Cordage Inspect and Replace

Regular inspections are vital to detect any signs of degradation or damage in cordage. Check for frays, cracks, or discoloration, which can indicate moisture or chemical damage. If you notice any of these signs, it’s time to replace the cordage with a new one. As a general rule, it’s recommended to replace cordage every 6-12 months, depending on usage and environmental conditions.
