Does paracord lose strength when wet?

Impact of Water on Paracord Strength

Paracord, like many other types of cordage, experiences a significant reduction in strength when exposed to water. This occurs due to the absorption of moisture, which causes the core and jacket fibers to swell and lose their natural crimp. As a result, the internal fibers become less effective at distributing tension, leading to a loss of strength.

Factors Affecting Paracord Strength in Water

The extent to which paracord loses strength in water depends on several factors, including the type of fibers used, the thickness of the cord, and the duration of exposure. In general, paracord with a 5mm or 7mm core will retain its strength for a longer period than a 3mm or 4mm core. Additionally, cordage that has been treated with water-repellent coatings or finished with a water-resistant wax may exhibit improved performance in wet conditions.

Techniques for Preserving Paracord Strength

To minimize the impact of water on paracord strength, it’s essential to take preventative measures. One effective technique is to apply a water-repellent coating, such as silicone or beeswax, to the cord. Another approach is to use a cord with a hydrophobic (water-repelling) treatment, which can reduce the absorption of moisture. In addition, cordage can be dried and stored in a way that minimizes exposure to humidity and moisture, such as by wrapping it around a dry core or storing it in an airtight container.
