Which factor contributes to the deterioration of natural fiber ropes more quickly than synthetic ropes?

Natural fiber ropes are more susceptible to deterioration due to exposure to moisture when compared to synthetic ropes. Natural fibers, such as manila and sisal, can absorb water, which can lead to weakening of the fibers, mold growth, and eventual breakdown. This moisture absorption not only impacts the tensile strength of the rope but also makes it more prone to rot and degradation over time.

In contrast, synthetic ropes are typically designed to resist moisture, which enhances their longevity and durability in wet conditions. This inherent quality makes natural fiber ropes less optimal for environments where they might be frequently exposed to water, such as in marine settings or outdoor applications. Thus, the factor of exposure to moisture is a significant reason why natural fiber ropes deteriorate faster than their synthetic counterparts.
