What happens if natural fibers are exposed to moisture?

• A. They become more elastic
• B. They are susceptible to mildew and decay
• C. They become less strong
• D. None of the above

Answer: (B)

When natural fibers are exposed to moisture, they are indeed susceptible to mildew and decay. Natural fibers, such as cotton, jute, hemp, and silk, are organic materials that can absorb moisture. When this occurs, it creates an environment conducive to mold and mildew growth, which can lead to deterioration of the fiber over time. This process can weaken the structural integrity of the fibers, potentially compromising their effectiveness when used in applications such as rigging and hoisting. Furthermore, decay can result from prolonged exposure to moisture, leading to a significant reduction in the lifespan of the material. While natural fibers may experience some changes in strength and elasticity when wet, the primary concern is the biological deterioration, making the noted susceptibility to mildew and decay the most critical outcome of moisture exposure in this context.
