Which fibers are less resistant to water damage?

Natural fibers are less resistant to water damage due to their inherent characteristics. These fibers, such as wool and cotton, can absorb water, leading to swelling, mildew, and degradation over time if they remain wet. The cellular structure of natural fibers makes them more prone to the adverse effects of moisture, as they absorb water readily, which can result in warping, color fading, or even structural damage.

In contrast, synthetic fibers, such as polyester and nylon, are designed to be more resistant to moisture and often have properties that repel water. Acrylic fibers also demonstrate good water resistance and are less susceptible to damage caused by moisture compared to natural fibers. Therefore, while synthetic and acrylic fibers can withstand water exposure better, natural fibers do not have those same protective attributes, making them more vulnerable to water-related issues.
