What is a common characteristic of olefin fiber in terms of resistance?

Olefin fiber, also known as polypropylene, exhibits a common characteristic of being resistant to moisture. This resistance is significant because it means that olefin fibers do not absorb water, which helps prevent the growth of mold and mildew in damp environments. This quality makes olefin ideal for both indoor and outdoor carpeting, as it maintains its integrity and appearance in various humidity levels.

In addition to its moisture resistance, olefin fibers are known for their durability and are often used in high-traffic areas due to their strong resilience. They are also less flammable compared to other fibers, which adds to their safety in residential and commercial settings. The characteristic of being absorbent or low durability does not align with the fundamental properties of olefin, reinforcing the importance of moisture resistance as a defining feature.
