What fiber is commonly used in outdoor rugs and heavy-use upholstery?

Olefin is commonly used in outdoor rugs and heavy-use upholstery due to its exceptional durability and resistance to moisture and fading. This synthetic fiber is known for its ability to withstand exposure to the elements, making it ideal for outdoor settings where rugs may face rain, sun, and temperature fluctuations. Additionally, olefin is resistant to staining and easy to clean, which enhances its appeal for upholstery in high-traffic areas. Its lightweight nature adds to its versatility, allowing for easy handling and maintenance.

In contrast, cotton is more susceptible to mold and fading when exposed to outdoor conditions, making it less suitable for prolonged outdoor use. Silk, while luxurious, is not durable enough for frequent use or outdoor settings, as it can be easily damaged by moisture and UV rays. Rayon, although it can simulate the appearance of natural fibers, does not possess the same level of durability and moisture resistance as olefin, making it less practical for heavy-use upholstery and outdoor applications.
