How does polyester fabric compare to canvas in terms of resistance to decay?

When comparing polyester fabric and canvas in terms of resistance to decay, several factors come into play. Polyester, a synthetic material, is highly resistant to decay due to its chemical composition, which makes it less susceptible to mold, mildew, and rot. This makes polyester an excellent choice for outdoor applications, such as awnings, tents, and marine covers, where exposure to moisture and harsh weather conditions is common.

Canvas, on the other hand, is a natural fabric typically made from cotton or linen. While canvas is durable and strong, it is more prone to decay over time, especially when exposed to moisture and UV rays. Without proper treatment or maintenance, canvas can develop mold, mildew, and rot, reducing its lifespan.

In summary, polyester fabric outperforms canvas in terms of decay resistance, making it a more durable option for long-term use in challenging environments. However, canvas remains a popular choice for its natural feel and aesthetic appeal, particularly when treated with protective coatings to enhance its resistance to decay.
