Which fiber is known for its high resilience and ability to retain its shape?

The chosen fiber, polyester, is renowned for its high resilience and ability to retain its shape. This characteristic makes polyester an excellent choice for carpets and upholstery that experience regular foot traffic or usage, as it can withstand the wear and tear while maintaining its original appearance. Polyester fibers are designed to bounce back after being compressed, which helps minimize flattening and stretching over time, leading to a longer lifespan for carpet installations.

Additionally, polyester is resistant to many common stains and is often treated for added durability, further enhancing its performance in various environments. Its ability to hold color well also contributes to its aesthetic appeal, allowing for vibrant designs that remain vivid over the life of the carpet.

In contrast, while wool is naturally resilient, it does not have the same level of durability and shape retention as polyester, especially under heavy use. Acrylic, while soft and lightweight, lacks the necessary durability overall, and olefin tends to be less resilient in terms of retaining shape and elasticity compared to polyester.
