Nylon
Nylon is a durable fiber that has good resiliency and good stain resistance. It is a strong fiber, which makes it suitable for the heavy traffic of a commercial area or active household. It is typically more expensive than olefin and polyester based carpet.
Polyester
Polyester fiber has some of the most beautiful textures and colors available, and is durable and resists wear. It is susceptible to crushing, but has excellent resistance to stains. Most polyester-based carpets have a luxurious feel (hand) that people love to dig their fingers into.
