Nylon carpets are some of the most durable and easy to clean because they are strong and resilient. They stand up well to abrasion, which means they will last a long time. The fibres also keep their original texture when brushed whereas lower-quality carpet materials may not retain the shape over time and flatten.
Triexta is a newer corn-starch originating material which allows carpets to be even more stain resistant and easier to maintain than solution dyed nylon.
